MANUAL CONFIGURATION REQUIRED

================================================================

To complete the setup, you need to manually configure the following in GitHub:

### Step 1: GitHub Actions Permissions

1. Go to: https://github.com/$REPO/settings/actions

2. Scroll down to "Workflow permissions"

3. Select: "Read and write permissions"

4. Check: "Allow GitHub Actions to create and approve pull requests"

5. Click "Save"

### Step 2: Enable Auto-Merge

1. Go to: https://github.com/$REPO/settings

2. Under "Pull Requests" section

3. Check: "Allow auto-merge"

4. Click "Save"

This will allow the automated update workflow to:

- Create pull requests

- Automatically merge them when CI passes

================================================================

After completing these steps, you can test the workflow by running:

gh workflow run "Update Claude Code Version"

EOF

# Create a settings documentation file

echo "Creating settings documentation..."

cat > .github/REPOSITORY_SETTINGS.md << 'EOF'

# Repository Settings Configuration

This repository requires specific GitHub settings to enable automated updates.

## Required Settings

### GitHub Actions Permissions

1. Navigate to Settings → Actions → General

2. Under "Workflow permissions":

- Select **"Read and write permissions"**

- Check **"Allow GitHub Actions to create and approve pull requests"**

3. Click Save

These settings allow the `update-claude-code.yml` workflow to:

- Modify files in the repository

- Create pull requests for version updates

- Update the flake.lock file

## Verification

After configuring the settings, you can verify the workflow works by:

```bash

# Manually trigger the update workflow

gh workflow run "Update Claude Code Version"

# Check the workflow status

gh run list --workflow="Update Claude Code Version"

```

## Troubleshooting

If you see the error "GitHub Actions is not permitted to create or approve pull requests":

- Ensure the settings above are properly configured

- The repository must not have branch protection rules that prevent GitHub Actions from creating PRs

- The workflow uses the built-in `GITHUB_TOKEN` which is automatically provided
