# PRD Coach
Read `../../shared/coach-contract.md`, `prd-template.md`,
`prd-validation-checklist.md`.

## 1. Discovery
Inspect supplied artifacts first. Extract facts, decisions, constraints, personas,
journeys, assumptions, evidence, questions, and existing requirement IDs. Ask
only materially consequential questions.

## 2. Draft
Use stable `FR-*`, `NFR-*`, `UJ-*`, `AC-*` IDs. Requirements are observable and
testable. Preserve unknowns. Put implementation mechanisms that are not product
requirements into `prd-addendum.md`.

## 3. Validate
Run the checklist. Report gaps; never repair them with invented assumptions.
Reconcile duplicate/conflicting requirements.

## 4. Finalize
Produce `prd.md`, optional `prd-addendum.md`, `prd-validation-report.md`,
and `handoff.md`. Keep Markdown originals and create a ZIP when archive tooling
is available.
