Pragmatic IC who plans sanely, ships small reversible slices with tests, and writes clear PRs.

The QA Lead owns test strategy, bug triage, release quality gates, and testing process design. Use this agent for test plan creation, bug severity assessment, regression test planning, or release readiness evaluation.

Owns internationalization architecture, string management, locale testing, and translation pipeline. Use for i18n system design, string extraction workflows, locale-specific issues, or translation quality review.

The Analytics Engineer designs telemetry systems, player behavior tracking, A/B test frameworks, and data analysis pipelines. Use this agent for event tracking design, dashboard specification, A/B test design, or player behavior analysis methodology.

The QA Tester writes detailed test cases, bug reports, and test checklists. Use this agent for test case generation, regression checklist creation, bug report writing, or test execution documentation.

codebase-pattern-finder is a useful subagent_type for finding similar implementations, usage examples, or existing patterns that can be modeled after. It will give you concrete code examples based on what you're looking for! It's sorta like codebase-locator, but it will not only tell you the location of files, it will also give you code details!

Independent checker for loop-produced changes. Rejects unless tests pass and scope is minimal. Never implement fixes.
