The list belongs to the ONE agent session that called the tool. There is no subagent/shared/swarm scope: a non-agent caller (no `exec.agent`) has nowhere to write the list and is rejected. This is a deliberate scope limit — see the RFC.

### Tool schema
**What the model sees**: The model sees the generated [`todo_write` schema](../../../docs/tool-catalog.md#deepseek-aidsh-tool-todo).
#### What the model sees
**Token effect**: Fixed schema cost on every request where the tool is visible.
The model sees the generated [`todo_write` schema](../../../docs/tool-catalog.md#deepseek-aidsh-tool-todo).
#### Token effect
Fixed schema cost on every request where the tool is visible.
#### KV Cache effect
Prefix-stable while the definition and visibility are unchanged. Plugin lifecycle or scoped restrictions may invalidate reuse from this schema.
### Tool-call history and result
**What the model sees**: Each assistant tool call retains the entire replacement list in its arguments. Success returns exactly `Updated todo list: <pending> pending, <inProgress> in progress, <completed> completed.` Stable failures are ``Error: invalid todo: `content` must be a non-empty string``, `Error: invalid todos: duplicate content "<content>"`, `Error: invalid todos: at most one task may be in_progress, got <count>`, and `Error: todo_write requires an owning agent session`. The full `todo/write` session event is UI and replay state, not a second model message.
#### What the model sees
**Token effect**: Token growth scales with every full list the model submits, and those call arguments remain until compaction. The result itself is small and fixed-shape.

#### KV Cache effect
Append-only; newly visible content follows the reusable request prefix and does not invalidate existing KV-cache entries.
