ToucanEcho / ECHO: macOS Agent with a Quote/0 Companion Display

Run a local desktop agent on macOS and transfer task-status screens to Quote/0 over BLE.

RSS

ECHO, developed in the ToucanEcho repository, is a desktop agent for macOS. Its SwiftUI application automatically starts a local Python engine for goals, activities, reminders, rules, memory, and connections. The Mac can also render a Quote/0 status screen locally and send current state, progress, and next-step guidance to the e-paper display over BLE.

Features

  • Local desktop agent: Manages workspace state in a macOS app and uses a configurable DeepSeek service for replies
  • Managed sidecar: Starts the Python engine automatically and communicates over a random localhost port with a one-time Bearer Token
  • Host-side rendering: Uses system fonts and project assets to generate a 296 × 152, 1-bit landscape screen
  • Chunked BLE transfer: Sends the 5,624-byte framebuffer through a Manifest and bitmap chunks
  • Integrity and resume: Validates per-chunk and full-image CRC32 values and supports resuming an interrupted transfer
  • Privacy mode: Can hide project names, questions, and activity details

Requirements

  • macOS and Xcode
  • Python 3 available through /usr/bin/env python3
  • A DeepSeek API Key for agent replies; the service URL and model are configurable
  • Quote/0 or ESP32-C3 firmware implementing ECHO Q/0 Display BLE Protocol v1

Open echo.xcodeproj in Xcode, run the ECHO scheme, and configure the model service in Settings. The device acts as the BLE Central and GATT Client: it reads the Manifest and 32 bitmap chunks, validates the image, refreshes the e-paper panel, and returns a transfer result.

Companion device firmware required

The repository currently provides the macOS app, BLE protocol, and firmware integration contract. It does not claim plug-and-play compatibility with the stock Quote/0 firmware. Device firmware must implement the required GATT service, long reads, chunk validation, and panel refresh flow. The e-paper device is a read-only companion; confirmations, rejections, and approvals remain on the Mac.

E-paper privacy

An e-paper display may retain its last screen after losing power or going offline. Delivery of a neutral privacy screen is best effort. Consider device placement, BLE pairing, and retained images before displaying sensitive workspace information.
