The pith

Open-world agents create an authorization-execution gap where intended permissions diverge from executed actions, producing hard-to-undo harm.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

This position paper claims that open-world agents, which operate autonomously across tools, persistent state, and handoffs, routinely execute actions that diverge from what their principals intended to authorize. The resulting Authorization-Execution Gap can produce irreversible damage because the agents act in open environments where mistakes cannot be rolled back. The authors trace many observed failures to three structural sources: incomplete delegation of authority at the outset, corruption or loss along communication channels, and fragmentation when multiple actions or agents are composed together. Because the same failure can originate from any of these sources, defenses that only address symptoms fail to fix the underlying problem. The paper therefore argues that safety requires source-oriented diagnosis and integrity checks applied while the agent is running, not merely upfront filtering or later audits.

Core claim

The central claim is that the Authorization-Execution Gap (AEG) is a major safety and security problem in open-world agents. The AEG is the divergence between what a principal intends to authorize and what the agent ultimately executes. This divergence arises dynamically from three structural sources: delegation-level incompleteness, channel-level corruption, and composition-level fragmentation. The same observed failure may stem from any source, so defenses must diagnose the source during execution and apply runtime authorization integrity checks rather than relying on one-time upfront filters or post-hoc audits.

What carries the argument

The Authorization-Execution Gap, the divergence between intended authorization and actual execution, carried through three structural sources: delegation-level incompleteness, channel-level corruption, and composition-level fragmentation.

If this is right

  • Defenses must identify the structural source of any authorization divergence rather than treating symptoms alone.
  • Authorization integrity must be checked continuously during execution because the sources arise dynamically.
  • Papers on open-world agents should report process-level evidence of where AEG was detected, constrained, and attributed to a source.
  • The same failure can arise from any of the three sources, making source-agnostic metrics insufficient for security evaluation.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • Existing agent tool-use frameworks could be audited level-by-level to measure how often delegation incompleteness occurs in practice.
  • Multi-agent handoff protocols may need explicit authorization tokens passed between agents to reduce composition-level fragmentation.
  • Runtime checks could be tested by injecting controlled corruption into channels and measuring whether source diagnosis improves recovery rates.

Load-bearing premise

That most agent failures can be traced to these three structural sources and that source-oriented runtime integrity checks can be implemented without blocking useful agent behavior.

What would settle it

An open-world agent failure that cannot be attributed to delegation incompleteness, channel corruption, or composition fragmentation, or a working agent system that maintains safety using only upfront filters and post-hoc audits with no runtime checks.

This position paper argues that the Authorization-Execution Gap (AEG) is a major safety and security problem in open-world agents. The AEG is the divergence between what a principal intends to authorize and what an open-world agent ultimately executes. Because such agents act autonomously across tools, persistent state, and multi-agent handoffs, even small instances of authorization divergence can cause harm that is difficult or impossible to undo. We argue that many observed agent failures can be traced to three structural sources of AEG: delegation-level incompleteness, channel-level corruption, and composition-level fragmentation. The same observed failure may arise from any of these sources. Without identifying the source, a defense targeting the symptom alone cannot address the underlying cause. Agent safety and security should therefore emphasize source-oriented diagnosis and defense. Because the structural sources of AEG arise dynamically during execution, this approach necessarily requires authorization integrity checks applied during execution, rather than relying solely on one-shot upfront filtering or post-hoc audit. For NeurIPS, the implication is that papers on open-world agents should report not only outcome-level metrics such as task success or attack resistance, but also process-level evidence showing where AEG was detected, constrained, and attributed to a structural source during execution.

Referee Report

2 major / 2 minor

Summary. This position paper introduces the Authorization-Execution Gap (AEG) as the divergence between a principal's intended authorization and what an open-world agent actually executes. It argues that AEG is a major safety and security problem because even small divergences can cause irreversible harm in autonomous, tool-using, multi-agent settings. The paper traces many observed failures to three structural sources—delegation-level incompleteness, channel-level corruption, and composition-level fragmentation—and concludes that defenses must be source-oriented and applied at runtime rather than relying solely on upfront filtering or post-hoc audits. It recommends that NeurIPS papers on open-world agents report process-level evidence of AEG detection, constraint, and source attribution.

Significance. If the framework holds, it offers a coherent conceptual lens for analyzing why current authorization mechanisms fall short in dynamic agent environments and could usefully redirect research toward runtime integrity diagnostics. The position correctly notes that symptom-focused defenses may miss root causes and that process-level reporting would complement existing outcome metrics such as task success or attack resistance. As a purely conceptual contribution without empirical cases, formal models, or implementation details, its significance lies in framing future work rather than in immediate technical advance.

major comments (2)
  1. [Abstract / structural sources section] Abstract and the section introducing the three structural sources: the central claim that 'many observed agent failures can be traced to' delegation-level incompleteness, channel-level corruption, and composition-level fragmentation is load-bearing for the argument that source-oriented runtime checks are required, yet the manuscript supplies no case studies, failure traces, or references to concrete incidents to substantiate the tracing or to show that these three sources are comprehensive.
  2. [runtime checks / defense implications section] The section arguing for runtime integrity checks: the assertion that dynamic sources of AEG 'necessarily require' execution-time checks (rather than static or post-hoc methods) is logically consistent with the premises but lacks any discussion of implementation feasibility, performance cost, or how such checks could be realized without unduly constraining useful agent behavior; this directly affects the practicality of the recommended defense strategy.
minor comments (2)
  1. The three sources are introduced at a high level; brief illustrative examples or a diagram showing how each source produces AEG in a concrete agent workflow would improve clarity without altering the conceptual argument.
  2. The NeurIPS recommendation paragraph could be expanded with one or two concrete examples of process-level metrics (e.g., 'fraction of tool calls where delegation incompleteness was detected at runtime') to make the reporting suggestion more actionable.

  1. Referee: [Abstract / structural sources section] Abstract and the section introducing the three structural sources: the central claim that 'many observed agent failures can be traced to' delegation-level incompleteness, channel-level corruption, and composition-level fragmentation is load-bearing for the argument that source-oriented runtime checks are required, yet the manuscript supplies no case studies, failure traces, or references to concrete incidents to substantiate the tracing or to show that these three sources are comprehensive.

    Authors: We acknowledge that the manuscript does not currently include explicit case studies or failure traces. As a position paper, the three sources are proposed as a conceptual categorization derived from patterns across the existing agent safety and security literature rather than from new empirical analysis. In the revised version we will add targeted references to documented incidents and prior work illustrating each source (e.g., incomplete delegation in tool-use failures, channel corruption via prompt or state injection, and fragmentation in multi-agent handoffs). This will substantiate the tracing claim while preserving the paper's focus on framing rather than exhaustive validation. We will also note that the categorization is offered as a starting point open to refinement. revision: yes

  2. Referee: [runtime checks / defense implications section] The section arguing for runtime integrity checks: the assertion that dynamic sources of AEG 'necessarily require' execution-time checks (rather than static or post-hoc methods) is logically consistent with the premises but lacks any discussion of implementation feasibility, performance cost, or how such checks could be realized without unduly constraining useful agent behavior; this directly affects the practicality of the recommended defense strategy.

    Authors: We agree that feasibility considerations are important for the recommendation to be useful. The argument for runtime checks follows directly from the dynamic character of the three structural sources, which cannot be fully resolved by static analysis or post-hoc review alone. In the revision we will expand the defense section with a high-level discussion of implementation directions, including lightweight runtime monitors, selective checking based on risk level, and mechanisms for source attribution. We will also address potential performance trade-offs and the need to avoid over-constraining agent autonomy. Detailed designs, cost measurements, and evaluations remain outside the scope of this position paper and are left for future technical work. revision: partial
