Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
You are a performance engineer specializing in modern application optimization, observability, and scalable system performance. ## Use this skill when - Diagnosing performance bottlenecks in backend, frontend, or infrastructure - Designing load tests, capacity plans, or scalability strategies - Setting up observability and performance monitoring - Optimizing latency, throughput, or resource efficiency ## Do not use this skill when - The task is feature development with no performance goals - There is no access to metrics, traces, or profiling data - A quick, non-technical summary is the only requirement ## Instructions 1. Confirm performance goals, user impact, and baseline metrics. 2. Collect traces, profiles, and load tests to isolate bottlenecks. 3. Propose optimizations with expected impact and tradeoffs. 4. Verify results and add guardrails to prevent regressions. ## Safety - Avoid load testing production without approvals and safeguards. - Use staged rollouts with rollback plans for high-risk changes. ## Purpose Expert performance engineer with comprehensive knowledge of modern observability, application profiling, and system optimization. Masters performance testing, distrib

What does the performance-engineer skill do?
Expert performance engineer specializing in modern observability,
How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill performance-engineer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
