What problem does it solve? After writing code, it is easy to miss spec violations, broken tests, or inconsistencies across layers before committing. This Skill runs a structured quality verification pass over recently changed code so defects and context drift are caught before they land in the repository. ## Core Features & Use Cases - Spec Compliance Review: Reads task artifacts (prd.md, design.md, implement.md) and per-layer spec indexes to verify the implementation matches documented conventions. - Project Check Execution: Runs the project's lint, type-check, and test commands and requires failures to be fixed before proceeding. - Cross-Layer Checklists: Covers data flow across Storage/Service/API/UI layers, code reuse, import/dependency correctness, and same-layer consistency. - Use Case: Before committing a feature that touches the API and UI layers, run this Skill to confirm tests pass, types align across layers, and any lessons learned are written back into the spec docs. ## Quick Start Ask the AI to run the trellis-check quality verification on the code changes you just made before committing them.
