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 that ranking is 'transparent' and that it returns reasoning for each vendor, which adds behavioral context. However, it does not mention side effects, data sources, or any potential safety considerations, leaving room for more transparency.

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 sentences, front-loaded with the core purpose and followed by input semantics. Every sentence earns its place with no fluff or redundancy.

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 tool with three optional parameters and no output schema, the description covers purpose, output, and input meanings. It is complete enough for an agent to select and invoke the tool correctly, though it could detail scoring methodology or edge cases if those were important.

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 0% description coverage, but the description explicitly explains the meaning of all three parameters: 'functions needed', 'dev-integration flag', and 'budget-sensitive flag'. This adds semantic value beyond the raw schema and helps the agent map inputs to intent.

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 clearly states the tool ranks vendors for a practice, using a specific verb ('rank') and resource ('vendors'). It distinguishes itself from sibling tools like get_clearinghouse, list_clearinghouses, and vendors_by_function by emphasizing scored shortlist and reasoning output.

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?

The context is clear: use this tool when you need a ranked, scored shortlist of vendors with reasoning. It does not explicitly mention alternatives, but the purpose and output description sufficiently imply when this tool is appropriate, and nothing suggests exclusions.

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