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

No annotations are present, so the description carries the burden. It does disclose that task text is discarded and lists the returned artifacts, which provides some transparency. However, it does not mention potential side effects, authentication needs, network behavior, or cost implications despite the 'pay-per-call' context.

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 efficiently written sentences with the main purpose front-loaded. Each clause carries distinct information—resource, returned artifacts, and a behavioral note—with no redundancy or filler.

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?

For a simple lookup tool with six schema-covered parameters and no output schema, the description adequately conveys the output categories and the fact that task text is ignored. It could be slightly more complete with output format or authorization hints, but it is largely sufficient for correct invocation.

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 input schema provides descriptions for all six parameters (100% coverage), so the description adds no parameter-specific detail beyond what is already structured. The 'task text discarded' note is a general behavioral observation, not a parameter explanation. Baseline 3 applies.

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 uses a specific verb 'Find' with a clearly identified resource ('public pay-per-call tool gateway (Monid)') and enumerates what it returns (CLI setup, how-it-works, skill file, remote MCP hops). It is unambiguous about the tool's function but does not explicitly distinguish it from sibling tools.

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 when to use it, but there is no explicit statement of when to choose this over alternatives, nor any exclusions or prerequisites. This is implied usage rather than direct guidance.

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