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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint, and sideEffectsHint, so the safety profile is covered. The description adds the useful behavioral detail that task text is discarded and lists output artifacts, but it does not address failures, auth, or parameter handling beyond that.

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 a single front-loaded sentence with no redundant filler. It communicates purpose, outputs, and a behavioral caveat efficiently, though the unexplained 'Monid' term slightly reduces clarity.

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 low-complexity tool with no output schema, the description lists the main returned artifacts and notes discarded task text. However, it does not explain what 'Monid' is, how the parameters relate to the gateway search, or when this tool should be preferred over similar siblings.

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 has 100% description coverage, with each parameter carrying a note such as 'discarded after the shape check.' The tool description does not add parameter-level meaning beyond the schema, so the baseline 3 is appropriate.

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 names a specific action ('Find') and a specific resource ('public pay-per-call tool gateway (Monid)'), and lists what it returns. It is clear enough, though 'Monid' and 'tool gateway' are unexplained jargon and it does not explicitly distinguish itself from the many 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?

There is no explicit guidance about when to use this tool versus alternatives. The phrasing implies it is for finding a Monid gateway, but no sibling alternatives are named and no when-not-to-use context is provided.

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