Choose the control layer first for agents
The choice: one place for permission and intervention
Choose a control layer that defines for each agent workflow which tools may be accessed, which actions are allowed, who owns it, and when human intervention is needed. That is a better first production decision than treating an agent interface as a standalone starting point. The NIST passage categorizes tool use from authentication and computer use to code execution, software extensions, physical extensions, human interaction, and agent interaction. The same passage states that constraints depend on tool permissions and the action environment. This supports a narrow, concrete design rule: do not give every agent the same authority, and distinguish between read-only access and actions that change state. This is not a claim that one platform solves all agent problems; the passage describes a taxonomy and constraints, not a prescribed product architecture.
Make logging a control point, not a by-product
Use that layer to define which action, permission, and outcome you must be able to trace. The supplied EU passage cites, for high-risk AI systems, adequate risk assessment and mitigation, data quality, activity logging for traceability, and detailed documentation. Its scope is therefore specific: this passage concerns obligations for high-risk AI systems before they are placed on the market. It does not follow that every internal agent is automatically high risk or subject to the same obligations. Still, it is a useful signal to treat logging as an explicit architectural choice, especially where an agent can make changes or has access to sensitive processes.
Use a decision register for each workflow
For a single agent workflow, create a decision register containing: owner, allowed tool permissions, action environment, required log data, cost ceiling, data route, human escalation, and switching options. Complete it before adding more agent tools; this makes clear whether a session, data source, or configuration is tied to a single interface. This register is an editorial aid, not a standard from the supplied sources. The supplied passages provide no technical standard for session history, cost limits, data access, or portability; teams must therefore assess those topics for each application. Nor do the supplied passages provide individualized legal, financial, or professional advice.
