Why it matters

Useful for platform teams thinking about agent safety on developer machines. Treat it as a preview: read the warning, test only in a sandbox, and do not assume the current policy defaults are production-safe.

Who should use it

AI infrastructure teamssecurity engineersWindows/WSL platform developers

Who should skip it

Skip or sandbox it if you cannot review permissions, data access, and failure modes before use.

Risk explanation

runs untrusted code; early preview with known overly permissive policy cases; security-sensitive.
