ResearchRubrics: A Benchmark of Prompts and Rubrics For Evaluating Deep Research Agents (2511.07685v1)
Abstract: Deep Research (DR) is an emerging agent application that leverages LLMs to address open-ended queries. It requires the integration of several capabilities, including multi-step reasoning, cross-document synthesis, and the generation of evidence-backed, long-form answers. Evaluating DR remains challenging because responses are lengthy and diverse, admit many valid solutions, and often depend on dynamic information sources. We introduce ResearchRubrics, a standardized benchmark for DR built with over 2,800+ hours of human labor that pairs realistic, domain-diverse prompts with 2,500+ expert-written, fine-grained rubrics to assess factual grounding, reasoning soundness, and clarity. We also propose a new complexity framework for categorizing DR tasks along three axes: conceptual breadth, logical nesting, and exploration. In addition, we develop human and model-based evaluation protocols that measure rubric adherence for DR agents. We evaluate several state-of-the-art DR systems and find that even leading agents like Gemini's DR and OpenAI's DR achieve under 68% average compliance with our rubrics, primarily due to missed implicit context and inadequate reasoning about retrieved information. Our results highlight the need for robust, scalable assessment of deep research capabilities, to which end we release ResearchRubrics(including all prompts, rubrics, and evaluation code) to facilitate progress toward well-justified research assistants.
Summary
- The paper introduces a benchmark using 101 expert-curated prompts and granular rubrics spanning nine diverse domains.
- It employs a triple-review process and multi-axis criteria to assess deep research agents on complex, multi-step research tasks.
- Results reveal architecture-driven limits, notably in implicit reasoning and synthesis, with top agents scoring below 70% compliance.
ResearchRubrics: Framework and Benchmarking for Deep Research Agent Evaluation
Introduction
The increasing deployment of Deep Research (DR) agents—LLM-driven systems designed for multi-step, cross-document, evidence-based exploration and synthesis—necessitates rigorous evaluation approaches tailored to the complexity and diversity inherent in open-ended research tasks. "ResearchRubrics: A Benchmark of Prompts and Rubrics For Evaluating Deep Research Agents" introduces a comprehensive evaluation suite grounded in domain-diverse, expert-authored prompts paired with granular rubrics, systematically addressing the limitations of prior benchmarks.
Figure 1: Overview of ResearchRubrics and its evaluation pipeline.
Benchmark Design and Data Collection
ResearchRubrics comprises 101 single-turn research prompts spanning nine domains such as AI/ML, technical documentation, business research, creative writing, and historical analysis. Each prompt is annotated with a set of 20–43 expert-crafted rubric criteria, totaling 2,593 unique items. The data curation protocol employs a triple-review system where prompt and rubric drafts generated by Expert 1 undergo iterative refinement by Expert 2, followed by final adjudication by Expert 3. This ensures clarity, validity, and coverage of realistic research challenges.
Figure 2: The three-stage pipeline for creating and refining prompts and rubrics. An initial draft by Expert 1 is iteratively improved with Expert 2 before a final review and adjustment by Expert 3.
Prompt selection emphasizes both breadth (coverage across academic and everyday topics) and depth (encouraging multi-step, ambiguous, or multi-perspective reasoning). Prompts are systematically categorized according to a tri-axial complexity framework: conceptual breadth, logical nesting depth, and exploration (degree of underspecification or ambiguity).
Figure 3: Distribution of task complexity dimensions in ResearchRubrics.
Rubric Structure and Evaluation Criteria
Rubric criteria are divided into six axes: explicit requirements, implicit requirements, synthesis of information, use of references, communication quality, and instruction following. Each axis comprises mandatory (core, critically weighted) and optional (supplementary, lower-weighted) criteria. Positive weights reward strong response characteristics; negative weights penalize detrimental failure modes. All weights are mapped to a calibrated human preference scale, enabling atomic-level assessment and reducing reward hacking through overlap metrics.
This multi-axial rubric system addresses the prevalent weaknesses of relying on static answer keys or coarse, auto-generated metrics, enabling detection of nuanced capability gaps such as omission of unstated but essential context or deficient synthesis across information sources.
Automated Evaluation Protocols
ResearchRubrics utilizes an LLM-as-a-judge evaluation paradigm, employing state-of-the-art LLMs (GPT-5, Claude-Sonnet-4.5, Gemini-2.5-Pro) to grade agent responses against all rubric criteria. Binary (met/not-met) and ternary (fully/partially/not satisfied) grading schemes are supported, with the final compliance score computed as a weighted, normalized sum over rubric criteria. The scoring framework aligns with human expert judgment via Macro agreement analysis and ablation studies isolating the impact of rubric specificity and example inclusion.
Experimental Results
Evaluation across Gemini DR, OpenAI DR, and Perplexity DR demonstrates that no existing system exceeds 70% overall rubric compliance when measured with ternary grading. Gemini DR leads at 67.7%, with Perplexity DR trailing near 56% (ternary). Explicit factual retrieval and communication quality show low failure rates (<20%), while implicit reasoning and synthesis criteria account for nearly half of all failures, robustly across domains and agent architectures.
Figure 4: Rubric-axis failure rates across Deep Research agents. Dark bars represent ternary grading; light bars show binary grading. Implicit reasoning and synthesis show markedly higher failure rates compared to communication quality and references. The pattern holds across all three systems, indicating architectural rather than implementation limitations.
Further stratification by complexity dimension reveals monotonic degradation in compliance with increasing logical nesting; multi-step inference and planning exposes severe weaknesses with substantial drops even for top models.
Figure 5: Performance across Conceptual Breadth, Logical Nesting, and Exploration (Ternary Evaluation).
Mandatory criteria failures dominate in explicit and synthesis axes, while optional criteria failures constitute the majority in implicit reasoning—indicating that DR agents meet base requirements but miss finer quality determinants pivotal in high-stakes research settings.
Figure 6: Failure rate stratification by criterion importance. Mandatory criteria show systematically higher failure rates across most dimensions, with the notable exception of implicit reasoning, where optional criteria failures dominate. This inversion suggests implicit requirements primarily distinguish excellent from merely sufficient responses. Dark bars represent ternary grading; light bars show binary grading.
Length–Quality Relationship and Coverage Analysis
Agents display moderate positive correlation () between response length and compliance score, confirming that increased output verbosity generally accompanies higher rubric adherence. However, shorter outputs from Perplexity DR show reduced coverage, highlighting a persistent trade-off between information density and precision.

Benchmark-wide, most DR tasks require coverage across 4–5 rubric axes, enforcing balanced capability rather than single-axis optimization.
Figure 8: How many evaluation axes does each task cover? Distribution of the number of rubric axes per prompt. Most tasks require 4 to 5 distinct dimensions of quality simultaneously, encouraging balanced capabilities rather than single-axis optimization.
Automated Judge Alignment and Rubric Design Impacts
Macro scores for human-LLM judge alignment reach 0.72–0.76 under binary grading, demonstrating substantial feasibility for scalable automated evaluation of ResearchRubrics’s thousands of criteria. Notably, augmentation of rubrics via LLM-generated elaborations degrades alignment by 15–20 percentage points, whereas inclusion of concise, concrete examples improves agreement by 3–4%. This validates the necessity of expert curation and specificity in rubric construction, refuting assumptions about verbosity enhancing clarity.
Practical and Theoretical Implications
The systematic failures in implicit reasoning, cross-document synthesis, and deep task planning reflect fundamental architectural bottlenecks in DR agents, implicating model design rather than implementation or prompt engineering as the principal frontier for progress. Model optimization objectives cannot simultaneously achieve comprehensive coverage and high precision due to inherent trade-offs. The findings suggest branching directions for DR agent research, including integration of memory-augmented architectures, explicit world models, and hybrid retrieval-generation pipelines capable of persistent context management and meta-reasoning.
The benchmark's multi-axis, granular rubric coverage establishes a lower bound for robust DR agent deployment: systems must satisfy all mandatory criteria to reach sufficiency in high-value settings, with incremental progress measured via optional criteria compliance.
Future Directions
Benchmark expansion may focus on longitudinal, multi-turn research tasks and dynamic information retrieval reflecting live updates. Advances in agent architecture, particularly towards meta-cognitive or self-correcting reasoning modules, are necessary to surmount current synthesis and inference limitations. Automatized, scalable evaluation frameworks exemplified by ResearchRubrics are poised for adaptation to other domains requiring high-fidelity, long-form, open-ended exploration.
Conclusion
ResearchRubrics provides a rigorous, multi-dimensional framework for evaluating Deep Research agents, grounded in expert-created tasks and fine-grained rubric criteria. Empirical results reveal persistent, architecture-driven limitation in current agent capabilities, especially in implicit reasoning and synthesis. The findings delineate clear benchmarks for future agent development and underline the need for architectural innovation. The public release of ResearchRubrics, inclusive of prompts, rubrics, and evaluation code, offers the research community a high-fidelity resource to advance the state of AI-based research assistants.

What this paper is about (big picture)
This paper is about testing “Deep Research” AI systems—tools that use LLMs to browse, read, and combine information from many places on the web to answer big, open-ended questions. These questions don’t have one short, obvious answer and often need careful reasoning, checking facts, and writing long explanations.
The authors built ResearchRubrics, a new way to fairly grade these AI systems. It includes real-world questions plus detailed checklists (rubrics) written by humans that say what a good answer must include. Then they used both people and strong AI models to grade the AI systems according to these rubrics.
What the paper is trying to figure out
- Can we create a reliable, human-quality way to judge deep, open-ended research answers from AI systems?
- What makes some research questions harder than others?
- How well do today’s best Deep Research AIs actually do on realistic tasks?
- Can AI “judges” grade answers in a way that matches human graders?
- What makes a good rubric (grading checklist) clear and fair?
How they did it (in simple terms)
Think of a teacher who gives students a research project and a detailed checklist for grading. The authors do something similar, but for AI:
- They collected 101 real-style research prompts across nine areas (like business planning, history, consumer decisions, and technical topics).
- For each prompt, human experts wrote a careful rubric with 20–43 specific items (2,593 total items). These items check things like:
- Explicit requirements: Did you answer the question as asked?
- Implicit requirements: Did you include important things people expect, even if not asked?
- Synthesis: Did you connect ideas from multiple sources, not just list facts?
- References: Did you cite evidence that truly supports your claims?
- Communication: Is it clear and well organized for the reader?
- Instruction following: Did you follow the directions (format, tone, limits)?
- Some rubric items are mandatory (must-have) and others are optional (nice-to-have). Items also have weights (big points or small points), and there are negative items that subtract points for mistakes like false facts.
- They introduced a simple “three-level” grading for each item: satisfied (full credit), partially satisfied (half credit), or not satisfied (no credit). That’s like getting full, half, or zero points on a question.
- They also created a way to label how hard a task is, along three axes:
- Conceptual breadth: How many different topics you must cover.
- Logical nesting depth: How many reasoning steps are needed (one step vs. a chain of steps).
- Exploration: How open-ended or underspecified the task is.
- They tested popular Deep Research systems (from big AI companies) and had strong LLMs act as “AI judges” to grade the answers, then compared those grades with human graders to see how closely they match.
What they found and why it matters
- Overall performance is far from perfect:
- Even the best systems scored under 70% on the rubrics (about 68% at best with partial credit; about 62% with strict grading).
- Where AIs struggle most:
- Implicit reasoning: They often miss important context that isn’t spelled out.
- Synthesis: They have trouble weaving information from multiple sources into one coherent argument.
- Deep reasoning chains: Performance drops as the number of dependent steps grows (multi-step thinking is hard).
- Length helps a bit—but not just because it’s longer:
- Longer answers tended to score somewhat higher, likely because they cover more of the checklist, not simply because they’re wordy.
- References show a trade-off:
- Some systems include many citations but make more mistakes in them; others include fewer citations but are more accurate. Balancing coverage and precision is hard.
- Human vs. AI judge agreement:
- With strict (yes/no) grading, AI judges matched humans fairly well (around 0.72–0.76 Macro F1), which is good enough to make large-scale automated grading practical.
- With partial credit (full/half/none), agreement dropped, because “partial” introduces more gray areas.
- What makes a good rubric:
- Adding short, concrete examples to each rubric item improved agreement between human and AI judges.
- Letting an AI “rewrite” or “expand” rubric items made grading worse—human-written, concise criteria worked best.
Why this matters: Without a strong, fair way to grade deep research answers, it’s hard to improve these systems or trust them. ResearchRubrics provides a clearer path to measure progress and pinpoint weaknesses.
What this could change going forward
- Better training targets: Developers can see exactly where their systems fail (for example, missing implicit context or weak multi-document synthesis) and train models to fix those gaps.
- Safer, more reliable AI assistants: By focusing on mandatory criteria and factual grounding, future systems can avoid serious mistakes while still improving their overall quality.
- Smarter evaluations at scale: Because AI judges can align well with humans (especially with clear rubrics), researchers can evaluate many answers quickly and still keep quality high.
- Improved rubric design: Short, human-crafted criteria with examples will likely become standard, while auto-generated rubric text should be used cautiously.
- A shared benchmark for progress: Since the authors released the prompts, rubrics, and code, other teams can compare fairly and push the field forward.
In short, the paper builds a clear, human-centered way to grade deep research answers, shows where today’s systems fall short, and offers practical tools and tips to help the next generation of AI research assistants become more trustworthy and useful.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a concise list of concrete gaps the paper leaves unresolved and actionable questions for future research:
- Multi-turn evaluation: The benchmark uses single-turn prompts; it does not assess interactive, iterative deep-research workflows (clarifying questions, scoping, replanning over multiple turns).
- Process evaluation: Scoring focuses on final reports, not the research process (planning quality, exploration strategies, retrieval paths, stopping criteria, tool selection, and decision logs).
- Provenance and evidence linkage: There is no process-level evaluation of source provenance (e.g., stepwise evidence chains, claim-to-citation alignment, or counterfactual support) beyond coarse citation accuracy counts.
- Citation verification rigor: Methods for verifying that cited sources specifically support claims (not just being relevant) are under-specified; automated claim-evidence consistency checking is missing.
- Time-bounded truth and freshness: The benchmark does not control for temporal drift in “live” or current-event tasks; no time-bounded ground truth or freshness-aware scoring protocol is provided.
- Length–quality confounding: The authors observe a positive correlation between output length and scores but do not isolate causality; controlled studies holding information content constant are needed.
- Partial credit design: Ternary grading shows lower human–LLM agreement than binary, but it remains unclear how to design stable partial-credit scales (criterion-specific partial weights, continuous scoring, or anchors) that increase discriminative power without ambiguity.
- Weight calibration and reliability: Criterion weights are expert-assigned; there is no inter-rater reliability, sensitivity analysis, or psychometric validation (e.g., IRT) to test stability of weights and their impact on rankings.
- Mandatory vs. optional criteria: The practical threshold for “sufficient” responses (all mandatory met) versus overall quality remains uncalibrated; guidance for deployment thresholds and risk trade-offs is missing.
- Negative criteria semantics: The judge treats “negative criteria satisfied” as a penalty, which may be confusing for automated graders; the paper does not test whether judges reliably detect and correctly interpret such failure conditions.
- Score normalization and comparability: Normalizing by positive weights only may yield cross-task comparability issues (especially with different counts of optional/negative criteria); no analysis of score invariance across rubric lengths and weight distributions.
- Statistical rigor: Results lack confidence intervals, per-task variance, and significance tests for model comparisons; stability of rankings under re-sampling or judge changes is unknown.
- Judge reliability and bias: LLM-as-judge uses closed, proprietary models; cross-judge consistency, susceptibility to prompt phrasing, adversarial responses, and potential training contamination are not systematically stress-tested.
- Human–human agreement baseline: The paper reports human–LLM agreement but does not establish a human–human ceiling on rubric judgments to contextualize the achievable upper bound for automated judges.
- Complexity labeling validity: The triplet (breadth, depth, exploration) is expert-annotated with no inter-annotator reliability, operationalization protocol, or automatic labeling method; construct validity and predictive validity need evaluation.
- Domain expertise depth: “Experts” are STEM-generalists; the benchmark may under-capture nuances in high-stakes or highly specialized domains (e.g., clinical, legal, finance). Impact of involving domain specialists is not measured.
- Coverage and scale: With 101 tasks and nine domains, coverage of real-world deep research breadth (languages, cultures, regulatory contexts, long-horizon projects) remains limited; scaling guidelines and sampling strategy justification are absent.
- Multilingual and multimodal gaps: Tasks are English-only and text-centric; evaluation of multilingual agents, cross-lingual research, or multimodal evidence (figures, tables, PDFs with complex layouts) is missing.
- Tool-use and environment realism: The benchmark evaluates final outputs rather than the agent’s interaction with tools (browsers, APIs, spreadsheets); no metrics for tool efficacy, action quality, or efficiency (time, steps, compute).
- Robustness to gaming: Fine-grained, public rubrics may incentivize rubric gaming; no anti-gaming tests (e.g., vacuous verbosity, check-listing without synthesis, adversarial formatting) or stealth rubrics are explored.
- Safety and ethics: While negative criteria penalize disallowed content, the benchmark lacks explicit safety/ethics stress-tests (harmful advice, biased sourcing, equity considerations) and domain-specific harm assessments.
- Generalization and contamination: Using proprietary DR systems and judges raises replicability risks; potential data leakage after benchmark release and strategies for ongoing contamination mitigation are not addressed.
- Rubric augmentation and examples: Although LLM-augmented rubrics degrade agreement, the paper does not explore hybrid strategies (expert-written rubrics with verified micro-examples, counter-examples, or adversarial “gotchas”) that might improve clarity without semantic drift.
- Alternative evaluation paradigms: The paper does not compare rubric-based scoring to complementary methods (pairwise human preference judgments, automated fact-checking, retrieval grounding scores, or passage-level entailment).
- Personalized objectives: Exploration tasks often require eliciting user preferences; the benchmark does not measure how well agents identify missing constraints or align outputs to individualized goals.
- Release artifacts and reproducibility: It is unclear whether all human judgments, annotation guidelines, and judge prompts are released to enable exact replication of scoring pipelines and alignment analyses.
- Ethical review of rubric design: The social and normative assumptions embedded in “implicit requirements” and “communication quality” are not audited for demographic or cultural bias; fairness of rubric expectations is unexamined.

- Fine-grained rubrics: Detailed, specific evaluation criteria that allow nuanced assessment of answers. "We introduce outcome-based, fine-grained rubrics that provide rigorous evaluation of long-form research answers and closely align with expert judgments."
- Human–LLM judge alignment: The degree of agreement between human evaluators and LLM-based judges. "Human-LLM Judge Alignment for Auto-Evaluation"
- Implicit Requirements: Criteria covering expected but unstated aspects that a good answer should include. "Implicit Requirements"
- Instruction Following: Adherence to explicit user constraints or format requirements specified in the prompt. "Instruction Following"
- Length-quality conflation hypothesis: The idea that longer outputs may be judged as higher quality due to covering more criteria, not inherent superiority. "This supports the length-quality conflation hypothesis: longer reports often perform better because they cover more rubric criteria, not necessarily because evaluators prefer verbosity."
- LLM augmentation: Using a LLM to expand or rephrase rubric text in hopes of improving clarity. "LLM Augmentation evaluates whether prompting a LLM to automatically expand or rephrase rubric text adds clarity."
- LLM-as-judge: An evaluation paradigm where a LLM serves as the grader against rubric criteria. "Following the LLM-as-judge paradigm, we use powerful LLMs to assess rubric compliance"
- LLM-generated reference reports: Reference outputs produced by LLMs that are then used as the basis for evaluation, potentially introducing circularity. "evaluation metrics reliant on LLM-generated reference reports"
- LLM-generated rubrics: Rubrics produced automatically by LLMs rather than by human experts. "some benchmarks introduce LLM-generated rubrics and evaluation metrics reliant upon LLM-generated reference reports"
- Logical Nesting Depth: A complexity dimension capturing the number of dependent reasoning steps or hierarchical planning required. "We categorize each ResearchRubrics task along three orthogonal complexity dimensions: Conceptual Breadth, Logical Nesting Depth, and Exploration"
- Macro F1 score: The unweighted average of per-class F1 scores, used to measure agreement across multiple classes. "Macro scores between human annotators and automated evaluation across grading schemes and judge models."
- Mandatory criteria: Essential requirements that must be satisfied for an answer to be considered adequate. "Mandatory criteria define the minimum requirements for a valid response"
- Multi-document synthesis: Combining evidence from multiple retrieved sources into a unified, justified answer. "room for improvement in multi-document synthesis and rigorous justification."
- Multi-hop reasoning: Reasoning that requires chaining multiple dependent steps to arrive at an answer. "Multi-hop reasoning studies~\citep{yang-etal-2018-hotpotqa} demonstrate that while agents achieve 80%+ success on first-hop inference, bridge entity resolution in early neural layers creates hard limits on subsequent reasoning depth."
- Negative criteria: Rubric items designed to penalize undesirable behaviors such as inaccuracies or irrelevance. "included negative criteria targeting likely pitfalls"
- Negative rubrics: Evaluation checks that explicitly deduct points for incorrect, extraneous, or disallowed content. "The benchmarks also include negative rubrics that specifically aim to penalize extraneous or incorrect content."
- Optional criteria: Non-essential attributes that improve quality but are not required for sufficiency. "Optional criteria capture desirable but non-essential qualities"
- Partial credit: Awarding intermediate credit when a criterion is only partly met. "The shift from ternary to binary evaluation increases agreement by approximately 20 percentage points, confirming that partial credit introduces ambiguity without improving discriminative power."
- Reference overlap metrics: Evaluation measures based on the overlap between a model’s output and a reference text, often too coarse for nuanced tasks. "and simplistic reference overlap metrics."
- Rubric compliance: The extent to which an output satisfies the specified rubric criteria. "The results show that even the strongest agents fall below 68\% average rubric compliance"
- Rubric-based benchmark: A benchmark that evaluates outputs against a detailed set of rubric criteria rather than a single answer key. "ResearchRubrics is a rubric-based benchmark: each prompt is judged against a tailored set of criteria that define the requirements of a good answer."
- Semantic drift: Unintended changes in meaning introduced during rewriting or augmentation. "Human-authored concise rubrics with targeted examples outperform machine-generated verbose descriptions, likely because augmentation introduces semantic drift and emphasis distortion."
- Synthesis of Information: A rubric dimension assessing whether information is integrated across sources rather than merely listed. "across six dimensions: Explicit Requirements, Implicit Reasoning, Synthesis of Information, References, Communication Quality, and Instruction Following."
- Ternary grading: A scoring scheme with three levels (e.g., satisfied, partially satisfied, not satisfied) enabling partial credit. "We propose a ternary grading scheme for a rubrics-based benchmark that supports partial credit assignment"
- Ternary indicator: The three-valued marker returned by the judge for each criterion (1, 0.5, 0). "m_{r_i} is the ternary indicator returned from the model-based judge"
