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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so safety is covered. The description adds valuable negative scoping ('Settings, integrations and the bio are not returned') and identifies the endpoint. It doesn't discuss auth or error behavior, but for a read-only GET that's partially covered by annotations.

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 dense sentences front-load the resource and field list, then add the exclusions and endpoint. Every clause earns its place with zero filler.

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 no-arg read tool with annotations covering safety and no output schema, the description is largely complete: it names the resource, enumerates returned fields, and states what is excluded. The only minor gap is no note on pagination/error handling, but that's low-value for this shape.

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?

Zero parameters, so there is no parameter semantics to convey; per the rules, 0 params baseline is 4. The description correctly implies a no-arg call by not mentioning any inputs.

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 practitioner/API user behind the connection) and enumerates exactly what fields it returns: id, name, title, timezone, default currency, role flags, and practice id/name. It also names the HTTP endpoint, making the mapping unambiguous and distinguishing it from siblings like get_client or list_practitioners.

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 is clear that this returns the authenticated caller's own account via the connection, not an arbitrary practitioner. It does not explicitly state when-not-to-use or name an alternative, but the framing ('behind this connection') effectively constrains usage. No explicit exclusions beyond the field-level negatives.

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