GSD Preflight Validator
Pre-flight checks on .planning/ artifacts to catch issues before workflows fail.
Core Artifact Checks
PROJECT.md — Sections: What This Is, Requirements, Constraints, Key Decisions ROADMAP.md — Sequential phase numbers, each with Goal/Deliverables/Success Criteria STATE.md — Current Position matches ROADMAP status, reasonable progress % config.json — Valid JSON, valid enum values (mode, model_profile, depth)
Cross-Artifact Consistency
- STATE.md phase exists in ROADMAP.md
- Completed phases have matching SUMMARY files for each PLAN
- Phase directories exist for all ROADMAP phases
- No orphaned files (PLAN without phase, SUMMARY without PLAN)
Severity
| Level | Definition | Action |
|---|---|---|
| BLOCKER | Will cause workflow failure | Must fix first |
| WARNING | May cause confusion | Should fix |
| INFO | Informational | No action needed |
Common Fixes
- STATE/ROADMAP out of sync: Run /gsd:progress
- Missing SUMMARY for completed plan: Re-execute or mark incomplete
- Invalid config.json: Check for trailing commas, invalid values
- Orphaned directories: Add to ROADMAP or remove
