Tool DescriptionsB

Average 3.4/5 across 2 of 2 tools scored.

Server CoherenceA
Disambiguation5/5

The two tools have distinct purposes: one lists hospitals with metadata, the other retrieves cost data for a specific hospital. There is no overlap.

Naming Consistency5/5

Both tools follow a consistent verb_noun snake_case pattern: list_hospitals and get_hospital_chargemaster_cost.

Tool Count3/5

Two tools is minimal for a medical pricing API; while it covers listing and retrieval, the scope feels limited. It is borderline but not extreme.

Completeness2/5

The API lacks ability to search by procedure, compare costs, or filter hospitals. Only basic listing and single cost lookup are provided, which are significant gaps for typical use cases.

hospital_idYesOpaque hospital identifier from list_hospitals.
methodologyNoPricing methodology. Omit to aggregate across all methodologies.

foundNoWhether a matching chargemaster cost record was found.
hospitalNoHospital name returned by the MedPrice AI backend.
descriptionNo
Behavior2/5

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

Annotations already indicate readOnlyHint=true, destructiveHint=false, so the safe-read behavior is covered. However, the description adds no additional behavioral context such as authentication needs, data freshness, or error handling. The minimal description does not enhance transparency beyond structured metadata.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short (one sentence), which is concise but at the expense of valuable information. It is not overly verbose, but the brevity results in under-specification.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that the tool has 4 parameters (3 required) and an output schema (not shown), the description is too sparse. It does not clarify what 'chargemaster cost' means, how pricing methodology affects results, or any edge cases. The presence of an output schema slightly reduces the need for return value explanation, but overall the description lacks contextual richness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 75% (3 of 4 parameters have descriptions), but the tool description itself provides no parameter details. The undocumented 'code' parameter remains unexplained, and the description does not compensate for this gap. The description adds no value beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a clear verb-resource pair ('Lookup hospital chargemaster cost') that immediately conveys the tool's purpose. It distinguishes itself from the sibling tool 'list_hospitals' by focusing on cost lookup rather than listing.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use or when to avoid this tool. There is no mention of prerequisites, context, or alternatives beyond the sibling list, which limits its utility for an AI agent deciding between tools.

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

list_hospitalsList supported hospitalsA
Read-only
Inspect

Returns the hospitals supported by the medprice.ai API, with their hospital_id (opaque DB key), EIN, name, locations, and last_updated_on. Supports pagination.

ParametersJSON Schema
NameRequiredDescriptionDefault
page_sizeNoMaximum number of hospitals to return. Defaults to 20, capped at 100.
page_tokenNoOpaque token from a previous list_hospitals response. Omit for the first page.

Output Schema

ParametersJSON Schema
NameRequiredDescription
hospitalsNo
next_page_tokenNoOpaque pagination token, empty when there are no more results.
Behavior3/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the description adds some value by specifying the returned fields and pagination support. However, it does not discuss potential performance characteristics or rate limits beyond pagination.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences, front-loaded with the main purpose, no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the presence of an output schema and the tool's simplicity, the description adequately covers purpose, result fields, and pagination. It could optionally mention that an empty result is possible, but this is not a major gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with both parameters described. The description adds no new meaning beyond what the schema provides; it only confirms pagination support, which is already implied by the parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states that the tool returns the hospitals supported by the medprice.ai API, with specific fields listed (hospital_id, EIN, name, locations, last_updated_on). This distinguishes it from the sibling tool get_hospital_chargemaster_cost, which presumably retrieves cost data for a specific hospital.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description does not explicitly state when to use this tool versus alternatives, but it mentions pagination and the sibling tool is named, implying this is for initial listing. However, no exclusion criteria or prerequisites are provided.

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