🔑 Enhanced Key Takeaways
- •The CLI integration leverages Vercel's existing Infrastructure-as-Code (IaC) philosophy, allowing firewall configurations to be version-controlled alongside application code in Git repositories.
- •The 'Vercel Firewall skill' for agents utilizes a structured JSON schema for rule definitions, enabling automated security policy generation based on real-time traffic analysis and threat intelligence feeds.
- •This update introduces a 'dry-run' validation mode within the CLI, which simulates rule impact against historical traffic logs before applying changes to production environments to prevent accidental service outages.
