agent-performance-engineer — Claude Code skill: profiling
Turns your agent into a performance engineer: finds bottlenecks, runs load tests, checks scalability. Useful when an app is slow and the cause isn't obvious.
npx skills add Tony363/SuperClaude --skill agent-performance-engineer -a claude-codeWhat agent-performance-engineer does
This is a subagent with the role of a senior performance engineer. It handles application profiling, load testing, database optimization and infrastructure tuning, and sits in the Quality & Security domain.
Listed tools are Read and Grep plus jmeter, gatling, locust and newrelic. For real measurements those utilities have to be present in your project or environment — the skill does not ship them. The workflow goes from establishing baselines, to systematically locating bottlenecks, to running load tests and confirming scalability still holds. You get measurements instead of guesses.
It also coordinates with other agents, sharing domain expertise and taking part in quality validation. If there is no profiler or load tool anywhere in the project, value drops fast — you will have to set one up first.
What it helps with
- find the bottleneck in a slow endpoint
- establish performance baselines before optimizing
- run a load test and interpret the results
- verify that an optimization didn't break scalability
- cut resource usage in an app or database
Example prompts for the agent
- profile this endpoint and show me where the time goes
- draft a load test plan for the API with locust
- check whether the service survives three times the traffic
