Auditing Belief-Conditioned LLM Agents in Hidden-Information Social Deduction Games
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
In a controlled 9-player Werewolf environment with strict information isolation, the active-belief condition is associated with a large good-side outcome gain (0.205 to 0.390 on 200 seed-paired games) and fewer wrong witch poisons, but low direct action–belief consistency and camp-restricted results block attributing that gain to belief content. The paper’s central claim is therefore about method: an external belief layer used as an auditable cognitive baseline makes hidden-state LLM decisions measurable, diagnosable, and safer to iterate on under controlled comparison.
What carries the argument
External auditable belief layer: a per-agent role-probability state updated from structured events (factorized into base weight, evidence direction, and source credibility), compared against actual LLM actions as belief–action deviations, and fed into a defensive offline improvement loop that only proposes versioned strategy changes after batch review.
Load-bearing premise
The no-belief baseline still uses the same belief-oriented prompt scaffolding with only the belief content removed, so the win-rate gap may partly reflect prompt structure rather than the presence of usable belief information.
What would settle it
Run a native no-belief prompt (never designed around a belief section) and a shuffled-belief arm that keeps the belief formatting but destroys content; if the good-side win-rate gap versus active belief disappears under both controls, the association cannot be read as an effect of the active-belief condition.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper introduces an auditable evaluation framework for LLM agents in a 9-player Werewolf environment with code-level information isolation. An external belief layer (shadow or active) maintains role probabilities via factorized, hand-weighted logit updates; the system logs belief snapshots, belief–action deviations, and operational metrics, and supports a defensive offline improvement loop. Across 1,080 frozen games, a 200-seed paired A0/A1 comparison associates the active-belief condition with a higher good-side win rate (0.205→0.390; McNemar χ²=16.4, p<0.001) and fewer wrong witch poisons (22→4). The authors refuse causal attribution to belief content: exact action–belief consistency is ~0.21, camp-restricted arms do not follow a holder-benefit pattern, and A0 retains belief-oriented prompt structure with content removed. They position the contribution as the audit infrastructure itself—making effects measurable, rejecting forced consumption with evidence, and separating strategy from load confounds—and treat external belief primarily as an auditable cognitive baseline that also carries decision-relevant signal.
Significance. If the result holds under cleaner baselines, the work is a useful methodological contribution to multi-agent LLM evaluation: it treats trajectory-level auditability, information isolation, and operational confounds as first-class rather than engineering afterthoughts. Strengths include a large frozen corpus (1,080 games), seed-paired McNemar testing, zero LLM-error rates in the main arms, explicit load/concurrency controls, rejection of a failed forced-consumption intervention with evidence, and promised code plus archived trajectories. The careful refusal of causal claims about belief content is scientifically responsible. The paper is less a demonstration of improved hidden-role reasoning than a platform paper that makes such claims testable; that is still valuable for high-noise partially observable agent settings, provided the association is not oversold as decision-relevant signal from belief content.
major comments (3)
- §5.2 and §8.5–8.6: A0 is defined as a belief-content ablation that preserves the broader belief-oriented prompt structure rather than a natively designed no-belief prompt (A0-native is deferred). The abstract, §6.2, and conclusion still present the active-belief condition as associated with better good-side outcomes and as carrying “decision-relevant signal.” If residual scaffolding (belief-section formatting, residual subjective-signal instructions) already changes speech caution, vote thresholds, or poison restraint relative to ordinary LLM play, even the carefully worded association is not cleanly an effect of the active-belief condition versus standard agents. This is load-bearing for the paper’s positioning claim. Either run A0-native and/or a randomized/shuffled-belief arm (A-rand) as the authors themselves propose, or systematically reframe abstract/intro/conclusion so that the as
- §6.2–6.3 and Table 2: Camp-restricted arms (wolves-only good-side WR 0.313 > villagers-only 0.253) and low exact consistency (~0.21) already undermine a simple content-consumption account; the authors acknowledge this. The remaining claim that belief “also carries decision-relevant signal” is then under-supported by the same evidence used to reject holder-benefit. Aggregate top-1/top-2 hit rates are pooled across camps and action types and are inflated by werewolves who know teammates; good-side vote-time accuracy is only modestly above chance. Please either (i) report camp-separated, vote-time diagnostics with dynamic chance baselines as primary belief-quality metrics, or (ii) demote “decision-relevant signal” to a secondary, explicitly unresolved hypothesis and center the contribution strictly on auditability and measurable association under the stated ablation.
- §6.4 / Figure 8: The wrong-poison reduction (22/29 → 4/11; Fisher p=0.03) is presented as a concrete co-occurring behavioral change. Counts are small, Wilson intervals overlap substantially ([0.58,0.88] vs [0.15,0.65]), and poison is infrequent, so it cannot explain the aggregate win-rate shift. The manuscript already notes this, but abstract and §6.7 still list it alongside the main outcome as if it were a robust secondary finding. Tighten the abstract and summary so poison is clearly directional and exploratory, not a co-equal pillar of the empirical claim.
minor comments (6)
- §4.2, Eqs. (3)–(4): Factor values, clamp ranges, locked-state rules, and duplicate-evidence handling are deferred to the public release. For reviewability, include a short appendix table of the main w(e), d(e,r), and c defaults used in the frozen corpus.
- §4.4 / contribution 3: The harmful / justified / strategic deviation taxonomy is conceptual only; large-scale automatic classification is left to future work. State this limitation earlier (e.g., when deviations are first introduced) so readers do not expect quantitative validation in the present results.
- Table 2 and Figure 6: Smaller arms (n=80–150) are reported with wide CIs and without multiple-comparison correction. The text treats them as exploratory diagnostics; ensure figure captions and table notes say the same so they are not read as confirmatory.
- §5.4: All main results use a single model (deepseek-chat, T=0.6). A one-sentence caveat in the abstract or introduction that cross-model generality is untested would align the front matter with §8.5.
- References include several 2025–2026 arXiv items (e.g., WOLF, MINDGAMES, Hidden in Plain Text). Verify final citation status and venue at camera-ready time.
- Figure 1–5 are schematic and helpful; ensure vector versions and consistent terminology (e.g., “belief-disabled” vs “No-belief” in Figure 6) in the camera-ready.
Circularity Check
No circularity: empirical multi-agent evaluation against external game outcomes; belief is an engineered diagnostic, not a quantity defined to equal the reported win-rate association.
full rationale
The paper’s load-bearing claims are empirical associations measured against external, rule-engine outcomes (camp win/loss under fixed 9-player Werewolf rules; witch-poison correctness vs post-game ground-truth role maps; LLM-error/fallback/load rates). The active-belief vs belief-disabled A0/A1 comparison reports a seed-paired McNemar result on those external outcomes; the authors explicitly refuse to attribute the shift to belief content and leave mechanism unresolved. The factorized belief update (Δ = w·d·c, logit-space) is a hand-specified heuristic for auditability, not a fit to win rate or poison accuracy, and is not used as a “prediction” of those metrics by construction. There is no self-definitional loop, no fitted parameter renamed as prediction, no load-bearing self-citation uniqueness theorem, and no ansatz smuggled in via author-overlapping prior work. Concerns about A0 retaining belief-oriented prompt scaffolding are experimental-design / attribution issues, not circularity. The derivation chain is self-contained against external benchmarks.

- domain assumption Standard 9-player Werewolf rules (3 wolves, seer, witch, hunter, 3 villagers; night/day phases; stated win conditions) correctly define legal state transitions.
- domain assumption Code-level information isolation plus JSON serialization prevents agents from accessing ground-truth roles or other private observations at decision time.
- ad hoc to paper Factorized logit updates with hand weights are a Bayesian-inspired heuristic without optimality or calibration guarantees.
- domain assumption Final camp win rate and selected low-level errors (e.g., wrong poison) are meaningful diagnostic outcomes despite high variance.
- standard math Standard statistical tests (paired McNemar, Fisher exact, Wilson intervals) apply to the reported binary outcomes under the seed-paired design.

Evaluating LLM agents in hidden-information multi-agent settings is hard: final outcomes are high-variance and rarely reveal why an agent decided as it did. We study this in a 9-player Werewolf environment where agents act under strict, code-level information isolation, and we build an auditable framework that maintains an external belief state over hidden roles, logs belief updates and belief-action deviations as structured evidence, and supports a defensive offline improvement loop that reviews bad cases before any strategy change. Across 1,080 frozen games spanning belief-disabled, active-belief, kernel-ablation, camp-restricted, consumption-policy, and high-load arms, and including a seed-paired A0/A1 comparison, the active-belief condition is associated with substantially better good-side outcomes: in the 200-seed A0/A1 comparison the good-side win rate rises from 0.205 to 0.390 (paired McNemar $\chi^2 = 16.4$, $p < 0.001$), with fewer irreversible witch-poison errors. We do not, however, attribute this shift to belief content. Direct action-belief consistency is low ($\approx 0.21$), and giving belief only to the werewolves helps the good side more than giving it only to the good side, which argues against a simple holder-benefit account; we therefore report the effect as an association and treat its mechanism as unresolved. The contribution is the audit framework itself: it makes the effect measurable, exposes low direct action-belief consistency, rejects an unreliable forced-consumption intervention with evidence, and separates strategy effects from load confounds. We accordingly position external belief in high-noise hidden-information games primarily as an auditable cognitive baseline that also carries decision-relevant signal, turning opaque agent behavior into replayable evidence for safer, controlled iteration.
