vexy-overnight

vexy-overnight starts AI coding assistants (Claude Code, Codex and Gemini CLI) with fixed flags, and can hand a session that has just finished over to the next assistant, so that work continues without you typing the next command. It also keeps the instruction files those tools read (CLAUDE.md, AGENTS.md, GEMINI.md and others) identical across a project.

The package installs five commands:

Command	Purpose
vomgr	Install the continuation hooks, switch them on and off, set preferences, sync instruction files, update the CLIs
vocl	Start Claude Code
voco	Start Codex
voge	Start Gemini CLI
version-bump	Tag the next patch version in a git repository and push it

How continuation works, in one example

You have run vomgr install and vomgr enable claude. You start Claude in a project:

cd ~/work/my-app
vocl

When Claude finishes its turn and stops:

1. Claude runs its Stop hook, which vomgr enable claude pointed at ~/.claude/hooks/vocl-go.py.
2. vocl-go.py reads your preferences from ~/.vexy-overnight/settings.toml. By default, Claude hands over to Codex.
3. It builds a prompt from the template for Claude, filling in up to five open - [ ] items from ~/work/my-app/TODO.md.
4. It writes the Codex command line, the project directory and some environment variables to ~/.claude/hooks/vocl-new.json.
5. It runs the terminal command configured for your platform (on macOS, by default, open -a Terminal …) and passes it a shell command that runs the helper vocl-new.py.
6. The helper reads the JSON file, starts Codex in ~/work/my-app with the prompt and records the new process in ~/.vexy-overnight/session_state.json. If psutil is installed, it also stops the assistant process recorded there before.

Codex's notify hook works the same way and, by default, hands back to Claude.

The details are in How continuation works.

The assistants run without confirmations

vocl, voco, voge and the continuation commands start the assistants with their permission and sandbox checks turned off (--dangerously-skip-permissions, --dangerously-bypass-approvals-and-sandbox --sandbox danger-full-access, -y). The assistant can then run any command and change any file without asking. Use them only in projects and on machines where that is acceptable.
