Get Activity Intervals

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 mentions the data fields returned but does not state that the operation is read-only, any permission requirements, or potential limitations such as pagination or availability. For a data retrieval tool, this lack of explicit safety or behavioral context is a notable gap.

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, concise sentence that is front-loaded with the main action and details. Every word contributes to conveying the tool's core function without redundancy.

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?

While the description explains what data is retrieved, it lacks an output schema and does not describe the response structure, possible formats, or any additional context like ordering or grouping of intervals. For a simple tool this is adequate, but there are clear gaps in what an agent might need to know.

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 description coverage is 100%, with both apiKey and activityId having descriptions. The tool description adds no extra parameter meaning beyond what the schema already provides, so the baseline score of 3 is appropriate.

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 function: retrieving interval/lap data (power, HR, pace per segment) from a single activity. It uses a specific verb ('Ambil' / retrieve) and a specific resource, distinguishing it from sibling tools like get_activity_streams or get_activity_details.

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 by specifying 'dari satu aktivitas' (from one activity), indicating it is for a single activity rather than bulk operations. However, it does not explicitly name alternative tools or provide exclusions, so it stops short of a full 5.

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