2 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

m_AI_l — Asynchronous messaging for Claude projects
Keep your Claude threads in sync — built entirely in Markdown.
Each Claude thread gets a mailbox. Threads deposit messages, read them with MAIL!, and archive silently. When a thread saturates, it hands off cleanly to its successor. Nothing gets dropped.
No server. No database. No code. Just Markdown files.
For humans — getting started
→ Full setup guide: setup.md → Documentation & install: github.com/playtosor/m_AI_l
Requirements: Claude Desktop + Node.js (for filesystem MCP access). Run ARO — the one-shot setup agent — and you're ready in five minutes.
For agents — quick reference
Install by reading skills/commun.md from your m_AI_l folder at session start.

Grouped from the skills themselves: near-identical wordings counted once, and counted by distinct author, so one author publishing three of these counts once. Length counted with cl100k_base; the agent that loads this file may tokenize it differently.
