AI overview

MaxonT releases aisync 0.2.0, a local hub (located at ~/.ai-sync/, itself a git repository) that lets Claude Code, Codex, and Cursor share rules, logs, and file occupation declarations. Agents claim a file before editing it; when two agents occupy the same file at the same time, the process exits with code 3, thereby avoiding parallel modifications to the same repository. 0.2.0 adds "rules as interfaces, layered loading." Installation can be done via uv, pipx, or pip, and does not modify shell configuration; running requires Python 3.11+ and git, and supports macOS and Linux. After installation, the prompt asking whether to star defaults to "no" and is no longer asked repeatedly, remaining silent in CI, pipelines, and scripts; setting NO_STAR_PROMPT=1 skips the question.

    Show HN: Aisync, advisory file claims so two AI agents don't edit one repo

    aisync is a local hub (~/.ai-sync/, a git repo) that lets Claude Code, Codex and Cursor share rules, a hash-chained journal and file claims, with an overlapping claim exiting with code 3 so an agent stops before colliding. Hooks inject what other tools just did into running sessions, and version 0.2.0 adds layered When/Do/Not rules, a progress_file for stable prompt caching, and an optional MCP server. It requires Python 3.11+ and git on macOS or Linux, uses only the standard library, and is MIT licensed.
