Can I use this with languages other than JavaScript?

Yes, the skill is framework-agnostic and supports any language with a command-line test runner, including Node.js (Jest) and Python (Pytest).

Do I need to set up the Git hooks manually?

No, the skill includes an /overnight-setup command and specialized setup scripts that automate the creation of the necessary Git hooks and configuration files.

How does the Overnight Development skill ensure code quality?

It uses Git hooks to block all commits until the code passes every unit and integration test, enforcing a strict TDD cycle and preventing broken code from entering the repository.

How do I monitor what Claude did while I was away?

The skill maintains a dedicated log file (.overnight-dev-log.txt) that records every test failure, fix attempt, and successful commit made during the session.

Productivity & Workflow

Automates software development through a rigorous, test-driven workflow powered by Git hooks to ensure production-ready code while you sleep.

About

Overnight Development is a specialized Claude Code skill designed for autonomous coding sessions that prioritize quality and stability. By leveraging Git hooks to enforce Test-Driven Development (TDD), it prevents invalid commits and forces Claude to iterate on code until all unit and integration tests pass. Whether building new features from scratch, refactoring complex legacy modules, or fixing persistent bugs, this skill provides a structured environment for Claude to work independently, maintaining a detailed activity log and providing a clean, fully-tested codebase upon completion.
