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

With no annotations, the description carries the full burden. It does disclose that the tool 'Returns' specific artifacts and that 'Task text discarded,' which is useful transparency. However, it does not explain whether network access occurs, whether pay-per-call charges apply beyond the name, what happens with the nine optional parameters, or what failure modes exist.

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 short, front-loaded with the main action, and each sentence adds distinct information: what it finds, what it returns, and that task text is discarded. It is appropriately sized even if somewhat cryptic.

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?

Given no output schema, no annotations, nine optional parameters, and an unusual tool name, the description is not complete enough. It fails to explain why those nine parameters exist, how they relate to finding the gateway, what a 'remote MCP hop' is, or how an agent should choose and populate the parameters.

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 coverage is 100%, so the baseline is 3 and the description is not required to repeat parameter details. It does not add meaningful parameter-level guidance, and the phrase 'Task text discarded' seems disconnected from the actual parameters. Still, each parameter is individually documented in the schema.

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 names a specific resource ('public pay-per-call tool gateway (Monid)') and a verb ('Find'), but the purpose remains vague because 'Monid' and 'pay-per-call tool gateway' are unexplained jargon. It does not clearly distinguish this tool from the many sibling utility tools, and 'agent-tool-index' as a name does not align with the stated gateway-finding behavior.

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 when-to-use guidance is provided, and no alternatives or exclusions are mentioned. The description implies you should call it when you need Monid gateway information, but it does not say how this relates to the sibling tools or what kind of task should route here.

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