CC Safety Net, by kenryu42, blocks destructive commands and access to secrets before a coding agent's tool call runs. It parses what a command does, so wrapping it in bash -c or python -c, or reordering flags, does not slip past. The README lists blocks for git reset --hard, git push --force, rm -rf on dangerous targets and curl piped to bash, and for reading SSH keys, .env files, ~/.aws and CLI credentials. A GUI started with npx cc-safety-net gui picks the Standard, Strict or Paranoid preset, and rulebooks add packs for Terraform, AWS, gcloud and Azure. It supports several coding CLIs on Windows, macOS and Linux. Install with npx -y cc-safety-net@latest install. The licence is MIT and the repository was last pushed on 30 October 2026. It suits anyone running agents with broad shell access. A limit is that rules block, not sandbox, so it complements isolation. We have not run it ourselves for this note.
