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

No annotations are provided, so the description carries the full burden. It discloses that task text is discarded and that each parameter is discarded after a shape or length check, which is transparent about input handling. However, it doesn't describe the return format, potential side effects, or why the parameters exist at all, leaving gaps.

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 three short sentences, front-loading the purpose, listing the returns, and adding a behavioral note. Every sentence contributes, with no filler or redundancy.

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 thin. It lists returned items but doesn't explain the parameters' role, the return format, or the tool's overall workflow. For a tool with this complexity, it is incomplete and leaves the agent guessing about how to use it effectively.

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%, and each parameter already includes its own 'discarded after' note. The tool description adds no additional semantic meaning beyond what the schema provides, so the baseline of 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 clear and specific purpose: finding the Monid pay-per-call gateway and listing the returned artifacts. It is distinct from sibling tools, which are generic utilities, though it doesn't explicitly name alternatives. The verb 'find' and the resource 'Monid' are clear.

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?

There is no explicit guidance on when to use this tool versus alternatives. The purpose is implied as a niche lookup, but no conditions or exclusions are given. It doesn't mention when not to use it, leaving the agent to infer.

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