AI Agents: Multi-Agent Toolkit for Claude Code and GitHub Copilot CLI

AI Agents is an open-source multi-agent toolkit for software development with Claude Code, GitHub Copilot CLI, and VS Code Copilot Chat. An orchestrator routes work across 30 specialized agents, including analyst, architect, code-reviewer, dependency-auditor, implementer, critic, QA, security, and DevOps, to plan, build, review, and ship code with explicit handoffs and quality gates at each stage.

Built for platform teams, engineering managers, and organizations that want AI-assisted development with real governance: plan-to-ship lifecycle skills (/spec, /plan, /build, /test, /review, /ship) in both CLIs, run as slash commands in Claude Code, review gates and a session protocol in both CLIs, and ADR-steered agent behavior. Optional cross-session memory is available via Serena. Install from the plugin marketplace with /plugin marketplace add rjmurillo/ai-agents then /plugin install project-toolkit@ai-agents, in Claude Code or Copilot CLI. MIT licensed.

Why AI Agents

• Orchestrated specialists. An orchestrator routes work to specialist agents (analyst, architect, milestone-planner, implementer, critic, qa, security, devops) with explicit handoffs.
• Plan-to-ship lifecycle. Six commands cover the path in Claude Code: /spec, /plan, /build, /test, /review, /ship.
• Review gates that loop back. The critic returns APPROVED, APPROVED_WITH_CONCERNS, NEEDS_REVISION, or BLOCKED. NEEDS_REVISION sends the plan back to the agent that produced it. A QA failure sends the work back to the implementer.
• One marketplace URL, two CLIs. The same repository URL installs as a plugin marketplace in Claude Code and in GitHub Copilot CLI.
• VS Code Copilot Chat support. Agents also load in VS Code Copilot Chat from .github/agents/.
• MIT licensed.

Is AI Agents right for you?

Good fit:

• You want governed plan, build, review, and ship stages in Claude Code or GitHub Copilot CLI.
• You want a critic, QA, and security agent to check work before it merges.
• Your team uses both Claude Code and Copilot CLI and wants one toolkit for both.

Not a fit:

• You only want a single-agent assistant. Claude Code or Copilot CLI alone covers that.
• You need Gemini CLI or Codex CLI. This README documents Claude Code, GitHub Copilot CLI, and VS Code Copilot Chat only.
• You want a tmux-driven pipeline across many CLIs. AgentMux is an option there.

Fastest Start

Each AI tool has its own native marketplace flow. This repo ships a Claude Code marketplace at .claude-plugin/marketplace.json and a Copilot CLI marketplace at .github/plugin/marketplace.json, so the same repository URL works in both CLIs. Pick yours and paste the command(s) inside the CLI session.

Claude Code. Two steps: register the marketplace, then install the toolkit. Restart Claude Code when it finishes.

/plugin marketplace add rjmurillo/ai-agents
/plugin install project-toolkit@ai-agents

GitHub Copilot CLI. The same two steps. No restart needed afterward; Copilot CLI picks agents up automatically.
