Understand, modify, debug, and extend the workflow execution engine. Use for: executor architecture, block handlers, dependency-layer scheduling, input resolver syntax, loops/parallels/routing flow, streaming execution, ExecutionContext contracts, and adding handlers safely with tests.

Build, modify, and debug API routes and authentication flows. Use for: creating Next.js API routes, better-auth setup, OAuth integration, Zod validation, session management, middleware, CORS, rate limiting, webhook trigger endpoints, chat/public API auth, dual auth (session + workflow), and internal x-api-key auth.

Optimize execution speed, database queries, and frontend rendering. Use for: executor layer/stream performance, pgvector HNSW tuning, knowledge/image search strategy, React Flow render optimization, Zustand selector patterns, Next.js bundle tuning, and mandatory performance regression testing.

Work with Socket.IO collaboration and Zustand state in Zelaxy. Use for: socket token auth, workflow/workspace rooms, operation queue retries, presence/cursor sync, workflow rehydration, history middleware, and SSR-safe persisted stores.

Maintain and improve security across the Zelaxy platform. Use for: secret encryption boundaries, auth modes (session/API key/internal JWT/cron), CSP and middleware hardening, webhook verification, tenant isolation, and security test coverage.

Write, review, and debug tests using Vitest. Use for: unit tests, API route tests, executor/serializer/tool tests, jsdom vs node environment selection, shared __test-utils__ patterns, and mandatory code-to-test sync with executed test runs.

Build, modify, and style UI components. Use for: shadcn/ui primitives, Tailwind token theming, arena and landing theme providers, React Flow workflow nodes/edges, workflow sub-block renderer components, CSS modules where used, and Zustand-driven UI state.

Understand, modify, debug, and extend the workflow execution engine. Use for: executor architecture, block handlers, dependency-layer scheduling, input resolver syntax, loops/parallels/routing flow, streaming execution, ExecutionContext contracts, and adding handlers safely with tests.
