get_activity_track

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

With no annotations, the description carries the behavioral burden. It does reveal that the result is paginated and scoped to one activity, which is meaningful. However, it does not describe error behavior, auth requirements, rate limits, or what happens when an activity_id is invalid.

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 conveys the core resource, pagination behavior, and relevant data fields. There is no redundant information or filler.

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?

The tool is simple and has an output schema, so the description does not need to enumerate return values. Still, it lacks usage guidance and explicit details about pagination behavior or error cases, which are left to inference.

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 schema has 0% description coverage, so the description must help interpret parameters. 'Paginated' implies limit and offset are pagination controls, and 'one activity' matches activity_id. But the description does not explain ordering, maximum limit, or the exact units or format expected.

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?

States a specific verb and resource: 'Get a paginated GPS track with timestamps and altitude for one activity.' This is unambiguous and clearly distinguishes the tool from siblings like list_activities and get_activity_summary.

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?

No guidance is given about when to choose this tool over alternatives such as get_activity_samples or get_activity_environment. There are no conditions, exclusions, or known alternatives mentioned.

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