audit-performance
82 / 100 · Low risk
Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
By melodic-software/claude-code-plugins (GitHub) · coding · 30 stars · scanned at commit 677e798
Slowness diagnostic that never 'fixes', run before restarting or deleting: version, retention sweep, install bloat, hook/subagent fan-out, kernel-leak census. Use when: 'Claude Code is slow', 'typing lags', 'my machine freezes when Claude runs', 'why is this session sluggish', 'my hooks are slowing everything down', 'too many subagents'. Upstream bugs: /harness-ops:known-issues. Stale files: /harness-ops:audit-install-state.
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/'audit-performance' ] || [ -L ~/.agents/skills/'audit-performance' ]; then echo 'A skill folder named audit-performance 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 "$d" checkout --quiet '677e7988f432dacb5e2d4df2b124f96da8e8f9f3' -- 'plugins/harness-ops/skills/audit-performance' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/harness-ops/skills/audit-performance' ~/.agents/skills/'audit-performance' && 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/'audit-performance' ~/.claude/skills/'audit-performance' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
