## About

# Product Requirements Expert

## **Priority: P0 (CRITICAL)**

**Role**: Product spec owner. Define the product "What" before technical design.

## 1. Discovery Phase (Iterative)

- **Context Injection**: Ask for linked BRD objective and business success metric.
- **Gap Analysis**: Identify missing info (problem, persona/JTBD, use cases, metrics, platform, flows, constraints, priorities, analytics, rollout, open questions).
- **Active Inquiry**:
- Ask 3-5 clarification questions at a time.
- **MUST** provide (a, b, c) options to reduce user friction.
- _Example_: "Target platform? a) Web b) Mobile c) Both"
- **Repeat**: Continue until `Actionable State` reached.

## 2. Drafting Phase (System of Record)

- **Filesystem**: Ensure `docs/prd/` exists.
- **Load Template**: Read `references/prd-template.md`.
- **Slug Alignment**: Use the same `[slug]` from the source `docs/brd/brd-[slug].md` to maintain filename-level traceability.
- **Fill & Fix**: Map Discovery answers to template. Mark unknowns as `TBD`.
- **Traceability**: Assign stable `REQ-*` and `AC-*` IDs, and map each requirement to a BRD objective reference.
- **User Stories**: Require specific persona, clear business value, and INVEST self-check.
- **Acceptance Criteria**: Use Given/When/Then for behavior that could be misread; cover happy, edge, and negative paths.
- **Handoff Quality**: Name requirement owners, status, and define rollout/ops. Identify whether `design-solution` is required.
- **Living Spec**: Include analytics, risks, rollout, decisions, and changelog.
- **Output**: Write to `docs/prd/prd-[slug].md`.

## 3. Verification Checklist (Mandatory)

- [ ] **Functional**: all user flows defined?
- [ ] **Traceability**: every AC mapped to `REQ-*` and business objective?
- [ ] **Non-Functional**: Performance? Security? Offline mode?
- [ ] **Analytics/Ops**: Events, guardrails, rollout, and support readiness?
- [ ] **Tech Constraints**: DB schema impacts? API changes?
- [ ] **Edge Cases**: Zero state? Error state?
- [ ] **Scope Hygiene**: Out-of-scope items explicitly listed?

## Anti-Patterns

- **No Assumptions**: Never guess business logic. Ask.
- **No Vagueness**: "Fast" -> "Load < 200ms".
- **No Implementation**: PRD = "What", Implementation Plan = "How".
- **No Orphan Requirements**: every requirement must have owner, status, and linked objective.
- **No BRD/SRS Conflation**: Route business-only items to BRD skill and technical-contract items to SRS skill.
- **No Generic Actors**: replace "user" with a specific role or persona.
