create_midi_track

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It merely states the creation action and the index parameter, but does not disclose potential side effects, undo behavior, required permissions, or the effect on existing tracks and session state. This is insufficient for a mutation tool.

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 and front-loaded with the core purpose in the first sentence. The Args section is clear and directly explains the parameter. There is no redundant text.

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 tool's simplicity (one parameter) and the presence of an output schema, the description covers the essential information: what it does and what the parameter means. However, the lack of annotations and absence of any behavioral context slightly limits completeness, though for this simple create action it is largely adequate.

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 only provides a default value and type (integer, default -1), with zero schema description coverage. The description adds meaningful semantics: 'Position to insert the track. Use -1 to append at the end.' This clarifies the role of the index parameter and the special value, going beyond the structured schema.

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 a new MIDI track') and the resource ('in the session'), making it specific and unambiguous. It also differentiates from sibling tools like create_audio_track by explicitly specifying 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 provides no guidance on when to use this tool versus alternatives such as create_audio_track or create_clip. It does not mention exclusions or prerequisites. The only usage context is the parameter explanation, which is not about selection of the tool.

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