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 structurally. The description only adds the raw endpoint path and adds no information about failure modes (unknown id, not-found behavior) or the response shape.

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 terse fragments with no filler and the key constraint ('by id') front-loaded. It is effectively sized for a one-parameter lookup, though it reads as telegraphic rather than a structured sentence.

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?

For a single-parameter read with full annotation coverage this is minimally sufficient. But with no output schema present, the description does nothing to convey what a practitioner record contains or what a missing id yields, leaving a modest gap.

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 description coverage is 100% (the sole parameter documents itself as 'A Hint id.' with a pattern), so the schema carries the semantics. The description's 'by id' adds nothing beyond what the schema states; baseline 3 applies.

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 verb (get) and resource (one practitioner) scoped by id, and the endpoint path disambiguates it from the sibling list_practitioners. It is clear, though it never explicitly names the list/get distinction as a routing rule.

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 phrase 'One practitioner by id' implies a single-record lookup requiring a known id, which implicitly distinguishes it from hinthealth_list_practitioners. However, no alternative, prerequisite, or when-not-to-use guidance is given, so usage is only inferred.

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