## Overview

agent-scaffold is a Claude Code and GitHub Copilot CLI plugin that prepares another repository for safer AI-assisted development. A user invokes the scaffold skill; it inspects the target project, then generates shared and tool-specific guidance, safety hooks, skill guides, and a git-conflict sub-agent. The generated hook configurations dispatch guard, prompt-reminder, and activity-logging scripts. The README documents these product capabilities; the sampled scaffold source is partial, so links for unsampled generation steps are based on that documentation rather than inspected implementation.
