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

Annotations already declare the operation read-only, idempotent, and non-destructive, and the description adds meaningful context beyond that: it explicitly discloses that task text is discarded and that several parameters are discarded after shape checks. This is useful privacy-related transparency, though auth or rate-limit behavior is not mentioned.

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?

Two sentences are used efficiently: the first states the core purpose, and the second lists return artifacts and a key privacy behavior. There is no filler or repetition, and the most important information is front-loaded.

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 description lists the return artifacts but does not explain how the six heterogeneous parameters relate to finding the Monid gateway, which parameters are required, or what the result looks like in practice. Given no output schema and a non-obvious input schema, an agent could still be unsure what to pass.

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 schema provides 100% description coverage for all six parameters, so the description does not need to repeat their meaning. The main description adds no additional parameter guidance beyond the general 'task text discarded' note, which is already reflected in several parameter descriptions.

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 first sentence states a specific verb and resource: find a public pay-per-call tool gateway (Monid), and the second lists the concrete return artifacts (CLI setup, how-it-works, skill file, remote MCP hops). It is clearer than a tautology but does not explicitly differentiate itself from siblings like web-fetch or citation.

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 phrase 'Find a public pay-per-call tool gateway' implies the usage context, and the description of returned artifacts hints at when an agent would want this tool. However, there is no explicit when-to-use/when-not-to-use guidance or mention of alternatives among the many sibling tools.

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