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

With no annotations, the description carries the full burden and it does add behavioral facts: it returns specific artifact types and says 'Task text discarded.' However, it does not disclose whether remote MCP hops are merely returned or actually invoked, whether invocation has cost implications, or what side effects, if any, 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?

Three short sentences, front-loaded with purpose, followed by return contents and a behavioral caveat. Every sentence earns its place and there is no filler.

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?

There is no output schema and no guidance connecting the gateway-index purpose to the nine unrelated-looking optional parameters. The description does not say whether any parameter is needed, how the returned 'CLI setup'/'skill file'/'remote MCP hops' are structured, or what invoking the tool entails, leaving an agent to guess at 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?

Schema description coverage is 100%, so the input schema already documents all nine optional parameters, including discard/validation notes. The description itself adds almost nothing about parameters beyond the cryptic 'Task text discarded,' so the baseline of 3 applies.

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 action and resource — 'Find a public pay-per-call tool gateway (Monid)' — and lists what it returns: CLI setup, how-it-works, skill file, and remote MCP hops. It is clearly distinct from the sibling validation/utility tools, though 'Monid' is not explained and no sibling is named.

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 opening sentence defines when to call the tool: when the agent needs to find the Monid public pay-per-call gateway. That is a clear use context, but the description does not name alternatives or state when not to use it, so it stops short of full routing guidance.

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