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

No annotations are provided, so the description must carry the full burden. It mentions a cost ($0.03/call) but does not disclose other behavioral traits such as read-only nature, side effects, rate limits, or required permissions. This is insufficient for a search tool.

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 long, immediately stating the core purpose and parameters, then providing a typical use case, source, and cost. It is front-loaded and free of filler.

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?

With 8 parameters, no output schema, and no annotations, the description is incomplete. It explains the general purpose but not parameter details, output structure, or usage constraints. Important aspects like pagination, rate limits, or error handling are absent.

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%. The description lists some parameters (billing code, state, payer, hospital CCN, rate type) but does not explain their usage, relationships (e.g., billing_code and billing_code_type), or constraints. Limit and offset are omitted. The description adds minimal value over the schema.

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 verb (search) and resource (hospital price-transparency negotiated rates) and lists parameters. It answers a specific question. However, it does not explicitly distinguish from the sibling tool hpt_code_stats, which may be similar but for statistics.

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 provides a use case query ('what do payers actually pay?') and indicates the data source. But it lacks explicit guidance on when to use this tool vs. alternatives, or when not to use it. No exclusions or prerequisites are mentioned.

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