add_notes_to_clip

Add MIDI notes to a specific clip in Ableton Live by specifying the track, clip, and a list of note properties including pitch, timing, and velocity.

Instructions

Add MIDI notes to a clip.

Parameters:

  • track_index: The index of the track containing the clip

  • clip_index: The index of the clip slot containing the clip

  • notes: List of note dictionaries, each with pitch, start_time, duration, velocity, and mute

Behavior2/5

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

The description does not disclose important behavioral traits such as whether notes are appended or overwritten, whether there are limits on note count, or if adding notes affects playback. With no annotations available, this is a significant gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is brief and gets straight to the point, but the parameter list could be more structured (e.g., formatted separately). It is front-loaded with the main action, making it easy to scan.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of annotations and output schema, the description covers the essential purpose and parameters, but is incomplete on behavioral aspects (e.g., append vs. overwrite, error handling). It is adequate for basic usage but not comprehensive.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 0% coverage, but the description provides clear explanations for each parameter, especially 'notes' by listing its subfields (pitch, start_time, etc.). This adds substantial meaning beyond the schema's minimal type constraints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Add MIDI notes') and the resource ('clip'). It effectively distinguishes this tool from siblings like 'create_clip_with_notes' (which creates both clip and notes) and 'remove_notes_from_clip' (which removes notes).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. It does not mention prerequisites (e.g., the clip must exist and be a MIDI clip) or when not to use it.

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