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

With no annotations, the description carries the behavioral burden. It discloses that task text is discarded and that the tool returns CLI setup, how-it-works, skill file, and remote MCP hops. However, it does not clarify whether any network calls occur, whether the 9 optional parameters are inspected or simply echoed, or whether any side effects or access requirements exist.

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 short and front-loaded: it states the core purpose, summarizes the return contents, and includes an important discard caveat. No sentence is wasted, and the structure makes the tool's basic behavior immediately clear.

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 tool has 9 optional parameters and no output schema, yet the description gives no indication of which parameter(s) to supply or what a successful call looks like. The return-list helps but is not enough to guide invocation, especially given the large optional parameter surface and no usage or routing rules.

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 global statement 'Task text discarded' adds a small behavioral note beyond the schema, but the description does not explain how or why the 9 parameters relate to the tool's main purpose, nor how to choose among them.

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 and resource: 'Find a public pay-per-call tool gateway (Monid)' and lists the returned artifacts. It distinguishes itself from the sibling validators by focusing on a gateway discovery/indexing function rather than checks or fetches, though it does not explicitly differentiate itself by name.

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 is given on when to use this tool versus any of the 27 siblings. The description does not state what kinds of calls or tasks warrant using it, what inputs are expected, or which alternatives to prefer. 'Task text discarded' is a caveat, not usage guidance.

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