## Project history and usage

cargo-shear is a Rust Cargo subcommand for detecting and optionally fixing unused or misplaced dependencies and unlinked source files.

### Project history

The GitHub repository was created in March 2024 and the first crates.io release appeared the next day. The README describes the tool as feature-complete, with ongoing work focused on bug fixes, dependency upgrades, and UI/UX improvements.

### Adoption history

Despite being newer than the other tools in this batch, crates.io metadata showed many releases by 2026 and package facts list Homebrew, Nix, and winget packages. The README includes CI examples and machine-readable JSON output for automation.

### How it is used

Users run cargo shear to check for issues, cargo shear --fix to remove unused dependencies, --deny-warnings for strict CI, --format=json for structured output, and --expand with nightly when macro expansion is needed.

### Why package nerds care

It is part of the Rust ecosystem's dependency-hygiene tooling, sitting near cargo-udeps and cargo-machete but using rust-analyzer parsing and Cargo metadata to find unused dependencies without compiling in the default mode.

### Timeline

- 2024: Repository created and first crates.io release published.
- 2026: README described the tool as feature-complete.
- 2026: crates.io reported v1.13.1 as the latest release.
