Agent Traces on the Hub

You can now upload traces from your agents (Claude Code, Codex, Pi) 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.

No preprocessing needed, just upload the JSONL files from your local session directories as-is:

Agent	Local session directory
Claude Code	`~/.claude/projects`
Codex	`~/.codex/sessions`
Pi	`~/.pi/agent/sessions`

Useful for sharing debugging workflows, benchmarking agent behavior across models, or building training data from real coding sessions.
