ClawBus is a minimal coordination protocol for multi-agent Claude Code — a trust layer that makes delegation, approval, and audit first-class protocol events instead of UI callbacks. It lowers the trust barrier to multi-agent Claude Code by making every task, approval, and result inspectable after the fact. The itch came from running multiple Claude Code sessions across a 5-node cluster for months: every coordination layer I built reached for workflow engines bigger than needed, while hand-offs still happened by copy-pasting context between tabs and approving diffs on vibes. ClawBus replies with five message kinds (task / result / approval- request / approval-decision / log), an append-only store with causal parent links, and an adapter interface four methods long. Three adapters ship — File, SQLite, Discord; the last lets a human ✅ reaction become an approval-decision without the worker knowing which transport it's on. Same protocol, different transport, identical audit trail. Built on the Claude Agent SDK with Opus 4.7, every file mutation routes through an approval-request — a fully inspectable message carrying the proposed diff, severity, and rationale. The gate doesn't pause on vibes. MIT TypeScript, 27 tests on CI, three captured end-to-end runs auditable in five minutes.
