# Phase Gate Skill ## Goal Enforce state machine discipline in workflows (especially `/ship`) by validating preconditions before each phase transition. ## State Machine Definitions ### /ship Workflow States ``` PLAN → EXECUTE → LINT → REVIEW → COMMIT → DONE ``` ### Phase Transition Rules | Transition | Preconditions | Validation | |------------|---------------|------------| | **START → PLAN** | - Task description exists<br>- Architecture constraints loaded | Check `.agent/rules/architecture-design.md` exists | | **PLAN → EXECUTE** | - Implementation plan written<br>- File paths identified<br>- Architecture pre-audit passed | Verify plan file exists<br>Run `architecture-guard` audit | | **EXECUTE → LINT** | - Code files written/edited<br>- No uncommitted changes in constraints | Check files exist at planned paths<br>`git status` shows modifications | | **LINT → REVIEW** | - Linter checks passed<br>- No hardcoded secrets detected | Exit code 0 from pre-commit-check.sh<br>No security violations | | **REVIEW → COMMIT** | - Code review completed<br>- No blocking issues (❌ Must Fix) | Review report exists<br>Parse report for blocking issues | | **COMMIT → DONE** | - Changes committed<br>- Task progress updated | `git log -1` shows new commit<br>task-progress.md updated | ## When to Use Invoke this skill at **every phase transition** in `/ship` workflow: ```yaml # Example in workflows/ship.md phases: - name: PLAN agent: planner gate_check: phase-gate --from START -
