version: "1.0.1" name: plan-file-management description: Structural CRUD and reordering operations on plan files via the i2code plan CLI — insert/replace/delete/reorder threads and tasks, mark tasks/steps complete or incomplete, fix numbering, and query plan structure (get-next-task, get-thread, get-summary, list-threads). Claude MUST use this skill (not raw file edits) for any change to a plan file's threads, tasks, or steps, and for reading plan structure programmatically.

Plan File Management

Structural operations on plan files such as renumbering threads and tasks.

All operations are subcommands of the i2code CLI tool, invoked as:

i2code plan <subcommand> <plan_file> [options]

Schemas

JSON arguments to the commands below MUST conform to these schemas:

• references/task.schema.json — the object passed via --task-file and the items of the --tasks / --tasks-file arrays.
• references/thread.schema.json — the object passed via no single flag today; its tasks[] array is what --tasks / --tasks-file accept, and its title / introduction fields correspond to the --title / --introduction flags on insert-thread-before, insert-thread-after, and replace-thread.

The schemas are the source of truth for field names, required-ness, and value constraints (including the task_type enum). The per-command sections below describe how each command consumes these objects but do not re-state the schema.

fix-numbering

Renumber all threads and tasks sequentially. Run this after arbitrary edits made outside the script.

i2code plan fix-numbering <path-to-plan-file>

Run this after:

• Inserting or deleting threads or tasks
• Rearranging plan sections
• When the user asks to renumber or fix numbering

mark-task-complete

Mark a task and all its steps as complete. Optionally appends to change history if rationale is provided.

i2code plan mark-task-complete <plan_file> --thread <N> --task <M> [--rationale <text>]

Errors if the task does not exist or is already complete.

mark-task-incomplete

Mark a completed task and all its steps as incomplete. The reverse of mark-task-complete. Optionally appends to change history if rationale is provided.

i2code plan mark-task-incomplete <plan_file> --thread <N> --task <M> [--rationale <text>]

Errors if the task does not exist or is already incomplete.

reorder-threads

Reorder threads according to a specified ordering, then auto-renumber all threads and tasks.

i2code plan reorder-threads <plan_file> --order <comma-separated-thread-numbers> --rationale <text>

Example: --order 3,1,2 moves thread 3 to position 1, thread 1 to position 2, thread 2 to position 3.

Errors if --order does not contain exactly the set of existing thread numbers.

insert-thread-before

Insert a fully structured thread before a specified thread, then auto-renumber.

i2code plan insert-thread-before <plan_file> --before <N> --title <title> --introduction <text> --tasks <json> --rationale <text>

i2code plan insert-thread-before <plan_file> --before <N> --title <title> --introduction <text> --tasks-file <path> --rationale <text>

The --tasks argument is a JSON array of task objects (see spec for schema). Use --tasks-file instead of --tasks when the JSON is large or contains characters that are difficult to escape in the shell. Write the JSON file to the idea directory (alongside the plan file) and delete it after use. --tasks and --tasks-file are mutually exclusive; exactly one is required.

insert-thread-after

Insert a fully structured thread after a specified thread, then auto-renumber.

i2code plan insert-thread-after <plan_file> --after <N> --title <title> --introduction <text> --tasks <json> --rationale <text>

i2code plan insert-thread-after <plan_file> --after <N> --title <title> --introduction <text> --tasks-file <path> --rationale <text>

Use --tasks-file instead of --tasks when the JSON is large or contains characters that are difficult to escape in the shell. Write the JSON file to the idea directory (alongside the plan file) and delete it after use. --tasks and --tasks-file are mutually exclusive; exactly one is required.

get-next-task

Return the first uncompleted task across the plan, with full metadata and steps. Prints a message if all tasks are complete.

i2code plan get-next-task <plan_file>

list-threads

Return all threads with their numbers, titles, and task completion counts.

i2code plan list-threads <plan_file>

get-summary

Return the plan's name, idea type, overview, and progress (thread count, task count, completed task count).

i2code plan get-summary <plan_file>

get-thread

Return a specific thread's full content including number, title, introduction, and all tasks with their metadata and steps.

i2code plan get-thread <plan_file> --thread <N>

Errors if the thread does not exist.

mark-step-complete

Mark a single step as complete. Appends to change history.

i2code plan mark-step-complete <plan_file> --thread <N> --task <M> --step <S> --rationale <text>

Errors if the step does not exist or is already complete.

mark-step-incomplete

Mark a single completed step as incomplete. The reverse of mark-step-complete. Appends to change history.

i2code plan mark-step-incomplete <plan_file> --thread <N> --task <M> --step <S> --rationale <text>

Errors if the step does not exist or is already incomplete.

replace-thread

Replace a thread's entire content (title, introduction, tasks) in place, then auto-renumber.

i2code plan replace-thread <plan_file> --thread <N> --title <title> --introduction <text> --tasks <json> --rationale <text>

i2code plan replace-thread <plan_file> --thread <N> --title <title> --introduction <text> --tasks-file <path> --rationale <text>

Use --tasks-file instead of --tasks when the JSON is large or contains characters that are difficult to escape in the shell. Write the JSON file to the idea directory (alongside the plan file) and delete it after use. --tasks and --tasks-file are mutually exclusive; exactly one is required.

Errors if the thread does not exist.

insert-task-before

Insert a task before a specified task within a thread, then auto-renumber tasks.

i2code plan insert-task-before <plan_file> --thread <N> --before <M> --title <title> --task-type <INFRA|OUTCOME> --entrypoint <cmd> --observable <text> --evidence <cmd> --steps <json> --rationale <text>

i2code plan insert-task-before <plan_file> --thread <N> --before <M> --task-file <path> --rationale <text>

The --steps argument is a JSON array of step description strings. Use --task-file instead of the individual task options when the JSON is large or contains characters that are difficult to escape in the shell. The file must contain a JSON object with title, task_type, entrypoint, observable, evidence, and steps fields. Write the JSON file to the idea directory (alongside the plan file) and delete it after use. --task-file and the individual task options are mutually exclusive; exactly one set is required.

insert-task-after

Insert a task after a specified task within a thread, then auto-renumber tasks.

i2code plan insert-task-after <plan_file> --thread <N> --after <M> --title <title> --task-type <INFRA|OUTCOME> --entrypoint <cmd> --observable <text> --evidence <cmd> --steps <json> --rationale <text>

i2code plan insert-task-after <plan_file> --thread <N> --after <M> --task-file <path> --rationale <text>

Use --task-file instead of the individual task options when the JSON is large or contains characters that are difficult to escape in the shell. The file must contain a JSON object with title, task_type, entrypoint, observable, evidence, and steps fields. Write the JSON file to the idea directory (alongside the plan file) and delete it after use. --task-file and the individual task options are mutually exclusive; exactly one set is required.

reorder-tasks

Reorder tasks within a thread according to a specified ordering, then auto-renumber tasks.

i2code plan reorder-tasks <plan_file> --thread <N> --order <comma-separated-task-numbers> --rationale <text>

Example: --thread 1 --order 3,1,2 moves task 1.3 to position 1.1, task 1.1 to position 1.2, task 1.2 to position 1.3.

Errors if --order does not contain exactly the set of existing task numbers in the thread, or if the thread does not exist.

move-task-before

Move a task to before another task within the same thread, then auto-renumber tasks.

i2code plan move-task-before <plan_file> --thread <N> --task <M> --before <P> --rationale <text>

Example: --thread 1 --task 6 --before 3 moves task 1.6 to the position before task 1.3.

Errors if the thread or either task does not exist, or if task and before are the same.

move-task-after

Move a task to after another task within the same thread, then auto-renumber tasks.

i2code plan move-task-after <plan_file> --thread <N> --task <M> --after <P> --rationale <text>

Example: --thread 1 --task 1 --after 3 moves task 1.1 to the position after task 1.3.

Errors if the thread or either task does not exist, or if task and after are the same.

replace-task

Replace a task's content in place within a thread, then auto-renumber tasks. Equivalent to delete-task followed by insert-task but atomic.

i2code plan replace-task <plan_file> --thread <N> --task <M> --title <title> --task-type <INFRA|OUTCOME> --entrypoint <cmd> --observable <text> --evidence <cmd> --steps <json> --rationale <text>

i2code plan replace-task <plan_file> --thread <N> --task <M> --task-file <path> --rationale <text>

The --steps argument is a JSON array of step description strings. Use --task-file instead of the individual task options when the JSON is large or contains characters that are difficult to escape in the shell. The file must contain a JSON object with title, task_type, entrypoint, observable, evidence, and steps fields. Write the JSON file to the idea directory (alongside the plan file) and delete it after use. --task-file and the individual task options are mutually exclusive; exactly one set is required.

Errors if the thread or task does not exist.

delete-task

Remove a task from a thread, then auto-renumber remaining tasks.

i2code plan delete-task <plan_file> --thread <N> --task <M> --rationale <text>

Errors if the thread or task does not exist.

delete-thread

Remove a thread entirely, then auto-renumber remaining threads and tasks.
