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

The description discloses a meaningful behavioral trait: 'Task text discarded' indicates the input task is not retained. It also states what the tool returns. However, with no annotations and no output schema, it does not clarify whether network calls are made, whether anything is executed, or what side effects might occur.

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. The main purpose is front-loaded, and each sentence adds distinct information: what it finds, what it returns, and a key behavioral caveat.

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 nine unrelated optional parameters, no annotations, and no output schema, yet the description does not explain how the parameters relate to the stated purpose or whether calling with no arguments is sufficient. It describes return items at a high level but leaves enough ambiguity that an agent may not know how to invoke it correctly.

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 coverage is 100%, so the description does not need to repeat parameter meanings. The schema already documents each parameter, including discard/no-disk-access notes. The description adds no parameter-level guidance on how to choose among the nine optional parameters.

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 names a specific action and resource: 'Find a public pay-per-call tool gateway (Monid)' and lists concrete outputs. It is distinguishable from the sibling tools, though it leaves 'Monid' unexplained and does not clarify whether this is a search or a lookup.

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 provides a clear use context: use this tool to locate the Monid gateway and obtain CLI setup, how-it-works info, skill file, and remote MCP hops. It does not explicitly mention when not to use it or name alternatives, but the purpose is specific enough to guide selection.

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