What are agent boundaries?

Agent boundaries are the hard constraints on what an enterprise AI agent can access, call, decide, and escalate. Four components matter: data scopes, tool whitelists, confidence thresholds, and escalation rules.

Every production agent ships with all four defined, tested, and logged. Anything less is an accident waiting to ship. NIST AI RMF Manage and Govern functions, SR 11-7, and ISO/IEC 42001 all point to bounded agent behavior as a baseline control.

What data scopes should each agent have?

Data scopes restrict what an agent reads. Inherit the calling user’s context. Apply row-level security on retrieval. Gate PHI and PII through HIPAA minimum-necessary classifiers. Bound access by time and tenant.

Concrete fields per agent: allowed source systems, row filters, classification ceiling (public, internal, confidential, restricted), retention window, tenant ID. SOX auditability and HITECH require these to be logged per call. NY DFS Part 500 and Colorado AI Act read this telemetry during exam.

How should tool whitelists and rate limits work?

Tool whitelists enumerate the exact functions an agent can invoke. No reflection. No dynamic tool loading. Rate limits cap calls per tool per minute. Idempotency keys protect write actions from retries.

Each tool gets a max action cost per run, a per-tenant rate ceiling, and a destructive-action flag that forces a human gate. OCC third-party risk bulletins and DORA ICT controls treat this layer as the control surface for vendor and model risk.

How do confidence thresholds route decisions?

Confidence thresholds split decisions into three tiers. Above the high bar, the agent acts. In the middle band, a human reviews. Below the low bar, the agent stops and logs the reason.

Calibrate per risk tier. A low-risk classification can auto-approve at 0.85. A FCRA adverse-action recommendation should not auto-approve at all. NAIC Model AI Bulletin and SR 11-7 expect documented threshold rationale, drift monitoring, and recalibration cadence.

What escalation rules prevent unsupervised drift?

Escalation rules name who or what receives the handoff: a human reviewer, a supervisor agent, or a hard-stop with audit log. Timeouts force escalation if no decision lands within a set window.

Each rule lists trigger condition, target queue, SLA, and fallback. EU AI Act human oversight expectations, GDPR Article 22 automated-decisioning context, and Singapore MAS FEAT all address routed escalation. India DPDP, UAE PDPL, and Canada AIDA add jurisdiction-specific data-handling notes that vary by deployment region.

What to do next

Write your boundary config before you write your first prompt. Define data scopes, tool whitelist, confidence thresholds, and escalation rules in a single JSON block per agent. Version it. Review it on every release.
