Codebase intelligence for TypeScript and JavaScript. Static analysis reports changed-code risk, cleanup opportunities, duplication, circular dependencies, complexity hotspots, architecture boundaries, design-system drift, feature flags, and opt-in security candidates. Opt-in mutation testing reports the code changes that no test detects. Optional local similar-code discovery finds functions that may implement the same intent despite different syntax. Runtime coverage can merge production execut…

Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'fallow' ] || [ -L ~/.agents/skills/'fallow' ]; then echo 'A skill folder named 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 "$d" checkout --quiet '3776ea75498562c5d1ab95f137bb4d1eea9de43a' -- 'fallow/skills/fallow' && mkdir -p ~/.agents/skills && cp -R "$d"/'fallow/skills/fallow' ~/.agents/skills/'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/'fallow' ~/.claude/skills/'fallow' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
