What version of clippy_utils does this skill support?

This skill is specifically pinned to clippy_utils 0.1.95 on rustc 1.95.0-nightly, which is essential for ensuring API compatibility.

How does it help with performance when writing lints?

It provides specific performance conventions such as pre-filtering syntactically, interning Symbols, and running suppression-zone checks after cheap matches.

Does this skill assist with UI testing for Rust lints?

Yes, it includes guidance on using the UI test harness and instructions for blessing tests using DYLINT_BLESS.

Can this skill help me find replacements for deprecated Clippy APIs?

Yes, it includes a detailed list of removed APIs like match_def_path and provides modern alternatives using DiagnosticItems, LangItems, or tcx.def_path_str.

When should I use clippy_utils instead of raw rustc APIs?

You should use clippy_utils for higher-level abstractions like type checking, trait implementation checks, and path matching, which the skill helps you choose and implement correctly.
