## Useful for

- Run Claude Code in an isolated VM so it can install packages and edit files without touching the host
- Spin up a separate VM per project with coop up and coop claude to run agents in parallel
- Recreate a clean VM after risky agent experiments instead of manually cleaning up the system

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.
