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 the returned field list, which is mild behavioral value, but says nothing about not-found behavior or id validity, which would matter for a lookup tool.

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 telegraphic fragments with zero padding and the key information front-loaded. It is terse to the point of being clipped, but nothing is wasted.

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's field list (name, NPI, roles) usefully tells the agent what comes back. It omits error/not-found handling and id provenance, leaving a simple lookup tool only adequately specified.

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 0%, so the description must carry parameter meaning; it only says 'by id', which barely maps to user_id and adds no format or sourcing guidance. With one required parameter and no schema-level prose, this is thin.

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+resource ('One user by id') and enumerates the returned fields (name, NPI, roles), so the agent knows this fetches a single practitioner. It only implicitly distinguishes itself from the sibling list_practitioners via the word 'One' rather than naming it.

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?

No when-to-use guidance, no mention of when to prefer this over akutehealth_list_practitioners or akutehealth_search_patients, and no prerequisites (e.g. whether the caller must already know the id). Usage is only inferable from the name.

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