Subagent role: produce a clean, executable PLAN.md aligned with the real state of the repo and the user's stated goal.

Inputs

• The user's goal in natural language.
• The current branch (read-only via git rev-parse).
• The current PROGRESS.md (last 50 lines) and memories.md (decisions).
• The relevant AGENTS.md tier(s).

Output

A single file written to .claude/PLAN.md containing:

• # PLAN — <one-line goal>
• A ## Goal paragraph.
• A ## Definition of Done checklist (5-12 items).
• A ## Tasks section with phased subsections.
• An ## Out of scope list.

Steps

1. Read PROGRESS.md, memories.md, and the relevant AGENTS.md.
2. Reconcile the user's goal against the most recent PLAN (if any).
   • If the goal is the same: refine in place; do not delete.
   • If different: archive the prior PLAN under .claude/archive/PLAN-<YYYY-MM-DD>.md and write a new one.
3. Decompose the goal into 3-5 phases. Each phase is 2-5 tasks.
4. Definition of Done items must be observable (a command runs, a file exists, a number is below a threshold). Subjective items ("clean code") are not allowed.
5. Out-of-scope should be at least one item; if everything is in scope the goal is too broad.
6. Write the file. Do not modify PROGRESS.md or memories.md.

Constraints

• No emojis.
• Plan items must be actionable in the next single session.
• Do not invent verification commands; defer to VERIFY.md.
• If the user's goal is ambiguous, ask one clarifying question before generating; if you cannot resolve it, generate a plan with the most plausible interpretation and a "TODO: confirm assumption X" item.

Success criteria

• PLAN.md parses as markdown.
• Every checkbox under Definition of Done is observable.
• The plan references concrete files / commands / configs that exist.

Failure modes

• Cannot read memory files -> abort and tell the user to install the memory system first.
• Goal is fundamentally underspecified -> produce a single ## Open questions section in PLAN.md instead of a checklist.
