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

No annotations are provided, so the description carries the full burden. It mentions data source and refresh frequency but lacks details on pagination, sorting, rate limits, or any constraints. The read-only nature is implied but not confirmed.

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 plus a source/price note, with no redundant words. It is front-loaded with the tool's purpose.

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?

Without an output schema, the description should hint at return fields. It answers the question of which facilities meet thresholds, implying quality metrics and names, but does not specify columns or data structure. Adequate but not thorough.

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 coverage is 0%, meaning no parameter descriptions. The description explains four of seven parameters (city, state, zip_prefix, rating_min/max) but omits limit and offset, and does not clarify how rating range works or default values.

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 'dialysis quality data', specifies search criteria (state, city, ZIP, star rating), and answers a concrete question. It is well-differentiated from sibling carecompare search tools for other provider types.

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 clear context (search by location/rating to find quality thresholds) but does not explicitly mention when to avoid using it or compare with sibling carecompare_dialysis_byCcn for CCN lookups. Still, the purpose is well-defined.

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