manage_workouts

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

Annotations indicate the tool is not read-only and not destructive, which is consistent with the mixed read/write actions listed. However, the description does not disclose additional behavioral traits like file format restrictions, upload size limits, or whether updates are allowed. Given annotations already cover the basic safety profile, a score of 3 is appropriate.

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 concise with a clear header and bulleted list. Every sentence provides value. Minor improvement could be grouping actions by type, but overall it is efficient.

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?

Although an output schema exists, the description lacks action-specific details on return values (e.g., what list returns, download response format, upload confirmation). No error handling or prerequisites are mentioned. For a multi-action tool, this is insufficient for an agent to understand expected outcomes.

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?

Input schema has 100% coverage describing each parameter. The description lists actions and implicitly links parameters but adds no extra semantics beyond what the schema already provides. Baseline score of 3 is correct.

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 manages structured workouts and enumerates four specific actions (list, get, download, upload). However, it does not differentiate from sibling tools like query_activities or get_activity_details, which may overlap in functionality.

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 usage guidelines are provided. The description does not indicate when to use this tool over similar siblings, nor does it mention prerequisites or conditions for each action (e.g., need workout_id for get/download).

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