Mission-Critical RAG: Add Agents Only With Control

RAG improves model answers by grounding them in approved knowledge. Agents add action.

That combination is powerful only when retrieval quality, authority, and evidence are governed together.

The Executive Risk

A RAG system can cite the wrong source. An agent can act on it. The failure moves from answer quality to operating exposure.

Required Controls

• Authoritative knowledge sources
• Retrieval quality testing
• Tool permissions and action limits
• Human review for material decisions
• Logs that show source, reasoning, action, and owner

Bottom Line

Do not attach agents to RAG because the architecture is fashionable. Attach them only where the decision path is bounded, testable, and auditable.
