Install CC Safety Net for Your AI Coding Agent

CC Safety Net installs as a plugin or hook directly inside your AI coding agent — no separate process or daemon required. Node.js 18 or higher must be available on your system before you begin. Choose your agent below to see the exact steps.

Run these three commands inside Claude Code to install from the plugin marketplace:

/plugin marketplace add kenryu42/cc-marketplace
/plugin install safety-net@cc-marketplace
/reload-plugins

Enable auto-updatesTo keep CC Safety Net up to date automatically, run /plugin, navigate to Marketplaces, select cc-marketplace, and enable auto-update.

Install CC Safety Net with OpenCode’s native plugin command:

opencode plugin -g cc-safety-net

OpenCode can sometimes keep using a stale cached plugin version. To force OpenCode to reinstall cc-safety-net, remove its cached package and reinstall:

rm -rf ~/.cache/opencode/packages/cc-safety-net@latest
opencode plugin -g -f cc-safety-net@latest

If you prefer pinning a specific version:

rm -rf ~/.cache/opencode/packages/cc-safety-net@latest
opencode plugin -g -f cc-safety-net@<version>

Restart OpenCode after updating so the plugin is loaded from the refreshed cache.

Install CC Safety Net into your Kimi CLI config:

npx -y cc-safety-net hook install --kimi-cli

Install CC Safety Net with Pi’s package installer:

pi install npm:cc-safety-net

Install the Gemini Safety Net extension with a single command:

gemini extensions install https://github.com/kenryu42/gemini-safety-net

The extension is active immediately — no restart required.

Run the following inside GitHub Copilot CLI:

/plugin install kenryu42/copilot-safety-net

Restart Copilot CLI after installing the plugin for it to take effect.

Codex requires a few extra steps to enable plugin hook support before installing.Step 1 — Enable plugin hooksAdd the following to ~/.codex/config.toml:

[features]
plugin_hooks = true

Verify Your Installation

After installing, run the doctor command to confirm CC Safety Net is wired up correctly and blocking commands as expected:

npx cc-safety-net doctor
# or with bun
bunx cc-safety-net doctor

The doctor command runs through the following checks:

Check	What It Does
Hook Integration	Verifies the plugin is properly configured for each supported platform
Self-Test	Runs sample commands to confirm blocking works correctly
Configuration	Validates any custom rules in your user and project configs
Environment	Shows the status of mode flags (`CC_SAFETY_NET_STRICT`, `CC_SAFETY_NET_PARANOID`, etc.; legacy `SAFETY_NET_*` also listed when set)
Recent Activity	Summarizes blocked commands from the last 7 days
System Info	Displays versions of all relevant tools
Update Check	Checks whether a newer version of CC Safety Net is available

If any check fails, the output includes a description of the problem and suggested remediation steps.
