Get Device Settings

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

The annotations already declare readOnlyHint: true and openWorldHint: true, so the safety profile is established. The description adds no further behavioral context beyond the action (get settings), which is consistent with read-only. No contradictions or additional useful details are provided beyond what annotations already cover.

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, compact sentence with no filler or redundancy. It is front-loaded with the action and resource, making it efficient 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?

For a simple getter tool with one parameter, no output schema, and read-only annotations, the description is adequate. It covers the essential purpose and parameter. It could benefit from mentioning what kinds of settings are returned, but that is not critical for tool selection or basic invocation.

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 100%: the only parameter deviceId has a clear description ('The device identifier (required)'). The description's phrase 'specific Garmin device' adds no new meaning beyond what the schema already conveys. It meets the baseline for high schema coverage without adding extra 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 clearly states the action (get), the resource (settings), and the scope (a specific Garmin device). It effectively distinguishes this tool from siblings like get_devices (list devices) and get_primary_training_device (primary device selection).

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 the use case: retrieve settings for a given device identified by deviceId. It does not explicitly mention alternatives or exclusions, but the context is clear given the tool's simplicity and the sibling list. It provides sufficient clarity for when to invoke this tool.

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