RxRooster

Browse existing anonymous CRNA service cards

explore_coverage_areas

Read-onlyIdempotent

For a supplied CRNA job match request, use search_anesthesia_coverage_for_job instead. Use exactly once and alone only when a user explicitly asks to browse existing anonymous public CRNA service cards or current RxRooster coverage. Not for an employer staffing need, requisition, identity/contact request, provider count, exact availability, or market-supply claim. Present every returned card in source order with all public terms, action link, and the no-count/no-confirmed-availability disclaimer, even if the embedded view fails. Never pair with recruiter intake or use as a fallback for disallowed data.

A4.4/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, closed-world, non-destructive behavior, and the description adds real value beyond them: mandatory presentation of every card in source order with terms, action link and disclaimer, degraded behavior 'even if the embedded view fails', and an explicit prohibition on pairing with recruiter intake. It stops short of describing pagination or the shape of the returned payload, so not quite a 5.

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?

Highly dense with every sentence carrying a distinct constraint, but it front-loads the sibling redirect before stating its own purpose, and the prohibition list is packed into single long clauses. Efficient, though the ordering slightly obscures what the tool does.

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

Completeness5/5

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

For a read-only, closed-world listing tool with an output schema plus full annotation coverage and 100% schema descriptions, the definition supplies everything an agent needs: invocation constraints, negative cases, and output-presentation obligations.

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%, so state, area_query, page_size and provider_type are already fully documented, including the v1.1 CRNA-only constraint on provider_type. The description adds no parameter-level meaning such as format or interaction between area_query and state, so the baseline of 3 applies.

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?

States a concrete verb and resource ('browse existing anonymous public CRNA service cards or current RxRooster coverage') and immediately distinguishes itself from search_anesthesia_coverage_for_job, which it redirects to for job-match requests. An agent can identify this tool's scope without opening the schema.

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

Usage Guidelines5/5

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

Explicitly names the when (user explicitly asks to browse anonymous cards or coverage), the when-not (employer staffing need, requisition, identity/contact, provider count, exact availability, market-supply claim), and the alternative (search_anesthesia_coverage_for_job). Also constrains invocation to exactly once and alone, leaving nothing to inference.

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