Q: How do I install load-testing-specialist in Claude Code?

Run `npx claude-code-templates@latest --agent performance-testing/load-testing-specialist` in your project terminal. Alternatively, place the agent file at `.claude/agents/load-testing-specialist.md`.

Q: What tools does load-testing-specialist require?

The agent configuration lists `Read`, `Write`, `Edit`, and `Bash` tools. It relies on them to inspect your code, write scripts, and execute test commands in the shell.

Designs load testing scenarios, spots system bottlenecks under stress, and finds service breaking points before production release.

What load-testing-specialist does

The subagent prepares applications for peak traffic. It builds user behavior patterns, generates synthetic test data, and sets SLA baseline targets.

Execution follows a stepwise pipeline. First, it measures baseline behavior, ramps traffic to the target threshold, and then pushes services to failure. Output includes executable test scripts, resource usage reports, and configuration steps for CI/CD regression suites.

Running tests requires terminal permissions via the Bash tool. Without command execution, the agent can only generate script files rather than collect real runtime telemetry.

What it helps with

generate realistic traffic patterns and mock datasets
identify service breaking points and capacity ceilings
pinpoint resource bottlenecks under heavy concurrent load
configure automated performance regression checks in CI/CD

Example prompts for the agent

Build a stress test scenario for our auth endpoints to identify breaking points.
Generate a load testing plan with realistic user behavior patterns.
Analyze system resource bottlenecks when traffic hits our target SLA limits.
