what is passation- fr?

Passation is a small script that helps you switch between two AI coding assistants, Claude Code and Codex CLI, without losing your place. If one of them stops working partway through a task, because it hit a usage limit, crashed, had its terminal closed, or was interrupted in some other way, you run this script inside the same Git repository, and it writes a single file called passationlive.md that the other assistant can read before picking up the work. The script does not install any hooks, does not change Claude or Codex's configuration, and does not run in the background, it runs once and exits. It works by reading local session files and Git state passively, treating your Git history as the most reliable record of what actually got done. From that, it pulls together things like the four most recent complete prompt and response exchanges, several earlier progress milestones from the session, how long the session ran, counts of prompts and tool actions, a list of currently modified or untracked files, a summary of uncommitted changes, and details from your most recent commits. If there was a clear next step mentioned in the interrupted session, it tries to include that too. To use it, you need Python 3.10 or newer, Git, and either Claude Code or Codex CLI using their normal local session storage, no extra packages need installing. After downloading the single script file, you run it with a path to your repository, and it creates the passationlive.md file. You can then open the other agent in the same repository and branch and ask it to read that file, check the current Git status and diff, and continue the interrupted work without redoing what is already done. The tool is meant to be used in one direction at a time, not with both agents running against the same working tree simultaneously. There are limits to what it can recover: it cannot see text that was never saved to disk, hidden reasoning the model didn't write down, or intentions that were never captured anywhere. Since the output file can include excerpts from prompts, commands, and local source files, it is worth reviewing before sharing or committing it. The script makes no network requests. It is released under the MIT license.
