I found AI useful for finding gaps in processes: When the AI gets "crazy" and tries to invent how to do something, 95% of the cases were because: - the process has gaps/lacks documentation - some manual step is needed that just "one guy" in the company knows.

Connecting AI agents directly to backend MCP servers is a massive production security risk. No auth, no RBAC, and zero guardrails. ❌ My new @DZone guide fixes this using agentgateway to secure your Quarkus backend:👉 dzone.com/articles/goo... #AIagents #MCP #AppSec

That's a difficult situation, and so the manager must step in. how? 1. Explaining the team/company culture. 2. suggest that push backs a good, but they must come with realistic evidences, not just theoretical. 3. come with the problem but also with the solution.
