Taxonomy Confusion Is Leaving Agentic AI Governance Without a Foundation

What happened

Why it matters

• ·Without a shared definition of what makes an AI system "agentic," procurement contracts cannot specify what controls a vendor must maintain. Compliance teams may be acquiring systems with broad autonomous authority under terms written for narrower tools, creating unmanaged accountability gaps.
• ·Red-teaming and pre-deployment evaluation programs are scoped against what a system is expected to do. Taxonomy confusion means evaluators and vendors may be testing different threat models, leaving real risks unexamined before deployment in sensitive environments.
• ·Regulatory exposure compounds when definitions diverge across jurisdictions. The Five Eyes Guidance on the Careful Adoption of Agentic AI Services and the Implementation Opinions on the Administration of Intelligent Agents each treat agentic systems differently. Firms operating across borders need an internal taxonomy that maps to both, or they risk compliance gaps they cannot even see.

Governance controls affected

What to do now

• ☐Audit every internal policy, contract, and system intake form that uses the word 'agentic' or 'autonomous' and confirm it defines what level of delegated authority and independent action it covers.
• ☐Ask your procurement team to add three classification questions to AI vendor intake: where in the workflow does the system operate, what actions can it take without human approval, and who is named as accountable when it causes harm.
• ☐Review your current red-teaming scope with your security team and confirm it reflects the actual authority level of each agent, not just its stated purpose.
• ☐Map your internal AI agent inventory against the three CSIS attributes (workflow position, delegated authority, accountability) and flag any system where accountability is unassigned or ambiguous.
• ☐Where your organization operates in defense, critical infrastructure, or regulated sectors, confirm that your agent classification language aligns with the definitions used by the agencies or regulators that will review your systems.

What to watch next

CSIS is likely to follow this paper with sector-specific guidance as agentic AI deployment in defense and critical infrastructure accelerates. Compliance teams should watch for any adoption of the CSIS taxonomy in federal procurement standards or Five Eyes Guidance on the Careful Adoption of Agentic AI Services updates. The US AI AGENT Act discussion draft is a parallel legislative signal worth tracking, as it may codify definitional requirements that resolve the ambiguity CSIS identifies. If either instrument adopts formal definitions, organizations without an internal taxonomy will need to retrofit classification across their entire agent inventory.
