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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only states 'Get sleep data' without explaining return format, data scope, authentication needs, or any side effects. For a read operation, basic transparency about what 'sleep data' includes is missing.

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 concise at 9 words, front-loading the action and resource. It is efficient but somewhat terse; a minor addition about what 'sleep data' entails would improve utility without sacrificing conciseness.

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?

Given no output schema, the description should hint at the return value (e.g., fields, structure). It only says 'sleep data', which is vague. For a tool with a single parameter and no complex output, this lack of detail makes it incomplete for an agent to fully understand the response.

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 input schema already describes the only parameter ('cycleId') with a clear description ('ID of the cycle to get sleep data for'). Since schema coverage is 100%, the baseline is 3. The top-level description adds no new meaning beyond the schema, so no adjustment is warranted.

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 clearly states the action ('Get sleep data') and the resource ('for a specific cycle'). It effectively distinguishes from sibling tools like 'whoop-get-sleep-by-id' (sleep by sleep ID) and 'whoop-get-recovery-for-cycle' (recovery for cycle). The verb+resource combination is specific and 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 description provides no guidance on when to use this tool versus alternatives such as 'whoop-get-sleep-collection' or 'whoop-get-sleep-by-id'. It does not mention prerequisites, limitations, or scenarios where this tool is preferred, leaving the agent to infer from the name alone.

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