Overnight Setup

Overnight Development Setup

Install Git hooks and configure overnight autonomous development in your project.

What This Does

This command sets up your repository for overnight autonomous development sessions:

1. Installs Git Hooks - pre-commit and commit-msg hooks
2. Creates Config - .overnight-dev.json configuration file
3. Verifies Setup - Tests that hooks work correctly

Installation Steps

1. Check Prerequisites

First, verify you have:

• Git repository initialized (git status works)
• Test framework configured (Jest, pytest, etc.)
• At least 1 passing test
• Linter set up (ESLint, flake8, etc.)

2. Install the Hooks

The plugin will copy Git hooks to .git/hooks/:

• pre-commit - Runs linting and tests before each commit
• commit-msg - Enforces conventional commit format

3. Configure Your Project

Create .overnight-dev.json in your project root:

{
  "testCommand": "npm test",
  "lintCommand": "npm run lint",
  "requireCoverage": true,
  "minCoverage": 80,
  "autoFix": true,
  "maxAttempts": 50,
  "stopOnMorning": true,
  "morningHour": 7
}

Configuration Options:

• testCommand - Command to run tests (e.g., "pytest", "cargo test")
• lintCommand - Command to run linter
• requireCoverage - Enforce minimum test coverage
• minCoverage - Minimum coverage percentage (default: 80)
• autoFix - Automatically fix linting issues
• maxAttempts - Maximum commit attempts before alerting
• stopOnMorning - Stop work at a specific hour
• morningHour - Hour to stop (0-23)

4. Test the Setup

Verify the hooks work:

# Should run tests and linting
git commit --allow-empty -m "test: verify overnight dev hooks"

If hooks work correctly, you'll see:

 Overnight Dev: Running pre-commit checks...
 Running linting...
 Linting passed
 Running tests...
 All tests passed
 All checks passed! Proceeding with commit...

Project-Specific Examples

Node.js / JavaScript

{
  "testCommand": "npm test -- --coverage",
  "lintCommand": "npm run lint",
  "autoFix": true
}

Python

{
  "testCommand": "pytest --cov=. --cov-report=term-missing",
  "lintCommand": "flake8 . && black --check .",
  "autoFix": false
}

Rust

{
  "testCommand": "cargo test",
  "lintCommand": "cargo clippy -- -D warnings",
  "autoFix": false
}

Go

{
  "testCommand": "go test ./...",
  "lintCommand": "golangci-lint run",
  "autoFix": false
}

Starting an Overnight Session

Once setup is complete:

1. Define your goal:

   Task: Implement user authentication with JWT
   Success: All tests pass, coverage > 85%
   

2. Start coding:

   • Write tests first (TDD)
   • Implement features
   • Commit frequently
   • Let the hooks keep you honest

3. Claude works overnight:

   • Every commit must pass tests
   • Hooks enforce quality
   • Morning brings fully tested features

Troubleshooting

"Hooks not executing"

# Make hooks executable
chmod +x .git/hooks/pre-commit
chmod +x .git/hooks/commit-msg

"Tests failing immediately"

Make sure you have at least 1 passing test before starting:

npm test  # or pytest, cargo test, etc.

"Linting errors blocking commits"

Enable auto-fix in config:

{
  "autoFix": true
}

Or fix manually:

npm run lint -- --fix

What Happens During Overnight Sessions

1. You write code → Claude writes tests and implementation
2. You try to commit → Hooks run tests automatically
3. Tests fail → Claude debugs and fixes
4. Tests pass → Commit succeeds
5. Repeat → Until feature is complete
6. Morning → Wake up to fully tested code

Success Metrics

Track your overnight session:

• All commits have passing tests
• Coverage maintained or improved
• No linting errors
• Clean conventional commit messages
• Features fully implemented and documented

Pro Tips

1. Start with clear goals - Specific, testable objectives
2. Have existing tests - At least 1 passing test before starting
3. Use TDD - Write tests first, then implementation
4. Commit frequently - Small, passing commits
5. Trust the process - Hooks enforce quality automatically

Ready to start? Just begin coding and let the hooks guide you to fully tested features!
