launch_turtlesim

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

Without annotations, the description carries the burden; it states the tool launches a GUI and involves a WebSocket server, but does not disclose details like blocking behavior, resource requirements, or side effects. It is adequate but minimal.

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 short but the second sentence is redundant ('Example: Launch turtlesim for turtle simulation' essentially repeats the first sentence). It could be more concise and front-loaded.

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?

For a simple, parameterless tool, the description is sufficiently complete. It states the purpose and the mechanism (WebSocket server). No output schema exists, but the simplicity does not require further detail.

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?

With zero parameters and 100% schema coverage, the description adds no parameter info, but the baseline is 4 according to the rubric. The example provides no additional semantic meaning, but none is needed.

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 launches the turtlesim GUI application via a WebSocket server, specifying the resource (turtlesim) and the action (launch). It distinguishes from sibling tools like launch_rviz or launch_gazebo which launch different GUIs.

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 description implies usage for starting the turtle simulation but provides no explicit guidance on when to use this tool versus alternatives, nor any prerequisites or conditions.

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