create_midi_track

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

No annotations provided, so description carries full burden. Only states the action and parameter, omitting any side effects, permissions required, or impact on the session. Minimal disclosure beyond the basic creation.

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?

Two sentences, no redundancy. Purpose is front-loaded, parameter explanation follows. Every word earns its place.

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?

Adequate for a simple creation tool with one parameter and an output schema (not shown). However, without annotations, it lacks details on return values, errors, or session state changes. Meets minimum viability but leaves gaps.

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 explains the 'index' parameter meaningfully: 'The index to insert the track at (-1 = end of list)'. This adds context beyond the schema (which only shows default -1), and with 0% schema description coverage, fully compensates.

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?

Clearly states 'Create a new MIDI track in the Ableton session.' The verb 'create' and resource 'MIDI track' are specific, and among siblings like 'create_audio_clip' and 'create_clip', it uniquely identifies creating a track, not a clip.

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?

No guidance on when to use this tool versus alternatives. Does not mention prerequisites, conditions, or cases where other tools (e.g., create_audio_clip) would be more appropriate.

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