statechart
95 / 100 · Low risk
Fine to try.
By jsartisan/frontend-challenges (GitHub) · design · 90 stars · scanned at commit 630c44b
Draw how any system moves between states, such as a product flow, a protocol, or a service, as a Mermaid statechart from a TLA+ model. Each bug is a numbered path with blue borders to a state that breaks a rule. Use for /statechart, to show a bug as a path through states, or to turn an agreed chart into a TLA+ skeleton.
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/'statechart' ] || [ -L ~/.agents/skills/'statechart' ]; then echo 'A skill folder named statechart already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jsartisan/frontend-challenges' "$d" && git -C "$d" checkout --quiet '630c44b299f1467e789d561da3785cfd99247ed0' -- '.claude/skills/statechart' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/statechart' ~/.agents/skills/'statechart' && 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/'statechart' ~/.claude/skills/'statechart' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
