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

The description mentions 'Task text discarded' and some parameter descriptions note 'discarded after the call', but it does not disclose potential side effects such as external network calls, costs, or data handling. Since no annotations are provided, the description carries the full burden and is insufficient.

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 short, with only three sentences, and avoids irrelevant detail. It is front-loaded with the primary purpose, though the final sentence 'Task text discarded' is cryptic and could be clearer.

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 9 optional parameters and no output schema, the description is not complete enough for an agent to know what to pass for a given task or what 'connection methods' means. There is no mapping between example tasks (weather, search, scrape, voice) and corresponding parameters, nor any detail about expected return values.

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?

All 9 parameters have descriptions, but most are terse and focus on disposal or simple checks (e.g., 'discarded after the call', 'no disk access'). The descriptions add some context beyond raw names, but they do not explain how each parameter relates to the tool's 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 states a clear action ('Find a public pay-per-call tool gateway') and gives example task categories, but 'tool gateway' is vague and not tied to the tool's name or the concrete parameters. It does not explicitly distinguish this tool from sibling tools like weather-hint or web-fetch.

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 suggests tasks such as weather, search, scrape, or voice, but it gives no guidance on when to prefer this tool over sibling tools or when not to use it. There is no comparison, prerequisites, or selection criteria.

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