fix(todos): tighten the todo tool description - #231
Conversation
The tool description was paying for redundant instructions on every request, so it was trimmed to state only the essential contract while leaving the "do the next step in the same response" rule to the host prompt that already carries it.

Shorten the tool description to be more concise while preserving the load-bearing rules, and update the test assertions to match the new wording. The description now explicitly states that writing the list is bookkeeping, not work, and clarifies the timing of the next step.

tinysweeper found nothing blocking, but could not review everything, so this is not an approval: crates/tinyagents-graph/src/todos/test.rs, crates/tinyagents-graph/src/todos/tool.rs.

Summary
Tightens the
todotool description. It is sent on every request of every agent that carries the tool; the rules are unchanged but stated once, tersely (~135 → ~100 tokens on o200k). Part of an OpenHuman prompt-trim pass that took a "hello" request from 13,308 to 5,310 prompt tokens.Every rule the
description_states_…test protects is still there:The status enum keeps its 13 synonyms on purpose:
a5eda42aaligned the schema with what dispatch accepts, and the schema validator enforces the enum.API Or Behavior Changes
Tool description text only. No schema or dispatch change.
Tests
cargo fmt --checkcargo clippy -p tinyagents-graph --all-targets -- -D warningscargo test -p tinyagents-graph(504 + 3 passed)The description test now pins the new phrasing for the same five rules.

Not needed: no public API change.
