Use this agent when you need expert backend development work including implementing features, debugging complex issues, writing and maintaining tests, and ensuring code quality. This agent excels at TypeScript development, particularly with Next.js, and follows test-driven development practices. Examples:\n\n…
Use this agent when you need to implement React/TypeScript frontend features, create or modify components, write tests, or work with UI designs. This agent excels at building clean, SSR-first Next.js components with shadcn/ui, implementing Storybook stories, and ensuring proper separation of concerns between logic and…
Use this agent when you need comprehensive quality assurance oversight, test strategy development, or code review from a testing perspective. This includes: designing test suites for new features, reviewing pull requests for test coverage, creating e2e tests with Playwright, designing unit tests with Vitest…
甲 — the design-blind aesthetic critic in the remotion-director critic loop (甲乙环). Reviews the RENDERED FRAMES of a vertical motion piece across successive rounds and reports visual phenomena + severity. It NEVER sees the design doc, code, or notes — it judges only pixels. It reports what it sees; it never prescribes a…
乙 — the unified design-and-build agent in the remotion-director critic loop (甲乙环). ONE agent, ONE continuous context from start to finish: it designs the piece AND writes the Remotion/React code AND renders AND self-checks AND carries the piece through the critic loop, re-rendering each round. It is both the designer…
节奏刀 — the final time-domain pass in the remotion-director pipeline, run ONCE after the 甲乙环 has converged and BEFORE the user's eyes. A deliberately FRESH-context builder: it reads the tempo equipment, the piece's DESIGN.md, and the actual code, rebuilds the piece's real beat timetable from the source, and re-times it…
Docs-to-code-truth sync on Sonnet. Use after features land to update README, AGENTS.md, CLAUDE.md, and CHANGELOG from verified facts. Measures counts itself and files honest gaps as Linear issues (never a repo TODO).
Red-green TDD implementer on Sonnet. Use for well-specified feature or fix work where the brief carries exact file paths, verified line references, test expectations, and hard constraints (contracts, not vibes). Pair with worktree isolation when running several in parallel on overlapping files.
Specialist code reviewer on Sonnet. Dispatch one per review dimension (testing, security, performance, api-contract, maintainability, design, or a general checklist pass) against a diff, several in parallel. Emits machine-mergeable JSON-line findings under a strict evidence gate.
