name	description
todo-plan	Create and append plan blocks to TODO.md when the user asks for a plan or mentions plan/计划/TODO/待办; auto-merge or split related tasks.

TODO Plan Writer

Trigger guard

• Only run if the user message explicitly contains one of: plan, 计划, TODO, 待办.

Output target

• Append plan blocks to TODO.md (at file end).
• Do not modify other files.

Planning rules

• Use create-plan style reasoning: intent -> scope -> action items; include validation/risks when relevant.
• Title: concise "module + action" (2-6 words or 6-12 chars).
• Multiple tasks:
  • Merge into one Plan if same module/goal.
  • Split if different modules/goals.

Formatting rules

• Use the template below verbatim.
• Always keep a blank line after the ## Plan: ... header.
• Keep existing TODO.md English structure and indentation.
• Use [ ] for each action item line.
• If notes are not obvious, use - TBD.
• Line endings: LF.

## Plan: <title>

- Goal: <one-line objective>

  - In: <what is included>
  - Out: <what is excluded>
- Actions:
  [ ] <action item>
  [ ] <action item>
