Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Event Bus Skill ## Version **Version:** 1.0.0 **Status:** OPERATIONAL ## Overview Event Bus provides a centralized event-driven communication system for agent coordination, system events, and lifecycle tracking. Built on the QEEventBus architecture, it enables decoupled, asynchronous messaging between agents and system components. ## Features - Event Publishing and Subscription - Agent Lifecycle Tracking - Event Filtering and Statistics - Type-Safe Event Handling - WASM JSON Integration (Placeholder) ## Core Components ### 1.

How to install
mdr add masharratt/claude-flow-novice/cfn-event-bus@sha256:a956247d9827b75fThe line at the top of this page pins the label git:20260725.c9691fc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
