Developer source alpha

This is an unofficial community fork of Block's Buzz with first-class support for Cognition's official Devin CLI through devin acp. It is not an official Block or Cognition product.

This prerelease is an immutable, source-only checkpoint for trusted technical testers. No DMG or application bundle is attached. Locally built applications are unsigned and are not intended for redistribution. This is not the signed/notarized public beta.

Supported target for this alpha

  • Apple Silicon macOS 11 or newer
  • Verified on an Apple Silicon Mac mini
  • Intel macOS, Windows, and Linux have not completed fork-specific packaging and live acceptance and are not supported by this alpha

What is included

  • Native Devin ACP runtime using executable devin with default argument acp
  • Runtime readiness states for missing CLI, unauthenticated CLI, authenticated/ready, and ACP startup failure
  • Official Devin CLI installation and devin auth status readiness guidance
  • White-background Devin runtime artwork in the existing Buzz runtime icon system
  • Owner-only invocation and one-worker defaults
  • Fail-closed permissions without dangerous bypass modes
  • Fork-isolated app identity, data directory, Keychain service, Nest, CLI link, and deep-link scheme

This does not claim model switching, Fusion, fan-out, Outposts, cloud handoff, or cloud Devin parity.

Build and install from this exact source

Install and authenticate the official Devin CLI first using Cognition's documentation: https://docs.devin.ai/cli

git clone https://github.com/fenner888/BuzzforDevin.git
cd BuzzforDevin
git checkout buzz-for-devin-v0.4.25-alpha.1
. ./bin/activate-hermit
./scripts/build-buzz-for-devin-macos.sh
./scripts/install-buzz-for-devin-macos.sh \
  "desktop/src-tauri/target/aarch64-apple-darwin/release/bundle/macos/Buzz for Devin.app"

The build script does not sign, notarize, publish, launch, or install the application. Review the complete macOS source-build instructions before proceeding. Do not bypass organizational security policy or redistribute the unsigned local build.

Validation

Exact source commit: e71f175def60dd86d72343738ad4e4fbf65eb69d

  • Focused changed E2E tests: 4 passed
  • Surrounding agent E2E files: 73 passed
  • Desktop formatting, lint, file-size, text-size, and pubkey guards: passed
  • Full fork GitHub CI: passed, including Rust lint, unit tests, security policy, relay E2E, desktop core, macOS build, Windows Rust, mobile, web, desktop smoke shards, and relay-backed integration shards
  • CI evidence: https://github.com/fenner888/BuzzforDevin/actions/runs/30311041449

Known limitations and remaining release gates

  • Signed/notarized DMG is not yet available
  • The updater remains disabled until a fork-owned signing key and HTTPS endpoint are configured
  • Clean-machine acceptance remains required for the signed release
  • Three inherited Apple Silicon dependency maintenance advisories remain documented for explicit release review
  • Revocation takes effect after the managed agent is restarted
  • Revoking a live agent instance and changing its saved definition are separate actions
  • Windows, Linux, and Intel macOS need platform-specific builds and Devin ACP live acceptance before support is claimed

Generic upstream integration is tracked separately in block/buzz PR #3225.
