ast-grep

95 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

By xdg/xdg-claude (GitHub) · coding · 20 stars · scanned at commit 2f3f8be

Structural code search and refactoring via ast-grep. Reach for this when Edit fails with "old_string not unique", when refactoring across formatting variations, or when matching code shape rather than text.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'ast-grep' ] || [ -L ~/.agents/skills/'ast-grep' ]; then echo 'A skill folder named ast-grep already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/xdg/xdg-claude' "$d" && git -C "$d" checkout --quiet '2f3f8be74679e47e12780341b6f79034a6317d39' -- 'context-efficient-tools/skills/ast-grep' && mkdir -p ~/.agents/skills && cp -R "$d"/'context-efficient-tools/skills/ast-grep' ~/.agents/skills/'ast-grep' && 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/'ast-grep' ~/.claude/skills/'ast-grep' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
