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

The description discloses that task text and parameter values are discarded after checks, offering partial transparency. However, it does not explain the actual behavior such as whether external calls are made, what 'connection methods' entails, or any side effects.

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 concise, consisting of a single sentence that is well-structured and to the point. It avoids unnecessary verbosity, though the brevity sacrifices clarity.

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?

The tool has 9 optional parameters and no output schema or annotations. The description gives only a vague outline of its function and output, lacking essential details about how parameters are used together, what 'connection methods' are, and the expected response format, making it incomplete 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?

All 9 parameters have descriptions in the schema, achieving 100% coverage. The descriptions are terse but provide hints (e.g., 'discarded after the length check'), which adds some meaning beyond the parameter names. Yet the overall purpose of the tool muddies the interpretation of these parameters.

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 it finds a public pay-per-call tool gateway for tasks like weather, search, scrape, or voice, and returns connection methods. However, it is vague about what 'gateway' means and how the parameters relate to the task, making it difficult to distinguish from other 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 guidance is provided on when to use this tool versus its siblings. It does not mention any conditions or criteria for selecting this tool, leaving the agent without context for appropriate usage.

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