create_group_track

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

No annotations are provided, so the description carries full burden. It only states that a group track is created, but does not disclose side effects, prerequisites, whether original tracks are modified or moved, or any constraints. This is similar to the 'Update shared drive settings' example which scored 2 for lacking permissions/reversibility.

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: one sentence for purpose plus a two-item parameter list. It is front-loaded and every line adds value, especially given no schema descriptions exist.

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 creation tool with two parameters and no output schema, the description covers the basics but lacks behavioral context such as track order, prerequisites, or side effects. It is more complete than a mere tautology but not as rich as the get_calls example.

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 0%, so the description must compensate. It explicitly explains both parameters: track_indices as list of indices to group and name as the group track name. This adds meaning beyond the raw schema types, though it could include details like zero-based indexing.

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 verb 'Create' and the resource 'group track', specifying it contains the specified tracks. This distinguishes it from sibling tools like create_audio_track or create_midi_track.

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 use when you want to group existing tracks into a group track, but it does not explicitly mention alternatives or when not to use. Sibling tools such as ungroup_tracks suggest the opposite operation, but no direct guidance is given.

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