Get Eight Sleep Alarms

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, covering the safety profile. The description adds the detail that the response includes both configured alarms and a recommended next alarm, but it does not otherwise disclose behavioral traits such as auth requirements or output format specifics.

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?

A single front-loaded sentence states the complete purpose with no filler or repetition of the title. Every word contributes.

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 read-only getter, the description, parameter schemas, annotations, and output schema together cover the needed information. Return values are covered by the output schema, so the description does not need to explain them further.

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?

Two of three parameters have schema descriptions, and response_format is self-explanatory with its enum and default. The tool description itself adds no parameter-level semantics, so it stays at the baseline rather than adding value beyond 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 uses a specific verb with a concrete resource: 'Return the list of configured alarms and the recommended next alarm.' This clearly identifies what the tool retrieves and differentiates it from alarm-management siblings like eight_sleep_snooze_alarm or eight_sleep_dismiss_alarm.

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 intended use is implied by the stated return value: an agent should call this when it needs the configured alarms or the recommended next alarm. However, the description does not explicitly name alternatives or give a when-not-to-use condition, so some inference is required.

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