Add Devin Playbook Sync workflow

Summary

Adds a GitHub Actions workflow that automatically syncs markdown files from a playbooks/ directory to Devin using the newly created Playbook Sync action. The workflow triggers automatically on pushes to main when .md files in the playbooks/ directory change, and can also be triggered manually via workflow_dispatch.

Key features:

• Automatic sync on push to main (when playbooks/*.md files change)
• Manual trigger with operation choice (sync or list)
• Outputs playbook IDs and sync count for verification
• Handles empty directory gracefully with warning message

Review & Testing Checklist for Human

⚠️ CRITICAL - This workflow has NOT been tested with real API calls yet.

• Configure DEVIN_API_KEY secret - Navigate to Settings → Secrets and variables → Actions → New repository secret. Add your Devin API key from Devin Settings. Without this, the workflow will fail immediately.

• Test end-to-end with a real playbook - After configuring the secret:

  # Create playbooks directory and add a test file
  mkdir -p playbooks
  echo "# Test Playbook\n\nThis is a test playbook." > playbooks/test.md
  git add playbooks/test.md
  git commit -m "Add test playbook"
  git push origin main
  
  # Monitor workflow: Actions tab → "Sync Playbooks to Devin"
  # Verify playbook appears in Devin: https://app.devin.ai/settings

• Test edge cases - Verify the action handles:

  • Markdown files with special characters (quotes, backticks, code blocks)
  • Large markdown files (>10KB)
  • Empty playbooks/ directory (should show warning, not fail)
  • Invalid API key (should fail with clear error)

• Update action reference after merge - Currently uses @devin/1762305531-playbook-sync-action (PR branch). Change to @v1 after PR #2 in DEVIN-GITHUB-ACTIONS is merged and tagged.

• Test manual workflow dispatch - Go to Actions → "Sync Playbooks to Devin" → Run workflow → Test both "sync" and "list" operations.

Notes

Limitations:

• The playbooks/ directory doesn't exist yet in this repo. Create it before testing.
• Any .md file pushed to playbooks/ on main will automatically sync. Consider using a separate branch for draft playbooks if needed.
• The underlying action was tested only in dry-run mode. Real API behavior may differ slightly.

Action reference:

• Currently references the PR branch because the action isn't released yet
• All CI tests pass on that branch (3/3 checks passing)
• Documentation: DEVIN-GITHUB-ACTIONS README

Session info:

• Devin session: https://app.devin.ai/sessions/2a458c6f714c4d55a180f6a617c264fb
