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

With no annotations, the description carries the behavioral burden. It discloses that task text is discarded (privacy-relevant) and says it returns connection methods. It does not mention side effects, external calls, rate limits, or errors, so the behavior is only partially transparent.

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 exactly two sentences, front loads the purpose, and includes a privacy-relevant behavior without waste. Every phrase earns its place.

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 9-parameter, 0-required, no-output-schema tool, the description is reasonably complete: it states what it finds, what it returns, and that task text is discarded. It could clarify how the parameters map to the listed tasks, but the schema already covers each parameter, so the information is not strictly missing.

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?

The input schema has 100% coverage with descriptions for all 9 parameters, so the baseline is 3. The tool description adds minimal semantic value beyond the schema, mainly the notion of a task text being discarded, which is already reflected in several parameter descriptions. It does not significantly enrich the parameter meaning.

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 function: 'Find a public pay-per-call tool gateway for a task such as weather, search, scrape, or voice.' It names the resource type (pay-per-call tool gateway), the action (find), and the task categories. This clearly distinguishes it from siblings like weather-hint or web-fetch, which are direct data tools rather than a lookup/gateway finder.

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?

It gives clear task examples (weather, search, scrape, voice) that indicate when to use the tool. However, it does not explicitly mention when not to use it or point to specific alternatives among the many siblings, so it stops short of complete routing guidance.

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