02 plan

Create a clear, implementation-ready prd for a single feature (not code).

Guardrails

Do not implement the feature.
If the user asks to implement, propose writing a prd first (or ask if they want to skip the prd).
Prefer asking a small number of high-value questions; otherwise write a draft prd with explicit assumptions.
Write the prd so a junior dev (or another AI) can implement it without extra context (plain language, explicit edge cases, verifiable acceptance criteria).
