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

Annotations already indicate read-only, idempotent, and open-world behavior. The description adds that the sample is 'bounded API-order' and includes an 'authoritative matching-row count', providing useful behavioral context beyond the annotations. No contradictions.

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?

Two sentences with essential information placed upfront. No unnecessary words or redundancy. The description is efficient and easy to parse.

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?

The description covers the core functionality, constraints, and what the tool is not. Given the output schema exists (though not shown), the description need not detail return format. For a read-only sample tool, it is largely complete, though parameter details could be enriched.

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. It mentions hcpcs_code, year, and state, but omits limit and offset. The term 'bounded' implies pagination, but no explicit parameter guidance is given. This is insufficient for a tool with 5 parameters.

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 returns a bounded sample of DME supplier rows for an exact HCPCS code and year, optionally filtered by state, with an authoritative row count. It explicitly distinguishes itself from similar tools by stating it is not a supplier ranking or total market size.

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 description explains what the tool does and what it does not do (not a ranking or total market size), which helps differentiate it from siblings. However, it does not explicitly state when to use this tool over alternatives or provide conditions for use, leaving some ambiguity.

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