# DebugTraj-50K: Developer Debugging Trajectory Dataset

50,000 debugging sessions with 665,364 step-by-step behavioral events across 8 programming languages and 71 error types.

## Load in one line

```python
import pandas as pd
sessions = pd.read_csv("hf://datasets/pyofpython/debugtraj-50k/code_debugging_sessions_fixed.csv")
events   = pd.read_csv("hf://datasets/pyofpython/debugtraj-50k/code_debugging_events_fixed.csv")
```

## What makes this unique

Most bug datasets only say "bug was fixed in 23 minutes."
This dataset records every step taken during those 23 minutes — every compile, edit, search, test, and commit.

## Files

| File | Rows | Description |
|------|------|-------------|
| code_debugging_sessions_fixed.csv | 50,000 | Session features (38 columns) |
| code_debugging_events_fixed.csv | 665,364 | Event trajectories (9 columns) |
| DATA_DICTIONARY_updated.md | — | Full column documentation |

## Use cases

- Predict debugging time from early session features
- Classify whether a session will succeed or be abandoned
- Next-action prediction for AI coding assistants
- Study junior vs senior developer behavior patterns
