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

There are no annotations, so the description carries the behavioral disclosure burden. It explicitly states 'Task text discarded' and the schema descriptions reinforce that several inputs are discarded after the shape check/call. This provides meaningful transparency about input handling, though it does not cover auth, rate limits, or side effects beyond the discard behavior.

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 two sentences with no wasted words. The first sentence names the action and target, and the second lists outputs plus the key behavioral caveat. It is efficiently front-loaded and easy to parse.

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?

For a discovery/lookup tool, the description is largely complete: it names the target, enumerates return outputs, and discloses the input-discard behavior. There is no output schema or annotations, so the return-value enumeration is valuable. It could add more about when to invoke it, but the core calling context is present.

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 documents all six parameters with descriptions, so schema coverage is 100%. The tool description adds little about parameters themselves; 'Task text discarded' is not tied to a specific schema property. Baseline 3 is appropriate because the schema does the heavy lifting.

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 ('Find a public pay-per-call tool gateway') and identifies the resource (Monid), then lists the four return artifacts (CLI setup, how-it-works, skill file, remote MCP hops). It is clear about what the tool does, though it does not explicitly contrast it with sibling tools.

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 that this tool is for locating a Monid pay-per-call gateway and retrieving associated setup/hop information. However, it gives no explicit guidance about when to use this tool instead of a sibling, nor any conditions, prerequisites, or exclusions.

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