What this skill tells your AI

The instructions your AI receives, as published by tibsfox/gsd-skill-creator in project-claude/skills/gsd-preflight/SKILL.md and read by ahel’s review.

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

BLOCKERWill cause workflow failureMust fix first
WARNINGMay cause confusionShould fix
INFOInformationalNo 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
