## Useful for

- Run the built-in order fulfilment example via s1 run --env order:ship_fastest_gift
- Connect an MCP server as an environment and compile its tools into actions
- Drive a browser through DOM controls with a finite action space

## Why it’s here

- 1 star so far today, about 24 expected by the end of the day.
- The spike has held for 3 days in a row — not a one-off blip.
- The repository is 3 days old and already has 96 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.
- Top new repositories this week: #197.

## Star trust

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
