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

With no annotations, the description must carry behavioral details. It discloses 'pay-per-call', that it returns connection methods, and that task text is discarded, but it does not explain side effects, error behavior, or whether network requests are made.

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 very short and to the point, with no redundant words or filler. It fronts the purpose and gives a concise output note.

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?

The description lacks essential context: how to invoke it with the optional parameters, what the connection methods look like, and what happens when no matching gateway is found. The schema helps but the overall tool behavior remains underspecified.

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 descriptions cover all 9 optional parameters, so the baseline is 3. The tool description adds no parameter-level information beyond what the schema already states.

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 states a clear verb ('Find') and object ('public pay-per-call tool gateway') with example tasks, but the term 'tool gateway' is vague and it is not clear what the returned 'connection methods' represent.

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?

It gives example tasks ('weather, search, scrape, or voice') but does not specify when to choose this tool over the many sibling tools or mention any alternative. No explicit when-to-use or when-not-to-use guidance.

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