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

With no annotations provided, the description carries full burden. It explains the data source (CMS NPPES full monthly file joined to directory), mentions 'precise new-provider dating', and lists filters and sort options. No destructive behavior is indicated.

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 value proposition. It includes the price and filter options concisely. Every sentence adds value with no waste.

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?

Given no output schema and no annotations, the description covers the essential purpose, filters, sort, and pricing. It does not describe output format or pagination behavior, but the parameters (limit, offset) imply pagination. Overall, it is sufficiently complete for an agent to understand the tool's capability.

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 80%, so baseline is 3. The description adds context about the overall query purpose (new providers since a date by taxonomy and state) but does not significantly elaborate on individual parameter meaning beyond what's in the schema. It provides useful context without repeating schema details.

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 searches for newly-enumerated NPIs with exact enumeration date and taxonomy detail, using specific verbs and resources. It differentiates from sibling tools focused on other healthcare provider data (e.g., hospitals, dialysis) by specifying NPPES enumeration.

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 answers the question 'which providers/organizations of a given taxonomy were newly issued an NPI in my state since a date?' and lists filters. It provides context for when to use this tool, though it doesn't explicitly state when not to use it or name alternatives.

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