add_notes_to_clip

Add MIDI notes to a specific clip in an Ableton Live track by specifying pitch, timing, velocity, and other properties.

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 dicts, each with pitch, start_time, duration, velocity, mute (and optionally probability, velocity_deviation)

Behavior2/5

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

No annotations provided; description lacks disclosure of behavioral traits such as whether notes are appended or overwritten, required permissions, undo behavior, or response format. Minimal transparency.

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

Conciseness5/5

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

Two sentences plus bullet list. Purpose stated upfront, no wasted words. Efficiently structured for quick parsing.

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?

No output schema or annotations. Description covers parameters well but omits success/failure behavior, return value, error handling, and side effects. Adequate but not complete for a mutation tool.

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

Parameters5/5

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

Schema description coverage is 0%, but description fully explains each parameter: track_index, clip_index, and notes with dict structure including required and optional keys, adding significant meaning over schema.

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?

Description clearly states verb 'Add' and resource 'MIDI notes to a clip', distinguishing it from siblings like 'remove_notes_from_clip' and 'get_notes_from_clip'.

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 explicit guidance on when to use this tool vs alternatives (e.g., create_clip, remove_notes_from_clip). No prerequisites mentioned (e.g., clip must exist and be MIDI).

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