By corca-ai/charness (GitHub) · coding · 11 stars · scanned at commit abdb77f

Use when creating or upgrading a repo-owned CLI, bootstrap script, or command runner. Define the command surface, install/update contract, structured output, dry-run and doctor behavior, distribution path, and quality gates before spreading ad hoc shell or Python entrypoints.

Works with any agent that supports SKILL.md skills.

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

if [ -e ~/.agents/skills/'create-cli' ] || [ -L ~/.agents/skills/'create-cli' ]; then echo 'A skill folder named create-cli already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/corca-ai/charness' "$d" && git -C "$d" checkout --quiet 'abdb77fd876eb7700c9550b0c6fcd96ee10bee84' -- 'skills/public/create-cli' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/public/create-cli' ~/.agents/skills/'create-cli' && 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/'create-cli' ~/.claude/skills/'create-cli' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
