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

Use when a skill is brittle, drifting, repeatedly failing, or needs a Reliable Skill Contract. Trigger for phrases like skill lifeguard, reliable skill, self-maintaining skill, negative examples, verification checkpoints, drift signals, replay hooks, or failure log to skill patch. Audits or patches skills so high-value workflows include explicit forbidden behaviors, checkpoints, machine-checkable done conditions, replay or smoke hooks, and drift detection.

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/'skill-lifeguard' ] || [ -L ~/.agents/skills/'skill-lifeguard' ]; then echo 'A skill folder named skill-lifeguard already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/majiayu000/spellbook' "$d" && git -C "$d" checkout --quiet '238e07625aeca5bcf0d6f7cb3e2d07f94c717194' -- 'skills/skill-lifeguard' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/skill-lifeguard' ~/.agents/skills/'skill-lifeguard' && 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/'skill-lifeguard' ~/.claude/skills/'skill-lifeguard' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
