history

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.

security posture

No protected-tool coverage found yet

No matching local secret-handling manifest was found for cargo-shear. Nucleus package metadata is still published here so future coverage has a stable package URL.

Install behavior

No Homebrew post-install hook is recorded in formula metadata.
Homebrew bottle metadata is available for 6 platform targets.
Build metadata lists 1 build dependencies.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.

local files

Configuration and credential file locations

These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval.
