Every time a coding agent works through a task , reading files, running bash commands, calling tools, backtracking on a bad plan , it leaves behind a detailed log of that reasoning. Until now, those logs sat in a hidden folder on your machine and went nowhere. Factory and Hugging Face are changing that with a new integration that turns your Factory Droid session files into shareable, browsable datasets on the Hub.
What just shipped
You can now upload traces from agents like Claude Code, Codex, Pi, and Factory Droid directly to Hugging Face Datasets. The Hub auto-detects trace formats and tags your dataset as "Traces", with a dedicated viewer for browsing sessions, turns, tool calls, and model responses. The whole thing is zero-friction: these trace files are supported out of the box, so you can upload them without modifying or converting them first.
Here is where each agent stores its sessions locally:
| Agent | Local session directory |
|---|---|
| Claude Code | ~/.claude/projects |
| Codex | ~/.codex/sessions |
| Factory / Droid | ~/.factory/sessions |
| Pi | ~/.pi/agent/sessions |
Uploading is a two-command process using the Hugging Face CLI:
hf upload <username>/<dataset-name> ~/.factory/sessions . --repo-type dataset
# or keep it in sync as new sessions land:
hf buckets sync ~/.factory/sessions hf://buckets/<username>/<bucket-name>/factory
