95 / 100 · Low risk

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

Retrospective on one coding session that proposes changes to the agent's environment (hooks, checks, steering files, tool access) and files each as an ax proposal. Reads the raw session log through a bundled ledger script, with ax as the second source and the ledger. Triggers when the user says "environment retro", "env retro", "what should I change in my setup after this session", "retro this session's tooling", or invokes /ax:tune. Use /ax:retro to triage the proposals it files.

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/'tune' ] || [ -L ~/.agents/skills/'tune' ]; then echo 'A skill folder named tune already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Necmttn/ax' "$d" && git -C "$d" checkout --quiet 'fca259c0f7accfdac756ac323924bde8732fd9c0' -- 'skills/tune' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/tune' ~/.agents/skills/'tune' && 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/'tune' ~/.claude/skills/'tune' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
