Fable 5 Claude Code Traces
A full, scrubbed release of Fable 5 Claude Code session traces for researchers studying real coding-agent behavior: multi-turn prompts, assistant responses, tool calls, command output, retries, and session-level workflow metadata.
This release keeps the full package intact: 18 sessions, 9,497 JSONL events, 0 excluded rows, and 0 quarantine files. The traces are preserved in the native agent-event format so they can be inspected in Hugging Face Agent… See the full description on the dataset page: https://huggingface.co/datasets/AlinCiocan/fable-5-claude-code-traces.Fable-5-traces

🍄 Super Fable Bros. — Claude Fable 5.1 Agent Trajectory
The complete, unedited coding-agent session in which Claude Fable 5.1 (claude-fable-5-1 — mind the minor version, the point-one is the whole point) one-shotted a
playable Super Mario Bros. World 1-1 remake in a single HTML file — zero dependencies,
zero external assets, WebAudio chiptune synth, hand-encoded pixel sprites.
