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

No annotations are provided, so the description carries the burden: it discloses deterministic scoring, inputs (verified pricing, agent-friction, health), the all-use-case behavior, and returned weighted and per-dimension scores. It omits auth, rate limits, and pagination, which are less central for a ranking read but still absent.

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?

Three tight sentences, front-loaded with purpose and optional behavior, and no redundant wording. The parenthetical scoring basis is efficient and useful.

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 two-parameter ranking tool with no output schema or annotations, it describes scoring basis, optional use_case behavior, and return shape. It still lacks guidance on valid category/use_case values or sibling routing, but core invocation is covered.

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 coverage is 0%, and the description adds meaning for use_case by stating that omitting it returns every use case and that scoring is per use case. It does not explain valid category/use_case values or formats, so it only partially compensates for the schema gap.

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?

States a specific verb and resource: get ranked vendors for a category, with per-use-case scoring. It is distinguishable from compare_vendors and get_vendor by being a category-level ranking, though it does not explicitly name alternatives.

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?

Explains the use_case omission behavior, which guides parameter use, but gives no explicit when-to-use guidance versus compare_vendors, recommend, or search_vendors, and no exclusions.

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