Snooze Eight Sleep Alarm

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

Annotations already indicate a mutation (readOnlyHint=false) with idempotent and non-destructive hints. The description adds the prerequisite configuration requirement, which is helpful, but does not elaborate on any side effects or behavior if the alarm is not ringing. No contradiction with annotations.

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 very concise at two sentences, no fluff. However, it may be too brief for a complete understanding; a bit more context on the snooze duration or effect would improve it without becoming verbose.

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 an output schema present, return values are covered. However, the description lacks details on post-snooze behavior (e.g., duration, next alarm) and does not differentiate from the sibling 'dismiss' tool beyond the action verb. Enough to be functional but not optimally complete.

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 coverage is low (33% for alarm_id) and the description adds no additional parameter information. While the required parameter is clear, user_id and response_format are left undefined in the description, failing to compensate for the schema gaps.

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 ('Snooze') and the resource ('actively ringing alarm'), which distinguishes it from sibling tool 'eight_sleep_dismiss_alarm'. The verb and object are 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 clear context for when to use this tool (when an alarm is actively ringing) and requires a specific configuration setting ('EIGHT_SLEEP_ALLOW_MUTATIONS=true'). However, it does not explicitly mention when not to use it or provide alternative tools like dismiss.

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