Copilot plugin for Claude Code

This project is based on or inspired by the Codex Plugin, licensed under the Apache License 2.0. Modifications have been made.

Use GitHub Copilot from inside Claude Code for code reviews or to delegate tasks to Copilot.

This plugin is for Claude Code users who want an easy way to start using GitHub Copilot from the workflow they already have.

What You Get

• /copilot:review for a normal read-only Copilot review
• /copilot:adversarial-review for a steerable challenge review
• /copilot:rescue, /copilot:status, /copilot:result, and /copilot:cancel to delegate work and manage background jobs

Requirements

• GitHub account with Copilot access (Individual, Business, or Enterprise plan)
  • Usage will contribute to your Copilot usage limits. Learn more.
• Node.js 18.18 or later
• GitHub CLI (gh) 2.40 or later — used for authentication and Copilot invocation

Install

Add the marketplace in Claude Code:

/plugin marketplace add satwik6941/Github-Copilot-Plugin

Install the plugin:

/plugin install copilot@Github-Copilot-Plugin

Reload plugins:

/reload-plugins

Then run:

/copilot:setup

/copilot:setup will tell you whether Copilot is ready. If the GitHub CLI is missing or you are not authenticated, it will guide you through the steps.

If you prefer to set up manually, install the GitHub CLI and authenticate:

gh auth login

After install, you should see:

• the slash commands listed below
• the copilot:copilot-rescue subagent in /agents

One simple first run is:

/copilot:review --background
/copilot:status
/copilot:result

Usage

/copilot:review

Runs a normal Copilot review on your current work. It gives you the same quality of code review as running a review inside Copilot directly.

[!NOTE] Code review especially for multi-file changes might take a while. It's generally recommended to run it in the background.

Use it when you want:

• a review of your current uncommitted changes
• a review of your branch compared to a base branch like main

Use --base <ref> for branch review. It also supports --wait and --background. It is not steerable and does not take custom focus text. Use /copilot:adversarial-review when you want to challenge a specific decision or risk area.

Examples:

/copilot:review
/copilot:review --base main
/copilot:review --background

This command is read-only and will not perform any changes. When run in the background you can use /copilot:status to check on the progress and /copilot:cancel to cancel the ongoing task.

/copilot:adversarial-review

Runs a steerable review that questions the chosen implementation and design.

It can be used to pressure-test assumptions, tradeoffs, failure modes, and whether a different approach would have been safer or simpler.

It uses the same review target selection as /copilot:review, including --base <ref> for branch review. It also supports --wait and --background. Unlike /copilot:review, it can take extra focus text after the flags.

Use it when you want:

• a review before shipping that challenges the direction, not just the code details
• review focused on design choices, tradeoffs, hidden assumptions, and alternative approaches
• pressure-testing around specific risk areas like auth, data loss, rollback, race conditions, or reliability

Examples:

/copilot:adversarial-review
/copilot:adversarial-review --base main challenge whether this was the right caching and retry design
/copilot:adversarial-review --background look for race conditions and question the chosen approach

This command is read-only. It does not fix code.

/copilot:rescue

Hands a task to Copilot through the copilot:copilot-rescue subagent.

Use it when you want Copilot to:

• investigate a bug
• try a fix
• continue a previous Copilot task
• take a faster pass without spending premium quota

[!NOTE] Depending on the task these jobs might take a long time and it's generally recommended to force the task to be in the background or move the agent to the background.

It supports --background, --wait, --resume, and --fresh. If you omit --resume and --fresh, the plugin can offer to continue the latest rescue thread for this repo.

Examples:

/copilot:rescue investigate why the tests started failing
/copilot:rescue fix the failing test with the smallest safe patch
/copilot:rescue --resume apply the top fix from the last run
/copilot:rescue --background investigate the flaky integration test
/copilot:rescue --background investigate the regression

You can also just ask for a task to be delegated to Copilot:
