# Embodied First Exam: agent runs

The agent runs behind the run viewer of the [Embodied First Exam](https://www.embodied-first-exam.ai), a benchmark
for code agents in robotics: every step, tool call and picture an agent saw while it sat a task, the verifier's replay of
its final answer, and the agent's full trajectory for download.

## Layout

```
index.json                              runs per suite, solved per suite, runs per setting
index/<suite>.json                      one row per run of the suite
runs/<h2>/<slug>/run.json               one run: every step, tool call and output
runs/<h2>/<slug>/replay.mp4             the verifier's replay of the final answer (when there is one)
runs/<h2>/<slug>/poster.jpg             the replay's last frame
runs/<h2>/<slug>/steps.bin              the pictures the agent saw, concatenated; run.json gives each as [offset, length]
runs/<h2>/<slug>/trajectory.jsonl.gz    the agent's full trajectory, one event per line
```

`h2` is the first two hex characters of sha1(slug). A slug is `<task dir>--<last 7 characters of the trial id>`.
`index.json` also names, under `linked`, a few earlier runs that the website links directly; they are kept here but
are not listed in the shards.

## Contributing

The runs come from the exam's own evaluations. Please do not open pull requests on this repository.

## Licence

The trajectories, pictures and replays come from agent runs on the exam's tasks, made by the exam's maintainers. The
scenes and assets keep the licences of their upstream benchmarks; see each suite's page on the exam's website.
