snapshot
95 / 100 · Low risk
Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
Capture a baseline or post-change snapshot with the host qualified first: refuse a wall-clock claim from a bimodal-contention host and name the drift-immune counter instead. Interleaves before/after arms in one run. Use when: 'capture a baseline', 'take a post snapshot', 'run the A/B', 'can I even measure here'. Runs after /performance:goal; hands off to /performance:verify. Skip when no goal with a computed floor exists, or when the claim is code shape (/verification:measure).

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'snapshot' ] || [ -L ~/.agents/skills/'snapshot' ]; then echo 'A skill folder named snapshot already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/melodic-software/claude-code-plugins' "$d" && git -C "$d" checkout --quiet '677e7988f432dacb5e2d4df2b124f96da8e8f9f3' -- 'plugins/performance/skills/snapshot' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/performance/skills/snapshot' ~/.agents/skills/'snapshot' && 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/'snapshot' ~/.claude/skills/'snapshot' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
