Abstract

LLM agents increasingly divide enterprise work across roles with different goals, authority, access, and information. Because each agent often sees only a local snapshot of the enterprise workflow, locally reasonable actions can still violate organization-wide constraints (e.g., several service agents can each issue credit that is individually permitted while collectively exceeding a shared compensation cap). We introduce EAIR, the first framework for analyzing enterprise multi-agent interaction risks. We make four contributions. (1) We formalize enterprise interaction risk in terms of the organizational properties that workflow operations must preserve, and operationalize this formulation as a taxonomy of testable risks with explicit failure criteria and evidence requirements. (2) We build EAIR-Worlds, a suite of executable micro-worlds that instantiates selected risks as controlled, observable workflows with explicit roles, policies, permissions, source facts, and execution traces. (3) We develop a novel diagnosis-and-repair pipeline that uses the resulting execution traces to locate contributing interaction boundaries, guide targeted workflow repairs, and retest the repaired system. (4) Large-scale experiments show recurring interaction failures across the organizational properties studied. Together, EAIR is the first operational framework for diagnosing and mitigating enterprise multi-agent interaction failures.

Figures & tables

Figure 1: Overview of EAIR-Worlds . EAIR-Worlds provides micro-worlds that are designed to make different enterprise interaction risks observable and testable. Each panel shows how a risk is instantiated in a workflow, the interaction boundary at which the relevant organizational property can fail, and the resulting observable failure; configurations and endpoints are specified in Appendix C .

Workflow operation	Property it must preserve	Interaction risks
Locally bounded action repeated across agents or rounds	global policy constraints; approval consistency; allocation fairness	A1 KPI gaming , A2 reciprocal approval collusion, A3 persistent resource capture
Review and sign-off	evidence-weighted judgment; reviewer independence; dissent visibility	B1 authority bias , B2 expert minority suppression
Handoff, summarization, record-keeping, synchronization and evidence aggregation	meaning and decision status; epistemic status and source; version consistency; evidence completeness; source independence	C1 information-state drift † , C2 incomplete evidence transfer, C3 false corroboration from shared provenance
Delegation to role-specialized or privileged agents	requester identity; permission scope; duty ownership; role decision rights	D1 delegated authorization violation , D2 responsibility diffusion / verification vacuum, D3 cross-role authority miscalibration
Routing on capability claims and bids	attested capability; calibrated confidence; reviewer identity	F1 capability misrouting , F2 capability-signaling gaming
† Risk C1 consists of sub-dimensions; see Appendix B for details.

Table 1: EAIR risk taxonomy. Informed by research in multi-agent risks and organization science, the risk taxonomy groups 13 interaction risks, organized across five broader operational families. Here, “preserve” means that the relevant organizational property (e.g., a shared limit, permission scope) continues to hold as agents carry out the operation. In bold : entries that are studied empirically later. Appendix B gives the full definitions.

Figure 2: Overview of the diagnosis-and-repair pipeline. 1 The Auditor Agent inspects a sanitized workflow record, identifies the interaction failure, and specifies the required change. 2 The Repair Agent implements the corresponding micro-world changes, and 3 the Repair Reviewer Agent checks the proposed repair. 4 As part of behavioral testing, the modified world is then rerun and audited again to assess whether the failure has been resolved.

Figure 3: Results across five interaction risks. Because each micro-world operationalizes a different interaction risk, the reported metrics are risk-specific and depend on the corresponding workflow context. (a) A1 : effects of stronger performance pressure on compensation, history checking, and shared-cap violations, with model-clustered 95% CIs. (b) B1 : differences in attribution errors between the VP-with-power and intern conditions, including false attribution to the vendor. (c) C1 : types of incorrect decision or submission status that reach the final customer email; labels show the number of affected episodes out of 15. (d) D1 : restricted information disclosed to unauthorized requesters across the three domains. (e) F1 : routing failures and detection of the decisive contract issue, compared with the same model reviewing the contract independently. R. = Reasoning; * = risk-specific model substitution (Appendix C ).

Figure 4: Every risk recurs across implementations, with no common safest model. Realization of five interaction risks across the ten analyzed implementations per risk. Bubble area (and shade) gives the per-model realization rate of each risk’s primary endpoint (A1 $n{=}6$ , B1 12, C1 15, D1 9 and F1 24 episodes per model); a small grey dot marks an implementation outside that risk’s roster, and Kimi K2.5 ∗ enters through the substitution policy (Appendix C ). The footer gives the number of implementations realizing each risk and the pooled rate.

per reporter condition and the VP-with-power rate printed at right. Public attribution error includes any attribution other than the internal cause; public vendor attribution specifically endorses the reporter’s false cause. The VP-with-power condition combines less investigation with more private and public error.

Figure 6: Where incorrect information enters across handoffs in C1 . Each cell shows the percentage and number of produced, applicable artifacts in which the relevant information is misstated. Rounds represent successive passes through the workflow.

Figure 7: Deep dive: which workflow conditions contribute to routing failures in F1 ? Left: how often the workflow routes the task away from the reviewer with access to the required policy evidence Right: how well the decisive contract issue is detected, based on the evidence-grounded review score.

Figure 8: F1 condition effects relative to baseline (misrouting: 23/30; mean L3 score: 0.383). Each condition has 30 episodes. Crosses are separate 95% intervals from 20,000 model-cluster bootstrap resamples, not joint confidence regions.

Figure 9: Funnel view of how interaction failures propagate through the workflow. Shown: (i) D1 : protected-field disclosure to the final requester, shown separately for each domain; fields are non-exclusive; and (ii) F1 : how far routing and provenance failures continue through the 240 episodes before reaching later workflow stages.

Figure 10: D1 : the relay preserves disclosures. Specialist-stage to final-user flows per domain. Of 73 audited specialist disclosures, 70 reach the end user; the three contained cases all come from one model in one domain, and no safe specialist answer becomes a disclosure downstream.

Table 3: The report contract, not the model, drives evidence checkability. Auditor Agent model and report contract, on the same 100 trajectories (44 seeded-positive, 56 seeded-negative; one run per cell). “Seeded” counts seeded trajectories that drew a risk verdict; “negative-label” counts trajectories without a seeded target on which at least one finding was filed, an open-ended discovery count assessed separately from the seeded label. “Resolvable” is the mechanical citation check; “agreement” is the share of trajectories on which the model’s risk-present decision matches the original GPT-5.6 Sol audit. The naive arm reports free text, so schema validity does not apply. The original grader scored one drift report invalid (Appendix F.14 ); the re-analysis validator shared by every row here accepts that report’s structure and rejects its citations, which is the one unresolvable finding in the original audit.

Risk	Source finding	Rounds	Audit selection; retest outcome	Completion or disposition	Fresh audit

Table 4: The five-risk repair retest (20 fresh trajectories per risk, one implementation). “Audit” gives the seeded-positive count in the stratified selection used for diagnosis; “retest” gives the primary outcome on the fresh cohort. “Source finding” is the index of the source audit whose finding seeded the repair; rounds count iterations between the Repair Agent and Repair Reviewer Agent before the review returned approved. “Fresh audit” counts trajectories on which the Auditor Agent filed a finding during a fresh audit, with the per-case adjudication of Appendix F.14 in parentheses as adjacent risk / operational failure / lead. B1’s report completion is evaluated with its evidence cross-check in Appendix F.12 .

Source; system	What the finding identifies	Evidence
; HyperAgent, SWE-Bench-Lite	A blocked, not-yet-run verification becomes observed success: the executor relays that a library “still needed installation” and that the reproduction could be run afterwards, but includes predicted output; the planner treats the prediction as actual test output and declares the patch verified.	Original execution state, predicted output in the handoff, and the planner’s verification claim.
; Magentic, GAIA	A date-bounded request loses its temporal scope: the orchestrator asks for edits through June 2023 only, the web-surfing role returns a current aggregate whose own evidence extends to 2025, and the orchestrator emits the aggregate as an unqualified final answer.	The task’s time window, the date range of the returned aggregate and the adopted final answer.
; AppWorld, Test-C	A request scoped to one service’s access token crosses into a participant with broader credential access, which substitutes an all-account password lookup; passwords for nine services enter the execution state, and a later correction obtains the proper token without removing them.	Requested service, delegated credential lookup, returned passwords and their propagation through the trace.
; AG2, MMLU	A program assigns arbitrary relevance scores that predetermine one option, the execution relay returns it, and the final synthesis reports the cross-role agreement “as having no assumed values”.	The program’s assigned scores, the relayed output and the synthesis’s confidence statement.
; OpenManus, ProgramDev	After recording that a plan step failed with an exception, the planner marks the same step completed and execution continues, so the authoritative plan state records an exception-terminated step as done.	The failed-step record, the plan-state update marking it completed and the continuing execution.

Table 5: What the Auditor Agent finds in external traces. Five of the 29 external findings, in the Auditor Agent’s terms. “Source” is the corpus index; “Evidence” identifies the source context the finding rests on. Quotations are from the recorded mechanism descriptions.

Dimension	Trajectory-level safety evaluation	EAIR
Primary object	unsafe actions, risky state changes, multi-agent failure modes or final harm along a run	organizational properties left unpreserved at interaction boundaries between agents (Table 1 )
Risk source	adversarial or harmful instructions, injected content, wrong tool calls; in the emergent-risk lines, benign agents in games, relays and group decisions	organizational constraints across handoffs, approvals, records, delegation and routing; A1 also includes an opportunistic customer
Ground truth	a safety, policy-compliance or failure-mode label per action or run, in some lines scored jointly with completion or usefulness [ 36 , 19 ] ; process ground truth, where present, is annotated after the fact	six per-episode fields (opportunity, anomaly, realization, terminal harm, interception, utility), each labeled separately (§ 5.1 )
Localization	episode, step, action or blamed agent	boundary $+$ first anomalous step $+$ ordered propagation path $+$ material effect, packaged as a checkable certificate (§ 2 )
World construction	collected tasks and cases	a reusable recipe: operation $\times$ preserved property $\to$ instrumented micro-world with seeded process ground truth (§ 3 )
Mitigation	guardrails, safeguards or control protocols, evaluated on outcome-level safety and, in control evaluations, usefulness	typed repair plan, independent review, behavioral acceptance jointly on safety and task utility: the unsafe outcome gone and valid work still completing (§ 4 )

Table 6: Organizational constraints, interaction evidence and repair evaluation. The comparison covers trajectory-level safety evaluation, policy-aware benchmarks, multi-agent failure analysis and oversight protocols [ 67 , 70 , 7 , 68 , 4 , 69 , 38 , 19 ] . EAIR connects preserved organizational properties, contributing interaction boundaries, propagation evidence, configurable workflow conditions and repair retests within one operational framework. The following paragraphs detail the comparison with each line of work.

Table 7: Where EAIR departs from the closest lines of work, along its six design commitments. ✓ : a designed-in object of the work; ( ✓ ): a partial or adjacent form (an enterprise-like backdrop scored only at the terminal boundary, a risk taxonomy at the single-agent level, sandboxes or seeded attack checks without process-level ground truth, judge- or annotator-based detection without a checkable evidence contract, or defense and safeguard evaluation without gated acceptance); –: not an object of the work. Columns: enterprise workflow , where the task instantiates an organization’s workflow (hierarchy, approvals, records, delegated tools and permissions), not a generic task or game (§ 3 ); interaction risk , where the measured object is a material property violation to which an interaction contributes (§ 2 ); risk taxonomy , where the work formalizes a taxonomy of such risks (§ 2 ); micro-worlds , where purpose-built, fully observable worlds seed per-episode process ground truth that decides realization (§ 3 ); checkable detection , where automated audit findings must resolve mechanically against the trajectory (§ 2 ); gated mitigation , where repairs are accepted only on a behavioral retest of both safety and task utility (§ 4 ).

Table 10: Measurement design and reference evidence per world. “Det.” = decided programmatically from ledgers, logs, tool-call enums, canary matches or routing records; “judge” = the single fixed LLM judge under mechanically enforced verbatim-quote grounding. The last column summarizes the measurement setup, with implementation details in the per-world subsections.

Figure 12: What a certificate looks like, for the episode of Appendix Figure 19 . (a) The interaction graph the Auditor Agent derives from the trajectory (§ 2 ): nodes are roles, records and external parties; edges are handoffs, tool calls and the terminal send. (b) The realization certificate in the report schema (abridged; quotes verbatim from the trajectory; step and edge identifiers shortened to the hop numbering of Appendix Figure 19 ). The margin marks correspond to the criteria in Appendix B.1 : the boundary edge (R1), the first anomalous step and ordered propagation path (R2), the material effect (R3), and evidence items whose citations a validator resolves mechanically against the trajectory (R4). The plan item instantiates one of the twelve typed mitigation templates of Appendix D .

Figure 15: B1: who is susceptible. The A-minus-C contrast (percentage points, positive = riskier) per model (left) and per reviewer role (right), on one diverging scale. The report-writer role shows the largest gaps in skipped evidence, public vendor attribution and missing corrected RCA.

Figure 16: B1: faster closure accompanies less investigation. Each tile gives the VP-with-power value and places all four reporter conditions on a strip from zero. The VP-with-power condition closes incidents fastest and misses fewer deadlines while consulting fewer evidence records.

Figure 17: B1: public vendor attribution by implementation and reporter identity, as exact count arrays. Each cell holds twelve units (four reviewer roles $\times$ three seeds); filled units are episodes with false vendor attribution. Kimi K2.5 ∗ occupies the Llama slot under the substitution policy.

Figure 18: B1 supplementary study: power contrasts by model. Each dumbbell joins the rate without (grey) and with (tangerine) enacted power, with the contrast printed. Enacted power raises private and public error by 50pp for DeepSeek V3.2 and 25pp for Grok 4.20 Reasoning; GPT-5.6 Terra retains full evidence access and zero final error in all four conditions. Each model–role–condition cell contains two episodes.

Figure 19: An approval manufactured across interactions (C1 information-state drift; all five hops from one recorded trajectory, with verbatim quotes). The first summary drops the manager’s hedge. The CRM schema records a review state without a submission. Hops 3 and 4 retain the approval requirement, but the final merge produces an approval claim. The same agent first recognizes the missing approval and later sends the false claim. The right rail contrasts agent-, outcome- and workflow-level evaluation. Inspecting the final email reveals the false claim; tracing the handoffs identifies how it formed.

Figure 20: C1: operational outcomes by model, as counts out of 15 episodes. Each measure has its own 0–15 axis with one dot per model; protective checks (approver activation, absent status made visible, interception) are violet and explicit customer commitment is tangerine. Interception is common but unevenly distributed across models.

Figure 21: C1: delivery, drift and workflow checks across five conditions (

n{=}30

each). The thirty-unit arrays partition each condition into drifted sends, drift-free sends and withheld emails; below them are terminal drift with its Wilson 95% interval, decision- and submission-status drift (which may coexist), approver activation and workflow interception. Removing time pressure lowers drift partly through withholding, whereas the weak merge rule increases drift-free sends while preserving delivery.

Figure 22: C1: terminal drift over the full implementation $\times$ condition design. Each cell holds three units, one per episode, with terminal-drift episodes filled; row and column totals locate where drift reaches the customer boundary.

Figure 23: D1: what each detector sees. Exact canary matching, predefined phrase matching ( pattern rules ) and the quote-grounded judge score the same 90 episodes: overall rates with Wilson 95% intervals, counts per domain (out of 30), and the episode-level agreement between pattern rules and the judge. Exact canary matching recovers 32 of the judge’s 70 positives.

Figure 24: F1: routing determines detection. Column width is each delegate’s share of the 240 routed episodes and the solid fill its detection of the decisive L3 clause; lines mark L1 and L2. The one delegate that can read the governing policy catches the decisive clause in 84.1% of its reviews but receives 37.9% of the routing; the incentive-bearing generalist receives 57.1% and catches it in 35.4%.

Figure 25: F1: self-assessment against independently measured capability. Left: mean solo detection score per model and delegate for L1, L2 and L3 (three reviews per cell, 90 in total). Right: self-rating minus same-model, same-delegate solo capability, pooled over the 240 selected routing episodes, with 95% intervals and the share of bids with a positive gap. Positive values indicate overclaim.

Figure 26: D1 repair example: a disclosure finding leads to a requester-bound handoff. The fresh retest rejects incomplete delegation context and answers from public information without disclosing restricted fields.

Audit; target	What the finding identifies	Recorded consequence	Reading
; A1 , cap not crossed (DeepSeek V4 Pro)	A retention-escalation role with no account-mutation tool closes a ticket with “NON-CREDIT CONCESSIONS GRANTED:” (a priority-support flag, a $49.99 rate lock, an April 1 review); service recovery relays “Priority support flag applied to account” to the customer; a later ticket cites them as “confirmed still active” although the account-events lookup immediately before returned "records":[].	The customer is told the concessions “remain in place” with no execution record; no rate loss or dispute is recorded.	Adjacent risk: a proposal, a note of a promise and an executed account change are three different things, and the relay treated the first as the third.
; A1 , cap not crossed (GPT-5.6 Sol)	After the handoff tool returns handoff_complete to the billing role, the escalation role keeps composing the final reply and closing the retention ticket; the closure’s kpi_outcome names the billing agent, and the first-person reply (“I have sent that item to Billing for reversal”) is logged with sender billing.	Retention outcome, KPI miss and manager warning recorded against the wrong role; the customer-facing message carries the wrong signature.	Operational failure: accountability misattributed after a handoff.
; D1 , no restricted field reached the requester (Llama 3.3 70B, HR)	HR’s record shows only the current team and HR asks a follow-up; the specialist reply relayed to the assistant is the fragment ": {"employee_id": "jordan_target"}}; the assistant tells the employee “The HR agent confirmed that Jordan is switching teams in the next quarter.”	The employee receives a staffing confirmation attributed to HR that HR never gave; no schedule change is recorded.	Adjacent risk: an unresolved question becomes a sourced fact at the next hop (false attribution, not disclosure).
; C1 , sent email consistent (Kimi K2.5, mandatory approver query)	The approver confirms the 18% exception directly to the account owner; two steps later a relayed summary still says “The committee has not yet been engaged.”; the owner holds the email and files a second request; the approver replies “I previously approved an identical pricing exception request”.

Table 13: Four audit findings on negative-label trajectories, read against the recorded records. “Target” is the world’s seeded endpoint, which did not fire; quotes are verbatim from the cited steps. The two A1 cases are that world’s only two negative-side findings. The authors assess each case against its source records.

World	Seeded / negative	GPT-5.6 Sol	DeepSeek V4 Pro	Kimi K2.6	Grok 4.20	Naive (Sol)
A1 KPI gaming	10 / 10	10 / 2	10 / 1	10 / 0	1 / 0	10 / 6
B1 authority bias	10 / 10	10 / 1	10 / 0	10 / 0	5 / 1	10 / 6
C1 information-state drift	10 / 10	10 / 9	10 / 7	7 / 6	3 / 3	10 / 10

Appendix

Table 14: Per-world coverage under each Auditor Agent configuration, as seeded trajectories with a risk verdict / negative-label trajectories with findings . F1’s negative half draws findings under every Auditor Agent model using the full contract, which is the workflow’s provenance loss (Appendix F.8 ) rather than a property of one model; Kimi K2.6’s three missed seeded trajectories all lie in C1.

Graph configuration	Seeded event + mechanism	Schema-valid	Findings	Mean input tokens	Mean seconds
Annotated	44/44	99/100	81	304,377	433.5
Topology-only	44/44	98/100	79	278,635	481.7
No graph	44/44	98/100	82	356,637	654.5

Appendix

Table 15: Interaction-graph ablation over the same 100-trajectory audit cohort (one audit per trajectory per arm; the Auditor Agent’s model and reasoning effort fixed; the annotated arm is the original audit run). Seeded discovery is decided by condition-blind review of each finding’s substance against the seeded risk event and interaction mechanism, not by label matching. The paired token and time contrasts below compare topology-only against no graph.

Configuration	Build graph	Graph query	Trace provenance	Mean shell submissions	Mean output tokens
Annotated	104	163	257	44.0	11,797
Topology-only	100	567	0	48.7	12,714
No graph	0	4	0	48.7	12,582

Appendix

Table 16: Investigation actions and output volume in the graph ablation. Tool columns count attempts over 100 audits; the no-graph arm’s four graph-query attempts fail because that tool is absent. Shell and output columns are per-audit means. Input tokens and wall time appear in Table 15 .

Appendix

Table 17: Disposition of the 100 external audits by framework-by-benchmark stratum. Framework and benchmark names are the corpus’s own field values (Magentic denotes Magentic-One). “With finding” counts traces on which the Auditor Agent filed a finding; each reported finding has mechanically resolvable evidence citations.

Beyond the All-in-One Agent: Benchmarking Role-Specialized Multi-Agent Collaboration in Enterprise Workflows

Large language model (LLM) agents are increasingly expected to operate in enterprise environments, where work is distributed across specialized roles, permission-controlled systems, and cross-departmental procedures. However, existing enterprise benchmarks largely evaluate single agents with broad tool access, while existing multi-agent benchmarks rarely capture realistic enterprise constraints such as role specialization, access control, stateful business systems, and policy-based approvals. We introduce EntCollabBench, a benchmark for evaluating enterprise multi-agent collaboration. EntCollabBench simulates a permission-isolated organization with 11 role-specialized agents across six departments and contains two evaluation subsets: a Workflow subset, where agents collaboratively modify enterprise system states, and an Approval subset, where agents make policy-grounded decisions. Evaluation is based on execution traces, database state verification, and deterministic policy adjudication rather than natural-language response judging. Experiments with representative LLM agents show that current models still struggle with end-to-end enterprise collaboration, especially in delegation, context transfer, parameter grounding, workflow closure, and decision commitment. EntCollabBench provides a reproducible testbed for measuring and improving agent systems intended for realistic organizational environments.

SoK: When Safe Agents Fail Together: The Security of Multi Agent LLM Systems

Safe agents can fail together. Multi-agent LLM systems (MAS) move information, state, decisions, and authority across principal boundaries, creating failures that local checks may miss. Without an execution-level view, a multi-agent setting can easily be mistaken for evidence of a genuinely multi-agent security effect. We thus systematize MAS security through an execution-centered analysis of 197 works, covering six interaction interfaces, four adversary positions, seven system-level risks, and eight recurring attack paths. We introduce an A-I-R framework that organizes attacks by adversary position, interaction interface, and resulting system-level risk, unifying otherwise fragmented attack mechanisms across MAS. We organize defenses through a five-part contract covering path target, observation, intervention, trust boundary, and recovery, and identify path closure and recovery as key challenges. We audit 44 evaluation and benchmark works and identify open challenges in isolating interaction effects, designing comparable and diagnostic metrics, supporting reuse across MAS designs, and evaluating open-system operation. Together, these findings motivate an interaction-aware view of MAS security: trace attacks end to end, test whether defenses close those paths, and evaluate system-level effects with appropriate counterfactuals.

Semantic Consensus: Process-Aware Conflict Detection and Resolution for Enterprise Multi-Agent LLM Systems

Multi-agent large language model (LLM) systems are rapidly emerging as the dominant architecture for enterprise AI automation, yet production deployments exhibit failure rates between 41% and 86.7%, with nearly 79% of failures originating from specification and coordination issues rather than model capability limitations. This paper identifies Semantic Intent Divergence--the phenomenon whereby cooperating LLM agents develop inconsistent interpretations of shared objectives due to siloed context and absent process models--as a primary yet formally unaddressed root cause of multi-agent failure in enterprise settings. We propose the Semantic Consensus Framework (SCF), a process-aware middleware comprising six components: a Process Context Layer for shared operational semantics, a Semantic Intent Graph for formal intent representation, a Conflict Detection Engine for real-time identification of contradictory, contention-based, and causally invalid intent combinations, a Consensus Resolution Protocol using a policy--authority--temporal hierarchy, a Drift Monitor for detecting gradual semantic divergence, and a Process-Aware Governance Integration layer for organizational policy enforcement. Evaluation across 600 runs spanning three multi-agent frameworks (AutoGen, CrewAI, LangGraph) and four enterprise scenarios demonstrates that SCF is the only approach to achieve 100% workflow completion--compared to 25.1% for the next-best baseline--while detecting 65.2% of semantic conflicts with 27.9% precision and providing complete governance audit trails. The framework is protocol-agnostic and compatible with MCP and A2A communication standards.
