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

With no annotations present, the description carries the behavioral disclosure burden. It does add real behavior: 'Task text discarded' and the list of returned artifacts. It does not mention authentication, rate limits, costs, or whether external requests are made, so the behavioral picture is partial but not empty.

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?

Three short sentences with no redundant phrasing. Purpose is front-loaded, outputs are listed compactly, and the privacy-relevant discard behavior is a separate useful sentence. Every part 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?

The description explains what the tool returns and that task text is discarded, but with six unrelated-looking parameters and no output schema or annotations, it does not clarify which parameter (if any) drives the lookup or how the parameters relate to finding the gateway. The rich per-parameter schema descriptions prevent this from being a critical gap, so it is minimally adequate rather than fully complete.

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 even though the description itself says nothing about parameters, the structured schema already documents each one including discard behavior. The description adds no value beyond that baseline.

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 states a specific verb ('Find') and resource ('a public pay-per-call tool gateway (Monid)'), then lists concrete outputs: CLI setup, how-it-works, skill file, and remote MCP hops. This makes it distinguishable from the sibling utility tools, though it does not explicitly name an alternative.

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 intended use is implied by 'Find a public pay-per-call tool gateway' and by the promised setup/skill output, but the description gives no explicit when/when-not guidance and does not mention alternatives such as web-etch, fetch-status, or normalize-url. Usage is inferable rather than clearly specified.

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