+
+# Setup GitHub Actions for Claude Code
+
+Help the user set up showcase Claude Code GitHub Actions workflows in their repository.
+
+## Available Workflows
+
+| Workflow | Stack | Description |
+|----------|-------|-------------|
+| **PR Review** | Any | Automatically review pull requests with Claude |
+| **Documentation Sync** | Any | Keep docs in sync with code changes |
+| **Node.js Code Quality** | Node.js | Periodic code quality audits (requires npm) |
+| **Node.js Dependency Audit** | Node.js | Check for outdated/vulnerable dependencies (requires npm) |
+
+## Your Tasks
+
+1. **Ask which workflows to set up:**
+   Use AskUserQuestion to ask which workflows they want:
+   - PR Review (recommended for all projects, works with any language)
+   - Documentation Sync (works with any language)
+   - Node.js Code Quality (Node.js projects only)
+   - Node.js Dependency Audit (Node.js projects only)
+
+2. **Check prerequisites:**
+   - Verify `.github/workflows/` directory exists (create if needed)
+   - Check if ANTHROPIC_API_KEY secret reminder is needed
+
+3. **For each selected workflow, create the caller workflow:**
+
+### PR Review Workflow
+```yaml
+name: Claude PR Review
+
+on:
+  pull_request:
+  issue_comment:
+    types: [created]
+
+permissions:
+  contents: read
+  pull-requests: write
+  issues: read
+
+jobs:
+  review:
+    uses: aviadr1/claude-code-showcase/.github/workflows/showcase-pr-review.yml@main
+    secrets:
+      ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+### Documentation Sync Workflow
+```yaml
+name: Monthly Documentation Sync
+
+on:
+  schedule:
+    - cron: '0 9 1 * *'
+  workflow_dispatch:
+
+permissions:
+  contents: write
+  pull-requests: write
+
+jobs:
+  sync:
+    uses: aviadr1/claude-code-showcase/.github/workflows/showcase-docs-sync.yml@main
+    secrets:
+      ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+### Code Quality Workflow
+```yaml
+name: Weekly Code Quality Review
+
+on:
+  schedule:
+    - cron: '0 8 * * 0'
+  workflow_dispatch:
+
+permissions:
+  contents: write
+  pull-requests: write
+
+jobs:
+  quality:
+    uses: aviadr1/claude-code-showcase/.github/workflows/showcase-nodejs-code-quality.yml@main
+    secrets:
+      ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+### Dependency Audit Workflow
+```yaml
+name: Bi-weekly Dependency Audit
+
+on:
+  schedule:
+    - cron: '0 10 1,15 * *'
+  workflow_dispatch:
+
+permissions:
+  contents: write
+  pull-requests: write
+
+jobs:
+  audit:
+    uses: aviadr1/claude-code-showcase/.github/workflows/showcase-nodejs-dependency-audit.yml@main
+    secrets:
+      ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+4. **Remind about secrets:**
+   Tell the user to add `ANTHROPIC_API_KEY` to their repository secrets:
+   - Go to Settings → Secrets and variables → Actions
+   - Click "New repository secret"
+   - Name: `ANTHROPIC_API_KEY`
+   - Value: Their Anthropic API key
+
+5. **Offer customization:**
+   Ask if they want to customize any inputs (model, timeout, schedule, etc.)
+
+## Guidelines
+
+- Create workflows in `.github/workflows/` directory
+- Use descriptive filenames like `claude-pr-review.yml`
+- Don't overwrite existing workflows without asking
+- Remind about the API key secret requirement

+# GitHub Actions for Claude Code
+
+Reusable GitHub Actions workflows that integrate Claude Code into your CI/CD pipeline.
+
+## How It Works
+
+These are **reusable workflows** (using GitHub's `workflow_call` trigger). You don't copy them—you **call them** from your own repository using a simple caller workflow:
+
+```yaml
+# In YOUR repository: .github/workflows/claude-pr-review.yml
+jobs:
+  review:
+    uses: aviadr1/claude-code-showcase/.github/workflows/showcase-pr-review.yml@main
+    secrets:
+      ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+**Quick setup:** Run `/setup-github-actions` in Claude Code to interactively create caller workflows.
+
+---
+
+## Workflow Compatibility
+
+| Workflow | Stack | Notes |
+|----------|-------|-------|
+| [PR Review](#1-pr-review) | **Any** | Language-agnostic, uses git only |

+
+## Adapting for Other Stacks
+
+### Python Projects
+
+The Node.js workflows can be adapted for Python. Here's a guide:
+
+**Code Quality (Python adaptation):**
+```yaml
+# Create your own workflow based on showcase-nodejs-code-quality.yml
+# Replace npm steps with:
+- name: Setup Python
+  uses: actions/setup-python@v5
+  with:
+    python-version: '3.11'
+
+- name: Install dependencies
+  run: pip install -r requirements.txt
+
+# Change lint_command to: 'ruff check .' or 'flake8'
+```
+
+**Dependency Audit (Python adaptation):**
+```yaml
+# Use pip-audit instead of npm audit
+- name: Check dependencies
+  run: |
+    pip install pip-audit
+    pip-audit --json > /tmp/audit.json
+```
+
+### Go Projects
+
+**Code Quality (Go adaptation):**
+```yaml
+- name: Setup Go
+  uses: actions/setup-go@v5
+  with:
+    go-version: '1.21'
+
+# Change lint_command to: 'golangci-lint run'
+# Change file_extensions to: '.go'
+```
+
+### Rust Projects
+
+**Code Quality (Rust adaptation):**
+```yaml
+- name: Setup Rust
+  uses: actions-rust-lang/setup-rust-toolchain@v1
+
+# Change lint_command to: 'cargo clippy -- -D warnings'
+# Change file_extensions to: '.rs'
+```
+
+---
+
+## Setup Requirements
+
+### 1. Add Anthropic API Key
+
+Add `ANTHROPIC_API_KEY` to your repository secrets:
+1. Go to Settings → Secrets and variables → Actions
+2. Click "New repository secret"
+3. Name: `ANTHROPIC_API_KEY`
+4. Value: Your Anthropic API key
+
+### 2. Configure Permissions
+
+Ensure your workflow has appropriate permissions:
+```yaml
+permissions:
+  contents: write       # For creating branches
+  pull-requests: write  # For creating PRs
+  issues: read          # For reading issue comments (PR review)
+```
+
+### 3. Allow Workflow Calls (for reusable workflows)
+
+If your repository is private, you may need to allow workflow calls from other repositories in Settings → Actions → General.
+
+---
+
+## Model Aliases
+
+All workflows use auto-updating model aliases:
+
+| Alias | Description |
+|-------|-------------|
+| `opus` | Latest Claude Opus (best for complex analysis) |
+| `sonnet` | Latest Claude Sonnet (balanced speed/quality) |
+| `haiku` | Latest Claude Haiku (fastest, most economical) |
+
+---
+
+## Quick Start
+
+Run `/setup-github-actions` to interactively set up these workflows in your repository.
+
+---
+
+## Best Practices
+
+1. **Start with PR Review** - Works with any stack, immediate value
+2. **Use generic workflows first** - PR Review and Docs Sync work everywhere
+3. **Customize `code_patterns`** - Match your project's file extensions
+4. **Fork for other stacks** - Use Node.js workflows as templates for Python/Go/Rust
+5. **Set appropriate timeouts** - Complex codebases may need longer timeouts

+            # Documentation Sync
+
+            You are running a documentation sync. Check the environment variables for context:
+            - SINCE_DATE: Date to check changes from
+            - CHANGED_FILES: List of modified code files
+            - DOCS_PATHS: Documentation paths to update
+            - BASE_BRANCH: Branch to create PRs against
+
+            ## Your Tasks
+
+            1. **Read the changed files list** from the CHANGED_FILES environment variable
+
+            2. **Analyze Changes**: Review the changed files to understand what functionality was added, modified, or removed.
+
+            3. **Find Related Documentation**: Search for documentation in the paths specified by DOCS_PATHS.
+
+            4. **Check for Actual Problems**: For each code change, determine if existing docs are now WRONG:
+               - Do code examples still work?
+               - Are API signatures/types now incorrect?
+               - Are prop interfaces outdated?
+
+            5. **Fix Only What is Broken**: If you find documentation that is actually wrong:
+               - Fix incorrect code examples
+               - Update wrong API signatures and types
+               - Add docs ONLY for significant new features that have zero documentation
+
+            6. **Create a PR**: If you made any changes:
+               - Create a new branch from the BASE_BRANCH
+               - Commit all documentation updates
+               - Create a PR with a summary of what was fixed
+
+            ## CRITICAL Guidelines
+            - Documentation is a LIVING DOCUMENT - only fix things that are actually WRONG
+            - DO NOT add changelog-style entries
+            - ONLY update docs when they are incorrect or misleading
+            - If no problems are found, report that and DO NOT create a PR

+
+            ## Target Directory
+            **Review: `{0}`**
+
+            ## Your Tasks
+
+            1. **Read the code review standards**: If `{1}` exists, read it for the full checklist
+
+            2. **Analyze all files in the directory**:
+               - List all code files (excluding .test., .spec., .stories.)
+               - Read each file thoroughly
+               - Apply the review checklist
+
+            3. **Focus on finding and FIXING issues**:
+               - TypeScript strict mode violations (any types, missing types)
+               - React anti-patterns (bad useEffect, unnecessary memoization)
+               - Code style issues (mutations, deep nesting, poor naming)
+               - Missing error handling
+               - Security issues
+               - Performance problems
+
+            4. **Make the fixes yourself**:
+               - Do not just report issues - FIX THEM
+               - Use Edit tool to update files
+               - Ensure fixes do not break anything
+
+            5. **Run verification**:
+               - Run `{2}` - verify no lint errors introduced
+               - If errors occur, fix them or revert changes
+
+            6. **Create PR if fixes were made**:
+               - Create a branch from {3}
+               - Commit all fixes with descriptive message
+               - PR title: "fix({0}): code quality improvements"
+               - PR body should list fixes applied
+
+            ## Guidelines
+            - Be thorough but focused on this directory only
+            - Fix issues that are clear improvements
+            - Do not refactor working code just for style
+            - If no issues found, report that and skip PR creation

+
+            5. **Create PR** if any updates were made:
+               - Create branch from {2}
+               - Commit package.json and package-lock.json changes
+               - PR title: "chore(deps): update dependencies"
+               - PR body should list:
+                 - Each package updated with old to new version
+                 - Security vulnerabilities fixed (if any)
+
+            ## Guidelines
+            - Be CONSERVATIVE - when in doubt, do not update
+            - If tests fail after an update, revert that update
+            - Group related updates together
+            - If NO updates are possible, report that and do not create a PR
+            ', inputs.lint_command, inputs.test_command, inputs.base_branch) }}
+
+      - name: Report no updates needed
+        if: steps.check-outdated.outputs.has_outdated == 'false' && steps.security-audit.outputs.vulnerabilities == '0'
+        run: |
+          echo "All dependencies are up to date and no security vulnerabilities found."
+          echo "No action needed."

+### Showcase Workflows (Reusable)
+
+This repository provides **reusable GitHub Actions workflows** that you can call from your own repositories using GitHub's `workflow_call` feature. No need to copy workflow files—just reference them directly.
+
+**Quick Setup:**
+```yaml
+# In your repository's .github/workflows/claude-pr-review.yml
+name: Claude PR Review
+
+on:
+  pull_request:
+  issue_comment:
+    types: [created]
+
+jobs:
+  review:
+    uses: aviadr1/claude-code-showcase/.github/workflows/showcase-pr-review.yml@main
+    secrets:
+      ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+**Available Showcase Workflows:**
+
+| Workflow | Stack | Purpose | Key Inputs |
+|----------|-------|---------|------------|
+| [`showcase-pr-review.yml`](.github/workflows/showcase-pr-review.yml) | **Any** | Automatic PR review | `model`, `timeout_minutes`, `review_prompt` |
+| [`showcase-docs-sync.yml`](.github/workflows/showcase-docs-sync.yml) | **Any** | Keep docs in sync with code | `days_back`, `docs_paths`, `code_patterns` |
+| [`showcase-nodejs-code-quality.yml`](.github/workflows/showcase-nodejs-code-quality.yml) | **Node.js** | Periodic code quality audits | `num_dirs`, `source_dir`, `lint_command` |
+| [`showcase-nodejs-dependency-audit.yml`](.github/workflows/showcase-nodejs-dependency-audit.yml) | **Node.js** | Dependency updates & security | `node_version`, `lint_command`, `test_command` |
+
+**📄 Full documentation:** [github-actions skill](.claude/skills/github-actions/SKILL.md)
+
+**🛠️ Interactive setup:** Run `/setup-github-actions` in Claude Code
