duplicate_track

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

No annotations are present, so the description carries the full burden. It discloses the core operation (duplicate) and insertion position, but does not mention any side effects, error handling, or permission requirements. This is adequate for a straightforward mutation but lacks depth.

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 concise with two short sentences. The first sets the action, the second adds a specific detail. No unnecessary words.

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 simple tool with one parameter and an output schema, the description covers the core function but lacks parameter explanation and broader usage context. It is minimally complete but could be improved by explaining the parameter and providing a example or note on track indexing.

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 input schema has a single parameter 'track_index' with 0% description coverage, and the tool description does not explain the parameter at all. The field name implies the track to duplicate but does not clarify the meaning of the integer index or any constraints. Description should compensate for missing schema descriptions.

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 'Duplicate a track' using a specific verb and resource, and adds the precise behavior that the copy is inserted directly after the original, distinguishing it from any other operation in the sibling list.

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 implies usage (when you want to duplicate a track) but provides no explicit when-to-use guidance or alternatives. Given no other duplicate tool exists, it is adequate but lacks context for prerequisites or exclusions.

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