ensure_infrastructure

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

No annotations are provided, and the description does not disclose whether this tool modifies system state, whether confirmation is required (despite the confirm_token parameter), or what happens if the services are already running or missing. The description only states the end goal, leaving the behavioral details opaque.

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 concise sentence with no unnecessary words. It communicates the core purpose efficiently and is well-structured.

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 that there are two parameters and an output schema, the description is too minimal. It lacks information about when to use the tool, how to interpret or set the parameters, and what behavioral outcomes to expect. It provides only a high-level overview.

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?

The schema has zero description coverage for parameters, and the description does not explain the purpose of confirm_token or target_services. It only mentions rosapi and rosbridge, which likely relate to target_services but this connection is not explicitly stated.

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 what the tool does: it ensures essential infrastructure services (specifically rosapi and rosbridge) are running on the target. The verb 'ensure' is action-oriented and the resource is specific, distinguishing it from sibling tools like list_topics or launch.

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?

The phrase 'Ensure ... are running' implies this should be run as a prerequisite before relying on those services. However, no explicit guidance is given about when to use it versus alternatives, or any prerequisites or exclusions, so the usage context is only implied.

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