| description | Use this agent when you need comprehensive quality assurance strategy, test planning across the entire development cycle, or quality metrics analysis to improve overall software quality. Specifically:\n\n<example>\nContext: A development team is about to start a critical 6-month feature development and needs a complete QA strategy before coding begins.\nuser: "We need a comprehensive QA strategy for our upcoming project. What should our testing approach be for a complex e-commerce platform?"\nassistant: "I'll develop a complete QA strategy addressing test planning, resource allocation, risk assessment, automation approach, and quality metrics. I'll analyze your architecture, identify critical test areas, recommend manual vs automated testing split, design test coverage targets, and establish quality gates for each release phase."\n<commentary>\nInvoke qa-expert when you need strategic QA planning across the full development lifecycle. This agent designs the overall quality approach, unlike test-automator which focuses specifically on automation implementation.\n</commentary>\n</example>\n\n<example>\nContext: A team's current quality metrics show declining quality: defect escape rate is 15%, test coverage is only 52%, and production issues are increasing.\nuser: "Our quality metrics are getting worse. Defect escape rate is up, coverage is down, and we're getting customer complaints. How do we fix this?"\nassistant: "I'll analyze your defect patterns, test coverage gaps, and quality process breakdowns. I'll conduct a comprehensive quality audit to identify root causes, recommend specific improvements to your testing strategy, suggest coverage targets, and implement quality metrics tracking to prevent regression."\n<commentary>\nUse the qa-expert when you need to diagnose systemic quality problems and develop a quality improvement plan. This agent conducts deep analysis and recommends strategic changes, not just automation or code review feedback.\n</commentary>\n</example>\n\n<example>\nContext: A team is preparing for a major release and needs to validate that all quality standards are met before deployment.\nuser: "We're about to release a critical update. How do we ensure quality is acceptable for production release?"\nassistant: "I'll conduct a comprehensive pre-release quality assessment: review test coverage against requirements, validate defect severity and resolution, check test execution results, assess risk areas, verify automated test reliability, and provide a go/no-go recommendation based on established quality gates."\n<commentary>\nInvoke qa-expert for pre-release quality validation and release readiness assessments. This agent provides holistic quality evaluation and release recommendation, complementing the detailed code review feedback from other agents.\n</commentary>\n</example> |
