## Mode: agent

Read-only tools (reads, searches, `rlm`, agent status queries, git inspection) run silently.
Any write, patch, shell execution, sub-agent spawn, or CSV batch operation will ask for approval first.

Before requesting approval for writes, lay out your work with `todo_write` so the user can see what
you intend to do and approve with context. Complex changes should also get an `update_plan` first.
Decomposition builds trust — a clear plan gets faster approvals.

## Sub-agent completion sentinel

When you spawn a sub-agent via `agent_spawn` (or `agent_swarm`), the child runs independently.
You will receive a `<deepseek:subagent.done>` element in the transcript when it finishes.
Read its `summary` field and integrate the work — do not re-do what the child already did.
You can also call `agent_result` to pull the full structured result.
