## What it is
Clippy is the official Rust linter, a collection of over 800 lints that catch common mistakes and suggest more idiomatic code. It integrates with cargo and categorizes lints by severity and purpose, from correctness to style and performance.

## Use cases
- lint my rust code for common mistakes
- enforce idiomatic rust style in ci
- find performance issues in rust code
- catch suspicious or incorrect code patterns
- configure strict coding style rules for a rust project

## When to choose
- you write or maintain any Rust codebase
- you want automated code quality checks in CI
- you need configurable lint levels from permissive to pedantic

## When to avoid
- you are linting a non-Rust language
- you need full static type analysis or security auditing beyond linting

## Facets
- artifact type: cli-tool
- maturity: stable
- function: linter, developer-tools, code-review
- domain: developer-tools, programming-languages, testing
- platform: rust, cli, cross-platform
- tags: static-analysis, rust, code-quality, ci
