How to Use AI Coding Tools Safely
AI-generated code can contain bugs, insecure patterns, outdated APIs and incorrect assumptions. Treat the output as a proposed change that needs review, not as automatically production-ready code.
- Review every change: understand what the generated code does before merging it.
- Use version control: commit your work before allowing an AI agent to make large changes.
- Run tests: execute relevant unit tests, integration tests and manual checks.
- Protect secrets: never paste passwords, API keys, private credentials or sensitive customer data into an AI tool without an approved security setup.
- Check dependencies: review newly added packages, versions and licenses.
- Limit permissions: inspect terminal commands and file operations before approving them.
- Test security-sensitive code: pay particular attention to authentication, authorization, database queries, file uploads and payment flows.
For production projects, use a staging environment and back up important data before applying substantial AI-generated changes.
