TOON Dataset v0.4 — 1M Engineering Knowledge Records
A structured engineering knowledge dataset for training autonomous coding models. Each record (EKR) captures an engineering episode with reasoning chains, decisions, tradeoffs, and evidence.
Data Format
This dataset is available in two formats:
1. Parquet (recommended for ML)
dataset_1m.parquet— 279 MB- 28 flat columns, loadable via
datasetslibrary - List fields (reasoning, decisions, etc.) serialized as JSON strings
2. TOON (native format)
dataset_1m.toon— 2.54 GB- Structured indented format preserving full hierarchy
- Requires TOON parser for loading
Quick Start
from datasets import load_dataset
ds = load_dataset("Manthanbro1/Coding", split="train")
print(ds[0]["reasoning"]) # JSON string of reasoning steps
