+# 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+| **Node.js Dependency Audit** | Node.js | Check for outdated/vulnerable dependencies (requires npm) |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
