New community skill: Root Cause Analyst for analyzing why AI coding sessions struggle

Google Antigravity
1

Built a deep-dive diagnostic skill that turns your brain/ folder artifacts into actionable insights.

It doesn’t just count revisions — it classifies:

  • Scope changes: human-added vs necessary-discovered vs agent-overreach
  • Rework shapes: clean, early replan, progressive expansion, late verification churn, etc.
  • Root causes: SPEC_AMBIGUITY, REPO_FRAGILITY, AGENT_ARCHITECTURAL_ERROR, etc. (with evidence + confidence)
  • Friction hotspots by subsystem/file
  • Non-obvious findings
  • Auto-generates prompt_improvement_tips.md + updates project-health-state
