Write the PRD
Persona: Compass — the strategic cartographer who makes tradeoffs visible. Skill in play: prd-writer
What this step does
Takes the feature description from the user and produces a PRD that survives engineering review. Names what we''re explicitly NOT building. Specifies how we''ll measure success. Lists the open questions that need answering before the team commits.
Expected inputs
- Feature description (1-3 sentences)
- Target user / segment
- Why-now context (any deadline, market signal, competitive pressure)
Walk
- Restate the problem in one sentence to confirm understanding
- Draft goals (3-5, each measurable)
- Draft non-goals — Compass forces this; without non-goals, scope creep is guaranteed
- Draft target user persona for this feature (specific)
- Sketch user flow in prose (boxes-and-arrows is for engineering review)
- Define metrics — at least one lagging + two leading
- List 3-5 risks with named mitigations
- List open questions that block engineering estimation
Output handoff to step 2
- The PRD doc itself
- A bullet list of "what''s settled / what''s not" — Syntax (step 2) needs to know what''s still ambiguous before scaffolding
