  "github_readme_excerpt": "# Cargo Shear \u2702\ufe0f \ud83d\udc11\n\nDetect and fix issues in Rust projects:\n\n- **Unused dependencies** in `Cargo.toml`\n- **Misplaced dependencies** (dev/build dependencies in wrong sections)\n- **Unlinked source files** (Rust files not reachable from any module tree)\n\n\u003e [!NOTE]\n\u003e This tool is considered feature-complete. We continue to welcome contributions that focus on bug fixes, dependency upgrades, and UI/UX improvements.\n\n## Installation\n\n```bash\n# Install from pre-built binaries.\ncargo binstall cargo-shear\n\n# Build from source.\ncargo install cargo-shear\n\n# Install from brew.\nbrew install cargo-shear\n```\n\n## Usage\n\nCheck for issues without making changes:\n\n```bash\ncargo shear\n```\n\nAutomatically fix unused dependencies:\n\n```bash\ncargo shear --fix\n```\n\nTreat warnings as errors (exit with failure code):\n\n```bash\ncargo shear --deny-warnings\n```\n\nThis is useful for CI/CD pipelines to enforce strict checking of warnings such as empty files, unlinked files, and unused optional dependencies.\n\nGenerate machine-readable JSON output:\n\n```bash\ncargo shear --format=json\n```\n\nThis is particularly useful for CI/CD pipelines and custom tooling that need to programmatically process the results.\n\nDetect mismatches between `[lib]` target settings and source content:\n\n```bash\ncargo shear --check-test-targets\n```\n\nWhen set, cargo-shear warns when `test = false` is paired with source that contains tests (or `doctest = false` with source that contains doc tests), and \u2014 within a workspace \u2014 when `test` / `doctest` are left at their default of `true` for lib targets that contain none. Disabled by default; pair with `--fix` to automatically reconcile the flags.\n\n## Limitations\n\n\u003e [!IMPORTANT]\n\u003e `cargo shear` cannot detect \"hidden\" imports from macro expansions without the `--expand` flag (nightly only).\n\u003e This is because `cargo shear` uses rust-analyzer\u0027s parser to parse files and does not expand macros by default.\n\nTo expand macros:\n\n```bash\ncargo shear --expand --fix\n```\n\nThe `--expand` flag uses `car",
