get_device_alarms

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

The description uses 'Get' and 'Returns', indicating a read-only operation, but it does not explicitly disclose side effects, rate limits, or pagination behavior. Since no annotations are provided, the description carries the burden and is somewhat minimal but not misleading.

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 short and to the point, consisting of two concise sentences. It avoids unnecessary detail and is well-structured for quick comprehension.

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, the description does not need to explain return values in depth, but it does provide a helpful summary of the alarm attributes (schedules, sounds, enabled status). It lacks any mention of authentication or potential limitations, but these are not critical for a straightforward getter.

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 tool has zero parameters, and the schema coverage is 100% (vacuously). The description does not add parameter information because none exist, which is consistent with the baseline for high schema coverage.

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 tool's purpose with a specific verb ('Get') and resource ('alarms from all Garmin devices'), and it specifies the returned data (schedules, sounds, enabled status). No sibling tool appears to handle alarms, so there is no ambiguity.

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 implies usage for retrieving alarms but does not explicitly state when to use it versus alternative tools. However, since there is no other alarm tool among the siblings, the necessity is implicit. It lacks explicit when-to-use/when-not-to-use guidance.

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