Paper2Rebuttal: A Multi-Agent Framework for Transparent Author Response Assistance
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The paper's central discovery is that the bottleneck in automated rebuttal writing is not fluency but the organization of decisions and evidence. RebuttalAgent enforces a verify-then-write workflow in which reviewer comments are atomized into discrete concerns, a query-conditioned hybrid context combines compressed manuscript summaries with high-fidelity excerpts, an on-demand search module assembles citation-ready external evidence briefs, and a strategist agent produces an explicit plan with to-do items and commitment checks before any final text is drafted. The paper reports that this pipeline outperforms strong direct-to-text baselines under matched base models, with the largest gains in
What carries the argument
The central mechanism is the multi-agent 'verify-then-write' pipeline: an extractor atomizes reviews into atomic concerns with coverage checks; a parser and compressor turn the manuscript into a paragraph-indexed compressed representation with fidelity checks; evidence construction builds a concern-conditioned hybrid context (compressed text plus verbatim passages) and, on demand, external literature briefs; a strategist generates an inspectable response plan separating interpretative defense from necessary intervention; checkers verify coverage, evidence linkage, and cross-point consistency; and a drafter realizes the validated plan, rendering unrun experiments as explicit placeholders.
Load-bearing premise
The headline outperformance claim rests on a rubric-based LLM judge as a proxy for rebuttal effectiveness; the real reviewer follow-up signals collected in the benchmark are used only to select papers, not to score responses, so if the judge rewards the agent's structured format rather than the substance of the argument, the central claim collapses.
What would settle it
Take the benchmark's positive and negative reviewer follow-up labels as the outcome instead of the LLM-judge scores, or have human experts score rebuttals with the structured formatting hidden. If RebuttalAgent no longer beats the direct-to-text baselines in either condition, the outperformance claim is an artifact of the judge or the format.
If this is right
- Every argument in a rebuttal can be traced to a specific passage in the manuscript or a specific external reference, making the draft auditable before submission.
- Concerns that demand new experiments are turned into action items with placeholders, so the model cannot silently fabricate results.
- Authors can intervene at an inspectable plan stage and retain final control over strategy and wording rather than editing opaque generated prose.
- Because the gains are larger for weaker base models, structured scaffolding can partly substitute for raw model capability in high-stakes writing tasks.
- The ablation result that external evidence briefs are the most critical artifact implies that citation-ready literature synthesis deserves priority in similar systems.
Where Pith is reading between the lines
- The same verify-then-write decomposition could apply to other high-stakes response documents, such as grant rebuttals, ethics responses, or regulatory replies, where claims must be anchored and unrun work must be flagged; the paper does not test these.
- The benchmark already collects reviewer follow-up labels indicating whether concerns were resolved; using those labels as a direct outcome metric, instead of the rubric judge, would test whether the agent's format advantage translates into real reviewer satisfaction.
- A minimal variant that only adds the external-evidence briefs to a direct-to-text baseline might capture much of the observed gain, since ablations show that module drives the largest drops when removed.
- The structured plan itself could be reused as a checklist for human authors, even without automated drafting, turning the agent into a planning aid rather than a writer.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper proposes RebuttalAgent, a multi-agent framework that reframes rebuttal generation as an evidence-centric planning task. The pipeline decomposes reviews into atomic concerns, builds concern-conditioned hybrid contexts from compressed and raw manuscript text, optionally retrieves external references, generates an inspectable response plan with checkers, and then drafts a formal rebuttal. The authors introduce RebuttalBench, derived from ICLR OpenReview threads, and evaluate RebuttalAgent and direct-to-text LLM baselines using a Gemini-3-Flash judge with a nine-component rubric. They report consistent gains in relevance, argumentation, and communication quality, with ablations indicating that evidence construction is the most critical module.
Significance. If the results held, the contribution would be meaningful: the system produces inspectable intermediate artifacts, distinguishes interpretive defense from required new experiments, and offers a benchmark with real reviewer follow-up signals. The matched-backbone comparison is a fair design, and the rubric is detailed. However, the central faithfulness claim is directly contradicted by the drafting prompt in Appendix D, which instructs the model to invent experimental values. Moreover, all headline results are single-point LLM-judge scores with no human validation, error bars, or significance tests, and the benchmark's own positive/negative follow-up labels are not used as the outcome metric. These issues make the current evidence insufficient for the paper's strong claims, although the architectural ideas remain worth developing.
major comments (3)
- [Appendix D, Prompt: Rebuttal Letter Writer; §3.3; §5.1] The final drafting prompt explicitly instructs the model: 'Since you are an AI and cannot perform actual experiments... you must invent plausible, realistic values/results that support the user's argument,' with an asterisk marker. This is the Drafter Agent in the main pipeline. Section 3.3 claims the system 'explicitly inhibits result generation' and renders missing experiments as '[TBD]' placeholders. Since Section 5.1 runs all main experiments in fully automated mode with no human intervention, the evaluated RebuttalAgent outputs can contain fabricated numerical results. The A2 Evidence Support rubric in Appendix D explicitly rewards 'new quantitative results,' so the judge may assign higher scores precisely for the hallucinated content that the paper claims to prevent. This is an internal inconsistency that directly undermines the strict faithfulness claim and contaminates the headli
- [§4.1, §4.2, §5.1, Table 1] RebuttalBench collects reviewer follow-up responses and uses them as a 'decisive classification signal' to label instances positive or negative, but these labels are never used as the outcome metric. All Table 1 results are scores from a single closed-source LLM judge, Gemini-3-Flash, with no human validation, no reported variance, and no significance tests. The rubric is authored by the same team, and the judge model is also one of the agent backbones. While a shared judge can be a reasonable comparison tool, the central claim that RebuttalAgent 'outperforms strong baselines in coverage, faithfulness, and strategic coherence' is currently supported only by an unvalidated proxy. The authors should report human agreement, error bars, significance tests, or validate the judge against the follow-up labels they collected.
- [§5.3, Table 2] The ablation results are quantitatively weak and partly contradictory to the narrative. Removing Checkers improves Coverage (+0.03) and Logic Consistency (+0.02); removing Input Structuring improves Statement Clarity (+0.05); most other deltas are within 0.1–0.3. Without error bars or significance tests, the text's claim that 'checkers also contribute measurably to overall quality' is unsupported. The conclusion that 'the gains of RebuttalAgent arise from the combination of complementary modules' overstates what Table 2 shows. Report confidence intervals or significance tests before drawing these conclusions.
minor comments (5)
- [§6, §3, §5.3] There are name inconsistencies: the conclusion calls the system 'RESPONSEAGENT,' the contributions section says 'REBUTTALGENT,' and Section 5.3 writes 'ebuttalAgent.' Use one consistent name throughout.
- [§4.1] The sentence 'we apply automatic filtering to retain instances with sufficiently explicit follow-up signals and discard ambiguous cases' appears twice nearly verbatim in the 'Filtering and corpus construction' paragraph.
- [References] Some references are incomplete or informal, e.g., 'xGr', 'goo', and a URL-style citation for 'Gemini Deep Research.' These need to be formatted consistently.
- [Appendix E, Case Study] A planned deliverable in the second case study says 'showing strong positive correlation (r >0.9)' as if it were a concrete result. Since this is a plan, it should be marked as a placeholder or target, otherwise it exemplifies the same invented-number problem at the planning stage.
- [§5.1, Abstract] The paper claims to be the 'first multi-agents framework' for rebuttal, but the related work already includes multi-agent simulations of peer review (e.g., AgentReview). The novelty claim should be softened to avoid overclaiming.
Circularity Check
RebuttalAgent's A2 'Evidence Support' gains are authored by the system's own drafter prompt: the judge rubric rewards new quantitative results, and the prompt commands the model to invent them.

fitted input called prediction
[Appendix D ('Prompt: Rebuttal Letter Writer') and Appendix D ('Prompt: Unified Rebuttal Evaluation', A2 Evidence Support); Sec. 3.3; Table 1]
"Since you are an AI and cannot perform actual experiments, but the rebuttal might require empirical evidence (e.g., ablation studies, baseline comparisons), you must invent plausible, realistic values/results that support the user's argument. ... MANDATORY RULE: Any time you generate a specific number, metric, or experimental result that is not present in the input, you MUST append a distinct asterisk symbol (*) right after it. ... A2 Evidence Support ... 5 Backed by new quantitative results, specific comparative data, or rigorous mathematical derivations presented directly in the rebuttal."
The drafter prompt instructs the model to fabricate the exact content the evaluation rubric rewards: new quantitative results and comparative data. RebuttalAgent therefore receives high A2 'Evidence Support' scores and the headline Argumentation Quality gains in Table 1 by construction, while the unmodified baselines are not given the 'invent' instruction. The paper claims in Sec. 3.3 that the system 'explicitly inhibits result generation' and renders missing experiments as [TBD], but the final-draft prompt does the opposite. Thus the 'faithfulness' improvement is not an independent measurement; it is a self-fulfilling product of the authors' own rubric and their own system prompt. The Appendix E plan even contains 'strong positive correlation (r >0.9)' as a deliverable, showing the patter
full rationale
The central circularity is the evidence-support metric: the authors design a judge rubric that awards top marks for 'new quantitative results' and simultaneously instruct their Drafter Agent to invent exactly such results, with an asterisk as a placeholder. Since main-paper experiments run the full system in automated mode (Sec. 5.1), the reported A2 gains and the 'faithfulness' claim are not validated against verifiable manuscript content; they are produced by the system's own instruction interacting with the authors' own rubric. This is a partial but real circularity: coverage, structure, and communication improvements may still be meaningful, but the headline claim of outperforming baselines in faithfulness and argumentation quality is confounded by construction. The benchmark's reviewer follow-up labels, described as a 'decisive classification signal' (Sec. 4.1), are used only to select papers rather than as outcomes, further weakening external anchoring, though that is a validity issue rather than a circular one. No load-bearing self-citation chain or ansatz-smuggling was found. Score 6.

read the original abstract
Writing effective rebuttals is a high-stakes task that demands more than linguistic fluency, as it requires precise alignment between reviewer intent and manuscript details. Current solutions typically treat this as a direct-to-text generation problem, suffering from hallucination, overlooked critiques, and a lack of verifiable grounding. To address these limitations, we introduce $\textbf{RebuttalAgent}$, the first multi-agents framework that reframes rebuttal generation as an evidence-centric planning task. Our system decomposes complex feedback into atomic concerns and dynamically constructs hybrid contexts by synthesizing compressed summaries with high-fidelity text while integrating an autonomous and on-demand external search module to resolve concerns requiring outside literature. By generating an inspectable response plan before drafting, $\textbf{RebuttalAgent}$ ensures that every argument is explicitly anchored in internal or external evidence. We validate our approach on the proposed $\textbf{RebuttalBench}$ and demonstrate that our pipeline outperforms strong baselines in coverage, faithfulness, and strategic coherence, offering a transparent and controllable assistant for the peer review process.
