PRD — Product Requirements Document

Translate product vision and research into clear, actionable engineering specifications. Produces PRD-[product-name].md output files following an 8-section structure.

Output file naming: PRD-[product-name].md (e.g., PRD-sso-invite-flow.md)

Argument Resolution

PRODUCT = "$ARGUMENTS"  # Product name or feature, e.g., "SSO invite flow"

Task Management

# 1. Create main task IMMEDIATELY
TaskCreate(subject="Write PRD: {PRODUCT}", description="8-section PRD with user stories and acceptance criteria", activeForm="Writing PRD for {PRODUCT}")

# 2. Create subtasks for each phase
TaskCreate(subject="Scope clarification", activeForm="Clarifying PRD scope")                       # id=2
TaskCreate(subject="Research and memory check", activeForm="Researching prior PRDs")               # id=3
TaskCreate(subject="Draft 8-section PRD", activeForm="Drafting PRD sections")                      # id=4
TaskCreate(subject="Write user stories and acceptance criteria", activeForm="Writing user stories") # id=5
TaskCreate(subject="Write output file", activeForm="Writing PRD file")                             # id=6

# 3. Set dependencies for sequential phases
TaskUpdate(taskId="3", addBlockedBy=["2"])  # Research needs scope first
TaskUpdate(taskId="4", addBlockedBy=["3"])  # Drafting needs research context
TaskUpdate(taskId="5", addBlockedBy=["4"])  # Stories need draft structure
TaskUpdate(taskId="6", addBlockedBy=["5"])  # Output needs all sections done

# 4. Before starting each task, verify it's unblocked
task = TaskGet(taskId="2")  # Verify blockedBy is empty

# 5. Update status as you progress
TaskUpdate(taskId="2", status="in_progress")  # When starting
TaskUpdate(taskId="2", status="completed")    # When done — repeat for each subtask

Memory Integration

# Search for prior PRDs and product decisions
mcp__memory__search_nodes(query="{PRODUCT} PRD requirements")

# After PRD is written, store key decisions
mcp__memory__create_entities(entities=[{
  "name": "PRD-{product-slug}",
  "entityType": "document",
  "observations": ["PRD written for {PRODUCT}", "Key objectives: ..."]
}])

The 8-Section PRD Template

Load Read("${CLAUDE_SKILL_DIR}/references/prd-template.md") for the full template with all 8 sections (Summary, Contacts, Background, Objective, Market Segments, Value Propositions, Solution, Release), priority levels, and NFR categories.

User Stories & Acceptance Criteria

Load Read("${CLAUDE_SKILL_DIR}/references/user-stories-guide.md") for INVEST criteria, story format, Gherkin acceptance criteria, and Definition of Ready/Done.

Value Proposition Canvas

Load Read("${CLAUDE_SKILL_DIR}/references/value-prop-canvas-guide.md") for the canvas template and fit check process. Every Value Map item must correspond to a Job, Pain, or Gain.

Go/No-Go Gate Criteria

Load from rules: Read("${CLAUDE_SKILL_DIR}/rules/strategy-go-no-go.md") for stage gate criteria and scoring thresholds (Go >= 7.0 | Conditional 5.0-6.9 | No-Go < 5.0).

Rules (Load On-Demand)

• research-requirements-prd.md — INVEST user stories, PRD template, priority levels, DoR/DoD
• strategy-value-prop.md — Value proposition canvas, JTBD framework, fit assessment
• strategy-go-no-go.md — Stage gate criteria, scoring, build/buy/partner decision matrix

References

• output-templates.md — Structured JSON output schemas for PRD, business case, and strategy artifacts
• value-prop-canvas-guide.md — Detailed value proposition canvas facilitation guide

Output

After generating the PRD, write it to disk:

Write(f"PRD-{product_slug}.md", prd_content)
TaskUpdate(status="completed")

Plan-mode filenames (CC 2.1.111+): If this skill enters plan mode (via EnterPlanMode) before writing the PRD, CC 2.1.111 names the resulting plan file after the prompt stem rather than random words. To get a clean filename, include the product slug in the plan-mode prompt (e.g. EnterPlanMode("PRD: authentication-rework") → plans/prd-authentication-rework.md). Before 2.1.111, plan filenames were plans/swift-cobra.md etc. — review and rename as needed.

Chain: Next Steps

After PRD is approved, chain into implementation:

/ork:implement PRD-{product-slug}.md
