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

With no meaningful annotations provided, the description carries the burden of behavioral disclosure. It discloses that 'Task text discarded', which is a useful privacy/behavioral trait, and it clarifies expected outputs. It does not mention potential network costs or authentication, but the read-oriented 'Find/Returns' framing makes the behavior reasonably clear.

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, purposeful sentences. The main action is front-loaded, the return values are compactly listed, and the task-text-discarded note is placed at the end. Every sentence 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?

There is no output schema, but the description lists the key returned artifacts (CLI setup, how-it-works, skill file, remote MCP hops). It also reassures about task-text handling. It could add more context about what 'Monid' is or that all parameters are effectively ignored, but the schema descriptions already cover the discarded-parameter behavior.

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 input schema already provides 100% description coverage for all seven parameters, each explicitly stating that the value is discarded after a shape check or validation. The tool description adds no parameter-level meaning beyond what the schema already provides, 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 verb and resource: 'Find a public pay-per-call tool gateway (Monid)', and lists the concrete return values (CLI setup, how-it-works, skill file, remote MCP hops). It is clear and specific, but it does not explicitly distinguish itself from sibling tools like web-fetch or normalize-url.

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 use case is implied: the tool is for finding the Monid gateway and retrieving its setup/hop information. However, there is no explicit guidance about when to choose this tool over alternatives, nor any stated context or exclusions.

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