Limit access to repositories and API tokens

Regularly rotate sensitive credentials

Review build scripts to prevent injection vulnerabilities

Web dashboard shows current build status

CLI provides job status and history

Notifications for success/failure events

Logs for detailed failure analysis

APIs for automated monitoring and reporting

Define tests in repository and integrate into Travis CI

Use build matrices to validate cross-environment behavior

Check logs and fix failing builds promptly
