What problem does it solve?
This Skill solves the common issue of teams advancing to the next implementation phase before confirming the current phase is fully complete, which leads to accumulated technical debt, missed deliverables, and unexpected quality issues in production.
Core Features & Use Cases
- Parallel Scope & Quality Analysis: Runs simultaneous scope completion checks and full quality gate suites (linting, type checking, test coverage, security scans, smoke tests) to get a comprehensive view of phase status in one step.
- Flexible Validation Modes: Supports full phase evaluation, mid-phase progress checks, and pre-implementation plan validation to fit different points in the development workflow.
- Controlled Phase Transitions: Enforces explicit user approval before moving to the next phase, and integrates with git worktree and PR workflows to streamline handoffs.
- Use Case: A development team building a customer portal in 6 phased increments can use this skill to confirm Phase 2 (user profile management) has all deliverables complete, all tests pass with 90%+ coverage, and no unplanned scope creep before starting work on Phase 3 (order history).
Quick Start
Use the phase-gate skill to check if Phase 4 of the e-commerce implementation is ready to move to the next phase.
