Read-onlyIdempotent

Use this when an employer asks where RxRooster shows anonymous public CRNA service options or approximate U.S. coverage. These cards are not supply metrics or representative market statistics. Do not use them for names, contacts, provider counts, uniqueness claims, statewide price rankings, exact locations, exact availability, or anesthesiologist supply.

TDQS

A3.9/5.0

Behavior4/5

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

Annotations already cover readOnly, idempotent, non-destructive, and closed-world, so the description's real contribution is the negative framing: these are not supply metrics, not representative market statistics, and not a source for counts, uniqueness claims, or exact locations. That boundary-setting meaningfully prevents misuse. It stops short of 5 because it says little about result shape or paging behavior beyond what structured fields already convey.

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

Conciseness4/5

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

The trigger condition is front-loaded and the whole definition is two sentences. The long exclusion list is dense but each item corresponds to a distinct failure mode the agent could otherwise stumble into, so little is wasted. Slightly list-heavy but appropriately sized.

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?

An output schema exists, so return values need not be explained, and annotations handle safety. The description supplies the missing piece — when this tool is appropriate and what its output must not be interpreted as. Only minor gaps remain, such as how area_query interacts with state or what paging the caller should request.

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 description coverage is 100% and every parameter is documented inline, including the CRNA-only constraint on provider_type, so the schema carries the burden. The description adds no syntax, defaulting, or narrowing guidance for state, page_size, or area_query, making the baseline 3 correct.

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

Purpose4/5

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

The description states a concrete use case — showing where RxRooster surfaces anonymous public CRNA service options and approximate U.S. coverage — which is a specific resource, not a restatement of the name. It does not name any sibling tool to differentiate itself from, leaving that contrast to inference, so it falls short of a 5.

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

Usage Guidelines4/5

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

It opens with an explicit trigger ('Use this when an employer asks where...') and then enumerates a long list of what the cards must not be used for (names, contacts, provider counts, price rankings, exact availability). Usage exclusions are unusually explicit, but no alternative sibling tool is named for the excluded cases, so it stops at 4.

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