| # Trajectory Reader | |
| Renders the `messages` (or `conversations`, `prompt`/`completion`, …) column of | |
| any Hugging Face dataset row as a chat transcript: system / user / assistant / | |
| tool turns, reasoning blocks, tool calls with arguments, tool results, plus the | |
| `tools` schema and the remaining columns in a side rail. | |
| **Permissions are the Hub's.** This page ships no data and no token, and there is | |
| no token box — signing in with your Hugging Face account is the only way in | |
| (NewsBreak members only). Every request goes from your browser straight to | |
| `datasets-server.huggingface.co` / `huggingface.co` carrying your own OAuth | |
| token, so you can only open datasets you already have access to, and no | |
| credential is ever typed into or stored by this page. | |
