garmin_training_status

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

No annotations are present, so the description carries the burden of behavioral disclosure. It lists the data fields but does not explicitly state that it retrieves/returns data or how the optional date affects the result. It is not misleading, and for a read-only status tool the risk is low, but behavior remains mostly implied.

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?

The description is a compact phrase with no filler; every listed metric is relevant and informative. It could be improved by adding a verb and making it a complete sentence, but the structure is efficient and front-loaded.

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 a single optional parameter, full schema coverage, and an output schema present, the description does not need to be long. It provides enough distinct information for an agent to select this tool among the Garmin siblings. An explicit verb and usage note would make it fully self-contained, but the current level is adequate.

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 only parameter, date, is already fully documented in the schema with ISO date format and a default of today. The description adds no parameter-level detail, and with 100% schema coverage, the baseline of 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?

The description identifies a specific domain and lists distinctive metrics (acute/chronic load, ACWR, load focus, VO2 max) that clearly separate it from sibling Garmin tools like garmin_recovery or garmin_performance_metrics. It lacks an explicit verb such as 'retrieves' or 'returns', but the intended purpose is still unambiguous.

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 metric names imply this tool is for training status and load-related queries, giving some usage guidance. However, there is no explicit when-to-use / when-not-to-use guidance and no mention of alternatives, so the agent must infer the boundary against the many sibling tools.

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