tp_create_library

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

No annotations are provided, so the description must convey behavioral traits. The description only indicates creation, but does not mention mutability, idempotency, error scenarios, or side effects (e.g., whether duplicate names are allowed).

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 very concise (single sentence) and front-loaded. However, it is under-specified and does not earn its place by providing useful information beyond the tool name and title.

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?

Given the lack of output schema, annotations, and minimal parameter details, the description is incomplete. It does not explain return values, error handling, or any behavioral aspects, leaving significant gaps for the agent.

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 covers 50% of parameters with descriptions (only 'athlete' is described). The tool description adds no additional meaning beyond the schema; it does not clarify that 'name' is the folder name or specify any constraints.

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 ('Create') and the resource ('a workout library folder'). It is specific to creating a library, not a workout or other entity. However, it does not differentiate from sibling tools like 'tp_create_workout' beyond the resource type.

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 on when to use this tool versus alternatives like 'tp_get_libraries' or 'tp_delete_library'. No prerequisites or context are provided, such as the need for authentication or the fact that libraries organize workouts.

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