Hackathon Edition

Your AI agent's mood, on your desk.

Buddy turns Codex / Claude / Enter session state into a tiny pixel pet on a real device. Glance at the screen, not 12 tabs.

Pet states

Six moods. One glance.

Buddy maps your agent's session signals to expressive pixel states. No reading logs.

Thinking

Agent is reasoning. Pet is curled up, ears twitching.

Busy

Tools are running. Pet sprints across the screen.

Waiting

Approval needed. Pet peeks at you and waits.

Error

Something failed. Pet trips over and looks up.

Done

Task finished. Pet does a little happy dance.

Idle

No activity. Pet curls up and naps.

Why

Codex left a tool-call waiting. You moved on.

Modern AI agents pause for approval, get blocked on errors, and finish silently in the background. Your terminal scrolls past it. Buddy keeps that one signal where you can actually see it — on a 64×64 screen sitting next to your keyboard.

Without Buddy

Approval prompt buried under 200 lines of tool output. You notice 10 minutes later.

With Buddy

Pet is staring at you. You glance over, hit enter, get back to work.

How it works

Three pieces. One pet.

Codex / Claude / Enter

Your AI session, unchanged.

buddy CLI

Watches the session, builds a snapshot.

MQTT

Streams the snapshot to your device.

Pet on device

Renders the matching pixel state.
