# GitHub Project Automation

**Status**: Production Ready ✅
**Last Updated**: 2025-11-06
**Dependencies**: None (git and gh CLI recommended)
**Latest Versions**: actions/checkout@v4.2.2, actions/setup-node@v4.1.0, github/codeql-action@v3.27.4

---

## Quick Start (15 Minutes)

### 1. Choose Your Framework

Select the workflow template that matches your project:

```bash
# For React/Vite projects
cp templates/workflows/ci-react.yml .github/workflows/ci.yml

# For Node.js libraries (matrix testing)
cp templates/workflows/ci-node.yml .github/workflows/ci.yml

# For Python projects
cp templates/workflows/ci-python.yml .github/workflows/ci.yml

# For Cloudflare Workers
cp templates/workflows/ci-cloudflare-workers.yml .github/workflows/deploy.yml

# For basic projects (any framework)
cp templates/workflows/ci-basic.yml .github/workflows/ci.yml
```

**Why this matters:**
- Pre-validated YAML prevents syntax errors
- SHA-pinned actions for security
- Explicit runner versions (ubuntu-24.04)
- All 8 GitHub Actions errors prevented

### 2. Add Issue Templates

```bash
# Create directory structure
mkdir -p .github/ISSUE_TEMPLATE

# Copy YAML templates (with validation)
cp templates/issue-templates/bug_report.yml .github/ISSUE_TEMPLATE/
cp templates/issue-templates/feature_request.yml .github/ISSUE_TEMPLATE/
```

**Why YAML over Markdown:**
- Required field validation (Error #12 prevented)
- Consistent data structure
- Better user experience
- No incomplete issues

### 3. Enable Security Scanning

```bash
# CodeQL for code analysis
cp templates/workflows/security-codeql.yml .github/workflows/codeql.yml

# Dependabot for dependency updates
cp templates/security/dependabot.yml .github/dependabot.yml
```

**CRITICAL:**
- CodeQL requires specific permissions (security-events: write)
- Dependabot has 10 PR limit per ecosystem
- Both must run on Dependabot PRs (Error #13 prevention)

---

## The 5-Step Complete Setup Process

### Step 1: Repository Structure

Create the standard GitHub automation directory structure:

```bash
# Create all required directories
mkdir -p .github/{workflows,ISSUE_TEMPLATE}

# Verify structure
tree .github/
# .github/
# ├── workflows/        # GitHub Actions workflows
# ├── ISSUE_TEMPLATE/   # Issue templates
# └── dependabot.yml    # Dependabot config (root of .github/)
```

**Key Points:**
- workflows/ is plural
- ISSUE_TEMPLATE/ is singular (legacy naming)
- dependabot.yml goes in .github/, NOT workflows/

### Step 2: Select Workflow Templates

Choose workflows based on your project needs:

**Continuous Integration (pick ONE):**
1. `ci-basic.yml` - Generic test/lint/build (all frameworks)
2. `ci-node.yml` - Node.js with matrix testing (18, 20, 22)
3. `ci-python.yml` - Python with matrix testing (3.10, 3.11, 3.12)
4. `ci-react.yml` - React/TypeScript with type checking

**Deployment (optional):**
5. `ci-cloudflare-workers.yml` - Deploy to Cloudflare Workers

**Security (recommended):**
6. `security-codeql.yml` - Code scanning
7. `dependabot.yml` - Dependency updates

**Copy selected templates:**
```bash
# Example: React app with security
cp templates/workflows/ci-react.yml .github/workflows/ci.yml
cp templates/workflows/security-codeql.yml .github/workflows/codeql.yml
cp templates/security/dependabot.yml .github/dependabot.yml
```

### Step 3: Configure Secrets (if deploying)

For deployment workflows (Cloudflare, AWS, etc.), add secrets:

```bash
# Using gh CLI
gh secret set CLOUDFLARE_API_TOKEN
# Paste your token when prompted

# Verify
gh secret list
```

**Critical Syntax:**
```yaml
# ✅ CORRECT
env:
  API_TOKEN: ${{ secrets.CLOUDFLARE_API_TOKEN }}

# ❌ WRONG - Missing double braces
env:
  API_TOKEN: $secrets.CLOUDFLARE_API_TOKEN
```

Prevents Error #6 (secrets syntax).

### Step 4: Add Issue/PR Templates

**Issue templates (YAML format):**
```bash
cp templates/issue-templates/bug_report.yml .github/ISSUE_TEMPLATE/
cp templates/issue-templates/feature_request.yml .github/ISSUE_TEMPLATE/
```

**PR template (Markdown format):**
```bash
cp templates/pr-templates/PULL_REQUEST_TEMPLATE.md .github/
```

**Why separate formats:**
- Issue templates: YAML for validation
- PR template: Markdown (GitHub limitation)

### Step 5: Customize for Your Project

**Required customizations:**

1. **Update usernames/emails:**
   ```yaml
   # In issue templates
   assignees:
     - jezweb  # ← Change to your GitHub username
   
   # In dependabot.yml
   reviewers:
     - "jezweb"  # ← Change to your username
   ```

2. **Adjust languages (CodeQL):**
   ```yaml
   # In security-codeql.yml
   matrix:
     language: ['javascript-typescript']  # ← Add your languages
     # Options: c-cpp, csharp, go, java-kotlin, python, ruby, swift
   ```

3. **Update package manager (Dependabot):**
   ```yaml
   # In dependabot.yml
   - package-ecosystem: "npm"  # ← Change if using yarn/pnpm/pip/etc
   ```

4. **Set deployment URL (Cloudflare):**
   ```yaml
   # In ci-cloudflare-workers.yml
   echo "Worker URL: https://your-worker.your-subdomain.workers.dev"
   # ← Update with your actual Worker URL
   ```

---

## Critical Rules

### Always Do

✅ **Pin actions to SHA, not @latest**
```yaml
# ✅ CORRECT
- uses: actions/checkout@11bd71901bbe5b1630ceea73d27597364c9af683  # v4.2.2

# ❌ WRONG
- uses: actions/checkout@latest
```

✅ **Use explicit runner versions**
```yaml
# ✅ CORRECT
runs-on: ubuntu-24.04  # Locked to specific LTS

# ❌ RISKY
runs-on: ubuntu-latest  # Changes over time
```

✅ **Include secrets in context syntax**
```yaml
# ✅ CORRECT
${{ secrets.API_TOKEN }}

# ❌ WRONG
$secrets.API_TOKEN
```

✅ **Validate YAML before committing**
```bash
# Use yamllint or GitHub's workflow validator
yamllint .github/workflows/*.yml
```

✅ **Test workflows on feature branch first**
```bash
git checkout -b test/github-actions
# Push and verify CI runs before merging to main
```

### Never Do

❌ **Don't use @latest for action versions**
- Breaks without warning when actions update
- Security risk (unvetted versions auto-adopted)

❌ **Don't hardcode secrets in workflows**
```yaml
# ❌ NEVER DO THIS
env:
  API_TOKEN: "sk_live_abc123..."  # Secret exposed in repo!
```

❌ **Don't skip build steps for compiled languages (CodeQL)**
```yaml
# ❌ WRONG - CodeQL fails for Java without build
- name: Perform CodeQL Analysis  # No .class files to analyze

# ✅ CORRECT - Include build
- name: Build project
  run: ./mvnw clean install
- name: Perform CodeQL Analysis  # Now has .class files
```

❌ **Don't ignore devDependencies in Dependabot**
- DevDependencies run during build, can execute malicious code
- Include both prod and dev dependencies

❌ **Don't use single ISSUE_TEMPLATE.md file**
```
# ❌ OLD WAY
.github/ISSUE_TEMPLATE.md

# ✅ NEW WAY
.github/ISSUE_TEMPLATE/
  bug_report.yml
  feature_request.yml
```

## Known Issues Prevention

This skill prevents **18** documented issues:

### Issue #1: YAML Indentation Errors
**Error**: `workflow file is invalid. mapping values are not allowed in this context`
**Source**: Stack Overflow (most common GitHub Actions error)
**Why It Happens**: Spaces vs tabs, missing spaces after colons, inconsistent indentation
**Prevention**: Use skill templates with validated 2-space indentation

### Issue #2: Missing `run` or `uses` Field
**Error**: `Error: Step must have a run or uses key`
**Source**: GitHub Actions Error Logs
**Why It Happens**: Empty step definition, forgetting to add command
**Prevention**: Templates include complete step definitions

### Issue #3: Action Version Pinning Issues
**Error**: Workflow breaks unexpectedly after action updates
**Source**: GitHub Security Best Practices 2025
**Why It Happens**: Using `@latest` or `@v4` instead of specific SHA
**Prevention**: All templates pin to SHA with version comment

### Issue #4: Incorrect Runner Version
**Error**: Unexpected environment changes, compatibility issues
**Source**: CI/CD Troubleshooting Guides
**Why It Happens**: `ubuntu-latest` changed from 22.04 → 24.04 in 2024
**Prevention**: Templates use explicit `ubuntu-24.04`

### Issue #5: Multiple Keys with Same Name
**Error**: `duplicate key found in mapping`
**Source**: YAML Parser Updates
**Why It Happens**: Copy-paste errors, duplicate job/step names
**Prevention**: Templates use unique, descriptive naming

### Issue #6: Secrets Not Available
**Error**: `Secret not found` or empty variable
**Source**: GitHub Actions Debugging Guides
**Why It Happens**: Wrong syntax (`$secrets.NAME` instead of `${{ secrets.NAME }}`)
**Prevention**: Templates demonstrate correct context syntax

### Issue #7: Matrix Strategy Errors
**Error**: Matrix doesn't expand, tests skipped
**Source**: Troubleshooting Guides
**Why It Happens**: Invalid matrix config, wrong variable reference
**Prevention**: Templates include working matrix examples

### Issue #8: Context Syntax Errors
**Error**: Variables not interpolated, empty values
**Source**: GitHub Actions Docs
**Why It Happens**: Forgetting `${{ }}` wrapper
**Prevention**: Templates show all context patterns

### Issue #9: Overly Complex Templates
**Error**: Contributors ignore template, incomplete issues
**Source**: GitHub Best Practices
**Why It Happens**: 20+ fields, asking irrelevant details
**Prevention**: Skill templates are minimal (5-8 fields max)

### Issue #10: Generic Prompts Without Context
**Error**: Vague bug reports, hard to reproduce
**Source**: Template Best Practices
**Why It Happens**: No guidance on what info is needed
**Prevention**: Templates include specific placeholders

### Issue #11: Multiple Template Confusion
**Error**: Users don't know which template to use
**Source**: GitHub Docs
**Why It Happens**: Using single `ISSUE_TEMPLATE.md` file
**Prevention**: Proper `ISSUE_TEMPLATE/` directory with config.yml

### Issue #12: Missing Required Fields
**Error**: Incomplete issues, missing critical info
**Source**: Community Feedback
**Why It Happens**: Markdown templates don't validate
**Prevention**: YAML templates with `required: true`

### Issue #13: CodeQL Not Running on Dependabot PRs
**Error**: Security scans skipped on dependency updates
**Source**: GitHub Community Discussion #121836
**Why It Happens**: Default trigger limitations
**Prevention**: Templates include `push: branches: [dependabot/**]`

### Issue #14: Branch Protection Blocking All PRs
**Error**: Legitimate PRs blocked, development stalled
**Source**: Security Alerts Guide
**Why It Happens**: Over-restrictive alert policies
**Prevention**: Reference docs explain proper scoping

### Issue #15: Compiled Language CodeQL Setup
**Error**: `No code found to analyze`
**Source**: CodeQL Documentation
**Why It Happens**: Missing build steps for Java/C++/C#
**Prevention**: Templates include build examples

### Issue #16: Development Dependencies Ignored
**Error**: Vulnerable devDependencies not scanned
**Source**: Security Best Practices
**Why It Happens**: Thinking devDependencies don't matter
**Prevention**: Templates scan all dependencies

### Issue #17: Dependabot Alert Limit
**Error**: Only 10 alerts auto-fixed, others queued
**Source**: GitHub Docs (hard limit)
**Why It Happens**: GitHub limits 10 open PRs per ecosystem
**Prevention**: Templates document limit and workaround

### Issue #18: Workflow Duplication
**Error**: Wasted CI minutes, maintenance overhead
**Source**: DevSecOps Guides
**Why It Happens**: Separate workflows for CI/CodeQL/dependency review
**Prevention**: Templates offer integrated option

**See**: `references/common-errors.md` for detailed error documentation with examples

## Configuration Files Reference

### dependabot.yml (Full Example)

```yaml
version: 2
updates:
  # npm dependencies (including devDependencies)
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
      day: "monday"
      time: "09:00"
      timezone: "Australia/Sydney"
    open-pull-requests-limit: 10  # GitHub hard limit
    reviewers:
      - "jezweb"
    labels:
      - "dependencies"
      - "npm"
    commit-message:
      prefix: "chore"
      prefix-development: "chore"
      include: "scope"

  # GitHub Actions
  - package-ecosystem: "github-actions"
    directory: "/"
    schedule:
      interval: "weekly"
    open-pull-requests-limit: 5
    labels:
      - "dependencies"
      - "github-actions"
```

**Why these settings:**
- Weekly schedule reduces noise vs daily
- 10 PR limit matches GitHub maximum
- Includes devDependencies (Error #16 prevention)
- Reviewers auto-assigned for faster triage
- Conventional commit prefixes (chore: for deps)

### CodeQL Workflow (security-codeql.yml)

```yaml
name: CodeQL Security Scan

on:
  push:
    branches: [main, master]
  pull_request:
    branches: [main, master]
  schedule:
    - cron: '0 0 * * 0'  # Weekly on Sundays

jobs:
  analyze:
    runs-on: ubuntu-24.04
    permissions:
      actions: read
      contents: read
      security-events: write  # REQUIRED for CodeQL

    strategy:
      fail-fast: false
      matrix:
        language: ['javascript-typescript']  # Add your languages

    steps:
      - uses: actions/checkout@11bd71901bbe5b1630ceea73d27597364c9af683

      - name: Initialize CodeQL
        uses: github/codeql-action/init@ea9e4e37992a54ee68a9622e985e60c8e8f12d9f
        with:
          languages: ${{ matrix.language }}

      # For compiled languages, add build here

      - name: Perform CodeQL Analysis
        uses: github/codeql-action/analyze@ea9e4e37992a54ee68a9622e985e60c8e8f12d9f
```

**Critical permissions:**
- `security-events: write` is REQUIRED for CodeQL uploads
- Without it, workflow fails silently

---

## Common Patterns

### Pattern 1: Multi-Framework Matrix Testing

Use for libraries that support multiple Node.js/Python versions:

```yaml
strategy:
  matrix:
    node-version: [18, 20, 22]  # LTS versions
  fail-fast: false  # Test all versions even if one fails

steps:
  - uses: actions/setup-node@39370e3970a6d050c480ffad4ff0ed4d3fdee5af
    with:
      node-version: ${{ matrix.node-version }}
      cache: 'npm'  # Cache dependencies for speed

  - run: npm ci  # Use ci (not install) for reproducible builds
  - run: npm test
```

**When to use**: Libraries, CLI tools, packages with broad version support

### Pattern 2: Conditional Deployment

Deploy only on push to main (not PRs):

```yaml
jobs:
  deploy:
    if: github.event_name == 'push' && github.ref == 'refs/heads/main'
    steps:
      - run: npx wrangler deploy
        env:
          CLOUDFLARE_API_TOKEN: ${{ secrets.CLOUDFLARE_API_TOKEN }}
```

**When to use**: Production deployments, avoiding test deployments from PRs

### Pattern 3: Artifact Upload/Download

Share build outputs between jobs:

```yaml
jobs:
  build:
    steps:
      - run: npm run build
      - uses: actions/upload-artifact@b4b15b8c7c6ac21ea08fcf65892d2ee8f75cf882
        with:
          name: build-output
          path: dist/
          retention-days: 7

  deploy:
    needs: build
    steps:
      - uses: actions/download-artifact@fa0a91b85d4f404e444e00e005971372dc801d16
        with:
          name: build-output
          path: dist/
      - run: # Deploy from dist/
```

**When to use**: Separating build and deployment, sharing test results

---

## Using Bundled Resources

### Scripts (scripts/)

**Coming in Phase 3** - Automation scripts for common tasks:

- `setup-github-project.sh` - Interactive setup wizard
- `validate-workflows.sh` - YAML validation before commit
- `generate-codeowners.sh` - Auto-generate from git log
- `sync-templates.sh` - Update existing projects

**Example Usage:**
```bash
./scripts/setup-github-project.sh react
# Prompts for project details, generates .github/ structure
```

### References (references/)

**Load when needed** for detailed error resolution:

- `references/common-errors.md` - All 18 errors with solutions (complete)
- `references/github-actions-reference.md` - Complete Actions API (Phase 2)
- `references/workflow-syntax.md` - YAML syntax guide (Phase 2)
- `references/dependabot-guide.md` - Dependabot deep-dive (Phase 2)
- `references/codeql-guide.md` - CodeQL configuration (Phase 2)
- `references/secrets-management.md` - Secrets best practices (Phase 2)
- `references/matrix-strategies.md` - Matrix patterns (Phase 2)

**When Claude should load these**: When user encounters specific errors, needs deep configuration, or troubleshooting complex scenarios

### Templates (templates/)

**Complete collection** - 45+ files organized by type:

**Workflows (12 templates):**
- Phase 1 (complete): ci-basic, ci-node, ci-python, ci-react, ci-cloudflare-workers, security-codeql
- Phase 2: ci-matrix, cd-production, release, pr-checks, scheduled-maintenance, security-dependency-review

**Issue Templates (4 templates):**
- Phase 1 (complete): bug_report.yml, feature_request.yml
- Phase 2: documentation.yml, config.yml

**PR Templates (3 templates):**
- Phase 1 (complete): PULL_REQUEST_TEMPLATE.md
- Phase 2: feature.md, bugfix.md

**Security (3 templates):**
- Phase 1 (complete): dependabot.yml
- Phase 2: SECURITY.md, codeql-config.yml

**Misc (2 templates):**
- Phase 2: CODEOWNERS, FUNDING.yml

## Integration with Existing Skills

### cloudflare-worker-base → Add CI/CD

When user creates new Worker project:

```bash
# User: "Create Cloudflare Worker with CI/CD"

# This skill runs AFTER cloudflare-worker-base
cp templates/workflows/ci-cloudflare-workers.yml .github/workflows/deploy.yml

# Configure secrets
gh secret set CLOUDFLARE_API_TOKEN
```

**Result**: New Worker with automated deployment on push to main

### project-planning → Generate Automation

When user uses project-planning skill:

```bash
# User: "Plan new React app with GitHub automation"

# project-planning generates IMPLEMENTATION_PHASES.md
# Then this skill sets up GitHub automation
cp templates/workflows/ci-react.yml .github/workflows/ci.yml
cp templates/issue-templates/*.yml .github/ISSUE_TEMPLATE/
```

**Result**: Planned project with complete GitHub automation

### open-source-contributions → Setup Contributor Experience

When preparing project for open source:

```bash
# User: "Prepare repo for open source contributions"

# open-source-contributions skill handles CONTRIBUTING.md
# This skill adds issue templates and CODEOWNERS
cp templates/issue-templates/*.yml .github/ISSUE_TEMPLATE/
cp templates/misc/CODEOWNERS .github/
```

**Result**: Contributor-friendly repository

---

## Advanced Topics

### Integrating with GitHub Projects v2

**Status**: Researched, not implemented (see `/planning/github-projects-poc-findings.md`)

**Why separate skill**: Complex GraphQL API, ID management, niche use case

**When to consider**: Team projects needing automated board management

### Custom Workflow Composition

**Combining workflows for efficiency**:

```yaml
# Option A: Separate workflows (easier maintenance)
.github/workflows/
  ci.yml         # Test and build
  codeql.yml     # Security scanning
  deploy.yml     # Production deployment

# Option B: Integrated workflow (fewer CI minutes)
.github/workflows/
  main.yml       # All-in-one: test, scan, deploy
```

**Trade-off**: Separate = clearer, Integrated = faster (Error #18 prevention)

### Multi-Environment Deployments

**Deploy to staging and production**:

```yaml
jobs:
  deploy-staging:
    if: github.ref == 'refs/heads/develop'
    steps:
      - run: npx wrangler deploy --env staging

  deploy-production:
    if: github.ref == 'refs/heads/main'
    steps:
      - run: npx wrangler deploy --env production
```

**Requires**: Wrangler environments configured in `wrangler.jsonc`

## Troubleshooting

### Problem: Workflow not triggering

**Symptoms**: Pushed code but CI doesn't run

**Solutions**:
1. Check workflow is in `.github/workflows/` (not `.github/workflow/`)
2. Verify YAML is valid: `yamllint .github/workflows/*.yml`
3. Check trigger matches your branch: `on: push: branches: [main]`
4. Ensure workflow file is committed and pushed
5. Check Actions tab in GitHub for error messages

### Problem: CodeQL failing with "No code found"

**Symptoms**: CodeQL workflow completes but finds nothing

**Solutions**:
1. For compiled languages (Java, C++, C#), add build step:
   ```yaml
   - name: Build project
     run: ./mvnw clean install
   ```
2. Verify language is correct in matrix:
   ```yaml
   language: ['java-kotlin']  # Not just 'java'
   ```
3. Check CodeQL supports your language (see docs)

### Problem: Secrets not available in workflow

**Symptoms**: `Secret not found` or empty variable

**Solutions**:
1. Verify secret added to repository: `gh secret list`
2. Check syntax uses double braces: `${{ secrets.NAME }}`
3. Secrets are case-sensitive (use exact name)
4. For forks, secrets aren't available (security)

### Problem: Dependabot PRs keep failing

**Symptoms**: Automated PRs fail CI checks

**Solutions**:
1. Ensure CodeQL triggers on Dependabot PRs:
   ```yaml
   on:
     push:
       branches: [dependabot/**]
   ```
2. Check branch protection doesn't block bot PRs
3. Verify tests pass with updated dependencies locally
4. Review Dependabot logs: Settings → Security → Dependabot

### Problem: Matrix builds all failing

**Symptoms**: All matrix jobs fail with same error

**Solutions**:
1. Check variable reference includes `matrix.`:
   ```yaml
   node-version: ${{ matrix.node-version }}  # NOT ${{ node-version }}
   ```
2. Verify matrix values are valid:
   ```yaml
   matrix:
     node-version: [18, 20, 22]  # Valid LTS versions
   ```
3. Use `fail-fast: false` to see all failures:
   ```yaml
   strategy:
     fail-fast: false
   ```

## Complete Setup Checklist

Use this checklist to verify your GitHub automation setup:

**Workflows:**
- [ ] Created `.github/workflows/` directory
- [ ] Copied appropriate CI workflow template
- [ ] Updated usernames in workflow files
