uv/CLAUDE.md

• Read CONTRIBUTING.md for guidelines on how to run tools
• ALWAYS attempt to add a test case for changed behavior
• PREFER integration tests, e.g., at it/... over unit tests
• When making changes for Windows from Unix, use cargo xwin clippy to check compilation
• NEVER perform builds with the release profile, unless asked or reproducing performance issues
• PREFER running specific tests over running the entire test suite
• AVOID using panic!, unreachable!, .unwrap(), unsafe code, and clippy rule ignores
• PREFER patterns like if let to handle fallibility
• ALWAYS write SAFETY comments following our usual style when writing unsafe code
• PREFER #[expect()] over [allow()] if clippy must be disabled
• PREFER let chains (if let combined with &&) over nested if let statements
• NEVER update all dependencies in the lockfile and ALWAYS use cargo update --precise to make lockfile changes
