Feature Validate Skill

Run comprehensive quality gates on the implemented feature. Phase 4 of the feature lifecycle (design → plan → implement → validate → release).

Instructions

Phase 0: PRIME

1. Read and follow the repository CLAUDE.md before any other action — it may override defaults for linting, test commands, or gate criteria.
2. Verify feature state is validate and implement is completed. All state operations go through python3 ~/.claude/scripts/feature-state.py — never modify state files directly.
3. Load implementation artifact from .feature/state/implement/. Validation cannot proceed without implementation artifacts; if missing, stop and report.
4. Load L0, L1, and implementation context so quality gates run against the correct scope.

Gate: Implementation artifact loaded. Feature state confirms implement completed. Proceed.
