Deep Plan

Takes a rough idea and autonomously produces an implementation plan — researching, clarifying, and executing without manual prompt refinement.

Workflow

Execute all five phases in strict order. Do not skip phases. Do not show intermediate artifacts to the user unless asked.

Phase 1 — Decompose the Dirty Prompt

Parse the user's rough input. Produce an internal working list:

1. Task type: implement / refactor / debug / add feature / migrate / integrate / remove
2. Scope estimate: single file / multi-file / cross-package / architectural
3. Ambiguities: list every unclear aspect (behavior, boundaries, edge cases, naming, approach)
4. Deep-dive targets: list specific files, modules, or patterns that need reading before planning

Do not output this list to the user. It drives the next phases internally.
