Instructions, prompts, and configurations to help you make the most of GitHub Copilot.
Canonical Copilot Collections is a repository for organizing and distributing GitHub Copilot instructions, prompts, agents, and skills across Canonical repositories. Teams configure repositories to subscribe to shared collections, such as Python, documentation, or Juju development guidance, and keep those assets synchronized.
This repository also configures its own agents. See what copilot-collections tells them →
