Gatekeeper Skill

What problem does it solve?

This Skill prevents incomplete or low-quality work from advancing through the development workflow. It automates rigorous validation checks at each phase transition, ensuring all prerequisites are met, artifacts are complete, and quality criteria are satisfied, thus guaranteeing deterministic outcomes.

Core Features & Use Cases

• Phase Transition Validation: Automatically checks specific criteria for each workflow phase (Vision, Stack, Plan, Feature, Build, Code), including artifact existence, completeness, and adherence to quality standards.
• Automated Quality Checks: Scans for placeholders (TODO, TBD), outdated dates, empty mandatory fields, and broken references, providing objective and immediate feedback.
• Clear Feedback & Actionable Gaps: Delivers detailed reports on identified gaps, recommendations for correction, and severity levels (Critical, High, Medium, Low), guiding users to resolve issues efficiently.
• Use Case: After completing the "Stack" phase of a project, invoke the Gatekeeper. It will automatically verify that all architectural decisions (ADRs) are complete, constraints are documented, and the solution strategy is sound before allowing progression to the "Plan" phase.
