@dependabit/action

GitHub Action entry points for AI-powered dependency tracking.

Overview

This package provides the main entry points for the dependabit GitHub Actions, orchestrating all other packages to provide a complete dependency tracking solution using LLM-powered detection.

Features

• Generate action: Create initial manifest from codebase analysis
• Update action: Automatically update manifest on push
• Check action: Monitor dependencies for changes and create issues
• Validate action: Validate manifest files and configuration
• Authentication: Multiple auth methods (token, OAuth, basic)
• Secret Management: Secure resolution from GitHub Secrets
• Performance Tracking: Operation duration metrics and API quota monitoring
• Error Handling: Categorized errors with remediation steps
• Manifest Size Checks: Automatic warnings for large manifests

Installation

This package is distributed as part of the dependabit GitHub Action. See the main repository README for usage instructions.

Actions

Generate

Analyzes repository using LLM and generates .dependabit/manifest.json with detected dependencies.

Inputs:

• github-token: GitHub token for API access (required)
• llm-provider: LLM provider (default: copilot)
• config-path: Path to config file (default: .dependabit/config.yml)

Outputs:

• manifest-path: Path to generated manifest
• dependencies-count: Number of dependencies detected

Example:

- uses: ./.github/actions/dependabit
  with:
    action: generate
    github-token: ${{ secrets.GITHUB_TOKEN }}

Update

Automatically updates manifest when code changes are pushed.

Triggers:

• Push to main/master branch
• Pull request changes
• Manual workflow dispatch

Example:

on:
  push:
    branches: [main]

jobs:
  update-dependencies:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: ./.github/actions/dependabit
        with:
          action: update
          github-token: ${{ secrets.GITHUB_TOKEN }}

Check

Periodically checks dependencies for changes and creates issues for updates.

Schedule: Configurable in .dependabit/config.yml (default: daily)

Features:

• Release monitoring
• Breaking change detection
• Automatic issue creation
• False positive tracking

Example:

on:
  schedule:
    - cron: '0 0 * * *'  # Daily at midnight

jobs:
  check-dependencies:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: ./.github/actions/dependabit
        with:
          action: check
          github-token: ${{ secrets.GITHUB_TOKEN }}

Validate

Validates manifest file structure and content.

Checks:

• Schema validation
• Size limits
• Required fields
• Configuration syntax

Example:

- uses: ./.github/actions/dependabit
  with:
    action: validate
    manifest-path: .dependabit/manifest.json

Authentication

Supports multiple authentication methods:

Token Authentication (Recommended)

- uses: ./.github/actions/dependabit
  with:
    github-token: ${{ secrets.GITHUB_TOKEN }}

Per-Dependency Authentication

Configure in .dependabit/config.yml:

auth:
  registry.npmjs.org:
    secret: NPM_TOKEN
  api.example.com:
    secret: API_KEY

Configuration

Create .dependabit/config.yml:

version: "1.0"
schedule: "0 0 * * *"  # Daily checks
llm:
  provider: copilot
  model: gpt-4
monitor:
  check_interval: 24h
  severity_threshold: minor
issues:
  labels:
    - dependency-update
    - bot
  assignees:
    - maintainer-username

Performance Metrics

The action tracks performance metrics:

• Operation durations
• API quota usage
• Rate limit status
• Error rates

View metrics in action logs or enable detailed reporting:

- uses: ./.github/actions/dependabit
  with:
    action: check
    enable-metrics: true

Error Handling

Errors are categorized with remediation steps:

• Authentication: Token validation, permissions
• Rate Limit: API quota management
• Network: Connectivity issues
• Validation: Data format errors
• Configuration: Setup problems

Manifest Size Management

Automatic warnings for large manifests:

• Warning: >1MB
• Error: >10MB

Recommendations provided for size reduction.
