Generate Plan

Turn a single PRD into a phased implementation plan made of tracer-bullet vertical slices. Output is one file at <cwd>/.plans/<feature>/plan.md, sibling of the source prd.md.

Inputs and outputs

One PRD → one plan file. One invocation processes exactly one PRD. Never aggregate multiple PRDs into a single plan; if the user wants that, redirect them to merge at the discussion stage and regenerate a single PRD.

• Input: <cwd>/.plans/<feature>/prd.md — a finalized PRD.
• Output: <cwd>/.plans/<feature>/plan.md. The <feature> slug must equal the source PRD's folder slug — keeps the PRD ↔ plan link 1:1.
• No draft checkpoint. One-shot — if interrupted mid-quiz, restart from step 1.

Workflow

1. Discover the PRD

Glob <cwd>/.plans/*/prd.md.
