Reacts in real time
It's not a playlist. Every note is generated from what your agent is actually doing right now — reading, running, editing.
Open-source Cursor extension · built on Strudel
Your agent is vibing.
Your agent is vibing.
Now you can hear it.
Agent Vibes turns your AI agent's progress into live, generative music. Reads, runs, fails, ships — and it all becomes a film score for your code.

The idea
Watching an agent work is oddly tense.
Watching an agent work is oddly tense.
So we scored it.
You fire off a prompt, then watch a wall of text scroll by as the agent reads, runs, edits, and finally answers. Agent Vibes reframes that wait as a performance — the dramatic arc of a run mapped onto a piece of music that breathes with the work.
- Idle Session open. An ambient drone — nothing happening yet.
- Prompting You submit a prompt. Energy stirs.
- Thinking The agent reasons. Subtle layers fade in.
- Working Tools fire — reads, shells, edits. Bass and kick build, tempo lifts.
- Tension A tool fails. A dissonant swell rises.
- The drop The agent streams its answer. The lead hits the climax.
- Resolve The run stops. Everything winds down to calm.
Scenes
One run, four moods.
The same agent state, rendered four ways. Pick one and the whole page — and the live demo above — tunes to it. Each session also rolls a fresh key and mode, so it never repeats.
How it works
Three signals, one conductor, live audio.
Agent Vibes listens to what Cursor is doing, distills it into three smoothly-interpolated parameters, and hands them to a Strudel program that re-synthesizes itself as the run unfolds.
Transcript + hooks + your typing feed the Conductor, which holds three eased parameters — intensity, tension and tempo — and hands them to Strudel, which re-synthesizes the music live.
Tension & release
Failures create suspense; long silences build dread. When the answer finally streams, the music drops.
Four switchable scenes
Cinematic, techno, lo-fi, chiptune — change the entire mood live, mid-run, from the panel.
Reacts to your typing experimental
Typing in files becomes gentle pulses. Experimentally (macOS), even the prompt you're composing mixes the music.
Synthesized & offline
No samples, no streaming, no accounts. Every drum and synth is built in the browser, so it works with no network.
Generative & fresh
Each session rolls a random key and mode, so a scene keeps its identity but never sounds exactly the same twice.
Live visual feedback
Meters, a VU output, a rhythm view and a color-coded event feed show exactly what's driving the sound.
Open source (MIT)
Scenes are just code that maps agent state to music. Fork it, tune it, or write a scene of your own.

Agent Vibes is an early V1 scaffold — honest about it. It's developer-installable from source today; the cinematic scene is the most developed while the others are being tuned.
$ git clone https://github.com/agent-vibes/agent-vibes.git
$ cd agent-vibes
$ npm install
$ npm run build

Launch in Cursor
Press F5 to open an Extension Development Host window.

Start a Jam
Run “Agent Vibes: Start Jam” to open the panel beside your editor.

Enable audio
One click — required once by the browser's autoplay policy.

Wire the hooks
Auto-installed for failure/stop cues. Start a fresh agent chat.

Give it a task
Hand the agent some work, sit back, and listen to it build.
Heads up: the “react to what you type in the chat box” feature is experimental and macOS-oriented, and Agent Vibes is tuned for Cursor's transcript and hooks. It's young — and that's the fun part.
