What problem does it solve?
It ensures a codebase still behaves correctly after autonomous changes by running verification checks and re-validating documented behavior anchors.
Core Features & Use Cases
- Project-type detection: Reads CLAUDE.md for test/verify commands and falls back to scanning common build/test indicators.
- Test, compile, and smoke verification: Runs an appropriate test suite (with timeouts), compile/type checks, and optional verify commands.
- Behavior anchor validation: Re-checks feature anchors defined in CLAUDE.md, marking items unverifiable when they require unavailable external dependencies.
- Optional frontend UI interaction: For web-fullstack projects with Playwright MCP tools, it performs limited page navigation and interaction checks.
Quick Start
Ask your autonomous loop to run the verify skill after it finishes coding iterations to confirm tests, builds, and behavior anchors still pass.
