Intro

cc-safety-net adds a safety gate for Claude Code tool calls: explain/score risky commands (rm -rf, git resets) and validate custom rules (1,330★).

Best for: Teams letting agents run shell commands but needing guardrails, auditability, and consistent “deny by default” rules

Works with: Claude Code native hooks/plugins, npx-based installs, and JSON outputs for automated gating

Setup time: 5-12 minutes

Main

Command risk UX: provides explainers for destructive commands before execution.
Custom rules: supports defining policy rules (block global npm installs, dangerous docker actions, etc.).
Validation gate: documents a --verify-config step so config changes are checked before you rely on them.
Agent-friendly outputs: includes JSON mode so an agent runner can decide allow/deny deterministically.

FAQ

Is this only for Claude Code?: It is designed around Claude Code hooks/commands, but the patterns are reusable for other agent runners.
How do I start safely?: Run doctor, then try explain on a few commands you commonly see in agent sessions.
Why validate configs?: A broken rule file can silently disable protections; validation keeps the gate trustworthy.
