What this skill does

Transforms accepted PDRs into a comprehensive, self-contained PRD.md using a three-phase DAG:

1. Plan Agent: Analyze PDRs, detect feature-areas, generate customized DAG, get user approval
2. Execute Agent: Generate sections per feature-area with mandatory checkpoint after Requirements
3. Summarize Agent: Aggregate sections, resolve conflicts, produce unified PRD.md

Output:

• docs/adlc/product/PRD.md — self-contained product requirements (the shared layout; legacy repo-root PRD.md stays read-compatible)
• {REPO_ROOT}/.adlc/product/sections/{feature-area}/{section}.md — intermediate section files
• Accepted PDRs moved to {REPO_ROOT}/docs/adlc/memory/pdr/ (the shared layout canonical memory root)

When to use

• After /product-clarify has approved PDRs
• After /product-init to document existing product
• PDR updates requiring PRD regeneration

When NOT to use

• No Accepted PDRs (run /product-clarify first)
• Minor PRD edits (edit PRD.md directly)

Pre-Flight Validation

Before starting, verify prerequisites:

1. Check PDRs exist: {REPO_ROOT}/.adlc/drafts/pdr/PDR-*.md
2. Check for Accepted PDRs: Count files with status "Accepted"
   • If zero: STOP and output:

     Cannot proceed: No Accepted PDRs found.
     Run /product-clarify to review and approve PDRs first.
     

   • If ≥1: Proceed
