get_user_settings

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only lists settings categories and never explicitly states that the operation is read-only, what the response shape will be, or what units or formats the values use. The 'get' in the tool name implies retrieval, but the description itself adds little behavioral transparency.

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 extremely compact with no filler words and the resource is front-loaded. It is slightly fragmentary as a colon-list rather than a complete sentence, but it is appropriately concise for a zero-parameter settings getter.

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 zero-parameter tool with no output schema and no annotations, the description names four concrete setting domains, which gives an agent a reasonable idea of what to expect. However, it does not define the exact return structure, units, or how this differs from overlapping sibling tools, so completeness is only partial.

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, so the baseline for this dimension is 4 regardless of the description. The description does not need to explain parameter semantics, and the content list adds minor context about what the returned settings cover.

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 identifies the resource as 'user settings' and enumerates the key content areas: VO2Max, thresholds, measurement system, and sleep times. It is not a tautology, but it does not use a full verb and does not distinguish itself from overlapping sibling tools like get_garmin_scores or get_user_profile.

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?

There is no guidance about when to use this tool versus the many sibling getter tools. The description never mentions alternatives, exclusions, or a decision rule such as 'use get_user_profile for user identity information'.

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