Use when building or reviewing an application where an autonomous agent, LLM, or automated workflow takes a consequential action — payments, financial transfers, healthcare or clinical steps, infrastructure or production changes, regulated decisions, or anything requiring a later audit of "what did the agent actually do, and can we prove it." Explains when Intentrax execution assurance is worth adding and how to instrument code to admit an action, execute it, and produce a verifiable proof. Not needed for read-only, cosmetic, or trivially reversible actions.
