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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It notes 'Task text discarded' and that it 'Returns connection methods,' but it omits critical details such as whether the tool is read-only, incurs costs (despite 'pay-per-call' referring to the gateways, not this tool), performs network calls, or has any side effects. The disclosure is too sparse for a tool with no annotation safety profile.

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, concise sentence that front-loads the purpose and then adds a note about data handling. It avoids fluff and is efficient, though it could be more structured by separating the return value statement from the discard note. Still, it is well above average in conciseness.

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 parameters, no output schema, and no annotations, the description is too brief to be complete. It does not explain which parameters are relevant for which task types, what the 'connection methods' look like, or how the tool should be invoked for different use cases. An agent would likely need to inspect all parameter schemas and infer usage, leaving significant gaps.

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 individually. The description adds only a generic note about task text being discarded, which does not map to any specific parameter or add operational semantics beyond the schema. Baseline 3 is appropriate.

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'), a specific resource ('public pay-per-call tool gateway'), and names example tasks (weather, search, scrape, voice). It clearly distinguishes this tool from its siblings, which are all direct task-specific tools, by positioning it as a meta-router for discovering gateways.

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 usage by giving example tasks ('for a task such as weather, search, scrape, or voice'), but it does not explicitly state when to use this tool over a direct sibling, nor does it mention exclusions or alternatives. The guidance is implicit rather than explicit.

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