95 / 100 · Low risk

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

Use liberally when you discover or are told a non-negotiable constraint — something that must always be true regardless of context. Registers the invariant so future sessions never violate it.

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/'jumbo-add-invariant' ] || [ -L ~/.agents/skills/'jumbo-add-invariant' ]; then echo 'A skill folder named jumbo-add-invariant already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jumbocontext/cli' "$d" && git -C "$d" checkout --quiet 'b476115599278e204cf41f892a11a8ec2c96f0fd' -- 'assets/skills/jumbo-add-invariant' && mkdir -p ~/.agents/skills && cp -R "$d"/'assets/skills/jumbo-add-invariant' ~/.agents/skills/'jumbo-add-invariant' && 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/'jumbo-add-invariant' ~/.claude/skills/'jumbo-add-invariant' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
