# Dependabot: Automated Dependency Updates
[Dependabot](https://docs.github.com/en/code-security/dependabot) automatically creates pull requests to keep your dependencies up to date. GitHub hosts it natively—no external service required.

## Overview

# Dependabot: Automated Dependency Updates

[Dependabot](https://docs.github.com/en/code-security/dependabot) automatically creates pull requests to keep your dependencies up to date. GitHub hosts it natively—no external service required.

## Why Use Dependabot?

- **Security**: Automatically patches known vulnerabilities
- **Freshness**: Keeps dependencies current without manual tracking
- **Visibility**: PRs show changelogs and compatibility notes

## Configuration

Copy [templates/dependabot.yml](../templates/dependabot.yml) to `.github/dependabot.yml`.

The template includes:
- Weekly update schedule for pip and GitHub Actions
- 7-day cooldown for supply chain protection
- Grouping to reduce PR noise

## Supply Chain Protection

The `cooldown.default-days: 7` setting delays updates for newly published versions. This provides time for the community to detect compromised packages before they reach your project.

**Why this matters:**
- Attackers sometimes publish malicious versions of legitimate packages
- A 7-day delay allows time for detection and removal
- Combined with weekly schedules, this balances security with freshness

## Common Options

| Option | Description |
|--------|-------------|
| `interval` | `daily`, `weekly`, or `monthly` |
| `cooldown.default-days` | Days to wait before updating new releases |
| `ignore` | Skip specific dependencies or versions |
| `groups` | Group related updates into single PRs |
| `reviewers` | Auto-assign reviewers to PRs |
