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

With no annotations, the description carries the burden. It discloses that task text and several parameters are discarded, and explicitly notes 'no disk access' for the path parameter. However, it omits details on side effects, rate limits, or the exact nature of 'connection methods,' so transparency is partial.

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 two sentences, front-loading the primary purpose and return type. It is concise and free of fluff, though it could benefit from a hint on parameter selection.

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 tool with 9 parameters and no output schema, the description is insufficiently complete. It does not explain how parameters relate to the requested task, which parameters to supply for a given gateway, or what the connection methods look like. An agent would struggle to invoke it correctly without more guidance.

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 coverage is 100%, so the schema already documents all parameters. The description adds only task examples (weather, search, scrape, voice) without mapping them to specific parameters, providing minimal additional semantic value beyond the schema.

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 a specific action (find a gateway) and its purpose (for tasks like weather, search, scrape, voice), and notes the return type (connection methods). However, it does not explicitly differentiate from sibling tools, though its meta-tool nature is implicit.

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 provides examples of tasks but no guidance on when to use this tool over siblings, nor any conditions or exclusions. There is no mention of alternatives or when not to use it, leaving usage largely to inference.

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