Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions using a 'pure Rosbridge WebSocket API' and 'safety throttling', but does not clarify whether the operation is read-only, how throttling behaves, or any side effects. This is minimal behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence that efficiently communicates the primary action. It avoids unnecessary words, though it could incorporate a bit more detail without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's three parameters and the presence of similar tools like capture_topic_sync, the description is too sparse. It does not explain how throttling works, what the defaults represent, or when to choose this over alternatives, leaving a significant contextual gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description does not explain any of the three parameters (topic, duration_sec, max_messages). Their semantics are entirely unspecified in both the schema and description, leaving the agent without crucial information for correct invocation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool samples ROS topic messages using a specific verb and resource. It mentions 'safety throttling' as a distinguishing feature, though it does not explicitly compare to similar tools like capture_topic_sync.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance is given on when to use this tool versus alternatives. The phrase 'safety throttling' vaguely implies a use case for controlling message rate, but there are no clear contextual cues or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
