get_training_readiness

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Get' and mentions components; it does not disclose whether this is a read-only operation, what 'components' means, whether it depends on other data like sleep, how dates are handled, or what the response contains. The description adds little beyond the tool name.

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 single concise sentence that front-loads the core operation and resource. It is efficient and easy to parse, though the phrase 'and its available components' is slightly vague and could be more informative without adding length.

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 one-optional-parameter getter, the description is minimally adequate: the tool name and description together convey what is being retrieved, and the output schema presumably documents return shape. However, it lacks any guidance on date semantics, required prior data, or how this metric relates to sibling tools, leaving noticeable gaps for an agent deciding how to invoke it.

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 should compensate, but it says nothing about the optional 'date' parameter: its format, meaning, default behavior, or how omitting it affects results. The parameter name and nullable default in the schema provide minimal clues, but the description adds no semantic value.

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 verb ('Get') and a specific resource ('Garmin training readiness'), and further notes it returns 'available components.' This makes the tool's purpose reasonably clear and distinguishable from siblings such as get_training_load or get_training_context, though it does not explicitly name any alternative.

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 guidance is provided about when to use this tool versus siblings like get_training_context, get_recovery, or get_hrv. The description relies entirely on the resource name to imply usage, and there is no mention of prerequisites, expected input, or exclusions.

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