## Summary

Added MCP registration and channel tool definitions with in-memory transport tests for SDK call wiring.

**Approach:** Standard approach

---

## Key Decisions

### Used MCP in-memory transport in vitest to validate tool registration and SDK call wiring
- **Chose:** Used MCP in-memory transport in vitest to validate tool registration and SDK call wiring
- **Reasoning:** Matches how MCP tools are invoked in practice and verifies the registerTool handlers end-to-end without network.

### Printed workspace responses as JSON and agent list as tab-separated table
- **Chose:** Printed workspace responses as JSON and agent list as tab-separated table
- **Reasoning:** Keeps output deterministic for tests and easy to pipe/parse
