## Phase 2 awareness
**Phase 2 is now in progress** (started 2026-07-09). Sub-agents (`docs/phase2.md` §5) landed first: `pkg/agent.SubAgent`/`SubAgentRegistry` (`pkg/agent/subagent.go`) let a caller run a specialized, nested `agent.Loop` and get its final response back — the harness uses this for its `delegate` tool (builder/planner). MCP server/client, full RAG pipeline with Qdrant/sqlite-vec backends, skills system, and observability remain unimplemented; don't start those unless explicitly asked. Reference `docs/phase2.md` for spec when needed.
Phase 2 features (MCP server/client, full RAG pipeline with Qdrant/sqlite-vec backends, skills system, sub-agents, observability) are planned but not in scope for initial implementation. Do not start implementing phase 2 code unless explicitly asked. Reference `docs/phase2.md` for spec when needed.

> ✅ **Implemented** (2026-07-09): `pkg/agent/subagent.go` has `SubAgent` (Name, Description, Persona, Tools, MaxIterations) and `SubAgentRegistry`, matching §5.1–5.3 below. `SubAgent.Run` builds the nested `agent.Config` and calls `Loop.Run` — no `Approver`/`Sandbox` is set on it, so a single `Ask` approval on the caller's delegate-style tool covers the whole nested run (Ask-gated tools execute unprompted when `Config.Approver` is nil — see `pkg/agent/loop.go`'s `executeTool`). The `Model` field and `DefaultSubAgents`/registry-building code below are illustrative; `rony-harness` builds its own two sub-agents (`builder`, `planner`) instead — see `rony-harness/TODO.md` §2 and `internal/cli/delegate_tool.go` there.
