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

No annotations are present, so the description carries the behavioral transparency burden. It does disclose one meaningful trait: 'Task text discarded', indicating the tool ignores task text and implying a read-only lookup. It does not mention side effects, authentication needs, rate limits, or cost implications of the pay-per-call gateway.

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 a single front-loaded sentence that states the purpose, lists the returned artifacts, and adds a behavioral caveat. Every clause contributes value, with no filler or redundant restatement.

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 no output schema and no annotations, the description does enough to state what the tool returns and that task text is ignored, but it leaves ambiguity about how to invoke it correctly: no required parameters are indicated, and the relationship between the six input properties and the returned gateway information is unexplained.

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 the baseline is 3. The tool description adds no extra meaning about how the six parameters relate to finding the gateway; it only mentions task text, which is not represented as a parameter in the schema. The schema itself carries the parameter documentation burden.

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)' and lists what it returns (CLI setup, how-it-works, skill file, remote MCP hops). It is clear enough to distinguish this tool from the sibling list, though 'Monid' is unexplained and no explicit sibling differentiation is given.

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?

Usage is implied: call this tool when you need to find the Monid pay-per-call gateway and its associated setup or hop information. However, the description gives no explicit when-not-to-use guidance, no alternatives, and no conditions for selecting it over other tools.

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