OAuth 2.1 & Prompt Versioning for Production AI Agents
Answer-first: Production AI API design requires securing agent identities using OAuth 2.1 client credentials, versioning prompts inside CI/CD gates to prevent quality regression, and tracking runtime costs. Monitoring token usage and accuracy ensures robust operational predictability. What You’ll Learn That AI Won’t Tell You Secure prompt versioning practices using git commits and CI checks.
