What the literature leaves open
Despite these advances, large-scale deployment remains constrained by a shared set of structural limitations. Current agentic AI systems rely heavily on non-deterministic, language-based reasoning that is opaque, difficult to audit, and poorly aligned with formal verification requirements. In high-stakes and regulated domains, this lack of interpretability is not a secondary concern but a primary barrier to adoption.
This review examined whether recurrent limitations in contemporary agentic systems point to a deeper structural disconnect between probabilistic reasoning, persistent state management, orchestration, and execution control. Methodologically, the study was conducted as a five-phase structural diagnostic review reported with reference to the PRISMA-ScR principles.
The Governance Gap in Contemporary LLM-Based Agentic Systems: A Structural Diagnostic Review · 2026 · DOIFinally, selected low-risk operational domains could be evaluated prospectively in live trials using predefined metrics such as task completion time, query-resolution time, protocol-deviation detection, data completeness, number of unresolved discrepancies, cost per operational task, audit-trail completeness, and user workload.
Towards a multi-agent Clinical Trial Center framework to support modern clinical trials · 2026 · DOIIt remains an open question whether uncertain rules, our other main focus, can be applied so directly and fruitfully to real contexts. The results and open problems of this subsection are summarised in Figure 2. Expressivity results and open problems about ISLAFs are summarised in Figure 3. As for immediate future work, the current paper leaves many open questions.

Design and Implementation of Agentic AI Pipelines for Enterprise Decision-Making Architecture Patterns for Production Systems · 2026 · DOIThe industry is recognizing the need for competing trust and authorization models, verifiable intent, and cross-platform orchestration. Autonomous systems are scaling faster than the coordination structures required to govern them.
The paper identifies the need for governance by construction to ensure safety and compliance. The gap is the lack of a principled governance layer for generalist computer-using agents.
A deeper reflection would distinguish which subquestions remain unresolved, such as whether dp53 directly regulates dMyc transcription, whether dMyc regulates dp53, whether the observed relationship is limited to apoptosis or cell competition, and whether available evidence supports direct regulation or only indirect interaction.
Time to REFLECT: Can We Trust LLM Judges for Evidence-based Research Agents? · 2026These challenges point to the need for reinforcement mechanisms, memory consolidation, and more robust selection strategies.
Our primary contribution has been to bridge the gap between the high-level theory of agentic AI and its practical, high-stakes application within the field of engineering. To achieve this, we first establish a clear and necessary taxonomy, distinguishing the unique capabilities of agentic AI from its predecessors.
Agentic AI systems in electrical power systems engineering: current state-of-the-art and challenges · 2026 · DOIThe central challenge of agentic AI is not autonomy itself, but accountable transition. Current agentic AI systems often lack explicit mechanisms for governing the transition from exploratory reasoning to operational effect.
Agentic AI is increasingly discussed as a prospective participant in business processes, yet it remains unclear how current implementations relate to this vision.
