version: "1.0.1" name: greenlight description: | Automated PR review loop that keeps running until the PR is clean. Triggers external reviewers (Codex bot, Codex CLI, and the Gemini bot when activity detection sees it on the repo), processes feedback, fixes issues, and re-triggers — repeating until no new suggestions remain. Supports /greenlight external to skip internal review and go straight to external reviewers, and /greenlight external gemini to specify a starting reviewer. Use when the user says "greenlight", "run reviews until clean", "get this PR approved", or wants automated review cycling on an open PR.

Also auto-detects uncommitted mode: when on main branch with uncommitted changes and no PR, runs Codex CLI --uncommitted review loop only, fixes in-place without committing, until codex reports clean.

Also supports post-commit mode (explicit /greenlight post-commit <SHA> or <SHA1>..<SHA2>): Phase 1 subagents + Codex CLI + agy (Gemini-family CLI) in parallel, fixes as new commits on top (no amend, no new PR), pushes after each round.

Greenlight

Automated review loop. Three modes:

• PR mode (default, for open PRs on feature branches) — three phases:

`` Phase 1: Internal Review (subagents review in parallel, report-only) Phase 2: Consolidate + Fix (merge reports → fix via /receiving-code-review → commit + push) Phase 3: External Review Loop (Codex/Gemini/CodeRabbit cycle until clean) ``

• Uncommitted mode (auto-detected when on main + uncommitted changes + no PR):

Codex CLI --uncommitted loop only. Fixes in-place, does NOT commit.

• Post-commit mode (explicit /greenlight post-commit <SHA> invocation only,

no auto-detect): Phase 1 subagents + Codex CLI --commit <SHA> + agy in parallel; merge findings; fix as new commits on top (no amend, no new PR). Skips PR-bound bots.

Host support

On Claude Code this skill is fully supported: every mode, every phase.

On Codex it is `degraded` — it runs on exec, TUI, and App with a documented smaller surface:

Limitation reference: docs/spec/2026-08-10-codex-greenlight-port.md. The filtered Codex publication includes this degraded surface. Reviewed-head binding remains a shared Claude/Codex defect, not a Codex parity gate.

Phase 1 is verified on Codex exec only (docs/spec/2026-08-15-codex-greenlight-phase1.md). TUI and App run the same shared body with no surface gate, so Phase 1 is expected to work there and is simply unproven; if it does not, the all-reviewers-unavailable rule already carries those runs to Phase 3. Phase 3 itself is accepted on all three surfaces.

Arguments

Parsing rules:

• post-commit keyword (case-insensitive): forces post-commit mode regardless of repo

state. Remainder is the SHA spec (single SHA, FROM..TO range, or empty to ask). Other args are ignored.

• external keyword (case-insensitive): PR mode only. Remainder is the reviewer spec.
• unattended keyword (case-insensitive): fail-fast, no prompts. Stripped before

reviewer-spec parsing; combinable with any mode.

• size= token (case-insensitive, value s/m/l): advisory size for the

S/M/L profile, used in PR mode. Stripped before reviewer-spec parsing, like unattended; a malformed value is ignored. Not read in post-commit mode (it computes size from the resolved range) or uncommitted mode (unsized).

• select= / gate= tokens (case-insensitive): PR mode only. Stripped before

reviewer-spec parsing on the same line as unattended and size= — a token left in the remainder becomes part of the reviewer spec, so gate=codex-bot would be looked up as a reviewer named gate=codex-bot and miss on every lookup thereafter. Unknown or since-marked ids degrade with a warning inside resolve; they never fail the run.

• No keyword: mode comes from auto-detection (see Step 1 table).

Arguments other than post-commit are ignored in Uncommitted mode and Post-commit mode — those modes have fixed flows.

Verification gate

An optional adversarial verification gate can run between consolidating review findings and dispatching a fix subagent: each consolidated finding is independently challenged by 3 skeptic subagents inside one Claude Code Workflow, and findings a majority of skeptics refute are dropped. Only survivors reach the fix subagent. Purpose: cut false-positive fix cycles — a wrongly "fixed" false positive costs a whole extra review round.

Availability check. The gate runs ONLY when BOTH conditions hold: the effective size is L (see Sizing — S and M skip the gate regardless of tooling), AND the Workflow tool is present in the current session (Claude Code v2.1.154+, paid plans). Before each gate, check both:

• Size L and `Workflow` present → run the gate. The script, VERDICT_SCHEMA,

args contract, verdict rule, and result mapping are defined once in references/adversarial-verify.md.

• Size S or M, or `Workflow` absent → **skip the gate entirely; the flow is

exactly today's flow** — hand every consolidated finding straight to the fix subagent. The gate is never a hard dependency of greenlight.

The gate applies at exactly three points, each carrying a short callout below: PR-mode Phase 2a→2b, Post-commit Phase 1→Phase 2, and Post-commit Phase 3 Step 3→Step 4. It does NOT apply to Uncommitted mode or PR-mode Phase 3 (external review threads carry GitHub resolve/reply obligations and are already evaluated per-thread through receiving-code-review).

Rejected findings still count. Gate-rejected findings count as "items pushed back" in the final report, and their reasoning must be carried into later rounds' "prior push-backs" context so a repeat finding can push-back-exit.

Inner verify loop (objective verifier gate)

Every fix dispatch that ends in a commit is wrapped in an inner verify loop: after the fix subagent edits, it runs an objective verify command against the working tree before committing, and may commit + push only once that command passes. This is a different question from the reviewer-clean stopping criterion — keep the two roles separate:

• Verifier (objective, runs code) — gates whether a fix may push. It

executes the repo's own lint / typecheck / fast-unit command and observes real behavior (import errors, type errors, regressions).

• Reviewer-clean (subjective, reads diffs) — gates whether the outer loop may

stop. Codex / agy read the diff statically; they cannot run code, so they are not verifiers. Do not conflate the two, and never position codex/agy as the verifier.

Applies to the PR-mode Phase 2b, PR-mode Phase 3 (Step 3b), and both Post-commit fix dispatches (Phase 2 initial fix and Step 5). Uncommitted mode is exempt — it never commits, so there is nothing to gate; leave it as-is.

Resolving the verify command

The orchestrator resolves the command once, before the first fix dispatch of the run, and passes it into each fix subagent prompt. Source the config helpers in the same bash block — the marker block from Pre-flight Step 2, copied as-is — then:

# `verify` is stored as { "cmd": "<command>" }; pull the string out. An unset key
# makes read_* print nothing → jq gets empty stdin → 2>/dev/null keeps the block
# alive and VERIFY_CMD ends up empty.
VERIFY_CMD=$(read_solopreneur_config verify | jq -r '.cmd // empty' 2>/dev/null)
[ -z "$VERIFY_CMD" ] && echo "NO_VERIFIER" || echo "VERIFY_CMD=$VERIFY_CMD"

• `VERIFY_CMD` empty (`NO_VERIFIER`) → skip the inner loop entirely; the fix

subagent commits exactly as it does today. Add one flag-style line to the final report: "no objective verifier configured for this loop" (see Flags below). Never invent a command.

• `VERIFY_CMD` set → pass it into every fix subagent this run, together with

the inner-loop instructions below.

Inner loop (inside the fix subagent)

The loop lives INSIDE the fix subagent's instructions — the subagent owns edit → verify → iterate and only commits on a green verify. When VERIFY_CMD is set, add this block to the fix subagent prompt (on top of that path's own commit-message and hard-constraint instructions):

You have an objective verify command: <VERIFY_CMD>. Before you commit:
 
1. Apply your fix edits to the working tree.
2. Run <VERIFY_CMD> against the working tree. Do NOT commit first — lint /
   typecheck / fast-unit are working-tree operations, so verify-before-commit
   holds in EVERY mode, post-commit included (no "broken commit + fix commit"
   sequence is ever created).
3. Pass (exit 0) → proceed to the commit + push step already specified for this
   path (unchanged commit message).
4. Fail (non-zero) → do NOT commit. Feed yourself back only a TRUNCATED log — the
   final failing assertion / first error line plus the tail, capped in size the
   same way this file caps agy input at AGY_MAX_DIFF_BYTES — and retry the fix.
5. Cap: 3 verify attempts total. On the 3rd consecutive failure, do NOT commit or
   push — return a structured halt result (reason `inner-verify-failed`,
   `reason_class: invariant-violation`, the FULL verify log, your attempted-fix
   summary) instead of committing.
 
Truncate every feedback log this way; the full log rides only in the halt
payload. Three stacked rounds of full logs would otherwise drown the signal.

Anti-gaming guard (before every commit)

The cheapest way to make a failing verify "pass" is to edit the tests or the verify command itself. The subagent must check, before it commits: for every test file or verify-definition file the fix diff touches, this round's findings must explicitly reference that same file. If the diff touches a test file or the verify definition that no finding called out → do not commit. Match per file — a finding about one test file does not license editing a different, unmentioned test file. In both modes the immediate action is the same — do not commit — with the reason anti-gaming: fix touches test/verify definition unprompted; the level differs only in what follows. Unattended halts the loop (its halt payload carries reason_class: authority-boundary → the orchestrator blocks); attended flags it and lets the present human adjudicate the suspected gaming. This is the one deliberate unattended-halt / attended-flag split (a suspected gaming edit is cheap to adjudicate live), an intentional exception to the usual halt→ask projection noted in the Escalation taxonomy. At size S (added by a later PR) there are no internal reviewers, so this guard is the only defense against fix-to-pass gaming — it lands here, not in the escalation PR.

Halt / flag primitive

The level model that assigns halt / flag / note, the two-question rubric, reason_class, the attended projection, and the findings-contradiction table all live in Escalation taxonomy. This subsection is the operational primitive the inner verify loop uses: how a halt is written and what the orchestrator must do when one fires.

• halt — stop the loop and do not commit. Write a payload file — last round's

findings + the FULL verify log + attempted-fix summary + a `reason_class` (transient-dependency / invariant-violation / authority-boundary — retry semantics in Escalation taxonomy) + suggested next step — under docs/loops/<run>/halts/ when running inside an autopilot run dir, else the standalone fallback docs/loops/<date>_greenlight-<branch-slug>/halts/ (<date> = YYYY-MM-DD, <branch-slug> = current branch with every / replaced by -, so a slashed name like feature/x stays one flat directory instead of nesting). Reference the path in the final report. Unattended semantics: report blocked and exit non-zero. Attended: surface the payload path and ask the user how to proceed.

• Orchestrator obligation. Every fix dispatch below can return a halt

instead of committing. When it does, route straight to that mode's blocked exit: do NOT run the post-dispatch push verification (a halt leaves HEAD == origin/main, which would false-pass a HEAD != origin/main check), do NOT resolve review threads, and do NOT start another round.

• flag — do NOT stop; keep looping, but record the event in a dedicated,

prominent Flags section of the final report (below) for a human to adjudicate afterward.

Flags section (final report)

When any flag fired (no verifier configured, an attended anti-gaming catch, an auto-classified size S without an explicit override, a `DETECTION_STATUS` of `unavailable`, and the other flag sources in Escalation taxonomy — a pushed-back P1, a fix over 20 lines, a merge with no CI signal, findings contradictions ① and ②), append a prominent section to whichever mode's final report runs:

## Flags (human review suggested)
- <flag reason 1>
- <flag reason 2>

Omit the section entirely when nothing flagged.

Worst-case work bound

The inner loop is a newly multiplied retry layer, so make the nesting explicit. The wave ×2 wraps, per attempt, one implement pass followed by the greenlight loop; within an attempt those two stages run in sequence, so their counts add, they do not multiply. Autopilot's Step 3 self-fix ×3 runs during implement, then greenlight's outer review rounds — now per size (S 3 / M 5 / L 10; see Sizing) — each wrap inner verify ×3. At the L ceiling that is 10 × 3 = 30 fix attempts, so a single PR-mode L PR under autopilot tops out near 2 × (3 + 10 × 3) = 66 fix attempts; a default M PR is 2 × (3 + 5 × 3) = 36 and an S PR is 2 × (3 + 3 × 3) = 24 — the self-fix stage is additive with the review rounds, not a multiplier on them. The inner loop multiplies fix work per round; a repo whose verify command is slow pays for it here — which is why verify must stay fast and E2E stays in CI (see config verify key).

Escalation taxonomy (halt / flag / note)

Every escalation in this skill resolves to one of three levels. The model is unattended-first (greenlight runs unattended under autopilot / todos-babysit), with an attended projection for manual runs. The operational mechanics — how a halt payload is written, the orchestrator's obligation on a halt — live in Halt / flag primitive; this section is the model that assigns a level.

Two-question rubric

Assign a level by asking, in order:

1. Can the loop still continue? A mechanical block — every reviewer tool is down,

the environment is broken, the round budget is spent, an invariant is violated — is a halt. Not negotiable.

1. Is this decision mine to make? Three checks: reversibility (can a wrong call

be undone cheaply?), scope (is it inside the spec / size authorization?), and adjudicability (is there a test or spec that mechanically decides right from wrong?). A decision that is expensive-if-wrong, or that cannot be mechanically adjudicated → escalate to a human (flag, or halt when it also blocks the loop). Everything else → act autonomously and leave a trace (note).

The three levels

The flag middle tier is what makes unattended running safe: without it, an unattended run could only choose between halting on everything and running fully autonomously with no human ever told. Keep the Flags section signal-dense — correctness-flavored events only; style noise stays at note (see contradiction ⑤).

reason_class (halt retry semantics)

Every halt payload carries a `reason_class` so a downstream orchestrator can route retry-vs-blocked without re-deriving intent:

reason_class governs only the unattended halt's retry routing; it does not dictate the attended projection (that is set by the level — see Attended projection). The two are independent axes: the anti-gaming guard writes an authority-boundary payload when it halts unattended, yet its attended level is deliberately flag, not the usual halt→ask (the one documented exception — see Anti-gaming guard).

The autopilot orchestrator consumes this from the halt payload greenlight references in its report — see ../autopilot/references/orchestrator.md (failure table).

Attended projection

The three levels are unattended-first, but greenlight is also run manually, and the flow is full of "ask the user" branches. Attended runs project the levels — with no regression to existing interactive behavior:

The distinction is not "prompt vs. no prompt" — it is whether the loop can proceed. A halt cannot continue without the answer (attended blocks on it; unattended exits); a flag always has a defined next move (unattended records + proceeds per the level / table), and attended merely surfaces it — keeping any pre-existing prompt — so the human can redirect. So every existing "ask the user" behavior maps on with no regression: the reviewer-exhaustion wizard is a halt (ask and wait); an ambiguous consolidation and the ">20 lines discuss first" note are decision-point flags (surfaced with their prompt intact).

Findings-contradiction handling table

Reviewers can contradict each other (or the spec), and the verification gate's skeptics validate each finding independently — they never cross-compare, so both sides of a contradiction can survive. Conservative side = leave the current state untouched (no-action), never guess one side and execute it. Unattended disposition:

Attended runs keep asking — ①② are decision-point flags and ③'s dangerous-path case is a halt; either way the attended projection surfaces the existing user prompt (the flag inline, the halt blocking). One-line summary: mechanically adjudicable → let the spec judge; otherwise leave the state untouched — flag the correctness-grade contradictions, note the style ones; the only halt is a fix that crosses the authorization boundary.

Where the existing sites map

The taxonomy re-labels existing behavior; only two behaviors change (contradictions no longer ask the user in unattended runs — the table above; and the orchestrator now defers its round bound to greenlight — orchestrator.md). The scattered rules map as:

• Phase 1 all internal reviewers fail → unchanged: skip Phase 1 + 2 and proceed

to Phase 3 (NOT a halt — internal review is optional; external review still runs). See Phase 1 "All fail".

• External fallback exhausted (all reviewers down) → halt,

reason_class: transient-dependency — see Fallback Logic.

• No independent gate (every authorized reviewer shares the host's model

family) → halt, reason_class: authority-boundary — waiting cannot add a reviewer of another family, so this is deliberately NOT routed as retryable. See Host-family independence.

• Post-commit invariant violations → halt, reason_class: invariant-violation —

the invariant guards in Post-commit parsing and the per-round re-checks.

• Fix over 20 lines → flag (a decision-point flag: attended surfaces it inline

with the existing "discuss first" prompt; unattended records it and proceeds).

• Contradictory findings → the

table above.

• Inner verify 3× fail → halt, reason_class: invariant-violation — see

Inner verify loop.

• Anti-gaming catch → the deliberate unattended-halt / attended-flag split from

the verifier PR: "do not commit" holds in both modes; unattended halts the loop (payload reason_class: authority-boundary), attended flags it for the present human to adjudicate. See Anti-gaming guard.

Sizing (S/M/L risk profile)

Not every PR needs the full review weight — a one-line docs fix and a payment-path refactor should not run the same five reviewers for ten rounds. Greenlight classifies each run by risk into S / M / L and gates the expensive phases on the result. PR mode and Post-commit mode are sized; Uncommitted mode is exempt — it is a local, no-commit, interactive flow, keeps its own fixed loop, and never computes a size.

Mechanical cascade (bash-computable, no LLM judgment)

Size is computed from the real diff — its file list and line counts — by a deterministic cascade. No model judgment enters the classification. The asymmetry is deliberate: L is OR (any one danger signal escalates) while S is AND (every file must be harmless to de-escalate). When the signals disagree, the cascade escalates — L is checked first and wins over S.

1. L — any of these (OR):

• a touched path matches migrations/, auth / payment / crypto code,

.github/workflows/, a Dockerfile / container / infra config (k8s, Helm, Terraform), or a dependency manifest with a substantive change — package.json, requirements*.txt, Pipfile, pyproject.toml, go.mod, build.gradle(.kts), pom.xml, Podfile, and the like (lockfiles excluded — they are generated, not authored);

• OR the diff exceeds ~400 changed lines, excluding lockfiles and generated files.

1. S — all touched files fall inside the whitelist (AND): docs/**

(excluding `docs/loops/** — that is live orchestration config the autopilot reads and executes, not prose), todos/`, the repo-root `README.md` only (plugin READMEs carry install commands and stay out), `LICENSE`, `.gitignore`. Never a global `*.md` glob — in a skill-type repo the product *is* markdown, so a `SKILL.md` change must classify M**, not S.

1. Otherwise → M. Any uncertainty in classification defaults to M.

Config files are deliberately not in the S whitelist: a config error is a silent runtime behavior change, so config edits stay at M. (The former "cross-module boundary" trigger is deliberately dropped — it is not mechanically computable, so it is not part of this cascade.)

Size override & freshness

A caller may pass a size=s|m|l token (see Arguments). It is advisory and upward-only: the size computed from the real diff is authoritative, and the effective size is `max(passed, computed)` on the order S < M < L. A token never lowers the computed size. This makes scope creep upgrade-only and defeats "planned S, grew into M" gaming — a PR scoped size=s that actually touches auth is still reviewed as L.

# EFFECTIVE_SIZE = max(SIZE_ARG token, COMPUTED_SIZE). SIZE_ARG is the `size=` value
# (empty when absent). Upward-only: the token can only RAISE the computed size.

fi

An L-size run on a non-anthropic host halts here, before any reviewer is triggered — write the halt payload with reason_class: authority-boundary and stop. It is not retryable: the host does not change by waiting. The two real fixes are to re-run the loop on a Claude Code host, or to split the PR until it sizes S or M. See Host support.

When the cascade auto-classifies S with no explicit override, add one flag-style line — "auto-sized S — verify" — to the final report (see the Flags section under Inner verify loop).

Profile — what each size gates

Reviewer selection is expressed in the Reviewer Registry vocabulary; no bot login is hardcoded here.

• S behaves like external_only with a 3-round cap: Phase 1 and Phase 2 are

skipped and the run goes straight to Phase 3, still looping to a clean result (S is not a single-pass mode — the cost cap is the round bound, not one shot). Because S is external-only, its one reviewer must actually be available: when no explicit reviewer arg and no fallback_order are configured, resolve the round's gate to the first available external reviewer, preferring codex — codex-cli when its pre-flight CLI gate passed, else a detected github-bot (prefer codex-bot), else the codex-bot default with the existing not-detected warning. This reuses the pre-flight CLI gate and activity detection (registry vocabulary, no hardcoded logins), so an unattended S run uses the authed CLI instead of failing on an absent bot. The codex preference above is the Claude-host one. On a Codex host every codex-family candidate is filtered out of gate selection, so the gate falls to whichever independent candidate is available — claude-cli via the pre-flight CLI probe when it is the only one, which is the common case, but a detected independent bot (coderabbit, bugbot, greptile) is an equally valid gate and the resolver may pick it. There is deliberately no preference among independent reviewers: claude-cli is the host-conditional no-history default (what gets seeded when nothing is known here), not something that outranks a reviewer already active on the repo. With no independent candidate at all the run halts rather than gating on its own family (see Host-family independence). Post-commit S likewise runs a single preferred available CLI (Codex CLI, else agy) rather than the usual codex-CLI + agy pair, shedding the doubled cost.

• The verification gate already runs only when the Workflow tool is present;

sizing adds a second condition — it runs only at size L (S and M skip it even when Workflow is available).

• The inner verify loop is not size-differentiated: every size runs the same

single verify command (see Inner verify loop). Sizing dials review weight, not the objective verifier.

SIZE_MAX_ROUNDS (3 / 5 / 10 for S / M / L) is the Phase 3 loop bound in both PR mode and Post-commit mode.

Pre-flight Checks

Step 1: Mode detection

Determine whether to run PR mode or Uncommitted mode based on current repo state:

CURRENT_BRANCH=$(git branch --show-current)
HAS_UNCOMMITTED=$(git status --porcelain | grep -q . && echo yes || echo no)
# Probe PR existence for current branch (stderr suppressed; no PR → non-zero exit)
if gh pr view --json number,state >/tmp/gl-pr.json 2>/dev/null; then
  PR_EXISTS=yes
  PR_STATE=$(jq -r .state /tmp/gl-pr.json)
else
  PR_EXISTS=no
  PR_STATE=none
fi
# Peek at args (case-insensitive) for the `post-commit` keyword — it forces
# post-commit mode regardless of repo state.
# RAW_ARGS = the args string from the skill invocation; the orchestrator must
# export this before evaluating the snippet.
HAS_POST_COMMIT_ARG=$(echo "$RAW_ARGS" | grep -iq "post-commit" && echo true || echo false)
echo "BRANCH=$CURRENT_BRANCH UNCOMMITTED=$HAS_UNCOMMITTED PR=$PR_EXISTS/$PR_STATE POST_COMMIT_ARG=$HAS_POST_COMMIT_ARG"

Override:

• If HAS_POST_COMMIT_ARG=true AND CURRENT_BRANCH != main, **stop with a clear

error**: post-commit mode is only valid on main (Phase 3 hardcodes main / origin/main checks and would crash on a feature branch). Tell the user to either switch to main or use PR mode (/greenlight on the feature branch with an open PR).

• If HAS_POST_COMMIT_ARG=true AND CURRENT_BRANCH == main AND HAS_UNCOMMITTED=no,

set MODE=post-commit immediately and skip the rest of this table.

• If HAS_POST_COMMIT_ARG=true AND CURRENT_BRANCH == main AND HAS_UNCOMMITTED=yes,

stop and ask the user how to proceed before continuing — options: (A) stash uncommitted changes and proceed with post-commit review, (B) abort, (C) proceed but only stage explicit files for the fix commits. Do NOT auto-include uncommitted WIP in the post-commit fix commits — they would be pushed to origin/main together with the review fix.

Mode table:

The post-commit row is more specific than the stop row — match it first; otherwise fall through to stop.

Mode guard — PR mode only on a non-anthropic host. Run this the moment MODE is decided, before Step 2 and before any side effect:

HOST_FAMILY=$([ -n "${CODEX_THREAD_ID:-}" ] && echo openai || echo anthropic)
if [ "$HOST_FAMILY" != anthropic ] && [ "$MODE" != pr ]; then
  echo "HALT: $MODE mode needs a Claude Code host (reason_class: authority-boundary)"
  exit 1   # stop here, before Step 2 and before any side effect
fi

Halt with reason_class: authority-boundary and stop. Uncommitted and post-commit modes have no gate and never call `resolve`, so the host-family independence below does not reach them at all: their terminal clean signal is codex review's own stdout, which on a Codex host is the host's model family declaring its own work clean. That is the same-family self-approval the gate filter exists to prevent, arriving through a door the filter does not watch. Host support already scopes Codex to PR mode; this is the check that makes the scope real rather than merely documented. Not retryable — the fixes are to run the mode on a Claude Code host, or to open a PR and use PR mode.

In PR mode on such a host, Phase 1 runs. Codex creates real child threads, and /specialist-review (row 4) is published there, so at M size one reviewer is available and the existing at-least-one rule carries the run into Phase 2. The Claude-only and third-party rows are logged as unavailable, exactly as they are on a Claude host that lacks them. Phase 1 and 2 are still skipped on the same three conditions as anywhere else — external_only == true, EFFECTIVE_SIZE == S, or every selected reviewer turning out unavailable. Nothing here loosens the Size S rule; external remains the way to state that intent rather than relying on the all-reviewers-unavailable degradation.

If MODE=uncommitted, skip Steps 2-5 below and Argument Parsing; jump directly to [Uncommitted Mode](#uncommitted-mode).

If MODE=post-commit, skip PR-mode pre-flight Step 2 below; do Argument Parsing (post-commit subsection) to resolve RANGE_SPEC, then jump to [Post-commit Mode](#post-commit-mode).

Step 2: PR mode pre-flight (MODE=pr only)

1. PR info already recorded in Step 1 (/tmp/gl-pr.json). Confirm state is OPEN; if not, stop.

1. Confirm working directory is clean:

``bash git status --porcelain `` If uncommitted changes exist, ask the user whether to commit first.

1. Record the PR number and repo owner/name (from gh repo view --json owner,name).

1. Read reviewer fallback config:

```bash # --- solopreneur config helpers (sourced from shared/config.sh) --- # One real shell file, so no harness rewrites the helpers on the way to the # shell. Claude Code replaces the ${CLAUDE_SKILL_DIR} token below when it loads # this body; Codex does not. It is SINGLE-quoted on purpose — it is a load-time # token, not an environment variable, and letting the shell expand the name # would source whatever an inherited value happened to point at. Unreplaced, it # is not a directory, so substitute the absolute path of the directory holding # THIS SKILL.md — every harness states that path to the model. SOLO_SKILL_DIR='${CLAUDE_SKILL_DIR}' [ -d "$SOLO_SKILL_DIR" ] || SOLO_SKILL_DIR="<absolute path of the directory holding this SKILL.md>" SOLO_CONFIG_SH="$SOLO_SKILL_DIR/../../shared/config.sh" # Three candidates, one contract. Inside the plugin the helpers sit at ../../shared/; # authoring against this repo reaches them under src/solopreneur/shared/; and a # skill republished on its own — any flattened skills directory — carries them # at scripts/config.sh instead, because shared/ is a sibling of skills/ and does # not travel with a per-skill copy. Try each in order, then STOP. Sourcing a # file that is not there does not halt the shell: every helper stays undefined, # every config read returns empty, and the 2026-08-11 A2 run showed where that # leads — the model "rescued" it with a repo-relative path, which resolves only # when the repo under review happens to be this plugin's own source repo. # Canonical authoring keeps non-skill source under src/.

GL_CFG=$(read_solopreneur_config greenlight) [ -z "$GL_CFG" ] && echo "NO_CONFIG" || echo "$GL_CFG"

# Objective verifier command for the inner verify loop (see "Inner verify # loop"). Empty when unconfigured → inner loop is skipped and the run is # flagged "no objective verifier configured for this loop". VERIFY_CMD=$(read_solopreneur_config verify | jq -r '.cmd // empty' 2>/dev/null) [ -z "$VERIFY_CMD" ] && echo "NO_VERIFIER" || echo "VERIFY_CMD=$VERIFY_CMD" `` If config exists, read fallback_order from the greenlight key. If absent (NO_CONFIG`), use default: codex-bot as starting reviewer, ask user on failure.

Step 3: Codex CLI availability (both modes)

command -v codex &>/dev/null && echo "CODEX_INSTALLED=true" || echo "CODEX_INSTALLED=false"
codex login status 2>/dev/null && echo "CODEX_AUTH=true" || echo "CODEX_AUTH=false"

• PR mode: Best-effort hint. Used later by Argument Parsing to gate codex cli reviewer selection.
• Uncommitted mode: Required. If CODEX_INSTALLED=false or CODEX_AUTH=false, stop with install instructions:
• Not installed → npm install -g @openai/codex
• Not authenticated → codex login

Argument Parsing

⏭️ Skip this section entirely if `MODE=uncommitted` — jump to Uncommitted Mode.

Post-commit mode parsing (MODE=post-commit only)

raw_args = args ?? ""
spec = raw_args after "post-commit" keyword (trimmed) — empty if keyword absent
 
if spec is empty:
  → ask user to provide a SHA or range (e.g., "/greenlight post-commit <SHA>")
elif spec matches a single SHA (verify with `git rev-parse --verify <SHA>^{commit}`):
  RANGE_SPEC = single, BASE_SHA = "<SHA>^", TIP_SHA = "<SHA>"
elif spec matches "<FROM>..<TO>" (verify both SHAs exist):
  # Follow standard git revision-range semantics: FROM is exclusive, TO is inclusive.
  # `git diff <FROM>..<TO>` shows changes between FROM's tree and TO's tree, which
  # equals the cumulative effect of commits (FROM, TO]. Do NOT use "<FROM>^" — that
  # would include FROM itself, contradicting the `..` convention the user typed.
  RANGE_SPEC = range,  BASE_SHA = "<FROM>", TIP_SHA = "<TO>"
else:
  → tell user spec is invalid, stop
 
# Invariant: TIP_SHA must equal HEAD.
# Reviewing a historical range (TIP_SHA < HEAD) would let downstream tools leak
# past the user's intended tip: `codex review --base BASE` reviews BASE..HEAD
# (not BASE..TIP), and the per-round `TIP_SHA = HEAD` advance in Phase 3 would
# sweep in unrelated intermediate commits on subsequent rounds. Rather than
# silently expanding scope, reject historical ranges up front.
if `git rev-parse <TIP_SHA>` != `git rev-parse HEAD`:
  → stop with: "Post-commit mode requires TIP_SHA == HEAD. Got TIP=<short-SHA>,
     HEAD=<short-SHA>. For historical-only review of a single commit, invoke per-commit
     instead: `codex review --commit <SHA>`."
 
# Invariant: origin/main must be reachable from HEAD (local main not behind origin).
# Post-commit mode's contract is "review committed work" — push state is not part
# of the contract. Local-only commits (HEAD ahead of origin/main) are allowed: the
# review loop's fix-on-top push will publish them together with the fix commits,
# which is the expected "review then land" flow.
# What we MUST prevent is a stale local main (HEAD behind origin/main): the
# per-round fix-on-top push would be rejected as non-fast-forward, breaking the loop.
# `git merge-base --is-ancestor origin/main HEAD` returns true iff origin/main is
# reachable from HEAD — which holds when HEAD == origin/main OR HEAD is ahead of
# origin/main, but fails when HEAD is behind. Exactly the condition we want.
git fetch origin main
if ! git merge-base --is-ancestor origin/main HEAD:
  → stop with: "Post-commit mode requires local main to not be behind origin/main
     (origin/main must be reachable from HEAD). Got HEAD=<short-SHA>,
     origin/main=<short-SHA>. Pull/rebase first, then re-invoke."
 
# Invariant: BASE_SHA must be reachable from origin/main.
# When HEAD is ahead of origin/main, the fix-on-top push at end-of-loop will
# publish everything in (origin/main, HEAD]. If RANGE_SPEC starts past
# origin/main (BASE_SHA itself local-only), commits in (origin/main, BASE_SHA]
# would be pushed without ever being reviewed. Require BASE_SHA to be on or
# before origin/main so the reviewed range (BASE_SHA, HEAD] covers every
# local-only commit on the branch.
if ! git merge-base --is-ancestor <BASE_SHA> origin/main:
  → stop with: "BASE_SHA must be reachable from origin/main — the reviewed
     range must cover all local-only commits, otherwise unreviewed commits
     would be pushed by the fix-on-top loop. Got BASE=<short-SHA>, which is
     itself local-only. Either widen the range to start at or before
     origin/main, or push existing local commits first."

These invariant guards — and the per-round re-checks in Phase 3 (Step 1's branch /

BASE / TIP checks and the push-verification gates) — are **halt /

invariant-violation** in the

Escalation taxonomy: a hard stop the

orchestrator must not retry (attended: surface the error and ask the user).

After resolving, jump to [Post-commit Mode](#post-commit-mode) — skip the PR mode parsing block below.

PR mode parsing (MODE=pr only)

# Parse external mode and reviewer from args

size_arg      = value of a token matching (case-insensitive) "size=<s|m|l>", else ""
                (a malformed size=… value is ignored — treated as "")

                tokens dropped, rejoined + trimmed
current_reviewer = reviewer_args non-empty ? reviewer_args : "codex bot"
 
# The two selection tokens are handed straight to `resolve` (see Reviewer
# selection). Both are validated there, and a stale one degrades with a warning

# ago, and a stale token must not turn an unattended run into an empty one.
SELECTED_RECIPES = select_arg
 
# `unattended` (set by todos-babysit auto mode / autopilot dispatch): every
# "ask the user" branch in Reviewer selection / Fallback Logic below becomes
# "log the reason and exit non-zero" — never block on input.
 
# Codex CLI availability gate: if user specified codex cli but CLI unavailable, fall back
if current_reviewer == "codex cli" and pre-flight detected CLI not installed or not authenticated:
  → notify user:
    - not installed: "Codex CLI not installed, switching to Codex GitHub bot. To install: npm install -g @openai/codex && codex login"
    - not authenticated: "Codex CLI not authenticated, switching to Codex GitHub bot. Run: !codex login"
  → current_reviewer = "codex bot"
 
# Derived LAST, after the CLI gate above may have rewritten current_reviewer —
# deriving it earlier would carry `codex-cli` into the gate on a machine where
# the CLI just failed its availability check.
#
# A positional reviewer alias has always meant "this is the reviewer whose
# verdict ends the loop", which is exactly what a gate is — so it feeds
# GATE_RECIPE. Map the alias through the registry's `aliases (arg)` column to a
# recipe_id; `resolve` compares on ids, so passing the alias spelling straight
# through would match nothing.
#
# Left EMPTY when the caller named nobody. The "codex bot" default above exists
# so the old single-reviewer prose has something to say; passing it as a gate
# would let it silently outrank a configured fallback_order on every plain
# `/greenlight` run.
GATE_RECIPE = gate_arg non-empty ? gate_arg
            : (reviewer_args non-empty ? <recipe_id of current_reviewer> : "")
 
# Effective size (see Sizing). Run the cascade over the PR diff and take the

#   → EFFECTIVE_SIZE ∈ {S,M,L}, SIZE_MAX_ROUNDS ∈ {3,5,10}
# If COMPUTED_SIZE=S and size_arg is empty, record the "auto-sized S — verify" flag.

If `external_only == true` OR `EFFECTIVE_SIZE == S`, skip Phase 1 and Phase 2, jump directly to Phase 3 (size S reviews externally only — see Sizing).

Uncommitted Mode

Only runs when `MODE=uncommitted` from Pre-flight Step 1. PR mode skips this section entirely.

Codex CLI --uncommitted review loop. Fixes in-place, does NOT commit. User reviews and commits manually afterwards.

Loop

round = 0
LOOP (max 10 rounds):
  round += 1
 
  1. Verify still on main with uncommitted changes:
     ```bash
     git branch --show-current  # must be main
     git status --porcelain     # must be non-empty
     ```
     If either changed (e.g., user switched branch or committed mid-loop) → stop and tell user.
 
  2. Run codex CLI:
     ```bash
     codex review --uncommitted -c 'model_reasoning_effort="high"' --enable web_search_cached 2>&1
     ```
     Capture full stdout/stderr. Timeout: 5 min.
 
  3. Parse output:
     - No `[P*]` tags (only summary paragraphs like "looks good" / "no issues") → **clean pass, exit loop**
     - Has `[P*]` tags → extract findings (file, line, priority, description, suggested fix)
     - **Non-zero exit** → stop, tell user codex CLI unavailable, preserve working
       tree. Search the output for "usage limit" / "rate limit" only to name the
       reason for the human, and **only once the exit status is already non-zero**
       — never as the test itself. Capturing `2>&1` merges the reviewer's own prose
       into the text being searched, and a reviewer that quotes those words while
       exiting 0 and returning a verdict is not rate-limited: on 2026-08-11 that
       false positive fired on a `codex review` that had answered normally, because
       it had read a document containing the phrase. A CLI that really is limited
       returns no `[P*]` and no clean sentence, which the rules above already
       classify as unresponsive.
 
  4. Dispatch fix subagent — see Step 4 below.
 
  5. After subagent returns, verify working tree still has uncommitted changes (subagent might have accidentally committed).
     If working tree is clean but commits were added → stop and tell user (violates no-commit invariant).
 
  6. Back to step 1 (next round). Pass prior-round findings to next subagent for push-back awareness.
 
End: max 10 rounds reached → stop and report to user.

Step 4: Fix subagent (per round)

Dispatch subagent with these explicit instructions. Use Agent tool, general-purpose type.

Agent(
  description: "Fix codex uncommitted review findings (round N)",
  prompt: <see below>
)

Prompt must contain:

1. Context: "You are in uncommitted mode. All changes live in the working tree on the main branch. Your job is to address codex review findings by editing files directly."

1. Findings list (full stdout from codex, or parsed list with file + line + priority + description + suggested fix).

1. Prior push-backs (if round > 1): list of findings from earlier rounds that were pushed back with reasoning. Subagent should reconsider before pushing back again.

1. Evaluation framework: "Invoke superpowers:receiving-code-review skill first to load the review-receiving mindset. If unavailable, evaluate each finding: fix genuine issues, push back on false positives with solid technical reasoning."

1. Hard constraints:

• Do NOT run `git commit`, `git push`, `git add && commit`, or any commit operation.
• Do NOT create branches, worktrees, or PRs.
• Edit source files directly. Leave all changes uncommitted.
• If you want to push back on a finding, write reasoning in your final report — do not add code comments explaining the push-back (keeps the diff clean).

1. Return format: report what was fixed (file + line + fix summary) and what was pushed back (finding + reasoning).

Exit Conditions

1. Clean pass: codex stdout has no [P*] tags → report rounds run, items fixed, items pushed back.
2. Push-back exit: all findings this round were already pushed back in prior rounds with the same reasoning → report and exit.
3. Max 10 rounds: stop and report last round's findings; let user decide.
4. Aborted invariants: branch changed / commits appeared / codex CLI unavailable → stop with specific reason.

Final report (on any exit)

Uncommitted review loop complete.
- Exit reason: <clean pass / push-back / max rounds / aborted>
- Rounds run: <N>
- Items fixed: <M>
- Items pushed back: <K>
- Working tree: has uncommitted changes (run `git diff` to review, then commit manually)

Do not offer to commit or push. User's CLAUDE.md rule on product repo main branch: wait for explicit user instruction.

Post-commit Mode

Only runs when `MODE=post-commit` from Pre-flight Step 1, which requires the

explicit /greenlight post-commit <SHA> argument (no auto-detect). PR mode and

Uncommitted mode skip this section entirely.

Reviews committed work on main (pushed or local-only) when no open PR exists. Runs Phase 1 internal subagents + Codex CLI + agy in parallel. Skips PR-bound reviewers (Codex GitHub bot, Gemini Code Assist bot, CodeRabbit) since they require an open PR. agy is the Gemini-family CLI reviewer here — pinning it to a Gemini model keeps model diversity against the Claude main loop and the GPT-family Codex.

Fixes are committed as new commits on top — no git commit --amend. Reasons: keeps the loop logic uniform whether or not the original commits were already pushed (amend would require force-push for pushed commits, violating the "no rewriting shared history" rule); preserves the original commit boundary; lets each review round produce a clearly attributable fix commit.

Convention: the bash snippets in this section are illustrative pseudo-code,

not literal runnable scripts. The orchestrating agent translates them before

execution: substitute <PLACEHOLDERS> with concrete values, replace prose

directives like stop with: "..." with valid bash (e.g. echo "..."; exit 1),

and ensure heredoc terminators (EOF) start at column 1 (or use <<- with tabs).

Snippets prioritize readability over runnability.

Range resolution (recap)

RANGE_SPEC, BASE_SHA, and TIP_SHA were resolved during Argument Parsing. The diff command depends on shape:

Range semantics: BASE_SHA is exclusive and TIP_SHA is inclusive — i.e. the review covers commits (BASE_SHA, TIP_SHA]. This matches standard git .. convention.

Invariant: `TIP_SHA == HEAD`. Enforced during Argument Parsing — historical ranges (TIP < HEAD) are rejected with a clear error. This keeps codex review --base BASE (which reviews to current HEAD) equivalent to BASE..TIP_SHA, and prevents the per-round TIP_SHA = HEAD advance from sweeping in unrelated intermediate commits.

Resolve the verify command (once, before any fix dispatch)

Post-commit mode skips PR-mode Pre-flight Step 2, so VERIFY_CMD is not resolved by that path. Resolve it here instead — once, before Phase 2 (the first fix dispatch) — exactly as Resolving the verify command prescribes: source the config helpers (the marker block from Pre-flight Step 2, copied as-is), then in the same bash block:

VERIFY_CMD=$(read_solopreneur_config verify | jq -r '.cmd // empty' 2>/dev/null)
[ -z "$VERIFY_CMD" ] && echo "NO_VERIFIER" || echo "VERIFY_CMD=$VERIFY_CMD"

Without this step both post-commit fix dispatches (Phase 2 and Phase 3 Step 5) would read an unset VERIFY_CMD and silently skip the inner verify loop — the mode would never gate a fix, defeating this PR's purpose. On NO_VERIFIER, skip the inner loop in both dispatches and add the "no objective verifier configured for this loop" flag to the final report.

Resolve the effective size (once, before Phase 1)

Post-commit mode is sized too (only Uncommitted mode is exempt). Compute it once, before Phase 1, exactly as Sizing prescribes — run the cascade with DIFF_RANGE set to the resolved review range and no size= token (post-commit ignores non-post-commit args, so SIZE_ARG is empty and EFFECTIVE_SIZE = COMPUTED_SIZE):

# Single commit → "<TIP_SHA>^..<TIP_SHA>"; range → "<BASE_SHA>..<TIP_SHA>" (two-dot).
if [ "$RANGE_SPEC" = single ]; then DIFF_RANGE="${TIP_SHA}^..${TIP_SHA}"; else DIFF_RANGE="${BASE_SHA}..${TIP_SHA}"; fi
SIZE_ARG=""   # post-commit takes no size= token
# ... then run the Sizing "Mechanical cascade" + "Size override & freshness"
#     snippets → EFFECTIVE_SIZE, SIZE_MAX_ROUNDS.

EFFECTIVE_SIZE then gates Phase 1 reviewer selection, the verification gate, and the Phase 3 SIZE_MAX_ROUNDS loop bound below — the same profile PR mode uses. Because there is no override token, an S here is always auto-classified, so it records the "auto-sized S — verify" flag.

Phase 1: Internal Review (post-commit variant)

Same as PR mode Phase 1, including the `EFFECTIVE_SIZE` gate (Sizing): at S skip Phase 1 (and Phase 2) entirely and go straight to Phase 3; at M run only /specialist-review + ponytail:ponytail-review; at L run all 5. Dispatch the selected subagents in parallel, report-only — but the diff range is RANGE_SPEC instead of main...HEAD. Each subagent prompt must include the actual diff content (output of the diff command above), not the raw shell expression. Subagents are still report-only.

After all subagents return, consolidate findings (merge + dedupe) → PHASE1_FINDINGS (at size S there are none — skip to Phase 3).

Verification gate (optional). At effective size L with the Workflow tool

available (S and M skip it), run the adversarial verification gate on

PHASE1_FINDINGS before Phase 2 — see Verification gate and

references/adversarial-verify.md.

Pass PHASE1_FINDINGS as findings and the resolved range diff command from the

Range resolution table as diff_cmd. Replace

PHASE1_FINDINGS with the confirmed (survivor) list; record rejected

findings as pushed back. If every finding is rejected, PHASE1_FINDINGS is now

empty — follow the existing empty path (skip Phase 2, go to Phase 3). Tool

unavailable → skip the gate; PHASE1_FINDINGS is unchanged.

Phase 2: Initial fix (Phase 1 findings only)

If PHASE1_FINDINGS is non-empty, dispatch a fix subagent with the same evaluation framework as Uncommitted Mode (superpowers:receiving-code-review first), but with post-commit hard constraints:

• Edit source files directly.
• Inner verify loop (when VERIFY_CMD is set): after editing, run VERIFY_CMD

against the working tree before the commit below; commit only on a green verify; on the 3rd failure return a structured halt (no commit/push). Include the anti-gaming guard. See Inner verify loop.

• After edits, run `git add` + `git commit` + `git push`. Commit message:

fix: post-commit review fixes (Phase 1) — <summary>.

• Do NOT use `git commit --amend`. Always fix as new commits on top — see

rationale at the top of Post-commit Mode.

• Do NOT create a new PR or branch.

Halt check (before the push verification below). If the fix subagent returned a structured halt (inner-verify failure or anti-gaming catch) it made no commit — stop at the blocked exit and reference the halts/ payload. Do NOT fall through to the push verification below: a halt leaves HEAD == origin/main, which would false-pass its HEAD != origin/main check and mask the failure.

After push, verify the push actually landed on `origin/main` before advancing `TIP_SHA` — same hard gate as Phase 3 Step 6. If the fix subagent's push was rejected or skipped, Phase 3 would otherwise enter the loop reviewing local-only commits:

git fetch origin main
LOCAL_HEAD=$(git rev-parse HEAD)
REMOTE_HEAD=$(git rev-parse origin/main)
if [ "$LOCAL_HEAD" != "$REMOTE_HEAD" ]; then
  stop with: "Phase 2 push verification failed — HEAD ($LOCAL_HEAD) does not
  match origin/main ($REMOTE_HEAD). The fix subagent's push was rejected or
  skipped. Investigate before continuing."
fi

Push confirmed. Advance TIP_SHA = HEAD. If RANGE_SPEC = single, also set RANGE_SPEC = range (keep BASE_SHA unchanged) so subsequent rounds review the full cumulative range (BASE_SHA..HEAD) — not just the latest fix commit, which would forget the original commit under review.

If PHASE1_FINDINGS is empty, skip Phase 2 and proceed straight to Phase 3.

Phase 3: External CLI loop

Codex CLI and agy run in parallel each round; results are merged + deduped; fixes commit on top; repeat.

grok-cli is not part of this post-commit pair — adding it here would

change the default cost of every post-commit run. Post-commit support for

grok-cli is a follow-up; today it is a PR-mode reviewer only (Flow B),

where it runs on explicit request.

agy availability gate (mirrors the Codex CLI gate). agy has no login status subcommand, so probe headless output once before the loop — one trivial call proves installed AND authenticated AND that non-TTY stdout is not being dropped:

AGY_AVAILABLE=false
if command -v agy &>/dev/null; then
  # Unauthenticated agy prints a Google authorization URL instead of a result.
  # No --dangerously-skip-permissions: this probe (and the review call below) is
  # text-only and needs no tools; see the review-dispatch note for why bypassing
  # tool permissions is unsafe here.
  AGY_PROBE=$(agy --print "reply with the single word READY" 2>&1)
  if printf '%s' "$AGY_PROBE" | grep -q "READY" \
     && ! printf '%s' "$AGY_PROBE" | grep -qiE "https?://[^ ]*(auth|login|oauth|accounts\.google)"; then
    AGY_AVAILABLE=true
  fi
  # else: not authenticated (auth URL), empty output (non-TTY drop), or errored.
fi

If AGY_AVAILABLE=false, skip the agy dispatch each round and run Codex CLI only. If Codex CLI is also unavailable, the existing "both CLIs fail → stop" path fires.

round = 0
LOOP (max SIZE_MAX_ROUNDS rounds — S 3 / M 5 / L 10; see Sizing):
  round += 1
 
  1. Verify still on main, BASE_SHA is reachable from HEAD, and TIP_SHA == HEAD:
     ```bash
     git branch --show-current  # must be main
     git merge-base --is-ancestor <BASE_SHA> HEAD || echo "BASE not reachable"
     [ "$(git rev-parse <TIP_SHA>)" = "$(git rev-parse HEAD)" ] || echo "TIP != HEAD"
     ```
     If branch changed, BASE unreachable, or TIP != HEAD → stop and tell user.
     (TIP == HEAD is the invariant set during Argument Parsing and re-asserted
     each round after the fix-commit advance — see Step 6.)
 
  2. Dispatch the external reviewers. **At `EFFECTIVE_SIZE` M or L**, run Codex CLI
     and agy (when `AGY_AVAILABLE=true`) **in parallel** (parallel Bash tool calls,
     or `&`-backgrounded shell — never sequential). **At `EFFECTIVE_SIZE` S**, run
     only the **single preferred available** external reviewer — Codex CLI when
     available, else agy — never both: the S profile is one reviewer (see
     [Sizing](#sizing-sml-risk-profile)), and the parallel pair is exactly the
     doubled cost S removes. The steps below are written for the full pair; at S,
     skip whichever reviewer is not the chosen one.
 
     **Codex CLI:**
     ```bash
     # Single commit:
     codex review --commit <TIP_SHA> -c 'model_reasoning_effort="high"' 2>&1
     # Range (BASE_SHA..TIP_SHA):
     codex review --base <BASE_SHA> -c 'model_reasoning_effort="high"' 2>&1
     ```
     Capture stdout. Parse `[P*]` tags.
 
     > Under the `TIP_SHA == HEAD` invariant, `codex review --base <BASE_SHA>` is
     > equivalent to reviewing `<BASE_SHA>..<TIP_SHA>`. (Historical ranges where
     > `<TIP_SHA>` ≠ HEAD are rejected during Argument Parsing.)
 
     **agy (Gemini-family CLI):**
     ```bash
     # Capture the diff first — see "Range resolution" table above for the exact
     # diff command to use. Use `git log -p <BASE>..<TIP>` form (or `git show` for
     # single) so per-commit context (subject, author, message) is preserved.
     # Substitute <RANGE_SPEC>, <TIP_SHA>, <BASE_SHA> with their resolved values
     # from the Range resolution step before running.
     if [ "<RANGE_SPEC>" = "single" ]; then
       DIFF_CONTENT=$(git show "<TIP_SHA>")
     else
       DIFF_CONTENT=$(git log -p "<BASE_SHA>..<TIP_SHA>")
     fi
     # agy `--print` (headless) does NOT read stdin — the whole diff rides in a
     # single --print argument. That exposes two failure modes, guarded below.
     #
     # (1) argv size: argv+env is bounded by SC_ARG_MAX, so a large diff can fail
     #     agy before it starts. Codex CLI in this same loop reviews via `--base`
     #     with no such limit, so on an oversized diff degrade only the agy branch.
     AGY_MAX_DIFF_BYTES=100000   # conservative; well under a 256KB+ ARG_MAX with env headroom
     if [ "$(printf '%s' "$DIFF_CONTENT" | wc -c)" -gt "$AGY_MAX_DIFF_BYTES" ]; then
       echo "diff too large for agy argv (> $AGY_MAX_DIFF_BYTES B) — Codex CLI only this round"
       AGY_OUT=""
     else
       # (2) marker false-match: a per-invocation nonce, so the completion marker
       #     cannot pre-exist in the reviewed diff (this skill file literally
       #     contains a marker string) and satisfy the check below by accident.
       AGY_MARKER="AGY-DONE-$(date +%s)-$$"

       # instructions is the dangerous combination. Headless --print still answers
       # under default permissions (verified). Unquoted heredoc so $DIFF_CONTENT

         AGY_OUT=""
       fi
     fi
     ```
     Parse `$AGY_OUT` for `[P*]` lines (ignore the marker line). agy may reply in a
     non-English language — key off the `[P*]` tags and the marker, not the English
     "No issues found." string.
 
     If either CLI fails — **non-zero exit**, or, for agy, empty/markerless output
     — proceed with whichever succeeded. If both fail → stop, tell user, preserve
     commits. As in uncommitted mode, a "usage limit" / "rate limit" match names
     the failure **after** a non-zero exit; it never decides one on its own,
     because the captured text includes the reviewer's own prose.
 
  3. Merge findings (`MERGED_FINDINGS`):
     - For each Codex finding (file, line, topic), check if an agy finding overlaps:
       same file, line within ±5, topic semantically similar → keep one (prefer the
       more specific description).
     - Result: deduped list of findings from both reviewers.
 
  3b. VERIFICATION GATE (optional): at effective size L with the Workflow tool
     available (S and M skip it), challenge MERGED_FINDINGS with the adversarial gate
     before Step 4 (see the "Verification gate" section and
     references/adversarial-verify.md). Pass MERGED_FINDINGS as
     `findings` and this round's diff command (Range resolution table) as `diff_cmd`.
     Replace MERGED_FINDINGS with the confirmed survivors; record rejected findings
     as pushed back and carry their reasoning into prior-push-back context. If every
     finding is rejected, MERGED_FINDINGS is empty and Step 4 treats it as a
     push-back exit (findings existed but were all rejected), NOT a clean pass. Tool
     unavailable → skip the gate; MERGED_FINDINGS unchanged.
 
  4. Parse `MERGED_FINDINGS`:
     - Empty because reviewers raised nothing this round → **clean pass, exit loop.**
     - Empty because the verification gate (3b) rejected every finding this round →
       **push-back exit, exit loop** (findings existed but were all refuted — not a
       clean pass).
     - All findings repeat prior rounds with the same reasoning already pushed back
       → **push-back exit, exit loop.**
     - Otherwise → continue to Step 5.
 
  5. Dispatch fix subagent with `MERGED_FINDINGS` and prior-round push-backs.
     Hard constraints (same as Phase 2):
     - Invoke `superpowers:receiving-code-review` first to evaluate findings.
     - Edit source files directly.
     - **Inner verify loop** (when `VERIFY_CMD` is set): after editing, run
       `VERIFY_CMD` against the working tree **before the commit below**; commit
       only on a green verify; on the 3rd failure return a structured halt (no
       commit/push). Include the anti-gaming guard. See
       [Inner verify loop](#inner-verify-loop-objective-verifier-gate).
     - **After edits: `git add` + `git commit` + `git push`.** Commit message:
       `fix: post-commit review fixes (round <N>) — <summary>`.
     - **Do NOT amend. Do NOT create branch or PR.**
 
  5b. Halt check: if the fix subagent returned a structured halt (no commit), stop
     at the blocked exit and reference the `halts/` payload — do NOT run Step 6's
     push gate (a halt leaves `HEAD == origin/main`, which would false-pass it) and
     do NOT loop to the next round.
 
  6. Hard gate: verify the fix subagent's push actually landed on `origin/main`.
     If `HEAD != origin/main` (push rejected, skipped, or never happened), stop —
     do NOT advance `TIP_SHA` and do NOT loop, otherwise the next round would
     review unpushed local state and the final report would falsely claim the
     commit was pushed:
     ```bash
     git fetch origin main
     LOCAL_HEAD=$(git rev-parse HEAD)
     REMOTE_HEAD=$(git rev-parse origin/main)
     if [ "$LOCAL_HEAD" != "$REMOTE_HEAD" ]; then
       stop with: "Push verification failed — HEAD ($LOCAL_HEAD) does not match
       origin/main ($REMOTE_HEAD). The fix subagent's push was rejected or skipped.
       Investigate before continuing."
     fi
     ```
     Push confirmed. Update `TIP_SHA = HEAD`. If `RANGE_SPEC = single`, also set
     `RANGE_SPEC = range` (keep `BASE_SHA` unchanged) so subsequent rounds review
     the full cumulative range (`BASE_SHA..HEAD`) — not just the latest fix commit.
     Loop back to Step 1.
 
End: max SIZE_MAX_ROUNDS rounds (S 3 / M 5 / L 10) → stop and report last round's findings; let user decide.

Exit Conditions

1. Clean pass: Codex CLI reports no [P*] findings, and agy either was

unavailable/failed this round or also reports none → done. (When agy is down the round runs Codex CLI only, so Codex's clean result alone is the pass — don't wait on a reviewer that didn't run.)

1. Push-back exit: all findings repeat prior rounds with the same reasoning → done.
2. Max `SIZE_MAX_ROUNDS` rounds — S 3 / M 5 / L 10 by effective size (see

Sizing); the M default of 5 matches this mode's prior fixed cap and stays lower than Uncommitted Mode's 10, since post-commit is a follow-up review stage, not fresh implementation: stop and report last round; user decides.

1. Aborted invariants: branch changed, BASE unreachable, both CLIs unavailable →

stop with specific reason.

Pre-exit push (clean pass / push-back / max rounds)

If the loop exits without ever entering a fix step (Phase 1 clean + Phase 3 round 1 clean), HEAD may still be ahead of origin/main with the reviewed local-only commits unpushed — fix subagents handle their own push, but a zero-finding fast path bypasses them entirely. Without this step, the final report's Last commit pushed claim would be false:

git fetch origin main
if [ "$(git rev-parse HEAD)" != "$(git rev-parse origin/main)" ]; then
  git push origin main
  git fetch origin main
  if [ "$(git rev-parse HEAD)" != "$(git rev-parse origin/main)" ]; then
    stop with: "Pre-exit push failed — HEAD still does not match origin/main
    after push. Investigate before reporting completion."
  fi
fi

Skip for the Aborted invariants exit — that path indicates the loop is in a bad state, don't publish anything.

Final report (on any exit)

Post-commit review loop complete.
- Range: <RANGE_SPEC>
- Exit reason: <clean pass / push-back / max rounds / aborted / halt>
- Rounds run: <N>
- Items fixed: <M>  (across <K> new commits on top)
- Items pushed back: <P>
- Last commit pushed: <SHA>

Then append the Flags section (Inner verify loop → Flags) if anything flagged this run — including "no objective verifier configured for this loop"; omit it otherwise. On a halt, report blocked and reference the halts/ payload path.

Do not offer to amend or open a PR. Fixes live as new commits on main.

Phase 1: Internal Review

⏭️ Skip entirely if `MODE=uncommitted`.

⏭️ If `external_only == true` OR `EFFECTIVE_SIZE == S`, skip this phase — go to [Phase 3](#phase-3-external-review-loop). (Size S reviews externally only; see Sizing.)

Which reviewers run depends on `EFFECTIVE_SIZE` (see [Sizing](#sizing-sml-risk-profile)):

• M (default) → dispatch only rows 4 and 5 below (/specialist-review + ponytail:ponytail-review).
• L → dispatch all 5 rows below.
• S → Phase 1 is skipped entirely (handled by the skip above).

Dispatch the selected subagents in parallel (`run_in_background: true`), each running a review skill. All report-only — no code changes.

On Codex, ignore run_in_background — it is a Claude Code parameter. Run the selected reviewer skills however that host runs work: in this thread, or one spawn_agent child per reviewer. At M size /specialist-review is usually the only row that resolves there, so there is nothing to parallelise either way, and the review reaches a child thread regardless because that skill spawns its own per-stack reviewers. The rows that do not resolve still get their unavailable line — skipping the attempt does not skip the report.

All skills are optional. If any subagent fails (skill not found, invocation error, or subagent error), log which skill was unavailable and why, skip that subagent, and continue waiting for others. For external plugins (e.g. ponytail), print a one-line install suggestion when unavailable. A row you never attempt counts as unavailable and gets the same line. Every row this size selected ends up reported either as run or as skipped-with-reason; a Phase 1 report that names only the reviewers that ran is indistinguishable from one where the others were never selected.

• At least 1 subagent succeeds → proceed to Phase 2 (using completed reports)
• All fail → notify user "Phase 1: all internal reviewers unavailable", skip Phase 1 + 2, proceed to Phase 3

Each subagent prompt must include:

• PR diff (via git diff main...HEAD)
• Explicit instruction: "report-only mode, do not modify any files"
• Required format: each suggestion includes file path, line number, issue description, specific fix suggestion (with proposed code)

Wait for all successful subagents to report, then proceed to Phase 2.

Phase 2: Consolidate + Fix

⏭️ Skip entirely if `MODE=uncommitted`.

⏭️ If `external_only == true` OR `EFFECTIVE_SIZE == S`, skip this phase — go to [Phase 3](#phase-3-external-review-loop).

2a. Consolidate reports

After receiving all successful reports:

1. Merge and deduplicate: same suggestion for the same file and line → keep only one
2. Group by file: list all suggestions organized by file
3. Handle contradictions: when suggestions contradict each other, apply the

Findings-contradiction handling table. Unattended runs follow the table (no prompt); attended runs surface it inline and keep asking the user — the decision-point-flag attended projection.

Verification gate (optional). At effective size L with the Workflow tool

available (S and M skip it), run the adversarial verification gate on the

consolidated suggestion list before dispatching 2b — see

Verification gate and

references/adversarial-verify.md. Pass the deduped suggestions as findings

and git diff main...HEAD as diff_cmd. Dispatch 2b with only the **confirmed

(survivor) findings; record each rejected** finding as pushed back (with the

skeptics' reasoning). If every finding is rejected, **skip 2b and proceed to

Phase 3**. Tool unavailable → skip the gate, pass the full list to 2b.

2b. Dispatch fix subagent

Hand the consolidated suggestion list to a subagent. The prompt must include:

• Full content of all suggestions (file, line, issue description, proposed fix)
• Instruction: "Use the superpowers:receiving-code-review skill framework to evaluate each suggestion"
• Instruction: "False positives require solid technical reasoning to push back"
• Instruction: "After fixes, commit + push"
• Inner verify loop (when VERIFY_CMD is set): run VERIFY_CMD against the

working tree before committing; commit only on a green verify; on the 3rd failure return a structured halt (no commit). Include the anti-gaming guard. See Inner verify loop.

• Commit message format: fix: internal review fixes — <summary>

Agent(
  description: "Process internal review feedback",
  prompt: "Here are the consolidated suggestions from internal reviewers:\n\n<SUGGESTIONS>\n\nInvoke the superpowers:receiving-code-review skill first, use its framework to evaluate each one, fix items worth fixing. If a VERIFY_CMD was provided, follow the Inner verify loop: run it against the working tree before committing and commit only when it passes (3rd failure → structured halt, no commit). Then commit + push."
)

Halt check. If the subagent returned a structured halt (no commit), stop at the blocked exit and reference the halts/ payload — do NOT treat the absent commit as a clean push in 2c, and do NOT advance to Phase 3.

2c. Confirm push succeeded, then proceed to Phase 3.

Phase 3: External Review Loop

⏭️ Skip entirely if `MODE=uncommitted`.

Step 0: Read existing PR feedback

Before triggering any reviewer, fetch all existing review feedback on the PR:

gh api graphql -f query='query($owner:String!,$repo:String!,$pr:Int!){
  repository(owner:$owner,name:$repo){
    pullRequest(number:$pr){
      reviews(first:50){
        nodes{ author{ login } state body }
      }
      reviewThreads(first:100){
        nodes{
          isResolved
          comments(first:5){
            nodes{ author{ login } body path line }
          }
        }
      }
    }
  }
}' -f owner=OWNER -f repo=REPO -F pr=PR_NUMBER

Summarize results:

• Each reviewer's (human or bot) review status and suggestion count
• Number and source of unresolved threads

If there are unresolved threads: → Notify user: "PR has N unresolved review suggestions (from XXX)" → Ask: "Process this existing feedback first?"

• Yes → jump directly to Step 3 to process these threads
• No → continue triggering new review

If no unresolved threads: → Continue to main loop Step 1

Reviewer Registry

Single source of truth for every reviewer. Adding a reviewer is one row here and the matching row in `scripts/reviewer-registry.mjs` — nothing else downstream needs to change.

Reviewer kinds:

• github-bot — triggered by a PR comment and polled for. Whether it also

reviews automatically on push is observed, not declared — see auto in shared/config.md.

• local-cli — runs locally and is read from stdout. Availability comes from

a CLI gate, not from activity detection, because a local CLI never appears in GitHub data. It stays a legal PR-mode reviewer and gate.

Verified login is the App account a tool posts from. An App's bot login is app-scoped — identical on every repo — so a verified one is vendor knowledge. Only observed-and-verified logins are listed; guessing is unsafe (cursor[bot], cursor-com[bot] and bugbot[bot] are all real accounts, and GitHub Copilot posts as Copilot with no [bot] suffix). A — tool still works: detection collects it by type == "Bot", and an attended identify binds its login per repo (see Reviewer selection).

Family is the tool's upstream model family. A tool with no upstream model family of its own is keyed to its vendor instead — coderabbit and greptile to their own name, bugbot to cursor, the vendor that ships it. None of those is ever a host family, so none is ever filtered. See Host-family independence for what the column is for.

scripts/reviewer-registry.mjs is the executable copy of this table and the one the loop actually reads; tests/skill-sync.test.mjs fails CI when the two drift — on the trigger string and on the family cell.

Host-family independence

The gate must never be the host's own model family. The gate is the reviewer whose clean pass ends the loop, so a same-family gate is a model family approving its own work, and the loop terminates on it. Everything below follows from that one rule.

# Same detection as the sizing block and as `solopreneur_config_home`.
HOST_FAMILY=$([ -n "${CODEX_THREAD_ID:-}" ] && echo openai || echo anthropic)

• Only the gate is restricted. Non-gate reviewers are unrestricted — their

findings are advisory, so a same-family reviewer is still triggered and still collected. On a Codex host codex-cli stays a perfectly good ordinary reviewer; it just cannot be what closes the round.

• `resolve` enforces it, not this prose. --host-family is passed on every

invocation, and the script also derives the same value from the environment when the flag is missing — a forgotten flag must not be able to produce a same-family gate. Every gate path (explicit gate=, the fallback_order ladder, the EXHAUSTED_GATES advance, the seeded default) runs through the one canGate check, so there is no path around it.

• Observable: RESOLVED.gate.family and RESOLVED.hostFamily are printed.

They must never be equal.

• The independent gate for a Codex host is `claude-cli` (registry row above),

probed in pre-flight like codex-cli.

No qualifying independent gate → halt. When resolve returns gate: null with gateBlock: "host-family", every reviewer authorized here is the host's own family. Halt with reason_class: authority-boundary and report which family, plus the two fixes that actually work:

No independent gate: every authorized reviewer is <HOST_FAMILY>-family, the

same as this host, and a reviewer cannot gate its own family's work. Install

and authenticate a review CLI of another family (on a Codex host: claude),

or run this loop on a host of another family.

This is not the retryable exhaustion case. gateBlock: "unavailable" — an authorized independent reviewer exists but is down or absent — keeps reason_class: transient-dependency as before, because waiting can genuinely bring that reviewer back. Never fall back to a same-family clean pass, and never degrade to "no gate needed": with no gate there is no defensible clean signal.

In the steps below nothing re-derives a trigger string or a login from a name — both come from RESOLVED, built once by the detection block:

Deriving a login from a name is what the deleted hardcoded allowlist did, and it is why a newly installed reviewer used to be invisible.

Reviewer activity detection (pre-flight, PR mode)

Which reviewers to offer is decided by what actually reviews this repo, not a hardcoded list. Detection is an enhancement, never a gate — any failure falls straight through to the flow below.

Bot traces live in three places, and a bot may appear in only one, so all three are sampled. (Verified: on PR #108 the Gemini bot left ONLY a formal review — invisible to both comment endpoints.)

# Sample window — state it honestly to the user: the latest 100 comments from each
# of the two repo-level endpoints, plus formal reviews of the most-recent ~20 PRs.
# On a busy repo 100 comments can span only a few days — this is a RECENT-activity
# sample, not "all history".
DETECT_PR_SCAN=20   # most-recent PRs to scan for formal-review-only bots
 
# Emits raw "<login>\t<type>\t<iso>\t<source>" lines on stdout; returns NON-ZERO
# if ANY source errored. Detection is all-or-nothing: a partial sample (e.g.
# Source 3 fails while Source 1 works) would silently hide a bot that appears only
# in the missing source — exactly the formal-review-only case (PR #108's Gemini)
# that Source 3 exists to catch — so the caller degrades to `unavailable` rather
# than a truncated `ok`. Each source's error is captured via its own exit status,
# not swallowed. The constant 4th column is the evidence channel: `type == "Bot"`
# proves automation, not code review, so the reviewer test needs to know which
# endpoint a row came from.

RESOLVED is the loop's whole reviewer vocabulary from here on: Step 1 triggers trigger[], Step 2 waits on gate and harvests collect[], and the selection prompt below reads available[] / marked[]. Re-run `resolve` after any write that changes the answer — an identify, a retry, or adding agy / grok-cli — rather than patching RESOLVED by hand.

**Every later resolve call passes --fallback-order "$EFFECTIVE_FALLBACK_ORDER"

and --host-family "$HOST_FAMILY"** — the S-size narrowing below, the

post-write re-resolves, and the EXHAUSTED_GATES advance. Re-reading the raw

FALLBACK_ORDER on any of them would drop the appended entry mid-run and flip

a working Codex gate back to null.

Size S narrows the selection to one reviewer. An empty --select means "every reviewer that acts here", so on a repo with several detected bots (or an authed Codex CLI alongside them) an S run would trigger and collect all of them — several paid or slow reviews per round, which is the exact cost boundary S exists to draw. When EFFECTIVE_SIZE == S and a gate was resolved, re-run resolve once more with --select "$(jq -r '.gate.recipe' <<<"$RESOLVED")" so the round runs that reviewer alone. Sizes M and L keep the full set.

Skip the narrowing entirely when `.gate` is null — there is no reviewer to narrow to, and jq -r '.gate.recipe' on a null gate yields the string null, which resolve reads as a selection naming an unknown recipe. On a repo with nothing available that re-resolve overwrites a correct gateBlock: "host-family" with unavailable, routing a non-retryable authority-boundary halt as a retryable dependency failure. Keep the first result and take its halt path.

Interpret the result:

Detection only lists options — it never proves a bot is alive right now. A low-traffic repo's history always looks fresh, and during the Gemini sunset window a consumer repo's pre-7/17 activity will still be in-sample. Liveness is proven only by the trigger handshake and the post-trigger timeout (see the loop). First version shows `last_seen_in_sample` and makes no staleness judgment.

Codex CLI Availability Gate

Pre-flight detected Codex CLI installed and authenticated → available (best-effort hint, may still fail at runtime). Otherwise → unavailable. Don't list Codex CLI when asking user for fallback options.

Argument override for starting reviewer: User can specify starting reviewer at invocation:

• codex bot or no argument → start with Codex GitHub bot (default)
• codex cli → start with Codex CLI (must pass CLI gate; if fails, notify user and switch to codex bot)
• gemini → start with the Gemini bot (legal even post-sunset — see the sunset note under Fallback Logic)

Reviewer selection (PR mode)

The default is silence. When RESOLVED.gate is set, run with it — no prompt, however many reviewers act on this repo. RESOLVED.needsPrompt is true only when bots are known here but none can close a round: every one of them is unidentified, or marked unresponsive, and no local CLI is available.

Attended runs then ask one question, offering:

• Identify an unidentified bot. List every available entry with

recipe: null alongside its lastSeen; the user says which registry tool that login belongs to. Write it back, then re-run resolve:

```bash printf '{"observations":[{"login":"%s","recipe":"%s"}]}' "$LOGIN" "$RECIPE" \

```

• Retry a reviewer marked unresponsive. These are RESOLVED.marked — shown

with a "marked unresponsive" note, because the mark may date from a transient outage rather than a dead tool. Re-selecting clears it:

```bash printf '{"observations":[{"login":"%s","triggerable":true}]}' "$LOGIN" \

```

• Add `agy` to --cli-available for this run. Offered here and only here:

it is a local CLI that passes its gate whenever installed, but it is Gemini-family — switching model family is the user's call, not something a fallback chain should do silently. codex-cli needs no such prompt; it is the documented successor to codex-bot in the same family, and config.md's recommended fallback_order already pairs them.

• Add `grok-cli` to --cli-available for this run — the same opt-in rule as

agy, for the same reason. The add runs the detection block's grok-cli probe first and appends only when it passes — the same single probe definition the named paths (gate=/select=/alias/fallback_order) go through. Its lens is different from every other reviewer here: the bundled /code-review skill is a deliberately harsh maintainability audit (structural regressions, missed simplifications, file-size growth), so expect [P2] structural findings ordinary correctness reviewers skip. xai is never a host family, so once available it may also gate — on either host.

• Try a tool with no history here. GitHub exposes no way to ask which Apps a

repo has installed (/user/installations needs an App token, the per-repo endpoint needs an App JWT, and these reviewers create no check runs), so this is a question, not a lookup. The user picks a registry recipe and its trigger is posted this round — a trigger needs only the recipe string, never a login. A responder matching the registry's verified logins identifies itself; an unknown responder becomes an unidentified bot to identify next time; a silent window leaves no state behind, so retrying later costs one more answer and nothing else.

• Halt.

After any write, re-run resolve and continue with the new answer. Unattended runs never see this prompt — see the degradation rule under Fallback Logic.

Persisting an explicit gate. When the gate was named explicitly (a gate= token or a positional reviewer alias) and resolve accepted it without a degradation warning, remember it so later runs start there. Do not persist a gate that merely fell out of fallback_order (nothing was learned) or one that degraded (the choice was already stale).

Read the full five-layer subtree, move the gate to the front while keeping the rest of the order, and write the merged subtree back at the repo layer. Truncating to a single entry would disable the documented codex-bot → codex-cli succession; writing the whole merged object is what makes the repo layer's wholesale shadowing harmless, because the shadow then contains everything the five-layer read would have returned anyway:

CURRENT=$(read_solopreneur_config greenlight)
write_solopreneur_repo_config greenlight "$(jq -nc \
  --argjson cur "${CURRENT:-null}" --arg g "$GATE_RECIPE" \
  '($cur // {}) | .fallback_order = ([$g] + ((.fallback_order // []) - [$g]))')"

Because the persisted gate lands at the head of fallback_order, the next run's plain resolve picks it up without any gate= token — the prompt never returns for a repo that has a working gate.

Fallback Logic

The wizard presents the two reviewer kinds separately, and is entered only in the "without config" / exhausted paths below (never by an unattended caller — see below):

• GitHub bots — list the RESOLVED.available entries with kind: "bot",

each with its lastSeen. The Gemini bot therefore appears only on repos with recent Gemini activity. If detection was unavailable and the cache is empty, fall back to offering the default (Codex bot) and note it wasn't confirmed on this repo.

Every entry with `canGate: true` is selectable — dispatch reads its triggerText, handshake and poll from the registry row, so an identified coderabbit / bugbot / greptile is as drivable as codex-bot. Entries with canGate: false cannot close a round here and are shown informationally, their findings collected like any other unresolved thread. Two reasons, both real: an unidentified bot has no recipe, so there is no way to prompt it and therefore no way to know it has finished; and a reviewer of the host's own model family is barred from gating however well identified it is (see Host-family independence) — it is still triggered and still collected, just never as the gate.

• Local CLIs — offer Codex CLI when its gate passes (installed + authed). Never

hidden for lack of GitHub activity — local CLIs never appear in GitHub data.

With config (`${CLAUDE_CONFIG_DIR:-~/.claude}/solopreneur.json` has `greenlight` key): fallback_order orders gate candidates. The gate is the first entry that is both available and canGate; when it times out it is recorded triggerable: false and the next entry takes over, with a notification. Non-gate reviewers are untouched by this fallback — they were never holding the loop open, so a switch does not disturb what is being collected. Maintain the chosen gate for the rest of this cycle — no per-round reset. Re-run `resolve` on a switch rather than editing RESOLVED: the new gate brings its own poll and handshake, and a hand-patched login would poll one reviewer while triggering another.

Because config.md's recommended order is ["codex-bot", "codex-cli"], a dead Codex bot falls to Codex CLI automatically — same model family, no prompt.

Advancing past an exhausted gate. quota and timeout both mean "this gate cannot close the round", and both must exclude it before re-resolving. Simply re-running resolve does not advance: it is a pure function of the same inputs and returns the same gate. timeout at least writes triggerable: false, but quota writes nothing at all — so a quota'd gate would be re-triggered forever on a retry that deliberately does not count as a new round.

Keep an in-run EXHAUSTED_GATES list (recipe ids) and advance like this:

1. Add the exhausted gate's recipe to EXHAUSTED_GATES.
2. Next candidate = the first fallback_order entry that is available, canGate,

and not in EXHAUSTED_GATES. With no fallback_order configured, any available canGate entry not in EXHAUSTED_GATES.

1. When `select=` is active, candidates must come from inside that selection.

resolve resolves --gate within the selected subset, so naming a successor outside it is silently rejected and the ladder re-picks the reviewer just exhausted — the same infinite retry, reached through the selection path. A selection with no remaining candidate is exhaustion; never widen or drop select= to find one, which would run reviewers the caller excluded.

1. No candidate left → the ladder is exhausted (attended: the selection prompt;

unattended: halt with reason_class: transient-dependency).

1. Otherwise re-run resolve with --gate <next candidate> — naming it

explicitly is what makes the advance stick. Do not re-resolve with an empty --fallback-order hoping for a different answer: that puts resolve in its unconfigured branch, where it is free to pick the very gate just exhausted.

1. Exclude the exhausted reviewers from `--select` on that re-resolve, listing

the remaining selected recipe ids explicitly. EXHAUSTED_GATES is a loop-side list that resolve knows nothing about, so an exhausted reviewer stays in selected and trigger posts to it again — every successor attempt would re-trigger a reviewer that just answered "rate limited". This matters most for quota, which writes no persistent mark; a timeout is additionally excluded by the triggerable: false it records.

EXHAUSTED_GATES is per-run, not persisted: a quota window reopens on its own schedule, and marking a rate-limited reviewer permanently unusable in config would be exactly the stale-cache problem triggerable self-healing exists to avoid.

• If an entry names a github-bot that detection did not find, **warn before

triggering — do not hard-fail**: > "fallback_order lists gemini but no recent Gemini activity was detected on > this repo. Trying it anyway; on no response it will time out and fall through."

• When every gate candidate is exhausted — each tried and recorded

triggerable: false — or when RESOLVED.gate was null to begin with: attended run → the selection prompt; unattended run → halt with `reason_class: transient-dependency` (below). Findings already collected from auto reviewers do not rescue this: with no triggerable gate there is no way to establish that a round finished, so there is no defensible clean signal. Report what was collected, then halt. Exception — `RESOLVED.gateBlock == "host-family"`: the halt is reason_class: authority-boundary instead, and the attended path reports it rather than opening the selection prompt. The prompt exists to pick a different reviewer, and here there is no independent one to pick — retrying cannot change a model family. See Host-family independence.

Without config (first use or unconfigured):

1. Gate on RESOLVED.gate — with no fallback_order to authorize a ladder, that is

whichever available candidate resolve picked (the gate= token or positional alias when the caller named one, else the first canGate entry).

1. If it fails (quota, no response, CLI unavailable, etc.), present the wizard

(attended) or fail fast (unattended):

"{reviewer} couldn't complete review (reason: {reason}). Which reviewer to continue with?"

• Detected github-bots with canGate: true (e.g. "Codex bot — last seen {date}",

"CodeRabbit — last seen {date}"); unidentified bots are listed informationally, not as a choice, because there is no way to prompt them

• Codex CLI — if the CLI gate passed (omit otherwise)
• Skip, don't trigger another reviewer

1. After user picks, ask: "Use this order going forward? ({full order used so far})"

• A) Yes, remember this
• B) No, ask each time

1. If user picks A, save to primary solopreneur.json:

``bash write_solopreneur_config greenlight '{ "fallback_order": ["codex-bot", "codex-cli"], "created_at": "TIMESTAMP" }' ` (fallback_order = the user's actual config_id ordering — codex-only shown here; add gemini only for an enterprise Code Assist repo where detection finds it. TIMESTAMP` in ISO 8601.)

Unattended callers never prompt. When greenlight is invoked with the unattended argument (todos-babysit auto mode, autopilot dispatch), every "ask the user" / wizard branch above is replaced by a halt with reason_class: transient-dependency (external reviewers are down but may recover — see Escalation taxonomy): log the reviewer exhaustion, write the halt payload, and exit non-zero. The caller's own fail-safe then takes over — todos-babysit leaves the PR and notifies; autopilot's orchestrator consumes the reason_class and routes a transient-dependency halt to wait-and-retry rather than straight to blocked. Never block on input.

For reviewer selection specifically, an unattended run does not halt while a gate is still resolvable: the gate is the first available fallback_order entry and every auto reviewer is still collected. Unattended runs never identify, never retry a marked reviewer, and never add agy or grok-cli — those are attended decisions. A defensible default gate beats blocking on input; only an exhausted ladder halts.

Gemini compatibility (consumer sunset). Consumer Gemini Code Assist stopped GitHub code review on 2026-07-17; enterprise is unaffected, so gemini stays a fully valid registry entry, a legal /greenlight external gemini argument, and a legal fallback_order value. When a gemini trigger gets no response and times out, append this one line before falling through (or exhausting):

"No response from the Gemini bot. Consumer Gemini Code Assist was sunset

2026-07-17 (enterprise unaffected); if this isn't an enterprise repo, that's

expected. Falling through to the next reviewer."

Codex CLI special handling: Codex CLI doesn't poll GitHub API — reads stdout directly. Execute:

codex review --base main 2>&1

Output format: review comments with [P1], [P2], [P3] tags and file paths. Parse stdout for feedback, then process through the same Step 3 flow as GitHub bot feedback.

Feedback Detection Strategy

Core principle: use unresolved review threads + comment ID comparison. Never use timestamp filtering.

Bot feedback arrives through two channels:

| Channel | Example | Detection |

|---------|---------|-----------|

| Inline feedback (review threads) | P1 suggestions, code-level comments | isResolved == false (GraphQL) |

| Summary messages (issue comments) | "Didn't find any major issues", quota warnings | comment.id > TRIGGER_COMMENT_ID |

All threads are resolved after each round → unresolved = 0 at next round start.

GitHub issue comment IDs are globally monotonically increasing — id > TRIGGER_COMMENT_ID

reliably identifies "replies after trigger".

Pre-loop Check

Check for unresolved review threads (possibly left over from previous rounds):

UNRESOLVED=$(gh api graphql -f query='query($owner:String!,$repo:String!,$pr:Int!){
  repository(owner:$owner,name:$repo){
    pullRequest(number:$pr){
      reviewThreads(first:100){
        nodes{ isResolved }
      }
    }
  }
}' -f owner=OWNER -f repo=REPO -F pr=PR_NUMBER \
  --jq '[.data.repository.pullRequest.reviewThreads.nodes[] | select(.isResolved==false)] | length')

• UNRESOLVED == 0 → start from Step 1 (first round)
• UNRESOLVED > 0 → resolve this round's roles first (the detection block's

RESOLVED, same as the main loop), then jump to Step 3

Main Loop

# ── Initialization (after pre-flight, before entering loop) ──
# Argument parsing (see above): external_only, SELECTED_RECIPES, GATE_RECIPE and
# EFFECTIVE_SIZE are set. SIZE_MAX_ROUNDS = 3 / 5 / 10 for S / M / L (see Sizing).
# The detection block has produced RESOLVED (trigger / collect / gate).
 
round = 0
LOOP (max SIZE_MAX_ROUNDS rounds — S 3 / M 5 / L 10; see Sizing):
  round += 1
  1. Cursor ceilings must already be recorded, taken BEFORE anything pushed. The
     push wakes the auto reviewers, so a ceiling captured after it sits above
     their response and that feedback is lost for good. Note that the fix
     subagent pushes at the END of the previous round, so:
       round 1      → capture here, at loop start
       later rounds → captured in Step 3 of the previous round, immediately
                      before the fix subagent was dispatched
  2. (The previous round's fix push has already happened by this point.)
  3. Trigger every entry in RESOLVED.trigger, in parallel (Step 1).
  4. Open the wait window from RESOLVED.gate; collect from RESOLVED.collect (Step 2).
  5. Classify the round into exactly one terminal state (Step 2b) — BEFORE fixing
     anything.
  6. Write observations back (Step 2c).
  7. Act on the state:
     findings → Step 3, then back to 1
     quota    → advance past the exhausted gate (Fallback Logic: add it to
                EXHAUSTED_GATES, re-resolve with --gate <next>), back to 3
                (not a new round). NEVER re-resolve unchanged — the same gate
                comes back and the retry spins forever.
     timeout  → record triggerable:false, then advance the same way;
                no candidate left → halt
     clean    → closing sweep, end the loop

Step 1: Trigger Reviewer

First, record the per-channel cursor ceilings — before the round's push, and before posting any trigger. Feedback arrives on three channels and their ids are not comparable to each other, so one ceiling per channel. A single ceiling would miss a reviewer that only files formal reviews (verified: PR #108's Gemini). Ids, never timestamps (see Feedback Detection Strategy).

Order matters here. The push is what wakes every auto reviewer on the repo, and they can publish before this loop reaches its next statement. A ceiling captured after the push therefore sits above that response, which drops out of this round — and the next round's ceiling rises past it too, so it is lost permanently. Capturing first also means genuinely late feedback from the previous round lands above the boundary and gets collected now, which is what "late findings arrive next round" promises.

The fix subagent pushes, and it does so at the end of the previous round — so "before the push" cannot mean "at the top of this step" for any round after the first. Capture the ceilings at the last moment before anything can push: round 1 here, every later round in Step 3, immediately before dispatching the fix subagent. Re-capturing here on a later round would defeat the whole ordering, because the subagent's push already happened:

# Aggregate in jq, NOT in `gh --jq`: with --paginate, gh applies a `--jq` filter
# to each page separately and prints one result per page, so `[.[].id] | max`
# there yields one maximum per page. Without --jq, gh merges array pages into a
# single flat array first, which is what these need.
#
# DO NOT "fix" this by adding --slurp. Two reviewers have proposed it from the
# manual's wording; the real command disagrees. Measured on gh 2.92.0 against a
# deliberately paginated request (`?per_page=1`, 9 pages):
#   … --paginate            | jq -s 'length'  → 1   (one merged array…)
#   … --paginate            | jq -s '.[0]|length' → 9   (…holding every record)
#   … --paginate --slurp    | jq 'length'     → 9   (an array of 9 page arrays)
# --slurp would therefore make `.[]` yield arrays instead of objects and every
# filter below would silently match nothing. gh also documents that --slurp
# cannot be combined with --jq at all.
CUR_ISSUE=$(gh api "repos/{owner}/{repo}/issues/{pr}/comments" --paginate \
  | jq '[.[].id] | max // 0')
CUR_REVIEW_COMMENT=$(gh api "repos/{owner}/{repo}/pulls/{pr}/comments" --paginate \
  | jq '[.[].id] | max // 0')
CUR_FORMAL_REVIEW=$(gh api "repos/{owner}/{repo}/pulls/{pr}/reviews" --paginate \
  | jq '[.[].id] | max // 0')

Then trigger every entry in `RESOLVED.trigger`, in parallel, branching on the entry's own kind:

Entries absent from trigger are there on purpose: a non-gate auto reviewer (it reviews on push, so prompting it is noise) or an unidentified bot (no recipe, so there is nothing to post). The gate is always in `trigger` — auto or not — because a clean signal needs an addressable response, and re-requesting a review from an auto bot is harmless.

# TRIGGER_TIME is taken once, before any trigger is posted.
TRIGGER_TIME=$(date -u +"%Y-%m-%dT%H:%M:%SZ")
 
# Two boundaries, because collection and conclusion need opposite biases:
#
#   ROUND_TRIGGER_ID  = the LOWEST id among this round's trigger comments.
#                       COLLECT from here — wide. Triggers post in parallel, so a
#                       narrower bound would hide a fast reviewer that replied
#                       between the first trigger and the gate's.
#   GATE_TRIGGER_ID   = the id of the GATE's OWN trigger comment.
#   GATE_TRIGGER_TIME = the timestamp taken immediately before posting it.
#                       CONCLUDE from here — narrow. A gate verdict that predates
#                       its own trigger is about the PREVIOUS commit: with
#                       parallel triggers a late clean comment for the old SHA can
#                       land after some other reviewer's trigger, clear the wide
#                       bound, and close the round without ever seeing this
#                       round's fixes.
#
# Also capture the formal-review ceiling right after the gate's trigger goes out
# (`GATE_REVIEW_FLOOR`), since review ids are not comparable to comment ids and
# check [D] needs the same narrow bound.

Flow B — local CLI mode: Execute locally, wait for result directly (no polling needed). Run the entry's own recipe — the selection prompt can put either local CLI in trigger[], so hardcoding one here would run Codex when the user chose agy, or fail outright on a machine where only agy is installed:

`grok-cli` availability — the probe lives in the detection block (with the other CLI_AVAILABLE probes), not here, so it exists in exactly one place. It runs when the caller named grok-cli — a gate=/select= token, the positional alias, or a persisted fallback_order entry — and the attended "Add grok-cli" prompt path reaches the same probe: that add re-runs resolve with grok-cli appended to --cli-available only after the probe passes. If the probe fails while grok-cli was explicitly requested, treat it as an unavailable reviewer — the existing degrade paths apply; never silently substitute another reviewer without saying so.

`grok-cli` dispatch (each round the entry is in trigger[]):

# Capture and check the diff first — a non-zero git exit OR an empty diff is an
# invocation failure for this reviewer, never a clean pass, and it must SKIP
# the dispatch: handed empty input, a reviewer answers "No findings." (plus the

Parse $GROK_OUT for [P*] lines (ignore the marker line) and accumulate them into $CLI_FINDINGS tagged grok-cli, exactly as for the other local CLIs. grok may narrate in a non-English language (verified) — key off the [P*] tags and the marker, never off English prose. Exactly No findings. plus the marker → this reviewer found nothing this round. Mark it quota only when the guard above set GROK_QUOTA=true. That flag already encodes the standing iron rule — the quota strings (402 / Payment Required / usage balance exhausted) name a failure only after a non-zero exit, they never decide one, because reviewer prose can quote "rate limit" — and it is computed before the guard zeroes $GROK_OUT, while the captured text still exists to grep.

/code-review's own approval bar ("do not approve merely because behavior seems correct") is its review lens, not this loop's termination condition: the round is clean for this reviewer when it reports no new [P*] findings. The fix subagent still takes every finding through receiving-code-review and may push back on structural opinions with technical reasons — Grok is a reviewer, not a supervisor. If a first run floods the round with low-conviction [P2]s, tighten the prompt (cap the count, demand higher conviction) rather than loosening the loop's termination rule.

Codex App: run claude-cli in a PTY-enabled shell tool call. A non-PTY App call can exit zero with empty stdout; that remains an invocation failure. Retry the same checked diff and verbatim recipe once with PTY, never reinterpret empty stdout as clean.

WARNING: Do not `cd`: Execute in the current working directory. Never change directories.

In worktree workflows, the current directory is already the feature branch; any cd

(including to repo root) would make the CLI run on main, resulting in empty diffs

or reviewing the wrong changes.

Pre-check: git branch --show-current should show the feature branch, not main.

# Verify correct directory first
git branch --show-current  # confirm not on main
# Then run the command from the table above for THIS entry's recipe.

Flow A — GitHub bot mode: Comment on the PR with the entry's triggerText, record that comment's ID.

# Trigger and get comment URL (contains comment ID). Once per `trigger[]` entry
# of kind github-bot, using THAT entry's triggerText — never a name lookup.
COMMENT_URL=$(gh pr comment <PR_NUMBER> --body "<entry.triggerText>")
TRIGGER_COMMENT_ID=$(echo "$COMMENT_URL" | sed 's/.*-//')  # macOS-compatible, extract from issuecomment-{id}
 
# When THIS entry is the gate, record its own boundaries — the narrow ones every
# verdict check in Step 2 compares against.
# (before posting it: GATE_TRIGGER_TIME=$(date -u +"%Y-%m-%dT%H:%M:%SZ")
#                     GATE_REVIEW_FLOOR=$(gh api ".../pulls/{pr}/reviews" --paginate | jq '[.[].id] | max // 0'))
# GATE_TRIGGER_ID="$TRIGGER_COMMENT_ID"

`ROUND_TRIGGER_ID` (the lowest of these) is the primary filter for comment polling.

GitHub issue comment IDs are globally monotonically increasing — bot reply IDs are always

> the trigger ID. TRIGGER_TIME is used separately for reaction-based clean signal

detection (see Step 2, check [C]).

Confirm the trigger landed — per the entry's own `handshake`:

The 👀 ladder (handshake: reaction only). Wait 30 seconds after triggering and check for the reaction on that entry's own trigger comment:

sleep 30
EYES_COUNT=$(gh api repos/{owner}/{repo}/issues/comments/{TRIGGER_COMMENT_ID}/reactions \
  --jq '[.[] | select(.content == "eyes")] | length')

• Has 👀 reaction → trigger succeeded, proceed to Step 2
• No 👀 reaction → wait another 30 seconds and recheck
• Still no 👀 on second check → trigger failed, re-post the same triggerText (max 2 retries)
• 2 retries still fail → if this entry is the gate, follow Fallback Logic above

(next gate candidate, or ask / halt); if it is a non-gate reviewer, note it and carry on — the round is not held open by a reviewer that was never gating it

This step is important: @codex review comments sometimes don't trigger the bot. No 👀 means the bot didn't receive it — must re-trigger.

Step 2: Wait for Feedback

Local CLI results — Wait for stdout to complete (typically 1-3 min, set timeout 5 min).

On failure ("usage limit" in stderr, or a non-zero exit), branch on whether that CLI is the gate:

• It is `RESOLVED.gate` → follow Fallback Logic (advance past the exhausted

gate, or ask / halt). The round has lost the thing that closes it.

• It is a non-gate reviewer → note it and carry on; the gate's window is

untouched. Entering the ladder here would advance — or halt — a perfectly healthy GitHub gate because one optional extra reviewer ran out of quota.

Parse stdout:

• Has [P*] tags → those are findings from that reviewer. **Accumulate them into

$CLI_FINDINGS, tagged with which CLI produced them.** They live only in that stdout — no GitHub thread, no comment body — so anything not captured here is invisible to Step 3, and the round would classify findings, fix nothing, and re-run identically until the round cap.

• No [P*] tags, only summary paragraphs → that reviewer found nothing

`claude-cli` and `grok-cli` additionally require a positive clean signal. Their prompts ask for either [P*]-tagged findings or the exact sentence No findings. (for grok-cli, plus its nonce marker as the last non-blank line), so stdout carrying neither is an invocation failure — reviewer unresponsive — and is handled by the failure branch above, never read as a clean pass. Empty or truncated stdout from a headless CLI is indistinguishable from "reviewed and found nothing" without that sentence, and guessing clean would end the loop on a review that never ran. This is the same failure the agy recipe's completion marker guards against.

A clean CLI result does not end the loop unless that CLI is the gate. A local CLI can be triggered as an ordinary non-gate reviewer while a GitHub bot gates the round (--cli-available codex-cli puts it in trigger[] either way). Ending on its clean stdout would skip the gate's whole wait window and discard every other reviewer's findings. CLI output feeds the shared classification in Step 2b like any other channel; only a CLI that is RESOLVED.gate closes the round by finishing.

GitHub bot mode — the window belongs to the gate: it supplies both the identity that closes the round and the cadence for waiting on it.

The three checks decide when the window closes — what the round then means is Step 2b's job:

WARNING: Priority order matters: check issue comments first (clean pass or quota), then

unresolved threads. The bot may post a summary before inline comments — checking summary

first correctly identifies clean passes.

WARNING: **When matching quota or clean pass, print the first 3 lines of GATE_COMMENT_BODY

for manual verification.** Bot boilerplate text may contain keywords like "limit" causing

false positives. Be especially vigilant if it matches on the first poll. The same applies to

any other login's body read through bot_latest_comment_body — the keyword tables were tuned on

Codex and Gemini wording, and a newly added reviewer's phrasing is unverified.

WARNING: **When UNRESOLVED > 0 is detected, enter Step 3 immediately — don't wait for

more threads.** Bots may send inline comments in batches, but waiting is unnecessary —

the next review round will naturally catch any that were missed. Waiting only wastes time

and violates the "process feedback when available" principle.

Polling cadence — from `RESOLVED.gate.poll`, never a per-reviewer branch here:

sleep $FIRST_WAIT, then up to $TRIES checks $INTERVAL apart. The registry row supplies the numbers (Codex bot 60s × 20, Gemini 180s then 120s × 2, anything unverified 180s then 120s × 3), so adding a reviewer never means editing this step.

Deliberately not waiting for auto reviewers. The window closes on the gate. An auto reviewer still mid-review is not waited for — every channel's ceiling rises monotonically, so its late findings arrive next round, and on the final round they land in the closing report instead of vanishing. This is what stops "collect four reviewers" from becoming "wait for the slowest one, every round".

When the gate is a local CLI (gate.kind == "cli"), there is no poll window at all: it runs synchronously and finishing is the end of the round. After it returns, do one collection sweep across the three channels for the other collected logins, then classify.

Seeded rounds are probes, not gated rounds. When resolve seeded this round (its warning says so — nothing has acted on this repo yet) and the seeded gate's recipe has no verified login, GATE_LOGIN is empty: checks [B] and [C] can match no author, so the round will classify as timeout. That is correct, not a defect — the trigger only needs the recipe string, but proving a round finished needs an identity, and this tool has never been seen here. Its purpose is to make the tool answer once. So for this round only:

• Collect every new Bot login past the cursors, not just `collect`. Nothing

else is known about this repo, so there is no marked or unselected reviewer for this widening to wrongly admit — and without it a tool that answered with real findings would have them filtered away as "not in collect", making the probe pointless.

• Attended: offer to identify the responder immediately (Step 2c's last row) —

that is what turns the probe into a usable reviewer next run.

• No response at all: leave no state behind. Do not write triggerable: false

for a login-less recipe — there is no login to key it on, and "we could not attribute it" is not evidence that it cannot be triggered. Report that the tool is probably not installed here and move on.

Step 2b: Classify the round

Silence is not a pass. Classify every round into exactly one terminal state by walking this table top-down; the first matching row wins. Classify before touching anything — fixing first would let the loop end on a diff no reviewer has seen.

findings outranking clean is load-bearing: when the gate passes but another reviewer found something, that round must still loop — fixing and then declaring clean would end the loop on a diff no reviewer has reviewed. The opposite failure — a dead reviewer counting as a pass — is what row 3 blocks.

SIZE_MAX_ROUNDS (S 3 / M 5 / L 10) is unchanged and is what bounds a chatty auto reviewer stretching the loop; at the cap, unresolved items go into the closing report. Size S is external-only with a single reviewer and its gate resolves straight from fallback_order, so the nothing-can-gate prompt does not arise there in practice.

Step 2c: Observation write-back

After closing the window, scan the three channels for everything past this round's cursors. The scan is unfiltered by login — the write-back has to see every Bot that acted, including ones nobody selected — while findings stay restricted to collect:

round_bot_activity() {   # every Bot login that acted since the cursors
  {
    gh api "repos/{owner}/{repo}/issues/{pr}/comments" --paginate \
      | jq -r --argjson c "$CUR_ISSUE" '.[] | select(.id > $c and .user.type == "Bot") | .user.login'
    gh api "repos/{owner}/{repo}/pulls/{pr}/comments" --paginate \
      | jq -r --argjson c "$CUR_REVIEW_COMMENT" '.[] | select(.id > $c and .user.type == "Bot") | .user.login'
    gh api "repos/{owner}/{repo}/pulls/{pr}/reviews" --paginate \
      | jq -r --argjson c "$CUR_FORMAL_REVIEW" '.[] | select(.id > $c and .user.type == "Bot") | .user.login'
  } | sort -u
}

Build $OBSERVATIONS from that set plus RESOLVED:

printf '%s' "$OBSERVATIONS" \
  | node "$SCRIPTS/reviewer-state.mjs" record --repo-key "$REPO_KEY"

An empty payload is legal and rewrites nothing — a quiet round cannot reformat a hand-edited config.

Step 3: Process Feedback (via Subagent)

Processing review feedback involves extensive file reading and fixing. To avoid bloating the main conversation context, this must be delegated to a subagent.

Where you cannot dispatch a subagent, apply the fixes inline in the main context instead. The delegation exists to keep the main context small, not for correctness — so where there is no subagent to dispatch to, everything below still applies, just executed in this context. The instruction above is not weakened on Claude Code: there the subagent is mandatory, because an L-size loop that inlined ten rounds of fix processing would exhaust the context it is trying to protect. That cost is also why Codex is bounded to sizes S and M (Host support). The parent is the only writer either way — inline or delegated, one process commits and pushes.

3a. Get full content of all unresolved threads:

gh api graphql -f query='query($owner:String!,$repo:String!,$pr:Int!){
  repository(owner:$owner,name:$repo){
    pullRequest(number:$pr){
      reviewThreads(first:100){
        nodes{
          id
          isResolved
          comments(first:5){
            nodes{
              databaseId
              author{ login }
              path
              body
              line
            }
          }
        }
      }
    }
  }
}' -f owner=OWNER -f repo=REPO -F pr=PR_NUMBER \
  --jq '[.data.repository.pullRequest.reviewThreads.nodes[] | select(.isResolved==false) | {
    threadId: .id,
    comments: [.comments.nodes[] | {databaseId, author: .author.login, path, line, body}]
  }]'

No timestamp filtering needed. Since all threads processed each round are resolved

at its end, unresolved threads here are exactly the feedback still outstanding.

Apply the same author filter as Step 2's check [A] — keep a thread when its author is not a Bot (humans always count) or its [bot]-stripped login is in collect. A thread from a bot nobody selected, or one marked unresponsive, is left unresolved on purpose: it is not fixed, not resolved, and appears in the closing report for the user to judge. Silently resolving it would erase a finding no one ever read.

Then append `$BODIED_FINDINGS` and `$CLI_FINDINGS` to the payload. Threads are only one of the channels a reviewer can speak on: the [B2] sweep collected the issue-comment and formal-review bodies, and a local CLI's findings exist only in its stdout. All of them must reach the fix subagent alongside the threads. Dispatching threads alone is why a body-only or CLI-only finding could classify as findings, loop, and still hand the subagent nothing to act on — re-running identically to the round cap. These items have no thread id, so they are never part of 3c's resolve list; they have nothing to resolve.

3b. Process feedback:

1. Invoke `receiving-code-review` skill first (via Skill tool) to load the processing mindset.

If the skill is not available, proceed without it — evaluate each suggestion using your own judgment on whether it's a genuine issue or a false positive.

1. Check whether any suggestions were already pushed back in previous rounds. If so, reconsider. If still deciding to push back, consider whether to add a code comment or note in CONTEXT.md so the reviewer understands the reasoning. If the same issue has been raised multiple times, it can be ignored.
2. Re-capture the three cursor ceilings now, before dispatching. The subagent

commits and pushes, and that push wakes every auto reviewer — so this is the last moment at which a ceiling is guaranteed to sit below their response. Capturing at the top of the next round instead would place the ceiling above it, dropping that feedback from the next round and, since ceilings only rise, from every round after. Use the same three commands as Step 1.

1. Dispatch subagent (via Agent tool) to handle all unresolved threads. Prompt must include:

• Full content of all unresolved threads (body, path, line, thread id)
• $BODIED_FINDINGS — the issue-comment / formal-review findings from 3a,

each tagged with its reviewer and channel, and marked as having no thread id

• $CLI_FINDINGS — the [P*] findings parsed from each local CLI's stdout,

tagged with which CLI produced them; likewise no thread id

• Instruction: "Use the superpowers:receiving-code-review skill framework to evaluate each suggestion. If the skill is not available, evaluate each suggestion on its own merits — fix genuine issues, push back on false positives with solid technical reasoning."
• Instruction: "False positives require solid technical reasoning to push back"
• Instruction: "After fixes, commit + push"
• Inner verify loop (when VERIFY_CMD is set): run VERIFY_CMD against the

working tree before committing; commit only on a green verify; on the 3rd failure return a structured halt (no commit). Include the anti-gaming guard. See Inner verify loop.

• Commit message format: fix: code review fixes — <summary>
• If packaged files (e.g., .skill) are involved, remind to re-package

``text Agent( description: "Process PR code review feedback", prompt: "Here are the unresolved review threads for PR #<NUMBER>:\n\n<THREADS>\n\nUse the receiving-code-review skill framework to evaluate each one, fix items worth fixing. If a VERIFY_CMD was provided, follow the Inner verify loop: run it against the working tree before committing and commit only when it passes (3rd failure → structured halt, no commit). Then commit + push.", mode: "auto" ) ``

Halt check (before 3c). If the subagent returned a structured halt (no commit), do NOT resolve threads and do NOT start another round — stop at the blocked exit, report blocked, and reference the halts/ payload. Resolving threads on a halt would hide findings that were never actually addressed.

3c. Resolve all processed threads:

After subagent completes, the main conversation resolves all threads processed this round:

for THREAD_ID in <all unresolved thread IDs>; do
  gh api graphql -f query='
    mutation($id:ID!){
      resolveReviewThread(input:{threadId:$id}){
        thread{ id isResolved }
      }
    }' -f id="$THREAD_ID"
done

Resolve the threads processed this round (both fixed and pushed-back) — and only those; see the author-filter note in 3a. After confirming push succeeded, maintain the current gate (no per-round reset), immediately return to Step 1 to trigger the next review round. No need to wait for a reviewer that is auto on this repo: it re-reviews on push by itself, and its threads are picked up by the next round's Step 2 poll.

Exit Conditions

After each Step 3 fix-and-push, must return to Step 1 for another round until one of these conditions is met:

1. No new suggestions (clean pass)

• The round classified as `clean` in Step 2b:

the gate responded (an item or a 👍) and nobody produced a new finding. A silent gate is timeout, never this.

• Before ending, do one final sweep across the three channels for late arrivals and

report anything unprocessed without fixing it — a fix applied now would end the loop on a diff no reviewer has looked at.

2. Only repeated/low-value suggestions (push-back exit)

• All suggestions this round were already pushed back in previous rounds (same file + same topic)
• Or all suggestions this round were evaluated as not worth fixing (with solid technical reasoning)
• Stop fixing — end the loop

3. Maximum round protection

• Max `SIZE_MAX_ROUNDS` rounds — S 3 / M 5 / L 10 by effective size (see Sizing). If exceeded, stop and notify user, let them decide whether to continue

On exit:

1. Notify user: "Review loop complete" + exit reason + last round's reviewer feedback
2. Report: total rounds run, items fixed, items pushed back, which gate closed the loop,

which other reviewers were collected, and any leftover items from the closing sweep

1. Append the Flags section (Inner verify loop → Flags) if anything flagged this

run — including "no objective verifier configured for this loop"; omit it otherwise. On a halt, report blocked and reference the halts/ payload path.

1. Ask user whether to merge the PR

Important Notes

• Between review rounds, don't rush to fix — use the receiving-code-review framework to evaluate each suggestion first
• If the same issue is raised for two consecutive rounds, re-evaluate before deciding to push back
• If fix volume is large (>20 lines), that is a decision-point flag (see Escalation taxonomy): attended runs surface it inline and discuss with the user before implementing; unattended runs proceed and record it in the Flags section
• Use sleep for polling, not busy-wait, to avoid resource waste
• Reviewer switches stop to ask the user (when no config), or auto-switch per config order with notification
