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

With no annotations, the description carries the transparency burden. It does add useful disclosures: 'Task text discarded' and the list of returned items. However, it does not mention potential costs, remote calls, authentication, failure behavior, or what happens to the input parameters, leaving meaningful behavioral 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 two short sentences with no filler. It front-loads the primary purpose, lists expected outputs, and includes an important privacy-related caveat. Every sentence 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?

The tool has 9 optional parameters, no output schema, no annotations, and many siblings, yet the description does not explain how the parameters relate to finding the gateway, what the output format is, or what 'CLI setup,' 'skill file,' and 'remote MCP hops' concretely mean. An agent would struggle to know what input to provide and what to expect back.

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?

Although schema description coverage is 100%, nearly every parameter description says the value is discarded or only used for a shape/length check. This makes the parameters semantically clear as no-ops but fails to explain how an agent should populate them to achieve the tool's stated purpose. The disconnect between the 9-parameter schema and the 'task text discarded' behavior is not resolved.

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 (Monid)' and lists the returned artifacts. It is clear enough to distinguish this from generic fetch or validation tools, though it does not explicitly contrast it with sibling tools like web-fetch or normalize-url.

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 guidance on when to use this tool versus alternatives, no exclusions, and no mention of which sibling tools might be more appropriate. The description implies use when looking for Monid, but leaves all routing decisions to inference.

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