cargo-fallow
80 / 100 · Low risk
Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
Codebase analysis for Rust workspaces with `cargo fallow`. Finds unused dependencies, unused source files, `pub` items that can be private, boundary violations, large files and functions, complex functions, duplicated code and public API changes, and runs mutation testing. Use when asked to audit a Rust workspace or a Rust change before a commit or a PR, find unused dependencies or dead code in Rust, narrow visibility, check crate boundaries, detect duplication, gate CI, or run cargo fallow.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'cargo-fallow' ] || [ -L ~/.agents/skills/'cargo-fallow' ]; then echo 'A skill folder named cargo-fallow already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/fallow-rs/fallow-skills' "$d" && git -C "$d" checkout --quiet '3776ea75498562c5d1ab95f137bb4d1eea9de43a' -- 'fallow/skills/cargo-fallow' && mkdir -p ~/.agents/skills && cp -R "$d"/'fallow/skills/cargo-fallow' ~/.agents/skills/'cargo-fallow' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'cargo-fallow' ~/.claude/skills/'cargo-fallow' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
