D1/5.0
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, but the description adds no behavioral information. It does not mention that it is read-only, nor does it disclose any operational characteristics such as response format or rate limits. The pricing note is not behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness1/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely short but not concisely informative; it is a pricing string with no functional content. It is under-specified rather than concise, providing no structure or front-loaded useful information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool that likely returns a bundle of comparable property data, the description is completely inadequate. There is no explanation of output, required parameter, or intended use case. Given the complexity implied by the name and sibling tools, the description leaves an agent without any guidance.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has one parameter (gnaf_id) with no description, and schema coverage is 0%. The description does not explain what gnaf_id represents or how it should be provided. It adds zero meaning beyond the raw type.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose1/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description is only a pricing note ('Price: 74¢ per call.') and does not state what the tool does. The name hints at 'All comparables — bundle', but the description provides no verb, resource, or scope. It fails to distinguish from siblings like properties_comparables_cma_comp_set.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. There is no mention of when to call it, what inputs are expected, or any exclusions. The pricing note gives no usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
