guardrails — The checks around a model that block bad inputs and outputs — filters, validators, and permission rules the model itself can't override.
AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
system prompt — The standing instructions a model receives before any user input — defining its role, rules, tools, and tone for the whole conversation.
sandbox — An isolated environment where AI-generated code or agent actions run without being able to touch anything real.
