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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds credential scoping (no ID needed) and names the endpoint, but says nothing about error behavior when the key has no practice or about nested/complex fields.

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?

Two short, front-loaded sentences with no filler; the field enumeration earns its place by partially compensating for the absent output schema. The raw 'GET /provider/practice' path is aimed at developers and is the only mildly redundant element.

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?

With no output schema, the description carries the return-value burden and does list the fields returned. It is shallow (no types or structure), but for a zero-parameter, read-only getter with annotations covering safety, it leaves an agent adequately equipped to call it correctly.

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?

The tool takes zero parameters, so the baseline is 4 and there is nothing for the description to disambiguate. The field list it provides relates to output, not input, and does not improve parameter semantics.

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?

States a specific resource ('the practice') and clarifies scope—the one bound to the current API key—then enumerates the returned fields. An agent can tell it apart from siblings like get_location or get_practitioner, though the verb is only implied rather than stated.

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?

Usage is implied rather than stated: zero parameters and the 'this API key belongs to' framing make it clear this is the single, credential-scoped practice lookup. There is no explicit when-to-use or when-not-to-use against the other get_* siblings.

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