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

With no annotations provided, the description carries the behavioral burden. It does disclose a meaningful behavioral trait: 'Task text discarded.' It also implies a read-only lookup by saying 'Find' and lists what it 'Returns.' However, it does not explicitly state whether any external calls are made, whether state changes occur, or whether authentication/costs are involved, despite the 'pay-per-call' framing.

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 tight and front-loaded: purpose, returned artifacts, and behavioral note are each in their own short sentence. There is no filler. It loses one point because 'pay-per-call tool gateway' and 'Monid' introduce jargon without clarification, which slightly hurts readability.

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?

This tool has 9 parameters, all optional, no output schema, and no annotations. The description does not say whether the parameters are filters, examples, or entirely ignored, nor does it specify how an agent should invoke the tool (e.g., with no arguments, with one relevant field, or with all fields). The return list is useful, but the missing invocation guidance makes the definition incomplete for reliable use.

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%, so each parameter is already documented in the input schema, including discard behavior. The description adds no parameter-specific meaning, which is acceptable at the baseline 3, but it also fails to explain how the nine unrelated-looking parameters relate to finding a Monid gateway.

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 verb and resource: 'Find a public pay-per-call tool gateway (Monid).' It also lists the concrete return artifacts (CLI setup, how-it-works, skill file, remote MCP hops), which helps an agent understand the tool's function. However, 'Monid' is not explained and there is no explicit differentiation from the large sibling set, so it falls short of a 5.

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 use case is implied: call this when the user needs Monid gateway setup or remote MCP hop information. But the description gives no explicit when-to-use or when-not-to-use guidance and does not mention any alternative tools, even though there are 27 siblings with overlapping discovery/hint purposes.

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