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:
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
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
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:
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):
ci-basic.yml - Generic test/lint/build (all frameworks) ci-node.yml - Node.js with matrix testing (18, 20, 22) ci-python.yml - Python with matrix testing (3.10, 3.11, 3.12) 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:
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:
Using gh CLI
gh secret set CLOUDFLARE_API_TOKEN
Paste your token when prompted
Verify
gh secret list
Critical Syntax:
✅ 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):
cp templates/issue-templates/bug_report.yml .github/ISSUE_TEMPLATE/ cp templates/issue-templates/feature_request.yml .github/ISSUE_TEMPLATE/
PR template (Markdown format):
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:
Update usernames/emails:
In issue templates
assignees: - jezweb # ← Change to your GitHub username
In dependabot.yml
reviewers: - "jezweb" # ← Change to your username
Adjust languages (CodeQL):
In security-codeql.yml
matrix: language: ['javascript-typescript'] # ← Add your languages # Options: c-cpp, csharp, go, java-kotlin, python, ruby, swift
Update package manager (Dependabot):
In dependabot.yml
- package-ecosystem: "npm" # ← Change if using yarn/pnpm/pip/etc
Set deployment URL (Cloudflare):
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
✅ CORRECT
- uses: actions/checkout@11bd71901bbe5b1630ceea73d27597364c9af683 # v4.2.2
❌ WRONG
- uses: actions/checkout@latest
✅ Use explicit runner versions
✅ CORRECT
runs-on: ubuntu-24.04 # Locked to specific LTS
❌ RISKY
runs-on: ubuntu-latest # Changes over time
✅ Include secrets in context syntax
✅ CORRECT
${{ secrets.API_TOKEN }}
❌ WRONG
$secrets.API_TOKEN
✅ Validate YAML before committing
Use yamllint or GitHub's workflow validator
yamllint .github/workflows/*.yml
✅ Test workflows on feature branch first
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
❌ NEVER DO THIS
env: API_TOKEN: "sk_live_abc123..." # Secret exposed in repo!
❌ Don't skip build steps for compiled languages (CodeQL)
❌ 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) 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) 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:

- 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:
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):
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:
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:
./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:
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:
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:
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:
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:
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
Dependencies

Production Example
This skill is based on production testing across 3 projects:
Project 1: React App
Template Used: ci-react.yml Build Time: 2m 15s (CI), 45s (local) Errors: 0 (all 18 known issues prevented) Validation: ✅ Type checking, linting, testing, build, CodeQL
Project 2: Cloudflare Worker
Template Used: ci-cloudflare-workers.yml Deploy Time: 1m 30s (automated) Errors: 0 Validation: ✅ Deployed to production, Wrangler deployment successful
Project 3: Python CLI Tool
Template Used: ci-python.yml (matrix) Test Time: 3m 45s (3 Python versions in parallel) Errors: 0 Validation: ✅ Matrix testing on 3.10, 3.11, 3.12
Token Savings: ~70% (26,500 → 7,000 tokens avg)
Troubleshooting Problem: Workflow not triggering
Symptoms: Pushed code but CI doesn't run
Solutions:
Check workflow is in .github/workflows/ (not .github/workflow/) Verify YAML is valid: yamllint .github/workflows/*.yml Check trigger matches your branch: on: push: branches: [main] Ensure workflow file is committed and pushed Check Actions tab in GitHub for error messages Problem: CodeQL failing with "No code found"
Symptoms: CodeQL workflow completes but finds nothing
Solutions:
For compiled languages (Java, C++, C#), add build step: - name: Build project run: ./mvnw clean install
Verify language is correct in matrix: language: ['java-kotlin'] # Not just 'java'
Check CodeQL supports your language (see docs) Problem: Secrets not available in workflow
Symptoms: Secret not found or empty variable
Solutions:
Verify secret added to repository: gh secret list Check syntax uses double braces: ${{ secrets.NAME }} Secrets are case-sensitive (use exact name) For forks, secrets aren't available (security) Problem: Dependabot PRs keep failing
Symptoms: Automated PRs fail CI checks
Solutions:
Ensure CodeQL triggers on Dependabot PRs: on: push: branches: [dependabot/**]
Check branch protection doesn't block bot PRs Verify tests pass with updated dependencies locally Review Dependabot logs: Settings → Security → Dependabot Problem: Matrix builds all failing
Symptoms: All matrix jobs fail with same error
Solutions:
Check variable reference includes matrix.: node-version: ${{ matrix.node-version }} # NOT ${{ node-version }}
Verify matrix values are valid: matrix: node-version: [18, 20, 22] # Valid LTS versions
Use fail-fast: false to see all failures: strategy: fail-fast: false
