Fusion CLI
A local, conversational control plane that lets several AI coding models propose changes to a repository, while Fusion itself verifies and applies every change only after the user approves its exact bytes.
Fusion classifies each line of a conversation itself, with no model involved: talking, explaining, planning and analysis are read-only turns, and only an explicit change request can lead to a write, which then goes through a verified build-and-delivery route. A build shows its plan, including the task, exact files and verification, before it runs, and a delivery shows a summary of files, verification result, review result and a manifest digest before it can be applied; nothing is committed or pushed automatically.
For small questions it uses one model; for a broad analysis of a large project, a Lead model decides whether to answer directly or delegate bounded investigations to parallel Explorer models, with a separate Reviewer model giving a second opinion, all capped by a budget the host policy enforces.
Its primary host is Windows 11, with writer verification running inside Docker Linux containers; unrestricted autonomous write mode is not enabled.
