Profile-driven performance optimization of mecatl using the offline benchmark + scenario harness. Use when optimizing allocations or latency, reducing allocs/op or memory, profiling a Go benchmark, pinpointing a hotspot with pprof, proving a win with benchstat, adding a regression benchmark, wiring profile-guided optimization (PGO), or investigating "why is this slow / allocating" or a suspected perf regression. Covers task bench, task perf:scenarios, memprofile -> pprof, benchstat A/B, allocs-…

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/'perf-optimization' ] || [ -L ~/.agents/skills/'perf-optimization' ]; then echo 'A skill folder named perf-optimization already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/stacklok/mecatl' "$d" && git -C "$d" checkout --quiet 'aa9f24acdd60db26879863ec0a2aa7bf238d72ff' -- '.claude/skills/perf-optimization' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/perf-optimization' ~/.agents/skills/'perf-optimization' && 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/'perf-optimization' ~/.claude/skills/'perf-optimization' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
