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

No annotations are provided, so the description carries the full burden. It discloses that 'Task text discarded' for some inputs, which is a useful behavioral note, but it does not clarify whether the tool makes external calls, has side effects, or what happens to the gateway result. This is minimal transparency for a tool that likely accesses external resources.

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 a single sentence that front-loads the core purpose and lists the outputs. It is efficient and avoids redundancy, though it could be slightly clearer about the intended usage context.

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 9 optional parameters, no output schema, and no annotations, the description should explain how to invoke the tool and what to expect. It only says it finds a gateway and returns four items, but does not clarify which parameters are relevant, how to pass them, or the format of the response. An agent would struggle to know what inputs to provide.

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 schema already documents all 9 parameters. The description does not add any parameter-specific meaning beyond what the schema provides, so it stays at the baseline of 3. It does not mention how parameters like 'url' or 'query' are used in the gateway lookup.

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 specific verb 'Find' and a resource 'public pay-per-call tool gateway (Monid)', and lists what it returns. This clearly distinguishes it from sibling tools, which are all URL/shape/status checks. However, 'Monid' is not explained, leaving some ambiguity about the exact nature of the gateway.

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 implies when to use it (when you need a pay-per-call gateway) but does not explicitly contrast it with alternatives or state when not to use it. The phrase 'Find a public pay-per-call tool gateway' gives some context, but no exclusions or alternative tool names are provided.

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