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

With no annotations, the description must disclose behavioral traits, but it only says 'Returns connection methods' and 'Task text discarded.' It does not state whether the tool is read-only, makes external calls, incurs costs (despite 'pay-per-call'), requires authentication, or has any side effects. This is a significant gap for a tool that likely orchestrates external API access.

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 core purpose. It avoids redundancy and is efficient, though it sacrifices necessary detail for brevity.

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?

For a tool with 9 optional parameters, no output schema, and no annotations, the description is grossly incomplete. It does not explain what 'connection methods' looks like, how to interpret the response, what the parameters do in the gateway selection, or any constraints. An agent would struggle to use this correctly.

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 description adds no parameter-level meaning beyond the schema; it does not explain how each parameter relates to finding a gateway or which parameter indicates the task type. The schema itself is unhelpful (most fields are 'discarded after check'), so the description fails to compensate.

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 and resource ('Find a public pay-per-call tool gateway') and lists example tasks (weather, search, scrape, voice). However, it does not clarify how the task is specified—none of the 9 parameters are named 'task' and several are explicitly discarded. This ambiguity weakens the clarity, making it distinguishable from siblings only by the gateway concept, not by input handling.

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 gives a general context (tasks like weather, search, scrape, voice) but provides no guidance on when to use this tool versus the many siblings (e.g., weather-hint, search-query-len). There is no mention of alternatives or exclusion criteria, so an agent cannot decide between this and other tools.

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