PRD Management Skill

Actions

Generate Full PRD

Generate a complete prd.json following Ralph's format with phased user stories. Acceptance criteria for every story MUST include: "Tests written first (TDD)"

Add Story

Add a new user story to the existing prd.json:

{
  "id": "PX-NNN",
  "phase": N,
  "priority": N,
  "title": "...",
  "description": "...",
  "acceptanceCriteria": ["Tests written first (TDD)", "..."],
  "passes": false
}

Status

Read prd.json and progress.txt, report:

• Total stories vs completed
• Current phase progress
• Next story to implement
• Estimated remaining iterations

Test Spec

Generate a test case list for a specific story:

1. Read the story from prd.json
2. Identify behavioral test cases (happy path, edge cases, errors)
3. Output numbered list of it('...') descriptions
4. Specify target test file(s)

Rules

• Story IDs follow format: P{phase}-{number} (e.g., P1-001, P2-005)
• Each story must be completable in one context window
• Acceptance criteria must be verifiable by automated checks
• Stories are ordered by priority (lower = higher priority)
• ALL stories must include "Tests written first (TDD)" in acceptance criteria
