Which programming languages and frameworks are supported?

It is language-agnostic and supports any framework triggered via CLI, including Jest for Node.js, pytest for Python, and others through customizable test commands.

What happens if Claude encounters a persistent error?

All activities are recorded in a .overnight-dev-log.txt file, allowing you to review Claude's debugging attempts, the blocked commits, and the final state of the code in the morning.

Do I need to configure Git hooks manually?

No, the skill provides an /overnight-setup command that automatically configures the necessary Git hooks and configuration files for your repository.

How does the skill ensure code quality during autonomous sessions?

The skill utilizes Git hooks to block any commits that fail unit tests or linting checks, requiring Claude to analyze errors and fix the code until it passes all requirements.

Productivity & Workflow

Automates end-to-end software development sessions using Git hooks to enforce rigorous test-driven development (TDD) workflows.

About

The Overnight Development skill enables Claude to work autonomously on complex coding tasks by leveraging a strict TDD workflow enforced via Git hooks. By blocking commits until all tests and linting requirements pass, it ensures that features, refactors, and bug fixes meet production-quality standards without constant human supervision. It is an ideal solution for developers who want to assign high-level goals—such as implementing authentication systems or refactoring legacy modules—and return to fully tested, documented, and committed code.

Key Features

Automated TDD enforcement via Git pre-commit hooks
Autonomous debugging and iterative code fixing until tests pass
Multi-framework support for languages like JavaScript and Python
Detailed progress tracking through dedicated activity logs
Integrated overnight-dev-coach for guided implementation
884 GitHub stars

Use Cases

Performing large-scale codebase refactoring while ensuring zero regressions
Building complex new features with high test coverage while the developer is away
Fixing critical bugs by automatically reproducing them with tests and iterating on solutions
