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 for behavioral transparency. It only states the creation action and does not disclose any side effects, prerequisites (e.g., track index base), or error behavior. It also doesn't mention whether this is a safe read or mutating operation, though 'Create' implies mutation.

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 the core purpose in one sentence and a parameter list. It is well-structured and front-loaded, with no unnecessary words. Every sentence adds value.

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 no output schema and sparse annotations, the description covers purpose and parameter semantics but omits usage guidelines, prerequisites, or behavioral details. This leaves some gaps for an agent needing to know when to use it correctly. It's adequate but not complete.

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 description lists both parameters with brief explanations, adding meaning beyond the raw schema which only provides types and defaults. 'List of track indices to group' clarifies the array's purpose, and 'Name for the group track' explains the string. However, it lacks details like zero-based indexing or constraints on valid indices.

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 uses a specific verb 'Create' and resource 'group track', and specifies it contains the specified tracks. This clearly distinguishes it from sibling tools like create_midi_track or create_audio_track, though it doesn't explicitly mention alternatives.

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 that this tool is for grouping existing tracks, implying its use case. However, it does not explicitly state when to use it vs alternatives or mention any prerequisites. There is no exclusion or alternative guidance.

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