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

With no annotations, the description discloses some behavior: it returns connection methods and discards task text. It does not state whether it performs network calls, has side effects, or requires authentication, leaving important behavioral details implicit.

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, starts with the action, and includes examples plus a behavior note. No filler or redundant detail.

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 and no output schema, the description is too thin to let an agent know what to pass or what 'connection methods' will look like. It does not explain which parameters are relevant for which task category, so the context is incomplete.

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 schema description, so the baseline is 3, and the task examples provide some context for params like city, query, and url. The tool description does not explicitly map each parameter to a gateway category, but it does not contradict 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?

States a clear mission: find a public pay-per-call tool gateway for example tasks and return connection methods. It distinguishes itself from data-fetching siblings by emphasizing connection methods, though 'tool gateway' remains somewhat abstract.

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 example tasks (weather, search, scrape, voice) imply the intended use, and 'Task text discarded' warns not to rely on free-form task text. It does not explicitly name sibling alternatives or say when not to use this tool.

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