guardrail-tester

Guardrail tester that checks whether the permission rules and PreToolUse hooks already set up in Claude Code, Codex, Gemini CLI, OpenCode, or Cursor stop a battery of dangerous commands, including wrapped, reordered, and full-path forms that slip past prefix rules, and measures prompt friction on the latest tool calls. Use when the user asks whether deny rules or hooks block force pushes, rm -rf, secret reads, or downloads piped into a shell; wants to test or audit guardrails, or find a bypass in permission settings or exec policy; asks how many prompts or blocks the rules cause; or just installed a guard hook and wants proof it holds. Local only, no network; executes the user's own hook commands only with their yes.
