The premise
Hardcoded API keys end up in public GitHub or tomorrow's incident — vaults exist for a reason.
What AI does well here
Pull secrets at runtime, never bake them into images
Rotate provider keys on a schedule
What AI cannot do
Stop a malicious insider with valid access
Replace per-tenant credential isolation
Practice this safely
Use a small project example from your own work. The useful move is to compare the AI's draft against your goal, sources, and constraints before you trust it.
Ask AI to explain secrets management in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "Choosing a secrets vault for AI agent credentials" and ask for two possible next steps plus one reason each step might be wrong.
Check credentials against a trusted source, teacher, adult, expert, or original document before you use it.
