The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
Aspects and the perception/action loop. An aspect is a policy-filtered view of the shared environment, generated by a p-agent for a specific stakeholder; it is the only information a group of working agents can perceive. Change requests are the only channel back to the environment: an a-agent summarizes the request, a p-agent decides whether it complies with policy, and if accepted the environment is modified and all aspects are regenerated. This loop—perception filters everything agents see, action passes through a policy gate—is what converts information security from a prompt-level instruction into an architectural boundary.
What would settle it
Run an adversarial test where the prompt to the p-agent that creates the General Public aspect instructs it to include the mortality rate, or where a change request embeds '100% mortality rate' inside innocuous update text; if the rate ever appears in the public aspect or a change summary, the zero-leak claim is refuted.
Extended reading notes
Core claim
The paper's central claim is that information leakage in agentic LLM systems can be eliminated by design: instead of giving every agent the whole document and asking it to behave, the environment is factored into stakeholder-specific aspects, each generated by a perception agent (p-agent) under explicit policy rules. Working agents inside an aspect never see the full environment; when they want a change, an action agent (a-agent) sends a change request back to the environment, the corresponding p-agent filters and applies it, and all p-agents regenerate their aspects. In the reported experiments this selective-disclosure architecture produced zero leakage across 30 runs and three adversarial
Load-bearing premise
The zero-leak guarantee assumes the p-agents (LLMs that generate each stakeholder's view) always filter prohibited content correctly, both when the view is first created and after every environment update; the tests only attack the action-agent asking for information, never the p-agent that builds the view or a change request that smuggles secret text inside a legitimate update.
Editorial extensions
If this is right
- In the paper's 30-run tests, the A2AI system never revealed the secret mortality rate under three deceptive prompts, while the typical AutoGen architecture leaked 37%–83% of the time depending on the prompt.
- Dynamic changes (incubation period 7→10 days) originating from the Medical Personnel aspect propagated correctly through the environment to all aspects, with only appropriate aspects showing the update.
- The same change requested from the General Public aspect was consistently rejected, showing policy enforcement is architectural rather than dependent on agent goodwill.
- Because no agent ever has access to the full environment, information that should stay within one stakeholder group is physically absent from other agents' contexts.
Reading between the lines
- The security result would likely weaken if an attacker targeted the aspect-generation p-agent directly or planted secret text inside a benign-looking change request; the paper acknowledges indirect prompt injection as a residual risk.
- Applied to organizational document workflows (contracts, policy updates, multi-party reports), the same separation principle could produce an audit-friendly change log, since every change is routed through a summarizing a-agent and a filtering p-agent.
- A natural quantitative extension would compare token/compute cost between aspect-limited agents and full-context agents on a larger corpus; the authors expect efficiency gains but do not measure them.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper proposes Aspective Agentic AI (A2AI), a framework in which LLM-based agents are situated in a shared environment but perceive only stakeholder-specific 'aspects' of it. Local p-agents generate each aspect from the full environment according to policy rules, and a-agents operate only within their aspect, pushing change requests back to the environment. The core empirical claims are: (1) against three deceptive prompts, A2AI leaks 'no inappropriate information' across 30 runs, whereas a native AutoGen baseline leaks up to 83% of the time, and (2) a change to the incubation period originating from the Medical Personnel aspect propagates correctly while the same request from the General Public aspect is refused, consistently across all runs. The paper frames these results as evidence that A2AI is 'secure by design' and 'enables zero information leakage.'
Significance. The conceptual contribution is real and well motivated. Separating information access at the architectural level, rather than relying only on prompt instructions, is an important direction for secure agentic AI, and the use of Umwelt-inspired aspects provides a clear vocabulary for selective disclosure. The implementation is transparent: the prompts are fully specified in Table 1, the task is well-defined, and the paper does not fit parameters or perform curve fitting. The comparison with a native AutoGen architecture is useful as an illustration, though not as a general benchmark. However, the headline claim of 'zero information leakage' is not established by the experiments: the tests only attack the a-agent inside an already-generated aspect, never the p-agent that creates the aspect, even though the p-agent is the component that actually reads the full classified environment. The dynamic-update result is also supported mainly by illustrative quotes rather than quantitative evidence. The framework is promising and worth revising, but the current empirical support is too narrow for the paper's strongest claims.
major comments (4)
- [Abstract; Implementation, Table 1; Discussion] The zero-leak claim is not supported because the p-agent boundary is never attacked. In Table 1, the p-agent 'aspect generation' prompt gives the LLM the entire classified environment text and asks it to reframe that content for a stakeholder. The experiment then questions only the a-agent inside an already-generated Public aspect, which has no secret in its context. Under those conditions, zero leakage from the a-agent is an expected consequence of a clean aspect, not evidence that the architecture prevents leakage. If the p-agent ever places prohibited content into the Public aspect—through imperfect redaction, prompt drift, or indirect prompt injection—the a-agent will see the secret and the zero-leak guarantee fails immediately. The paper's own Discussion concedes that 'indirect prompt injection, which remains a risk as with any LLM-based system' remains a threat. I ask that the clai
- [Design Principles, Principle 2; Implementation] The statement that 'no agent has access to all aspects' / 'no agent can perceive everything' is internally inconsistent with the implementation. The p-agents are themselves implemented as LLM agents (Table 1) and are explicitly given the full text of the environment. Thus, the privilege boundary is not between agents and the environment; it is between p-agents and a-agents. The manuscript should either classify p-agents as trusted infrastructure outside the agent model, or describe the p-agent as a privileged component that must itself be hardened. Without this clarification, the claimed architectural guarantee is overstated: the security of each aspect is entirely dependent on the reliability of a prompt-following LLM that has access to all secrets.
- [Illustration; Results Overview, Figure 4] The quantitative comparison lacks confidence intervals and statistical detail. The text reports that A2AI maintained confidentiality 100% of the time and AutoGen maintained it 63%, 37%, and 17% for the three prompt types, but no counts, spread, or tests are given. For a claim of 'zero' leakage, the absence of false negatives in the leak detector is also material: the paper states that 'we check if the agent's reply contains the information ... using an LLM to detect it,' but the detector itself is not validated. Since the target phrase '100% mortality rate' is a fixed string, deterministic matching or a documented validation of the LLM detector would make the result much more robust. Please provide per-run tables, confidence intervals, and a validated detection procedure.
- [Illustration, Experiment 2; Results Overview] The dynamic-information-change evaluation is essentially anecdotal. For A2AI, the paper quotes one successful Medical Personnel response and one refusal from General Public and states 'This behavior was consistent for all runs,' but no quantitative breakdown is given for the 30 runs: how many had the environment updated correctly, how many had each aspect regenerated correctly, and how many had any leakage? For AutoGen, failures are described with phrases such as 'in some runs' and one example of a PublicAgent leak, but no counts are provided. Because dynamic propagation and selective disclosure under change is a central contribution, this evidence needs to be tabulated per run and per aspect.
minor comments (5)
- [Figure 4] The figure shows 'percentage confidentiality maintained' but has no error bars or sample-size annotation. Please add confidence intervals or at least state the exact number of runs per condition (n=30 is stated in the text, but it would be clearer on the figure).
- [Illustration, AutoGen Setup] The text uses both 'RoundRobinGroupChat' and 'SelectorGroupChat' for the baseline; the description should clarify which mechanism was used for which experiment, since the architecture in Figure 3 and the written text are not consistent at first reading.
- [Table 2] The 'General Public' aspect output and the 'Medical Personnel' aspect output are useful, but some rows are cut off with '[content cut to reduce space]'. For reproducibility and for the reader to verify that no prohibited content appears in the full outputs, the authors should include complete generated aspects or provide them in an appendix or external repository.
- [References] There are small typographical issues in the references: 'V on Uexküll' appears with a space and odd capitalization, and the Dennett entry is listed as 'Dennett, D. B., & Dennett, D. B.'; the second occurrence should be a normal author pair. These should be cleaned up.
- [Illustration, leak detection] The paper says a positive match occurs when the reply contains the information '100% mortality rate,' but Table 2 writes the phrase as 'Mortality rate 100 percent' in the environment. The detection criterion should be specified exactly (e.g., substring '100%', '100 percent', or semantic equivalence) to avoid ambiguous results.
Circularity Check
Partial by-construction circularity: the A2 arm's zero-leak result is entailed by the policy-defined aspect content; the AutoGen comparison and 30-run real-LLM implementation keep the central claim independently grounded.
-
self definitional
[Design Principle 2; Implementation (Table 1 p-agent prompt, Table 2 General Public policy); Illustration Experiment 1; Discussion]
"No information relating to medical details, mortality rates, government decisions, or use of military should be provided without expressly being marked as “for disclosure to general public” ... we question the a-agent within the “Public” aspect on what it knows, and see if it can be encouraged to reveal information found in the environment but not in its aspect."
The zero-leak result is entailed by the construction: the General Public aspect is policy-defined to exclude mortality details, and the a-agent's only input is that aspect (plus memory seeded from it), so '100% mortality rate' is absent from its context; a disclosure query cannot leak (short of LLM hallucination). The 0/30 outcome therefore checks p-agent redaction compliance, not a general zero-leak property. The paper concedes the mechanism: 'leaks are stopped because agents have zero access to inappropriate information.' The vulnerable boundary — the p-agent, prompted with the full classified text ('Here is the text for you to reframe: ```{text}```') — is never attacked in Experiment 1, and the Discussion admits 'indirect prompt injection, which remains a risk as with any LLM-based syst
full rationale
The paper fits no parameters and derives no law; its central claim is an empirical comparison of two LLM agent architectures. The AutoGen arm's leak rates (37–83%) are measured and give the claim independent content, as does the 30-run real-LLM implementation showing the p-agent actually filtered the secret in every run. The circular component is confined to the A2 arm: because the General Public aspect is constructed under a policy that excludes mortality details and the a-agent receives only that aspect, the zero-leak outcome is in part a restatement of the design ('no access means no leak'), which the paper itself states in the Discussion. This is a transparent, acknowledged reduction rather than a hidden one, but it lowers the evidentiary value of the headline zero. The abstract overstates by dropping the paper's own caveat that indirect prompt injection 'remains a risk as with any LLM-based system' — and at the p-agent boundary the full classified text is in the prompt — which is a correctness risk rather than a circularity. Self-citations (Bentley et al. 2024; Lim & Bentley 2012; Lim et al. 2024) are background motivation, not load-bearing for the security claim; no uniqueness theorem or ansatz is imported from prior work. Net: one partial by-construction reduction in the A2 experimental arm, central comparative claim still independently grounded — score 4.
Assumptions & free parameters
assumptions (3)
- ad hoc to paper LLM p-agents will generate aspects that faithfully enforce the policy rules (no prohibited content included) and will re-generate aspects correctly after environment changes.
- domain assumption Agents have no information channel other than their aspect and the p-agent/a-agent update loop; a malicious user cannot query other aspects or the environment directly.
- domain assumption The AutoGen baseline represents a 'typical architecture' in common use, with no supplementary access-control code.

Agentic LLM AI agents are often little more than autonomous chatbots: actors following scripts, often controlled by an unreliable director. This work introduces a bottom-up framework that situates AI agents in their environment, with all behaviors triggered by changes in their environments. It introduces the notion of aspects, similar to the idea of umwelt, where sets of agents perceive their environment differently to each other, enabling clearer control of information. We provide an illustrative implementation and show that compared to a typical architecture, which leaks up to 83% of the time, aspective agentic AI enables zero information leakage. We anticipate that this concept of specialist agents working efficiently in their own information niches can provide improvements to both security and efficiency.
