When should I trigger the Guardian skill?

You should use it during architectural design, before every deployment, or when troubleshooting performance issues in your Cloudflare Workers.

Can this skill help with security audits?

Yes, it scans for plaintext secrets, open CORS policies, missing authentication routes, and exposed admin endpoints within your configuration.

Does it support Workers AI and Vectorize?

Yes, it provides specific guidance on model selection, token costs, and vector scaling limits to keep your AI infrastructure efficient and within budget.

How does the Guardian skill prevent high Cloudflare bills?

It proactively detects 'cost traps' such as unindexed D1 queries, unbuffered R2 writes, and expensive Durable Object patterns, warning you before code is even deployed.

Infraestructura en la Nube

Audits Cloudflare configurations to proactively identify security vulnerabilities, cost traps, and performance gaps before deployment.

Cloudflare Guardian acts as a virtual Senior SRE and FinOps engineer integrated into your Claude Code environment. It automatically reviews Wrangler configurations and infrastructure-as-code to prevent expensive mistakes like D1 row read explosions, unbuffered R2 writes, and unindexed database queries. By providing real-time warnings and best-practice implementation patterns for Durable Objects, Workers AI, and R2 storage, it ensures your Cloudflare architecture is secure, resilient, and cost-optimized without requiring manual oversight.
