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

With no annotations, the description must disclose behavioral traits. It mentions that task text is discarded and that it returns CLI setup, how-it-works, skill file, and remote MCP hops. However, it doesn't disclose side effects, network requirements, error behavior, or what happens with the 9 input parameters. The coverage is thin for a tool with no annotation safety profile.

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 sentences with no filler. The purpose is front-loaded and the behavioral note about task text is efficient. Every word earns its place.

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 tool with 9 parameters, no output schema, and no annotations, the description is insufficient. It doesn't explain how the parameters relate to the gateway search, what a 'skill file' is, or what constitutes a successful vs failed call. The agent would need to infer too much.

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 schema already documents each parameter. The description adds no additional parameter meaning or context. Baseline 3 is appropriate since the schema does the heavy lifting, though the description could have tied the parameters to the search logic.

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 clearly states a specific verb and resource: 'Find a public pay-per-call tool gateway (Monid)' and lists what it returns. However, it doesn't explicitly contrast with any sibling tools, though the name and description are specific enough to distinguish from the many shape/status 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?

No guidance on when to use this tool versus alternatives. The description doesn't mention any context, prerequisites, or exclusions. An agent would have no idea why to pick this over a sibling like 'web-fetch' or 'fetch-status'.

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