Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description must carry the full behavioral burden. It states that the tool exposes a static route table, implying a read operation, but it does not disclose output shape, ordering, pagination, or whether the result includes only active routes. For a no-parameter list tool this is minimally informative but not fully transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
