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

No annotations are provided, so the description must carry the full behavioral burden. It states only that it 'Returns only figures the site already states,' which is a single reliability note; it does not disclose whether output is static, whether it requires auth, pagination, or formatting. For a zero-parameter reference tool, more context is needed.

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 long sentence that front-loads a string of topics before revealing the tool's function. It is reasonably compact but reads as a list dump rather than a front-loaded purpose statement.

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 zero-parameter, no-output-schema reference tool, the description covers the subject matter but omits the return shape and usage context. With no annotations and no output schema, the description should do more to explain what an agent receives and when to prefer this over sibling price tools.

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 tool takes no parameters, so there are no parameter semantics to document and the baseline is 4. The description adds no parameter information, which is appropriate given the absence of inputs.

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 enumerates the topics covered (buyer ask price, free files, state seat, seller introduction, fleet quoting, grades A/B/C), which conveys the resource, but it never states a verb like 'returns' or 'explains' until the final clause. It reads as a topic list rather than a clear statement of what the tool does, though the closing sentence 'Returns only figures the site already states' does supply the action. Siblings like get_price_band and list_price_bands are not distinguished from.

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 guidance on when to call this tool versus get_price_band, list_price_bands, or the other siblings. The agent must infer that this is a reference/glossary lookup, with no stated conditions or exclusions.

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