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 disclose one important behavioral trait: it does not spend money. This implies a read-only, non-costly operation, which is valuable context. Still, it omits details like side effects, authorization requirements, match semantics, and what happens when no capability is found, though the output schema may cover return shape.

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 tight sentences with no filler. The core purpose is front-loaded, and the important 'Does not spend money' behavior is isolated clearly. 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?

For a simple read-only resolution tool, the description covers the main behavioral caveat (no cost) and relies on the output schema for return details. However, it does not explain parameter usage or when to choose this over adjacent quote/estimate siblings, leaving an agent with only partial context for correct 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 0%, so the description must compensate, but it says nothing about the 'intent' or 'requirements' parameters. The parameter names are somewhat self-explanatory, but the description does not clarify how requirements constrain the capability match or what form intent should take. This falls short because the schema itself provides no descriptions.

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 uses a specific verb and resource: 'Determine whether Hydracept already provides a suitable capability.' This clearly states the tool checks for existing capability fit rather than creating or estimating something. It distinguishes from quote/estimate siblings via 'already provides' and 'Does not spend money,' though it does not name a sibling explicitly.

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?

'Does not spend money' gives a useful decision signal, implying it should be preferred before cost-incurring alternatives like quotes or estimates. However, there is no explicit when-to-use guidance, no named alternatives, and no exclusions or conditions for when another tool would be more appropriate.

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