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

With no annotations, the description carries the full burden of behavioral disclosure. It does add useful context by stating that task text is discarded and that the return values are setup/docs and remote MCP hops. However, it does not disclose whether the call is read-only, whether it makes network requests, or whether any costs are involved.

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, with the key action and resource in the first sentence. The final clause, 'Task text discarded,' is concise but somewhat confusing because no parameter clearly represents task text.

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, no output schema, and no annotations, but the description never connects those parameters to the gateway lookup or explains what inputs are needed. An agent would not know what to pass to obtain the stated returns, making the definition incomplete for practical invocation.

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?

The schema already provides descriptions for all 9 parameters, so the baseline is 3. The description itself adds no additional meaning about the parameters and does not explain how any of them relate to finding the Monid gateway or producing the stated outputs.

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 concrete return values such as CLI setup, how-it-works, skill file, and remote MCP hops. It is not a tautology, but it does not name or contrast any sibling tool, and 'Monid' is 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 implies when to use the tool: when an agent needs the Monid gateway's setup or integration materials. However, it gives no explicit when-not-to-use guidance and names no alternatives, so the routing decision is left mostly implicit.

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