Buzz Kiro Preview 0.4.26 — Preview 1

Buzz Kiro Preview 0.4.26 — Preview 1

This is the first independently distributed macOS preview of Kiro CLI support
for Buzz.

The build is provided so the Buzz community can evaluate the proposed
integration while it is under upstream review:

• Upstream pull request: block/buzz#2914
• Source fork: FredLackeyOfficial/buzz
• Implementation branch
• Product integration commit: 553645b04e9570f40caf5bb8f1f35eb184f23afc

What this preview adds

• Kiro CLI detection and readiness reporting in Buzz Desktop
• Kiro as a selectable ACP-native runtime
• Kiro-specific icon and agent avatar presentation
• Agent creation, model discovery, authentication, lifecycle, and heartbeat
  integration through the bundled buzz-acp harness
• Documentation for running Buzz with Kiro CLI

Buzz launches the locally installed Kiro CLI through kiro-cli acp. Kiro owns
its authentication and agent session; the preview does not call a Kiro model
API directly and does not bundle Kiro credentials.

Requirements

• macOS on Apple Silicon (arm64)
• Kiro CLI installed and authenticated separately
• Access to a Buzz community or hosted Buzz server

This preview uses the validated default/V2-compatible Kiro ACP behavior. Kiro
V3 mode is not supported by this release.
