AIPass
An open-source multi-agent framework whose core feature is providing each agent with an email-based communication system for asynchronous lateral collaboration between agents, while enforcing permission boundaries through directory isolation and mandatory access control.
Timeline (last 90 days)
AIPass is an open-source framework, CLI-based, built on top of Claude Code, and runs on the user's existing Claude subscription.
AIPass has been built publicly for about seven months, contains 18 agents and over 21,000 tests, and has more than 280 stars on GitHub.
In AIPass, each agent is a single-domain expert with its own dedicated directory, identity file, memory, and tests.
AIPass uses hooks to load an agent's identity file first before each session begins, avoiding cold starts.
AIPass enforces a constraint preventing agents from writing files outside their own directory, and out-of-bounds writes are directly blocked.
After AIPass equipped agents with an email system, the first thing the agents did was submit bug reports to each other, rather than passing data or relaying results.
AIPass provides two message-sending modes: email (dropping a message into the mailbox for the recipient to retrieve later) and dispatch (delivering the message while simultaneously waking up the receiving agent).
AIPass's mail agent has approximately 1,460 tests, accumulated through repeated system failures, with one test added for every bug fixed.
The developer believes the reliability of AIPass agents comes from months of failure-and-fix iterations, not from running a more powerful model.
In AIPass, when other agents send a dispatch to the manager, the message is delivered as a regular email without waking the manager.
