I’m sure this is documented somewhere, but it’s wild that Claude/Claude Code has a 10GB VM image for running sandboxed code.

Common operations:

• Git commands (git status, git diff, git commit, etc.)
• Package managers (npm install, brew, pip, etc.)
• Build tools (make, cargo build, npm run build)
• Running tests (pytest, npm test, cargo test)
• File operations that require shell commands
• Any custom scripts or commands you ask me to run

Sadly, it does not have cowsay installed.
