# Enforce Coding-Agent Write and Shell Policies with Probity

Use Probity when Claude Code, Codex, or GitHub Copilot CLI should be blocked from unsafe file writes or shell commands before they happen.

## Prerequisites

Node.js/npm; @nizos/probity package; probity.config.ts; one supported agent host such as Claude Code, Codex, or GitHub Copilot CLI.

## Installation

Install or set up from the source-backed instructions:

Install with npm install -D @nizos/probity, create probity.config.ts with scoped rules such as enforceTdd(), then follow docs/setup.md to wire Probity into Claude Code, Codex, or GitHub Copilot CLI.
