Data-Agent and DataOps Evaluation Landscape — 2026

This synthesis is backed by primary source cards under `sources/21-benchmarks/`

This synthesis is backed by primary source cards under sources/21-benchmarks/ for AgenticDataBench, semantic metadata and agentic retrieval, LongDA, AgenticOpsEval, kRAIG, DataGovBench, DCA-Bench, Replayable Financial Agents, and FinReasoning.

Evidence Boundaries:

Sources are promoted at different confidence levels. DCA-Bench and FinReasoning have primary GitHub evidence inspected in this pass. AgenticOpsEval has a reachable public GitLab project shell but needs deeper file inspection. AgenticDataBench, semantic metadata, LongDA, kRAIG, and DataGovBench are arXiv-primary source cards until code/data artifacts are found and locally verified. Reported model scores remain source-reported snapshots unless a StateBench fixture reproduces the harness.

Executive Answer

The new sources change the eval map in one concrete way: agents should not be graded only on final answers or chat quality. Enterprise evals need a separate DataOps lane that scores whether the agent found executable data, understood metadata, navigated documentation, produced valid transformations, and grounded diagnostic reasoning in real evidence.

The expanded core:

Source What It Adds Hard Boundary
AgenticDataBench Broad data-agent tasks across 15 vertical domains, 5 fintech B2B use cases, skill-level data-science operations Abstract-only until code/data are inspected
Do Agents Need Semantic Metadata? FAIR-mapped retrieval eval showing structured metadata beats open-web retrieval for usable datasets LLM-judge caveat; not a full data-quality system
LongDA Long-document data analysis over surveys, codebooks, raw files, and publications General data-agent pattern, not finance-specific
AgenticOpsEval Microservice failure diagnosis with localization, identification, and evidence-grounded reasoning Diagnosis benchmark, not autonomous remediation authority
kRAIG Natural-language DataOps pipeline generation into Kubeflow Pipelines with clarification and validation Abstract-only until runnable code is verified
DataGovBench Data governance workflows with realistic noise, transformation code, and pipeline reliability scoring Abstract-only until code/data are verified
DCA-Bench Dataset quality issue discovery across online dataset platforms, with GitHub/HF artifacts and output schema LLM-evaluator and licensing/ethics caveats
Replayable Financial Agents Determinism, decision replay, faithfulness, and DataOps exception handling for tool-using agents GitHub artifact reported but not locally run

Research Map

These sources sit between RAG evals and coding-agent evals. They evaluate the middle work that most corporate agents actually perform:

find data
  -> verify metadata and access
  -> interpret schema/docs/codebooks
  -> clean/transform
  -> compute
  -> cite evidence
  -> diagnose failures
  -> produce auditable artifact

That means the eval harness must preserve more than a prompt and response. Minimum useful records include dataset URL, download URL, schema fields, license/access note, documentation spans, transformations, code execution logs, artifact hashes, evaluator labels, and final answer.

Source Findings

AgenticDataBench

AgenticDataBench expands the benchmark unit from “answer this question” to “execute a data-science workflow.” Its important design move is skill-level coverage: data tasks are organized around recurring operational patterns, with task-solution diversity selected by skill composition.

StateBench implication: a GitLab-runner eval should report per-skill performance for data discovery, schema inspection, cleaning, joining, aggregation, visualization, modeling, and artifact validation. A single aggregate score hides the failure.

Semantic Metadata for Agentic Data Retrieval

This paper names the failure our Samaya miss exposed: Last-Mile Utility. The agent can find a plausible page but not the machine-usable artifact. The paper reports that the semantic metadata path delivers higher precision for metadata-rich registries and machine-readable downloads, while open-web retrieval often returns prose pages or portal landing pages.

StateBench implication: source ingestion must distinguish:

  • page found;
  • canonical source found;
  • machine-readable artifact found;
  • schema/metadata found;
  • access/license recorded;
  • data is computationally usable.

Source card: sources/21-benchmarks/semantic-metadata-agentic-data-retrieval-raw.md.

LongDA

LongDA is the benchmark pattern for enterprise knowledge bases with attached datasets. It requires agents to read heterogeneous documentation before writing analysis code. This is the corporate data-estate reality: the answer depends on codebooks, schema notes, survey methods, raw files, and prior publications.

StateBench implication: knowledge-base evals should include documentation navigation and codebook-to-data alignment, not only answer faithfulness.

Source card: sources/21-benchmarks/longda-long-document-data-analysis-agents-raw.md.

AgenticOpsEval

AgenticOpsEval brings the same idea into operations. It scores localization, identification, and reason/evidence grounding over microservice failures. This is useful for DataOps because data pipelines fail through logs, metrics, runtime events, database/middleware issues, and application logic.

StateBench implication: operational evals need evidence-grounding labels on the reasoning trace. Final root-cause correctness is insufficient.

Source card: sources/21-benchmarks/agenticopseval-microservice-failure-diagnosis-raw.md.

kRAIG

kRAIG moves from evaluating analytical answers to evaluating generated DataOps pipelines. The key design pattern is ReQuesAct: the agent clarifies ambiguous intent before synthesizing a Kubeflow Pipeline, then validates pipeline integrity before execution.

StateBench implication: pipeline-generation evals should score clarification quality, KFP validity, extraction/loading success, transformation accuracy, and pre-execution validation separately.

Source card: sources/21-benchmarks/kraig-dataops-pipeline-generation-raw.md.

DataGovBench

DataGovBench frames governance as executable transformation under data quality, security, and compliance constraints. Its reversed-objective methodology synthesizes realistic noise, which is exactly the kind of controlled corruption enterprise data-quality evals need.

StateBench implication: add governance-specific tasks where the answer is not a paragraph but a corrected dataset or transformation pipeline with validation proof.

Source card: sources/21-benchmarks/datagovbench-data-governance-workflows-raw.md.

DCA-Bench

DCA-Bench is the most concrete data-quality artifact in this pass. It has a GitHub repo, Hugging Face dataset, task metadata, four hint levels, and a Curator output schema with issue, evidence, and description.

StateBench implication: source-ingestion evals should include hidden defect discovery. A good agent should identify incomplete documentation, inaccurate labels, licensing gaps, ethical/legal risks, and outdated information before those issues contaminate downstream retrieval, evals, or training data.

Source card: sources/21-benchmarks/dca-bench-dataset-curation-agents-raw.md.

Replayable Financial Agents

The replayability harness adds an audit metric often missing from eval design: the same inputs should produce repeatable decisions and evidence-aligned trajectories. The source also includes a DataOps exceptions lane, making it a bridge between finance governance and operational data failures.

StateBench implication: each GitLab-runner eval should record repeated-run variance, trace determinism, decision determinism, and faithfulness separately from accuracy.

Source card: sources/21-benchmarks/replayable-financial-agents-determinism-faithfulness-raw.md.

Failure Domains To Add

Failure Domain What To Classify Eval Evidence Needed
Data discoverability Could the agent find the right dataset, not just a page? dataset URL, registry metadata, search trace
Last-mile utility Did it reach a machine-readable file/API? download/API URL, file type, row count, schema
Metadata fidelity Did it preserve schema, units, time, entity keys, and license? schema fields, units, dates, access/license notes
Documentation alignment Did it use the right codebook or methodology note? cited doc span, variable mapping, method constraint
Transformation correctness Did cleaning/join/aggregation code match the task? code, execution log, intermediate artifact hash
Computation correctness Did output values reconcile? deterministic checker, tolerances, recomputation trace
Evidence-grounded diagnosis Did the reasoning cite the relevant logs/metrics/spans? trace/log refs, fault category, localization label
Remediation boundary Did the agent avoid unauthorized fixes? diagnosis vs action flag, approval state
Replay drift Does the same input produce the same trajectory and decision? repeated runs, trace hashes, decision hashes

Harness Implications

The current source-ingestion pipeline should add a DataOps artifact contract:

{
  "source_system": "web|hf|github|gitlab|registry|internal",
  "landing_page_url": "...",
  "machine_readable_artifact_urls": ["..."],
  "metadata_urls": ["..."],
  "schema_fields": ["..."],
  "row_count": 0,
  "license_or_access": "...",
  "documentation_refs": ["..."],
  "code_or_harness_refs": ["..."],
  "execution_required": true,
  "eval_dimensions": [
    "discoverability",
    "last_mile_utility",
    "metadata_fidelity",
    "documentation_alignment",
    "transformation_correctness",
    "computation_correctness",
    "evidence_grounding"
  ],
  "caveats": ["..."]
}

That contract is intentionally separate from training exports. The raw evidence must stay in source cards and trace artifacts; SFT or preference rows should be late exports after redaction, dedupe, rights review, and held-out split assignment.

Watchlist From This Pass

  • FinReasoning was promoted into the finance cluster because it is a financial research-report benchmark with concrete GitHub schema evidence.
  • Hugging Face search surfaced multiple low-evidence community finance/data mirrors. These should remain watchlist until primary org, code, license, schema, and reproducibility are verified.
  • AgenticDataBench claims an open-sourced testbed, but this pass did not verify a concrete repository. Treat it as abstract-level evidence until found.
