Overview

aisync is a command-line tool that gives Claude Code, Codex and Cursor one shared hub on your machine, a local git repository in ~/.ai-sync. Before an agent edits files it claims them, and if another agent already holds a claim on those files the command fails, so the second agent stops before a collision. Decisions, blockers and commits go into one hash-chained journal, and hooks tell a running session what the other tools just did. It also keeps a shared rules block in sync across each tool's own rule file and can write everything to a static status page. You get agents that don't edit the same file at once, plus a record of who did what.
