caveman-learn

97 / 100 · Low risk

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

By JuliusBrussee/caveman (GitHub) · coding · 118,803 stars · scanned at commit 3dc497a

Act on a Caveman learn report - review the ranked token sinks, apply cost-lowering fixes with per-edit consent, and report what those fixes returned. Use when asked to lower an agent's token cost, what caveman has saved, to trim a heavy CLAUDE.md, or to offload re-pasted context into cavemem.

Works with any agent that supports SKILL.md skills.

if [ -e ~/.agents/skills/'caveman-learn' ] || [ -L ~/.agents/skills/'caveman-learn' ]; then echo 'A skill folder named caveman-learn already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/JuliusBrussee/caveman' "$d" && git -C "$d" checkout --quiet '3dc497a7f858c774d6e15b25e8c6120ef3a0eda8' -- 'skills/caveman-learn' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/caveman-learn' ~/.agents/skills/'caveman-learn' && 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/'caveman-learn' ~/.claude/skills/'caveman-learn' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
