DataClawEval
An executable benchmark for end-to-end data-engineering agents in industrial environments.
DataClawEval measures an autonomous agent's ability to inspect data, implement and debug pipelines, and materialize correct artifacts in realistic data-engineering workflows. It contains 100 production-grounded tasks across five execution engines: PySpark, MySQL, HiveSQL, PrestoSQL/Trino, and FlinkSQL. Each task runs in an isolated Docker sandbox and is evaluated by a case-specific, deterministic, rule-based grader.
What's Inside
- Production-grounded tasks — 100 end-to-end tasks reconstructed from production-grade implementations written by professional enterprise data engineers and validated through execution checks, expert perturbations, and expert review.
- Batch and streaming coverage — batch transformations in PySpark, MySQL, HiveSQL, and PrestoSQL/Trino, plus streaming-oriented FlinkSQL tasks involving event time, watermarks, windows, joins, and aggregations.
- End-to-end agent workflows — schema inspection, data exploration, implementation, execution, debugging, output validation, and artifact materialization.
- Artifact- and process-oriented grading — task-specific graders assess executable outputs and engineering behaviors such as exploration, execution efficiency, and self-verification.
- Reproducible environments — every run starts in a fresh container with task-specific data, services, execution engines, and deterministic initialization.
- Flexible agent integration — run evaluations with the
codebuddy,claude-code, orcodexbackend. The paper evaluates 16 model configurations through a unified CodeBuddy scaffold. - Batch experiments — evaluate one or more engines in parallel and generate combined reports.
Task Suite
| Execution engine | Workload | Tasks |
|---|---|---|
| PySpark | Batch (offline-compute) |
20 |
| MySQL | Batch (offline-compute) |
20 |
| HiveSQL | Batch (offline-compute) |
28 |
| PrestoSQL/Trino | Batch (offline-compute) |
12 |
| FlinkSQL | Streaming (online-compute) |
20 |
| Total | 100 |
The suite is also balanced between 50 English and 50 Chinese task prompts and covers five business domains: Ops & Resource Governance (30), Data Analytics & User Growth (30), Security & Risk Control (16), Content, Community & Dev-Efficiency (14), and Advertising & Marketing (10).
Each task lives in tasks/<workload>/<engine>/<task_id>/ and contains:
task.md— the natural-language request and metadata such as timeout and engineinit/— initialization or verification assets; batch tasks initialize tables here, while FlinkSQL tasks generally define generated streaming inputs in the submitted SQLgt/— the reference implementation and task-specificgrade.pyused during evaluation
How It Works
For every model–task run, the harness:
- Starts a fresh Docker container from the configured
DOCKER_IMAGE. - Starts the services required by the selected engine and initializes task-specific inputs.
- Prepares the agent workspace with the task prompt and engineering tools.
- Runs the selected agent backend and records its execution trajectory.
- Loads
gt/after agent execution and runs the task-specific grader in the same container. - Collects the submitted solution files, workspace snapshot, scores, usage data, and execution
transcript into
output/, then removes the container.
Requirements
| Component | Requirement |
|---|---|
| Docker | Docker CLI and a running daemon |
| Python | Python 3.11 on the host; the scripts invoke python3.11 |
| Storage | Enough free space for the multi-engine image and task outputs |
| Model access | Credentials and network access for the selected agent backend |
The evaluation image provides a ready-to-use multi-engine environment with Spark 3.5.0, Flink 1.18.1, Trino 435, MySQL, a Hive Metastore, Python 3.11.13, and the supported agent runtimes.
Quick Start
0. Verify prerequisites
Make sure Docker is installed and running, and that Python 3.11 is available.
docker version # verifies the Docker CLI and daemon connection
python3.11 --version # Python 3.11 is required
1. Install Python dependencies
python3.11 -m pip install -r requirements.txt
2. Get the evaluation image
You have two options.
Option A — Pull the prebuilt image (recommended)
Skip the local build and pull the ready-made image from the registry:
docker pull dicemy/dataclaweval:v1.0
docker tag dicemy/dataclaweval:v1.0 dataclaw-eval:v1.0 # match DOCKER_IMAGE in .env
The default
DOCKER_IMAGEin.envisdataclaw-eval:v1.0. Either retag the pulled image as shown above, or setDOCKER_IMAGE=dicemy/dataclaweval:v1.0in your.env.
Option B — Build locally
prepare.sh vendors the installed CodeBuddy Agent SDK and builds the
dataclaw-eval:v1.0 evaluation image.
bash script/prepare.sh
3. Configure credentials
Copy the example env file and fill in the values for the agent backend you plan to use.
cp .env.example .env
Then edit .env:
DOCKER_IMAGE=dataclaw-eval:v1.0
# CodeBuddy auth (required for the `codebuddy` harness)
CODEBUDDY_AUTH_TOKEN=
CODEBUDDY_API_KEY=
CODEBUDDY_INTERNET_ENVIRONMENT=ioa # public | internal | ioa
# OpenRouter (required for `claude-code` and `codex` harnesses)
OPENROUTER_API_KEY=
OPENROUTER_BASE_URL=https://openrouter.ai/api/v1
Get a CodeBuddy API key: overseas → https://www.codebuddy.ai/profile/keys · China → https://copilot.tencent.com/profile/ · iOA (Tencent staff) → https://tencent.sso.copilot.tencent.com/profile/keys. Set
CODEBUDDY_INTERNET_ENVIRONMENTto match your account type.
4. Run the evaluation
# Run a single execution engine
bash script/run_batch.sh -P # PySpark
bash script/run_batch.sh -M # MySQL
bash script/run_batch.sh -H # HiveSQL
bash script/run_batch.sh -F # FlinkSQL
bash script/run_batch.sh -PR # PrestoSQL/Trino
# Run workload groups
bash script/run_batch.sh -offline # PySpark + MySQL + HiveSQL + PrestoSQL/Trino
bash script/run_batch.sh -online # FlinkSQL
bash script/run_batch.sh -all # all 100 tasks
Use script/run_batch.sh -all to evaluate the complete 100-task suite. Results and a combined
report are written to output/.
Usage Reference
run_batch.sh options:
| Flag / Option | Description |
|---|---|

To run a single task directly (bypassing batch mode):
python3.11 eval/run_batch.py \
--agent-backend codebuddy \
--task tasks/offline-compute/PySpark/pyspark_001/task.md \
--model deepseek-v4-flash-ioa
Output & Scoring
Each run is saved under output/<harness>/<category>/<task_id>/<run_suffix>/ with the submitted
solution, workspace snapshot, transcript, usage statistics, and score.json.
DataClawEval evaluates both the final data product and the engineering workflow:
- Artifact quality — executability, schema correctness, row-level alignment, numerical accuracy, and categorical or business correctness.
- Process quality — exploration adequacy, execution efficiency, and self-verification.
The overall score combines both dimensions:
[ S = \alpha S_{artifact} + (1-\alpha)S_{process} ]
The artifact weight (\alpha) is configured per task, with 0.7 as the most common value. Repository
outputs normalize overall_score to 0–1, while the paper presents scores on a 0–100 scale.
Batch runs aggregate model and engine summaries into
output/experiment_report_<timestamp>.json and report the average score and the number of tasks
with overall_score >= 0.5:
Category/Model Tasks Avg Score Pass(>=0.5)
offline-compute/PySpark/model_a 20 0.7350 15/20
Paper Results
The paper evaluates 16 model configurations from eight families on all 100 tasks: 1,600 primary runs in total. Every model uses the same fixed Tencent CodeBuddy scaffold, and only the underlying LLM changes. The primary table uses one run per model–task pair; task prompts are evenly split between English and Chinese (50 each).

|---|---|---|
| GPT 5.5 | 74.9 | 299.8k |
| Claude Opus 4.8 | 74.3 | 318.3k |
| Claude Sonnet 5 | 73.8 | 457.9k |
| Gemini 3.1 Pro | 73.7 | 292.4k |
