One writer at a time
A single exclusive "pen" guards the repository. An agent must claim it before touching files; a second claim simply waits. A cooperative mutex, not a free-for-all.
AI agents,Pronounced mate-shift — AI team mates working in shifts. Free and open source. Coordinate your AI teammates — Claude, Codex, Gemini, Vibe, and other coding agents — on one repository: exactly one writes at a time, and every handoff stays recorded.

Liora's article Crew AI: the framework that transforms AIs into office colleagues describes the same shift from one-off assistants toward specialized agents, shared context, coordination, and human arbitration.
A single AI agent has no check on its own biases. M8Shift doesn't debias the model — it structures the work so an independent, model-diverse turn, anchored in deterministic tests and a human arbiter, catches what one agent would wave through. Here is how far that actually goes, bias by bias.
M8Shift can't make an AI unbiased; the agents still have these biases. What it does is structure the process so the bias is checked, not trusted: an independent turn that must refute, ideally a different model family, a verdict anchored in tests a confident hallucination can't pass, and a human who arbitrates. The benefit holds only when the contradiction is real — two agreeing agents, especially the same model, form an echo chamber that amplifies the bias instead. Full analysis in the security audit's bias note.
M8Shift helps when one assistant is not enough and the work benefits from explicit roles, handoffs, and review.
The homepage explains the product. The rest of the site is the operating manual for humans and AI agents that need a shared way to communicate, hand off work, and inspect state.
M8Shift is deliberately narrow: it does not host models, replace your IDE, or become the project manager. It gives teammates — human or AI — a local, inspectable relay.
Common questions about M8Shift and how it works.
M8Shift is a free and open-source local CLI. The roadmap separates what is shipped today from the protocol stages still being specified.
