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

With no annotations, the description carries the burden of behavioral disclosure. It usefully states that task text is discarded and that the tool returns connection methods, implying a read-only, privacy-conscious lookup. It does not, however, disclose cost implications, network side effects, or the structure of returned connection methods.

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, front-loaded with the core purpose, and every sentence earns its place: what it finds, what it returns, and what is discarded. No filler or redundant text.

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?

Even though the schema handles parameters well, the tool has 9 optional inputs, no annotations, no output schema, and no explanation of how the params relate to the task categories. An agent cannot fully infer what inputs are needed to obtain a gateway or what 'connection methods' will look like.

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 description coverage is 100%, so the baseline is 3; the property descriptions already explain each param. The tool description does not add meaningful relational meaning beyond that, such as which combinations of params are relevant for which tool categories.

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 the specific action: find a public pay-per-call tool gateway for task categories like weather, search, scrape, or voice, and return connection methods. It is clear enough to distinguish this tool from the sibling validator/hint tools, though the core term 'tool gateway' is somewhat jargon-heavy.

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 task categories 'weather, search, scrape, or voice' provide clear usage context, and the phrase 'Task text discarded' signals how it should be called. It omits explicit alternatives or when-not-to-use guidance, so it misses the top tier.

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