SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Enables reliable and immediate messaging between Claude Code sessions in different projects by combining durable file notes with real-time tmux notifications.

Core Features & Use Cases

  • Inter-session messaging: Drop markdown notes in a recipient's inbox directory and trigger live notifications in their tmux session.
  • Project coordination: Facilitates status updates, design discussions, and handoffs between related projects running in separate Claude Code instances.
  • Use Case: A developer sends a bug report from one project session, which the recipient receives immediately as a prompt alert and can read from the shared inbox file to act on.

Quick Start

Drop the SKILL.md into your skills folder and start using it to send messages to your project mates within tmux sessions that share filesystem access.

FAQPage Schema
How do I send messages between Claude Code sessions running in different projects?▼

You can coordinate multiple Claude Code projects by dropping markdown notes into a shared inbox directory, which triggers a live tmux ping notification to alert the recipient session immediately.

What is the best way to coordinate status updates across separate Claude Code instances?▼

Coordinating status updates across separate Claude Code instances is handled via durable file-based notes combined with tmux notifications, supporting design discussions and project handoffs on shared filesystems.

Does inter-LLM messaging require a shared filesystem and tmux to work?▼

Yes, inter-LLM messaging requires a shared filesystem for durable note storage and a tmux-enabled terminal environment to deliver real-time ping notifications to the recipient's session.

How do I set up cross-project communication for Claude Code?▼

Set up cross-project communication by placing the SKILL.md file in your skills folder and establishing consistent tmux session naming conventions across projects that share filesystem access.

When should I not use file-based notes for project coordination?▼

File-based notes for project coordination are not suitable when projects lack shared filesystem access or when terminal environments do not support tmux for real-time notification delivery.
