Upload traces from AI agents (Claude Code, Codex, Pi) directly to Hugging Face Datasets. The Hub auto-detects trace formats and tags datasets as Traces with a dedicated viewer for browsing sessions, turns, tool calls, and model responses. Upload JSONL files from local session directories as-is. Useful for sharing debugging workflows, benchmarking agent behavior, or building training data from real coding sessions.
