Abstract

LLM-based agents are increasingly deployed with authority over consequential resources and decisions in real systems. These agents often operate alongside human and LLM-based participants who hold different forms of authority. Yet workflow roles, permission settings, and review mechanisms do not necessarily reflect the authority realized in practice. We introduce AuthorityLens, a framework for measuring a system's authority structure. Starting from an authority portfolio, we evaluate a system along three dimensions: what the system is authorized to do (System Authority), how much joint participation is required to exercise that authority (Authority Separation), and how much authority each participant holds (Principal Authority). We derive these measurements from the minimal combinations of participants sufficient to realize each outcome across admissible runtime states. We apply AuthorityLens to Codex, OpenCode, and Gemini CLI across 13 operating configurations over a common portfolio of agent operations. We find that nominal configurations do not map cleanly onto realized authority. In Codex, Full Access changes System Authority only marginally while substantially concentrating authority in the executing Assistant. OpenCode's Build and Plan configurations have the same System Authority and Authority Separation despite different workflows and root-level permissions. In Gemini CLI, model-based review increases Authority Separation without changing System Authority. Principal Authority further distinguishes authority replication from authority separation: spawned or delegated agents can become alternative holders of the same authority without increasing the required joint participation. Together, these results demonstrate that AuthorityLens provides a unified framework for measuring and comparing realized authority structures across agent systems.

Appendix

Panel of Figure 4 — Figure 4: Roadmap of Appendix A. Main-text objects and questions are mapped to their supporting appendix sections. Proposition 1 is supported by the finite representation theorem in A.5 , and Proposition 2 additionally by the within-class invariance condition in A.4 ; A.6 addresses complete pattern representation. The bottom routes give reading paths for these results. The control mechanisms in Section 5 are examined in Appendices C – E .

Product	Audited authority-bearing Principals	Authority-relevant execution structure
Codex	Assistant; User or Guardian reviewer; eligible spawned Assistants	Reviewed modes use a workspace sandbox and mediated execution; Full Access disables that sandbox profile; Guardian inspection executes under a separate read-only boundary
OpenCode	Build or Plan root; General; Explore; Build-child; Plan-child; User	Native read/edit, shell, planning, and Task delegation have distinct permission paths; Plan restricts ordinary native editing but retains shell execution
Gemini CLI	Assistant; Generalist; Investigator; CLI Help; User; optional Conseca Reviewer	Native read/search and validation-output routes remain available in Plan; shell availability and subsequent approval requirements depend on the operating configuration

Multi-agent LLM systems exchange messages before acting through tools, but message delivery, signing authority, and tool-side enforcement are separate trust boundaries. We represent them as communication, authorization, and execution structures, and use the authority cut to characterize the smallest independently compromised signer coalition that can construct a policy-valid false-claim proof under stated assumptions. Controlled paired hidden-state studies reveal four distinctions. First, no fixed-message routing contrast across four models meets the prespecified large-effect criterion; when relays rewrite messages, executed false-state action rates vary by model and route configuration. Second, presented source-identity cues do not uniformly increase protected-action selection across three models. Third, on invalid-proof cases, Nemotron and Llama request protected actions in 52.1% and 54.2% of trials, respectively, yet a deterministic tool gate commits none: request-level and commitment-level safety readouts diverge. Finally, a separate single-model authorization check shows that a false claim with a policy-valid compromised-signer proof can pass the gate, since proof validity is not factual truth. These findings motivate evaluating delivered information, qualified authorization, model proposals, and committed actions separately.
