+### Claude Authentication Options
+
+This service supports three authentication methods:
+
+- **Setup Container**: Personal subscription authentication - [Setup Container Guide](./docs/setup-container-guide.md)
+- **ANTHROPIC_API_KEY**: Direct API key authentication - [Authentication Guide](./docs/claude-authentication-guide.md)
+- **AWS Bedrock**: Enterprise AWS integration - [Authentication Guide](./docs/claude-authentication-guide.md)
+
+#### Quick Start: Setup Container
+For personal subscription users:
+
+```bash
+# 1. Run interactive authentication setup
+./scripts/setup/setup-claude-interactive.sh
+
+# 2. In container: authenticate with your subscription
+claude --dangerously-skip-permissions  # Follow authentication flow
+exit                                    # Save authentication
+
+# 3. Test captured authentication
+./scripts/setup/test-claude-auth.sh

+# Claude Authentication Guide
+
+This guide covers three authentication methods for using Claude with the webhook service.
+
+## Authentication Methods Overview
+
+| Method | Use Case | Setup Complexity |
+|--------|----------|------------------|
+| **Setup Container** | Personal development | Medium |
+| **ANTHROPIC_API_KEY** | Production environments | Low |
+| **AWS Bedrock** | Enterprise integration | High |
+
+---
+
+## 🐳 Option 1: Setup Container (Personal Development)
+
+Uses personal Claude Code subscription for authentication.
+
+### Setup Process
+
+#### 1. Run Interactive Authentication Setup
+```bash
+./scripts/setup/setup-claude-interactive.sh
+```
+
+#### 2. Authenticate in Container
+When the container starts:
+```bash
+# In the container shell:
+claude --dangerously-skip-permissions  # Follow authentication flow
+exit                                   # Save authentication state
+```
+
+#### 3. Test Captured Authentication
+```bash
+./scripts/setup/test-claude-auth.sh
+```
+
+#### 4. Use Captured Authentication
+```bash
+# Option A: Copy to your main Claude directory
+cp -r ${CLAUDE_HUB_DIR:-~/.claude-hub}/* ~/.claude/
+
+# Option B: Mount in docker-compose
+# Update docker-compose.yml:
+# - ./${CLAUDE_HUB_DIR:-~/.claude-hub}:/home/node/.claude
+```
+
+#### 5. Verify Setup
+```bash
+node cli/webhook-cli.js --repo "owner/repo" --command "Test authentication" --url "http://localhost:8082"
+```
+
+### Troubleshooting
+- **Tokens expire**: Re-run authentication setup when needed
+- **File permissions**: Ensure `.credentials.json` is readable by container user
+- **Mount issues**: Verify correct path in docker-compose volume mounts
+
+---
+
+## 🔑 Option 2: ANTHROPIC_API_KEY (Production)
+
+Direct API key authentication for production environments.
+
+### Setup Process
+
+#### 1. Get API Key
+1. Go to [Anthropic Console](https://console.anthropic.com/)
+2. Create a new API key
+3. Copy the key (starts with `sk-ant-`)
+
+#### 2. Configure Environment
+```bash
+# Add to .env file
+ANTHROPIC_API_KEY=sk-ant-your-api-key-here
+```
+
+#### 3. Restart Service
+```bash
+docker compose restart webhook
+```
+
+#### 4. Test
+```bash
+node cli/webhook-cli.js --repo "owner/repo" --command "Test API key authentication" --url "http://localhost:8082"
+```
+
+### Best Practices
+- **Key rotation**: Regularly rotate API keys
+- **Environment security**: Never commit keys to version control
+- **Usage monitoring**: Monitor API usage through Anthropic Console
+
+---
+
+## ☁️ Option 3: AWS Bedrock (Enterprise)
+
+AWS-integrated Claude access for enterprise deployments.
+
+### Setup Process
+
+#### 1. Configure AWS Credentials
+```bash
+# Option A: AWS Profile (Recommended)
+./scripts/aws/create-aws-profile.sh
+
+# Option B: Environment Variables
+export AWS_ACCESS_KEY_ID=your_access_key
+export AWS_SECRET_ACCESS_KEY=your_secret_key
+export AWS_REGION=us-east-1
+```
+
+#### 2. Configure Bedrock Settings
+```bash
+# Add to .env file
+CLAUDE_CODE_USE_BEDROCK=1
+ANTHROPIC_MODEL=us.anthropic.claude-3-7-sonnet-20250219-v1:0
+AWS_REGION=us-east-1
+
+# If using profiles
+USE_AWS_PROFILE=true
+AWS_PROFILE=claude-webhook
+```
+
+#### 3. Verify Bedrock Access
+```bash
+aws bedrock list-foundation-models --region us-east-1
+```
+
+#### 4. Restart Service
+```bash
+docker compose restart webhook
+```
+
+#### 5. Test
+```bash
+node cli/webhook-cli.js --repo "owner/repo" --command "Test Bedrock authentication" --url "http://localhost:8082"
+```
+
+### Best Practices
+- **IAM policies**: Use minimal required permissions
+- **Regional selection**: Choose appropriate AWS region
+- **Access logging**: Enable CloudTrail for audit compliance
+
+---
+
+## 🚀 Authentication Priority and Fallback
+
+The system checks authentication methods in this order:
+
+1. **ANTHROPIC_API_KEY** (highest priority)
+2. **Claude Interactive Authentication** (setup container)
+3. **AWS Bedrock** (if configured)
+
+### Environment Variables
+
+```bash
+# Method 1: Direct API Key
+ANTHROPIC_API_KEY=sk-ant-your-key
+
+# Method 2: Claude Interactive (automatic if ~/.claude is mounted)
+# No environment variables needed
+
+# Method 3: AWS Bedrock
+CLAUDE_CODE_USE_BEDROCK=1
+ANTHROPIC_MODEL=us.anthropic.claude-3-7-sonnet-20250219-v1:0
+AWS_REGION=us-east-1
+AWS_ACCESS_KEY_ID=your_key_id
+AWS_SECRET_ACCESS_KEY=your_secret_key
+# OR
+USE_AWS_PROFILE=true
+AWS_PROFILE=your-profile-name
+```
+
+---
+
+## 🛠️ Switching Between Methods
+
+You can switch between authentication methods by updating your `.env` file:
+
+```bash
+# Development with personal subscription
+# Comment out API key, ensure ~/.claude is mounted
+# ANTHROPIC_API_KEY=
+# Mount: ~/.claude:/home/node/.claude
+
+# Production with API key
+ANTHROPIC_API_KEY=sk-ant-your-production-key
+
+# Enterprise with Bedrock
+CLAUDE_CODE_USE_BEDROCK=1
+ANTHROPIC_MODEL=us.anthropic.claude-3-7-sonnet-20250219-v1:0
+USE_AWS_PROFILE=true
+AWS_PROFILE=production-claude
+```
+
+---
+
+## 🔍 Troubleshooting
+
+### Authentication Not Working
+1. Check environment variables are set correctly
+2. Verify API keys are valid and not expired
+3. For Bedrock: Ensure AWS credentials have correct permissions
+4. For setup container: Re-run authentication if tokens expired
+
+### Rate Limiting
+- **API Key**: Contact Anthropic for rate limit information
+- **Bedrock**: Configure AWS throttling settings
+- **Setup Container**: Limited by subscription tier

+# Setup Container Authentication
+
+The setup container method captures Claude CLI authentication state for use in automated environments by preserving OAuth tokens and session data.
+
+## Overview
+
+Claude CLI requires interactive authentication. This container approach captures the authentication state from an interactive session and makes it available for automated use.
+
+**Prerequisites**: Requires active Claude Code subscription.
+
+## How It Works
+
+```mermaid
+graph TD
+    A[Setup Container] --> B[Interactive Claude Login]
+    B --> C[OAuth Authentication]
+    C --> D[Capture Auth State]
+    D --> E[Mount in Production]
+    E --> F[Automated Claude Usage]
+```
+
+### 1. Interactive Authentication
+- Clean container environment with Claude CLI installed
+- User runs `claude --dangerously-skip-permissions` and completes authentication
+- OAuth tokens and session data stored in `~/.claude`
+
+### 2. State Capture
+- Complete `~/.claude` directory copied to persistent storage on container exit
+- Includes credentials, settings, project data, and session info
+- Preserves all authentication context
+
+### 3. Production Mount
+- Captured authentication mounted in production containers
+- Working copy created for each execution to avoid state conflicts
+- OAuth tokens used automatically by Claude CLI
+
+## Technical Benefits
+
+- **OAuth Security**: Uses OAuth tokens instead of API keys in environment variables
+- **Session Persistence**: Maintains Claude CLI session state across executions
+- **Portable**: Authentication state works across different container environments
+- **Reusable**: One-time setup supports multiple deployments
+
+## Files Captured
+
+The setup container captures all essential Claude authentication files:
+
+```bash
+~/.claude/
+├── .credentials.json          # OAuth tokens (primary auth)
+├── settings.local.json        # User preferences
+├── projects/                  # Project history
+├── todos/                     # Task management data
+├── statsig/                   # Analytics and feature flags
+└── package.json              # CLI dependencies
+```
+
+### Critical File: .credentials.json
+```json
+{
+  "claudeAiOauth": {
+    "accessToken": "sk-ant-oat01-...",
+    "refreshToken": "sk-ant-ort01-...",
+    "expiresAt": 1748658860401,
+    "scopes": ["user:inference", "user:profile"]
+  }
+}
+```
+
+## Container Implementation
+
+### Setup Container (`Dockerfile.claude-setup`)
+- Node.js environment with Claude CLI
+- Interactive shell for authentication
+- Signal handling for clean state capture
+- Automatic file copying on exit
+
+### Entrypoint Scripts
+- **Authentication copying**: Comprehensive file transfer
+- **Permission handling**: Correct ownership for container user
+- **Debug output**: Detailed logging for troubleshooting
+
+## Token Lifecycle and Management
+
+### Token Expiration Timeline
+Claude OAuth tokens typically expire within **8-12 hours**:
+- **Access tokens**: Short-lived (8-12 hours)
+- **Refresh tokens**: Longer-lived but also expire
+- **Automatic refresh**: Claude CLI attempts to refresh when needed
+
+### Refresh Token Behavior
+```json
+{
+  "claudeAiOauth": {
+    "accessToken": "sk-ant-oat01-...",     // Short-lived
+    "refreshToken": "sk-ant-ort01-...",   // Used to get new access tokens
+    "expiresAt": 1748658860401,           // Timestamp when access token expires
+    "scopes": ["user:inference", "user:profile"]
+  }
+}
+```
+
+### Automatic Refresh Strategy
+The Claude CLI automatically attempts to refresh tokens when:
+- Access token is expired or near expiration
+- API calls return authentication errors
+- Session state indicates refresh is needed
+
+However, refresh tokens themselves eventually expire, requiring **full re-authentication**.
+
+### Maintenance Requirements
+
+**Monitoring**
+- Check authentication health regularly
+- Monitor for expired token errors in logs
+
+**Re-authentication**
+- Required when OAuth tokens expire
+- Test authentication validity after updates
+
+### Current Limitations
+
+- Token refresh requires manual intervention
+- No automated re-authentication when tokens expire
+- Manual monitoring required for authentication health
+
+## Advanced Usage
+
+### Multiple Environments
+```bash
+# Development
+./${CLAUDE_HUB_DIR:-~/.claude-hub} → ~/.claude/
+
+# Staging
+./claude-auth-staging → staging container
+
+# Testing
+./claude-auth-test → test container
+```
+
+## Security Considerations
+
+### Token Protection
+- OAuth tokens are sensitive credentials
+- Store in secure, encrypted storage
+- Rotate regularly by re-authenticating
+
+### Container Security
+- Mount authentication with appropriate permissions
+- Use minimal container privileges
+- Avoid logging sensitive data
+
+### Network Security
+- HTTPS for all Claude API communication
+- Secure token transmission
+- Monitor for token abuse
+
+## Monitoring and Maintenance
+
+### Health Checks
+```bash
+# Test authentication status
+./scripts/setup/test-claude-auth.sh
+
+# Verify token validity
+docker run --rm -v "./${CLAUDE_HUB_DIR:-~/.claude-hub}:/home/node/.claude:ro" \
+  claude-setup:latest claude --dangerously-skip-permissions
+```
+
+### Refresh Workflow
+```bash
+# When authentication expires
+./scripts/setup/setup-claude-interactive.sh
+
+# Update production environment
+cp -r ${CLAUDE_HUB_DIR:-~/.claude-hub}/* ~/.claude/
+docker compose restart webhook
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Empty .credentials.json
+**Symptom**: Authentication fails, file exists but is 0 bytes
+**Cause**: Interactive authentication wasn't completed
+**Solution**: Re-run setup container and complete authentication flow
+
+#### 2. Permission Errors
+**Symptom**: "Permission denied" accessing .credentials.json
+**Cause**: File ownership mismatch in container
+**Solution**: Entrypoint scripts handle this automatically
+
+#### 3. OAuth Token Expired
+**Symptom**: "Invalid API key" or authentication errors
+**Cause**: Tokens expired (natural expiration)
+**Solution**: Re-authenticate using setup container
+
+#### 4. Mount Path Issues
+**Symptom**: Authentication files not found in container
+**Cause**: Incorrect volume mount in docker-compose
+**Solution**: Verify mount path matches captured auth directory
+
+### Debug Commands
+
+```bash
+# Check captured files
+ls -la ${CLAUDE_HUB_DIR:-~/.claude-hub}/
+
+# Test authentication directly
+docker run --rm -v "$(pwd)/${CLAUDE_HUB_DIR:-~/.claude-hub}:/tmp/auth:ro" \
+  --entrypoint="" claude-setup:latest \
+  bash -c "cp -r /tmp/auth /home/node/.claude && 
+           sudo -u node env HOME=/home/node \
+           /usr/local/share/npm-global/bin/claude --dangerously-skip-permissions --print 'test'"
+
+# Verify OAuth tokens
+cat ${CLAUDE_HUB_DIR:-~/.claude-hub}/.credentials.json | jq '.claudeAiOauth'
+```

+
+*The setup container approach provides a technical solution for capturing and reusing Claude CLI authentication in automated environments.*
