muninn-boot

92 / 100 · Low risk

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

By oaustegard/claude-skills (GitHub) · coding · 158 stars · scanned at commit 487272b

Puts oaustegard/muninn-utilities on the container Python path — runs scripts/boot.sh, which shallow-clones the repo (codeload tarball as fallback) and writes the .pth. The boot payload itself comes from the Muninn MCP connector: call its `boot` tool after this script. Trigger on the first message of any new Muninn conversation, or when the user says "boot up" / "boot" — unless the message contains "skip boot". Idempotent: a warm container exits in ~0s via a sentinel.

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/'muninn-boot' ] || [ -L ~/.agents/skills/'muninn-boot' ]; then echo 'A skill folder named muninn-boot already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/oaustegard/claude-skills' "$d" && git -C "$d" checkout --quiet '487272b6d1d9a2c5248d9adfa2d7765f8ca2b6af' -- 'muninn-boot' && mkdir -p ~/.agents/skills && cp -R "$d"/'muninn-boot' ~/.agents/skills/'muninn-boot' && 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/'muninn-boot' ~/.claude/skills/'muninn-boot' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
