Does this require a real Erlang VM?

No, it uses Bash scripts and the /tmp directory to simulate the actor model behavior within any standard shell environment compatible with Claude.

Does it support pattern matching?

Yes, it supports glob-based pattern matching on sender IDs, allowing for selective message consumption similar to Erlang's native receive blocks.

Is it suitable for high-performance production systems?

No, it is primarily designed for simulation, testing logic, and coordinating scripts within an AI-driven development workflow rather than for high-throughput production IPC.

How are messages delivered?

Messages are written as JSON files to specific directories acting as mailboxes. Receiving processes poll these directories until a matching message is found or a timeout occurs.

What is Erlang Message Sync?

It is a skill for Claude Code that replicates Erlang's message-passing behavior using a filesystem-based mailbox system for process synchronization.

Developer Tools

Implements Erlang-style actor model message passing using the filesystem to synchronize parallel processes and simulate distributed systems.

About

This skill provides a robust framework for simulating Erlang-style message-passing semantics within the Claude environment by utilizing the /tmp filesystem as a message transport layer. It enables true asynchronous sending and blocking receive primitives, complete with pattern matching and timeout handling, allowing developers to model complex actor-based architectures. It is an essential tool for architecting distributed systems, testing concurrent logic, or coordinating multi-process workflows where reliable message delivery and synchronization are required for simulation.

Key Features

Blocking receive primitives with customizable timeout support
JSON-formatted message persistence for reliable data exchange
Automated message cleanup upon successful receipt to manage mailbox size
0 GitHub stars
Asynchronous message delivery via filesystem-based mailboxes
Selective message consumption using glob-based pattern matching

Use Cases

Coordinating multi-process background tasks with real-time synchronization
Simulating and testing distributed actor-model architectures and protocols
Verifying message ordering and race conditions in concurrent logic simulations
