generate_ros_graph

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

No annotations are present, so the description carries the full burden. It only states the core action without disclosing any behavioral traits such as whether it launches a GUI, writes output files, or has blocking behavior. This is insufficient for a tool with no structured metadata.

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 entire description is a single sentence with no redundant words, efficiently conveying the tool's primary function. It is appropriately front-loaded and compact.

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 simplicity (one optional parameter, no output schema), the description adequately covers the basic action. However, the absence of behavioral details and usage context leaves gaps, making it minimally viable but not comprehensive.

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 sole parameter output_format is fully documented in the schema with an enum and default, providing complete semantic coverage. The description adds no additional parameter context, but the schema already provides the necessary details, aligning with the baseline score.

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 uses a specific verb 'Generate' and identifies the resource as 'RQT graph' showing node-topic connections, making its purpose clear. However, it does not differentiate itself from sibling tools like get_node_connections or list_ros_topics.

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 the tool is for visual graph generation but provides no explicit guidance on when to choose it over alternatives such as get_node_connections or list_ros_nodes. There is no mention of exclusions or alternative tools.

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