Claude Compaction Restore

Use this skill to preserve continuity before Claude Code compacts and to restore continuity after compaction. Do the work described here; do not merely explain the protocol.

If You Are About To Compact

Prepare durable continuity before the context boundary.

1. Identify the active task, queue item, mission/slice, branch or commit, and

current working directory.

1. Record the current state: decisions made, files changed, commands/tests run,

evidence produced, blockers, caveats, and the next concrete step.

1. Create or update a durable mental-model restore map. This map is the main

artifact future-you will use to rebuild context after compaction.

1. In the restore map, write an ASCII file/folder tree of every path that

mattered to your working mental model during this session. Include:

• the active queue item or mission packet;
• mission notes, progress, decisions, and evidence files;
• Claude memory/project notes you used or wrote, especially when the memory

folder is shared by many agents;

• files with active edits or recently inspected source;
• root instructions such as AGENTS.md, CLAUDE.md, or README.md;
• as-built docs, codemaps, conventions, skills, and product docs needed

before code/review work;

• source files, tests, scripts, UI evidence, screenshots, logs, or reports

that shaped your current state.

1. For every file or folder in the tree, add a short note explaining why it

matters and whether it is required reading after compaction.

1. Write any important glue context that is not already on disk into the

handoff/restore map. This includes assumptions, partial conclusions, failed paths, and why the listed files fit together.

1. In the compaction summary, include the restore map path and the top required

reading paths from that map.

If You Just Compacted

Treat your memory as unreliable until you restore from durable evidence. Restoration is your current task. Do not wait for a future user request or a new task assignment before reading the required files.

1. Read any restore prompt, marker path, packet path, transcript path, restore

map, or extra instruction file named by the operator or OpenRig.

1. Run the restore script from this skill:

node ~/.claude/skills/claude-compaction-restore/scripts/restore-from-jsonl.mjs --out /tmp/claude-compaction-restore

If the prompt names a specific Claude JSONL transcript, pass it explicitly:

node ~/.claude/skills/claude-compaction-restore/scripts/restore-from-jsonl.mjs /path/to/session.jsonl --out /tmp/claude-compaction-restore

1. Read the generated restore-instructions.md.
2. Read the generated touched-files.md.
3. Find and read the mental-model restore map if one exists. Treat it as the

highest-value guide to which memory files, mission files, source files, and docs mattered before compaction.

1. Identify the important files for the active task. The touched-file list is

a triage aid, not a complete inventory.

1. Read every important file in full. Prioritize the restore map, Claude memory

files named in the map, Markdown state/planning files, queue/mission packets, source files with active edits, root instruction files, and as-built or codemap docs.

1. After the required reads are complete, state:

restored from packet at <path>; resumed at step <X>

Include the main files you read in full when you make that statement.

Required Read-Depth Audit

After the first restore pass, audit yourself before continuing.

1. List every file, packet, marker, restore map, instruction file, and source

document you were asked to read during restore.

1. Mark each item as FULL, PARTIAL, or NOT_READ.
2. You will be given a task where all of these files are required reading in

order to understand the task.

1. Do not optimize for token conservation.
2. Read every PARTIAL or NOT_READ item in full now.
3. Report the final read-depth table before doing any substantive task work.

Guardrails

• Compaction is survival, not housekeeping — never compact to free space, "lean" a seat, or capture/prepare an agent starter (the rig agent-image library). It is lossy (a compacted Claude is confident-but-hollow); compact only when a seat is genuinely near its context limit, with a before/after plan. A starter's value is being functional, not small — see the agent-starters skill.
• Do not silently launch fresh after compaction.
• Do not continue from memory when restore evidence exists.
• Do not defer required restore reading until a later user task. The restore is

the current task.

• Do not skip root instructions, as-built docs, or codemaps before product

code/review work.

• Do not treat the generated touched-file list as exhaustive.
• Do not mark a file FULL unless you actually read the full file content

after compaction.

• Do not resume task work until the restore sentinel and read-depth audit are

complete.

Failure Modes To Avoid

1. Confidently-wrong restoration: claiming restoration after reading only

the touched-file list or summary.

1. Partial restore: reading the first few files, then continuing before the

full reading list is complete.

1. Skipping project instructions: missing AGENTS.md, CLAUDE.md,

README.md, as-built docs, or codemaps that govern the task.

1. Treating the packet as exhaustive: ignoring mission or workspace files

that are important but were not discovered by the script.

1. Waiting for the next task: treating restore reading as conditional on a

future user assignment instead of completing it immediately.
