Shift

Lightweight coordination layer for multiple AI agents working on the same codebase simultaneously.

Shift provides multi-agent coordination through a check-in/check-out session model where each worker registers with a gist of current work and declared file paths. The server maintains an in-memory worker session store and returns coordination instructions with every interaction, giving each agent awareness of active peers. It supports both stdio and Streamable HTTP transports, runs without external databases or filesystem writes, and resets cleanly on restart.
