# AI Agent System

A marketplace plugin that installs agents, skills, hooks and slash commands for Claude Code and GitHub Copilot CLI, adding a session protocol and review gates for governed AI-assisted development.

AI Agent System is a plugin distributed through a Claude Code marketplace and a GitHub Copilot CLI marketplace from the same repository. Installing it adds a full set of specialized agent roles (analyst, architect, implementer, QA, security, devops and others), skills, slash commands, and lifecycle hooks that run before and after tool use.

The hooks enforce a session protocol and review gates intended to give platform teams and engineering managers governance over AI-assisted coding, including ADR-steered agent behavior. The project-toolkit plugin's hooks are written in Python and require Python 3.10 or newer; without it, hooks are skipped and the session still works, but the security and review checks they provide do not run.

The project is written mainly in Markdown and distributed as a Claude Code and Copilot CLI plugin under the MIT license.
