copilot-plugin-manager 0.2.1

Rust-first GitHub Copilot asset manager with a thin Python wrapper

Copilot Plugin Manager (cpm)

Copilot Plugin Manager or just cpm is a package manager for GitHub Copilot assets. It helps you define, install, update, inspect, and reset plugins, skills, agents, MCPs, hooks, workflows, and instructions with a reproducible manifest and lockfile workflow.

The package is published as copilot-plugin-manager, but the command you run is cpm.

Why use cpm?

• keep your Copilot setup in cpm.toml
• lock resolved revisions in cpm.lock
• install assets into repository-local or global Copilot locations
• manage assets from marketplace specs, GitHub sources, and local paths
• inspect drift with overview, show, tree, doctor, and status

Install

For one-off usage:

uvx --from copilot-plugin-manager cpm --help

or:

uvx copilot-plugin-manager --help

For a persistent install:

uv tool install copilot-plugin-manager

Or with pip:

pip install copilot-plugin-manager

Quick start

If you installed cpm, use cpm .... If you prefer not to install it globally, replace cpm with uvx --from copilot-plugin-manager cpm in the examples below.

Initialize a new project:

cpm init

Add a plugin and a skill:

cpm add spark@copilot-plugins --plugin
cpm add https://github.com/anthropics/skills/tree/main/skills/pdf --skill

Apply the lockfile to disk:

cpm sync

Inspect what is installed:

cpm list
cpm status

Common examples

Install a plugin from a Copilot marketplace registry:

cpm add spark@copilot-plugins --plugin

Registry plugins delegated to copilot plugin install are effectively global installs. Native plugin bundles added from GitHub tree URLs or local paths still honor local vs global scope.

Install a plugin bundle from a GitHub tree URL:

cpm add https://github.com/github/awesome-copilot/tree/main/plugins/testing-automation --plugin

Install a skill from GitHub:

cpm add https://github.com/anthropics/skills/tree/main/skills/pdf --skill

Inspect one asset in detail:

cpm show testing-automation --plugin

Core commands

Command	What it does
cpm init	Create a new cpm.toml and cpm.lock
cpm add	Add an asset to the manifest and resolve it
cpm sync	Install everything recorded in cpm.lock
cpm update	Update one or all managed assets
cpm remove	Remove a managed asset
cpm lock	Resolve without installing
cpm reset	Remove managed state and/or installed assets
cpm overview	Show the combined manifest, lockfile, and disk view
cpm list	List installed assets
cpm show	Show full details for a single asset
cpm tree	Show the dependency tree
cpm doctor	Verify installed files match the lockfile
cpm status	Show drift between manifest, lockfile, and disk

How cpm works

• cpm.toml records the assets you want
• cpm.lock records the resolved versions and hashes
• cpm sync materializes those assets into .github/ for local scope or ~/.copilot/ for global scope
• concrete GitHub file and tree sources are fetched directly by cpm
• delegated Copilot plugin installs are used where the Copilot CLI is the installer of record
