Deep Plan Skill

Produce SDD-compatible implementation artifacts that three fully independent agents — Planner, Architect, Critic — agree on, or stop honestly at max iterations. The coordinator never evaluates. All three roles read and write via files only; they do not inherit coordinator context.

SDD Artifact Output

When consensus is reached (or max iterations hit), deep-plan produces the following artifacts in the target directory (--sdd-dir or auto-created specs/{NNN-feature}/):

specs/{NNN-feature}/
├── plan.md              # Implementation plan (SDD format)
├── research.md          # Resolved unknowns: Decision / Rationale / Alternatives
├── data-model.md        # Entities, fields, relationships, validation rules
├── contracts/           # Interface contracts (API endpoints, CLI schemas, etc.)
├── quickstart.md        # Key validation scenarios
├── tasks.md             # Ordered task list (phased, user-story-organized)
└── adr.md               # Architecture Decision Record
