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

With no annotations, the description carries the burden of explaining behavior. It only says 'Returns connection methods' and mentions discarded inputs, but leaves side effects, costs, error behavior, and actual processing steps unclear.

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 overall description is short and front-loaded, and the parameter descriptions are compact. However, the brevity contributes to ambiguity rather than providing a clear, well-structured usage model.

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?

There is no output schema, and the text does not explain the return format, expected inputs in combination, error cases, or how the listed parameters relate to the requested gateway. The tool is not self-contained enough for correct invocation.

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?

Though every parameter has a schema description, the descriptions are mostly negative or discard-oriented ('discarded after the shape check', 'no disk access', 'length check'), leaving unclear why these parameters exist or how they influence the returned connection methods.

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 action ('Find') and a resource ('public pay-per-call tool gateway'), with example task types, but the meaning of 'gateway', 'connection methods', and 'tool index' is vague and not clearly distinguished from sibling tools.

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?

No explicit guidance on when to use this tool versus alternatives like weather-hint, search-query-len, or normalize-url. The description implies task categories but does not state conditions for selection.

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