AI agents fail at the auth step more than at the reasoning step. anyone else seeing this?

Summary

AI agents often fail due to authentication hurdles like email verification, OTP timeouts, and captchas, not due to reasoning errors, highlighting infrastructure challenges in production.

been building AI agents for a while and noticing a pattern: the LLM reasoning part works. the part that breaks is everything around accounts, logins, and verification. agent gets to "sign up for this service" and then: \- email verification loop breaks \- OTP times out while the agent is mid-step \- captcha or bot detection fires \- session expires between steps the model figured out what to do. the infrastructure around it didn't cooperate. curious if this matches what others are building. where do your agents actually fail in production? is it the reasoning, or is it the plumbing?
