What problem does it solve? After writing code, it is easy to miss spec violations, broken tests, leftover debug logging, 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 reach the repository. ## Core Features & Use Cases - Spec Compliance Review: Reads the applicable .trellis/spec/ package and layer indexes and checks changed code against their Quality Check guidelines. - Project Checks: Runs the project's lint, type-check, and test commands and requires failures to be fixed before proceeding. - Cross-Layer Analysis: Traces data flow (Storage → Service → API → UI), checks code reuse, import paths, circular dependencies, and same-layer consistency for multi-layer changes. - Use Case: After implementing a feature spanning the API and UI layers, run this check before committing to confirm tests pass, types align across layers, and the spec docs are updated with any lessons learned. ## Quick Start Ask the assistant to run the trellis quality check on the current uncommitted changes and fix any violations it finds.
