cheadergen

Reference for the ui-tests infrastructure: test suites, directory layout, test.toml format, snapshot workflow, and common commands. Use when working with ui-tests cases, debugging test failures, or scaffolding new tests.

Runs the cheadergen verification workflow in stages - lint, format, generation tests, and full test suite. Use when user says "verify", "run checks", "run tests", or wants to validate changes before committing.

Guidelines for writing Rust documentation. Refer to this when you need to write doc comments on functions, types or modules.

Look up Rust dependency API docs locally. Use when the user or task requires information about a dependency's API, types, traits, functions, or modules — e.g. "look up guppy's PackageGraph", "what methods does rustdoc_types::Item have", "show me clap's derive API".

Write a test to improve code coverage. Uses `cargo llvm-cov` to identify uncovered lines, then writes a focused test to cover them. Use when user says "write test", "improve coverage", "cover lines", or "write-test".
