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

With no annotations, the description carries the burden and does add useful behavior: it returns specific artifacts and says task text is discarded. It does not, however, disclose side effects, authentication, rate limits, or confirm it is side-effect-free, leaving part of the behavioral profile implicit.

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?

Three short sentences with no filler: purpose first, then return contents, then a data-handling note. Each sentence contributes distinct information, and the most important action verb is front-loaded.

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 description lists key return artifacts and warns that task text is discarded, which is helpful given there is no output schema. But with nine optional parameters and no annotations, it does not explain which parameters matter for a given invocation or what the returned payload looks like, so an agent has to rely on schema descriptions alone.

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 schema already explains every parameter. The description adds no parameter-specific meaning beyond reinforcing that task-like text is discarded, which is already reflected in the query parameter description.

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 opens with a specific verb and resource: 'Find a public pay-per-call tool gateway (Monid)' and lists the returned artifacts (CLI setup, how-it-works, skill file, remote MCP hops). It is clear about what the tool does, though it does not explicitly contrast itself with 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 use case is implied: call this when you need a Monid pay-per-call gateway index. However, there is no explicit when-to-use, when-not-to-use, or mention of alternatives among the 27 sibling tools, so an agent must infer the correct selection context.

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