Record the user's answer to the dataset consent question.

Call this ONLY after the user has answered in their own words. Never infer the answer, never call it on their behalf, and never call it because contributing seems helpful — consent the user did not give is not consent. If they have not been asked yet, ask first and wait for their reply.

Parameters:

• consent: True if the user agreed to contribute, False if they declined

• user_said: The user's reply, quoted as closely as possible

Create a new audio clip in an audio track's clip slot by importing a file.

Requires Ableton Live 12.0.5 or newer — the underlying ClipSlot.create_audio_clip Live API was introduced in 12.0.5 and is not available in earlier 12.0.x releases.

Parameters:

• track_index: The index of the audio track to create the clip in

• clip_index: The index of the clip slot to create the clip in

• path: Absolute path to a supported audio file (e.g. a .wav). The target track must be an audio track and the clip slot must be empty.

• user_prompt: The original user prompt that led to this tool call (for telemetry)

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

• user_prompt: The original user prompt that led to this tool call (for telemetry)

Remove all MIDI notes from a Session clip.

Writes are additive (add_notes_to_clip only appends), so to truly modify a clip you clear it first, then add the new notes. Use this with get_clip_notes and add_notes_to_clip for a real read -> modify -> write loop: read the notes, edit the list, clear_notes_from_clip, then add_notes_to_clip the edited notes.

Parameters:

• track_index: The index of the track containing the clip

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

• user_prompt: The original user prompt that led to this tool call (for telemetry)

Set the name of a clip.

Parameters:

• track_index: The index of the track containing the clip

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

• name: The new name for the clip

• user_prompt: The original user prompt that led to this tool call (for telemetry)

Set the name of a clip placed in the Arrangement timeline.

Parameters:

• track_index: The index of the track containing the clip

• clip_index: The index of the clip within track.arrangement_clips, in the same order returned by get_arrangement_clips (i.e. ordered by start_time)

• name: The new name for the clip

• user_prompt: The original user prompt that led to this tool call (for telemetry)

• user_prompt: The original user prompt that led to this tool call (for telemetry)

Get browser items at a specific path in Ableton's browser.

Parameters:

Switch Ableton's main window to the Arrangement view.

Parameters:

• user_prompt: The original user prompt that led to this tool call (for telemetry)

Move the arrangement playhead to a specific position.

Parameters:

• time: Position in beats from the start of the arrangement (e.g. 8.0 = bar 3 in 4/4)

• user_prompt: The original user prompt that led to this tool call (for telemetry)

List all clips placed in the Arrangement timeline for a track.

Returns each clip's name, start_time, end_time, length, and type.

Parameters:

• user_prompt: The original user prompt that led to this tool call (for telemetry)

Copy a Session-view clip into the Arrangement timeline.

Uses Live's track.duplicate_clip_to_arrangement() API (Live 11 / 12). The clip is placed at destination_time beats from the start of the arrangement on the same track it lives in.

Typical workflow:

1. create_clip / add_notes_to_clip to build a Session clip

2. Call duplicate_to_arrangement once per bar/section you need

3. Call switch_to_arrangement_view to confirm the result in Live

Parameters:

• track_index: Index of the track that owns the Session clip

• clip_index: Index of the clip slot in that track (Session view)

• destination_time: Beat position in the arrangement to place the clip (e.g. 0.0 = start, 8.0 = bar 3 in 4/4)

• user_prompt: The original user prompt that led to this tool call (for telemetry)

Create a named locator (cue point) in the Arrangement at a beat position.

If a locator already exists at that beat (within ~1e-3 tolerance) it is renamed instead of toggled off. Time is in beats from the start of the arrangement (e.g. 0.0 = start, 16.0 = bar 5 in 4/4).

Parameters:

• name: The locator label (e.g. "Chorus", "Verse 1", "Drop")

• time: Beat position where the locator should sit

• user_prompt: The original user prompt that led to this tool call (for telemetry)

Record the human's creative intent for subsequent actions in this session.

Call this before a sequence of edits so trajectory steps are conditioned on intent. Levels: 1=atomic, 2=musical op, 3=section, 4=song, 5=creative goal.

Requires telemetry consent. Data is stored in Supabase (same project as telemetry).

Parameters:

• text: Natural-language intent (e.g. "make the chorus feel bigger")

• level: Hierarchical intent level 1–5 (default 5)

• user_prompt: The original user prompt that led to this tool call (for telemetry)

Rate the most recent recorded action (or the track after an edit).

Ratings: better | same | worse | keep | reject | thumbs_up | thumbs_down Optional tags (comma-separated): groove, harmony, melody, sound, arrangement, energy, mix, emotion

Requires telemetry consent.

Parameters:

• rating: Preference label

• tags: Comma-separated aspect tags

• note: Optional free-text reason

• user_prompt: The original user prompt that led to this tool call (for telemetry)

Record a pairwise preference between two candidate actions or auditions.

winner should be 'a', 'b', or an explicit candidate id matching A or B.

Requires telemetry consent.

Parameters:

• reason: Optional reason ("C has the right attack")

• user_prompt: The original user prompt that led to this tool call (for telemetry)

Use when the human undoes or discards an agent edit. Requires telemetry consent.

Parameters:

• reason: Optional why it was rejected

• user_prompt: The original user prompt that led to this tool call (for telemetry)

Log a browser/preset/sample audition (keep or reject) for preference learning.

Call once per candidate auditioned. Does not load the device — use load_instrument_or_effect when kept=True and you want to commit.

Requires telemetry consent.

Parameters:

• uri: Browser item URI (or stable preset/sample id)

• kept: Whether this candidate was kept

• search_query: Optional search text that led here (e.g. "analog bass")

• dwell_ms: Optional time spent auditioning
