# `ExAthena.Tools.TodoWrite`
[🔗](https://github.com/udin-io/ex_athena/blob/v0.7.1/lib/ex_athena/tools/todo_write.ex#L1)

Writes the agent's todo list.

Stored in `ctx.assigns[:todos]` by default; callers that want a different
side channel (e.g. broadcasting to a LiveView) can override via
`ctx.assigns[:todo_writer]` — a function `(list -> :ok)` that the tool
will call instead of (or in addition to) mutating the assigns map.

Arguments:

  * `todos` (required) — list of `%{content: String.t(), status: "pending"|"in_progress"|"completed"}`.

The loop replays the new list back to the model so it has fresh state.
