copilot

copilot-plugin-cc

A Claude Code plugin that lets you use GitHub Copilot CLI from within Claude Code — for code reviews, adversarial design challenges, and task delegation.

Inspired by openai/codex-plugin-cc, which bridges Claude Code → Codex. This plugin bridges Claude Code → GitHub Copilot instead.

Prerequisites

• Claude Code (with plugin support)
• Node.js ≥ 18.18
• GitHub Copilot CLI — install with:

  npm install -g @github/copilot
  

• GitHub authentication — run copilot and use /login, or set COPILOT_GITHUB_TOKEN

Installation

To install the plugin from Claude Code, first add the repository as a marketplace, then install the copilot plugin:

claude plugin marketplace add https://github.com/DarioDML/copilot-plugin-cc
claude plugin install copilot

Or install from a local checkout:

claude plugin marketplace add ./path/to/copilot-plugin-cc
claude plugin install copilot

Commands

Command	Description
/copilot:setup	Check if the Copilot CLI is installed and authenticated
/copilot:review	Run a code review on your uncommitted changes
/copilot:review --base main	Review your branch diff against main
/copilot:adversarial-review	Challenge your implementation and design choices
/copilot:rescue <task>	Delegate a task to Copilot (investigate, fix, build)
/copilot:status	Show active and recent Copilot jobs
/copilot:result [job-id]	Show output of a completed job
/copilot:cancel [job-id]	Cancel a running background job

Examples

# Check setup
/copilot:setup

# Review working tree changes
/copilot:review

# Review branch vs main
/copilot:review --base main

# Challenge the design
/copilot:adversarial-review focus on error handling

# Delegate a task
/copilot:rescue fix the failing unit tests in src/utils

# Check on background jobs
/copilot:status

# Get the result
/copilot:result

How It Works

1. Claude Code reads the plugin's command markdown files
2. When you run /copilot:review, Claude executes the companion script
3. The companion script invokes copilot -p "<review prompt>" with your diff context
4. Copilot CLI processes the request and returns its analysis
5. Claude presents the output verbatim in your session
