 ### Agent Layer (Phase 1 completed)
 - AsyncGenerator-based agent loop (best pattern from Claude Code)
-- `@claude-code-kit/types` package for pure interfaces (prevents cascading breaking changes)
 - Provider adapters: AnthropicProvider, OpenAIProvider (with baseURL for Ollama/vLLM)
 - Tool interface: Zod schema + execute function, no UI rendering
 - Permission: tiered model (alwaysAllow list + sessionApprove + per-call callback)
