copilot

copilot-plugin-cc

A Claude Code plugin that integrates GitHub Copilot CLI — bringing multi-model AI access, codebase exploration, and implementation planning directly into your Claude Code sessions.

What this plugin does

This plugin wraps the standalone copilot CLI to let you:

• Ask — Send any question or task to Copilot CLI
• Explore — Delegate codebase analysis to Copilot's built-in Explore agent
• Plan — Get a second-opinion implementation plan from a different AI
• GitHub — Query issues, PRs, and Actions using Copilot's built-in GitHub MCP
• Multi-model — Run prompts with GPT, Gemini, or other models available through Copilot

Prerequisites

• GitHub Copilot CLI (copilot command)
• Active GitHub Copilot subscription
• Node.js 18.18.0 or later

Installation

/plugin install 7nohe@copilot-plugin-cc

Then verify the setup:

/copilot:setup

Commands

Command	Description
/copilot:setup	Check copilot CLI installation and authentication
/copilot:ask <prompt>	Send a question or task to Copilot CLI
/copilot:explore <topic>	Analyze the codebase using Copilot's Explore agent
/copilot:plan <task>	Get an implementation plan as a second opinion
/copilot:github <query>	Query issues, PRs, Actions via Copilot's GitHub MCP
/copilot:multi-model --model <name> <prompt>	Run a prompt with a specific AI model

Options

• --model <name> — Choose a specific model (available on ask, plan, multi-model)
• --yolo — Skip Copilot's permission prompts (available on ask, multi-model)

GitHub query examples

/copilot:github List open issues labeled bug
/copilot:github Summarize PR #42 and its review comments
/copilot:github Why did the last CI run fail?
/copilot:github Who is assigned to issue #10?

Model examples

/copilot:multi-model --model gpt-5.3-codex Explain the auth middleware
/copilot:multi-model --model gemini-3-pro Suggest improvements for the API layer

Architecture

This plugin is intentionally simple and stateless:

• No SDK dependency — Calls copilot -p directly via shell execution
• No background jobs — All commands run in the foreground
• No persistent state — No job tracking or session management
• Handler registry — Clean Map-based dispatch in hub.mjs

How it differs from other Copilot plugins

This plugin focuses on leveraging Copilot CLI's unique strengths:

1. Built-in GitHub MCP — Query issues, PRs, and Actions without separate gh CLI setup
2. Multi-model access — Use GPT, Gemini, and other models Copilot supports
3. Independent context — Copilot runs in its own context with its own file access
4. Second opinions — Get a different AI's perspective on architecture, plans, or code
5. Lightweight — No SDK, no state, no background processes
