## Capabilities

- Generate k6 load test scripts
- Locust test generation
- Gatling scenario creation
- Test scenario from OpenAPI spec
- Ramp-up/ramp-down patterns
- Think time configuration
- Virtual user modeling
- Threshold configuration

## Target Processes

- performance-optimization
- resilience-patterns
- migration-strategy
