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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false. The description adds security-relevant behavior not captured there: it does not reveal the key value, and verify=True performs an auth check without returning profile data. It does not cover failure behavior or rate limits, so it is strong but not exhaustive.

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 sentences with no wasted wording, and the core status-check purpose is front-loaded. The optional verify behavior is stated immediately after.

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 simple status tool with annotations and an output schema, the description covers what the tool checks and what verify does. It does not describe failure modes or what a failed auth check looks like, but the output schema can carry return-shape details.

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?

With only one optional boolean and 0% schema description coverage, the description carries the burden and mostly succeeds: verify=True is explicitly defined as an authentication check, while the opening sentence implies verify=False only checks configuration. The default is already supplied by the schema.

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 states a specific verification action for GARMIN_PERSONAL_API_KEY configuration and clearly distinguishes an optional authentication check. It also contrasts the verify path with returning profile data, which helps separate it from the many Garmin data-retrieval siblings.

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?

It gives a clear context for use: checking whether the API key is configured and optionally performing an authentication check. It does not explicitly name alternatives or when-not-to-use cases, but the tool's status-check role is distinct from the sibling data endpoints.

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