Runs an autonomous review-and-fix improvement loop over a Claude Code skill until a review comes back clean, with a cross-round findings ledger, escalation when fixes stop converging, and a mechanical scope guard. Reviews are performed by the plugin-dev skill-reviewer agent. Use to fix skill quality issues, iteratively refine a skill, or resume a loop after an escalation ('fix my skill', 'improve this skill until it passes review', 'skill improvement loop'). NOT for a one-time review — use the …

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'skill-improver' ] || [ -L ~/.agents/skills/'skill-improver' ]; then echo 'A skill folder named skill-improver already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/trailofbits/skills' "$d" && git -C "$d" checkout --quiet 'e4dd0bb5b15535f7c5a0834187dffba6ac37e4ff' -- 'plugins/code-improver/skills/skill-improver' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/code-improver/skills/skill-improver' ~/.agents/skills/'skill-improver' && 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/'skill-improver' ~/.claude/skills/'skill-improver' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
