See that a few times, agent checks todo lists during a new turn even though. Todo lists can work without reads, as the tool invocation remains in context for the agent.

Right now the tool as read and write operation. With the write-only setting on, the tool would not have an operation parameter; and would only handle write.

There are open questions how clear works, or pinning todos for a workspace; but they could be auto-included in the initial user prompt if needed. For a first cut, this write-only todolist setting can ignore that.
