CC Safety Net
A pre-command hook that checks shell operations and blocks or warns about commands that could cause data loss.
Project overview
CC Safety Net is a agent plugin built around a pre-command hook that checks shell operations and blocks or warns about commands that could cause data loss. Its value is practical: block dangerous commands and detect file-deletion risk are available from one documented project, while the repository remains inspectable before it is added to an agent workflow.
Core capabilities
Block dangerous commands
Block dangerous commands is documented in the repository README or its component instructions. Review the linked source for current behavior and requirements.
Detect file-deletion risk
Detect file-deletion risk is documented in the repository README or its component instructions. Review the linked source for current behavior and requirements.
Check installation health
Check installation health is documented in the repository README or its component instructions. Review the linked source for current behavior and requirements.
Provide safety warnings
Provide safety warnings is documented in the repository README or its component instructions. Review the linked source for current behavior and requirements.
Installation and usage
Set up CC Safety Net from its public GitHub instructions, keep the initial permission scope small, and verify it with a low-risk task before regular use.

Read the repository README and license first. Confirm the current host, prerequisites, destination paths, and permissions. Follow the repository's documented method, keep credentials out of files and logs, and start with the least-privilege or read-only option where available. Afterward, run a small verification and report the exact changes, commands, configuration path, and result. Ask before overwriting files or requesting broader access.- Node.js 18+
- Claude Code supports hooks
npx -y cc-safety-net@latest install- 1Review prerequisites and scope
Read the README, confirm the target host, and prepare these prerequisites: Node.js 18+; Claude Code supports hooks. Check destination paths and permissions before making changes.
- 2Apply the documented setup
Run the documented command: npx -y cc-safety-net@latest install
- 3Verify with a small task
Restart or reload the target agent, confirm that CC Safety Net appears in its installed extensions or skills, and run the smallest documented example before using it on important work.

- Static command analysis cannot cover every variant or indirect execution path
- Complex shell syntax, including PowerShell, can still evade detection
Use cases
Development environments where agents run shell commands
Development environments where agents run shell commands is a practical fit when the repository's documented prerequisites and permission model match the current environment.
Protect projects containing important files
Protect projects containing important files is a practical fit when the repository's documented prerequisites and permission model match the current environment.
Add an extra confirmation layer to a personal workflow
Add an extra confirmation layer to a personal workflow is a practical fit when the repository's documented prerequisites and permission model match the current environment.
Assessment
This assessment is based on the repository README, component documentation, license, and maintenance metadata. Installation and health-check commands are straightforward; The project has a focused scope around destructive commands. The main trade-offs are also clear: Static command analysis cannot cover every variant or indirect execution path; Complex shell syntax, including PowerShell, can still evade detection. No local installation or functional test was claimed during cataloging.
Why it may be useful
- Installation and health-check commands are straightforward
- The project has a focused scope around destructive commands
What to know first

Getting started
- Set up CC Safety Net from its public GitHub instructions, keep the initial permission scope small, and verify it with a low-risk task before regular use.
- The repository describes CC Safety Net as a pre-command hook that checks shell operations and blocks or warns about commands that could cause data loss.
- Its main capabilities include block dangerous commands, detect file-deletion risk, check installation health, provide safety warnings. The documented facts include pre-execution hook, destructive shell command detection, built-in doctor command, update and uninstall commands.
- Restart or reload the target agent, confirm that CC Safety Net appears in its installed extensions or skills, and run the smallest documented example before using it on important work.
Configuration
