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

The description discloses that some inputs are 'discarded' and that 'no disk access' occurs, but it does not state side effects, error behavior, return format, or pricing implications despite calling the service 'pay-per-call'. There are no annotations to compensate for these missing behavioral details.

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 brief and contains no redundant filler. The one-sentence overview is front-loaded with the main action, and the parameter list is compact. It loses a point because the concluding sentence 'Task text discarded' is both confusing and unnecessary.

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?

With nine optional parameters, no output schema, and no annotations, the tool description is far from sufficient for an agent to understand its full behavior. The description does not explain how the parameters relate to the returned 'connection methods' or what a successful response looks like. It also omits error cases, cost details, and any expected input format.

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?

Every parameter has a description, but the semantics are unclear and internally inconsistent. For example, 'query: Search text; discarded after the length check' suggests the value only affects a length check, while 'url: HTTPS URL to normalize or cite' mixes normalization with citation without explaining the result. The descriptions do not connect parameters to the tool's stated purpose of finding a gateway.

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 names a verb ('Find') and an object ('a public pay-per-call tool gateway') but leaves the actual behavior vague. Phrases like 'for a task such as weather, search, scrape, or voice' and 'Returns connection methods' do not clarify what the tool does or how it selects a gateway. The final sentence 'Task text discarded' adds confusion because no task-text parameter is defined.

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?

There is no guidance about when to use this tool versus any of the 26 sibling tools. The description does not mention prerequisites, fallback scenarios, or intended contexts. It also fails to explain how to pick between this and similarly named tools.

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