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

There are no annotations, so the description carries the burden. It does disclose meaningful behavior: the tool returns CLI setup, how-it-works, skill file, and remote MCP hops, and it discards task text. However, it does not clarify network access, cost implications, authentication, or whether any state is persisted.

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 three short sentences with no filler and front-loads the core purpose before listing outputs and a behavioral caveat. It earns a 4 rather than 5 because terms like 'Monid' and 'task text' are not clarified, though the structure itself is efficient.

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 nine optional parameters and no output schema, the description gives an agent little guidance on how to construct a valid call, which parameters matter, or what the returned index structure looks like. The listed return artifacts are helpful, but operational completeness is low for a tool with this much schema surface area.

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 description adds no parameter-specific meaning beyond the schema; it only restates that task text is discarded, which the schema already conveys for several parameters. It also does not explain why all nine parameters are optional or which one selects the 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 uses an explicit verb ('Find') and names a concrete resource ('public pay-per-call tool gateway (Monid)'), then lists what it returns. This distinguishes it from the sibling URL/format/status helpers. It is not a 5 because 'Monid' and the relationship between the index and the gateway are left unexplained.

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 description gives no explicit guidance about when to use this tool versus the 27 siblings, no exclusions, and no alternative tool names. The only usage signal is the verb 'Find', which leaves routing to the agent largely to inference.

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