Initial sync with [canonical/copilot-collections](https://github.com/canonical/copilot-collections). Also adds a CI job from copilot-collections that runs once a week, checks for new releases, and creates a PR if there's been an update. The `.github/skills/` and `.github/instructions/` are generated by copilot-collections. Feel free to read through them, but the contents shouldn't be modified here. ### Q & A **Why Snapcraft?** Snapcraft is a good proving ground because it gets a fair amount of activity and I review most PRs. **Can I use these instructions locally?** Yes. For Copilot CLI, they're loaded automatically for Snapcraft. If you want them to work for other projects, then ensure your local copy of Snapcraft has these instructions and run `export COPILOT_CUSTOM_INSTRUCTIONS_DIRS=<path-to-snapcraft>`. `/instructions` in copilot CLI will show you what's been loaded. **Will we add this to all our repos?** Likely, depending on how this trial goes. **Does it improve the reviews?** I think so, but you can judge that yourself. Here's the same doc change [with](https://github.com/canonical/snapcraft/pull/6194) and [without](https://github.com/canonical/snapcraft/pull/6195) the instructions. Copilot reviews on GH are a bit annoying because they only leave so many comments per review, so you have to do many iterations. They aren't that deterministic either. Here are a few comments that are based on the custom instructions <img width="636" height="192" alt="image" src="https://github.com/user-attachments/assets/28c9ebec-bc94-45ff-acb6-c4d4ecd298f3" /> <img width="636" height="192" alt="image" src="https://github.com/user-attachments/assets/85f97765-e0f4-49f2-b749-885307e16c34" /> <img width="636" height="192" alt="image" src="https://github.com/user-attachments/assets/24560756-a530-4f05-bc5e-724709230a67" /> --- - [x] I've followed the [contribution guidelines](https://github.com/canonical/snapcraft/blob/main/CONTRIBUTING.md). - [x] I've signed the [CLA](http://www.ubuntu.com/legal/contributors/). - [x] I've successfully run `make lint && make test`. - [ ] I've added or updated any relevant documentation. - [ ] In documents I changed, I [added a meta description](https://canonical-starflow.readthedocs-hosted.com/how-to/add-a-page-meta-description/) if one was missing. - [ ] I've updated the relevant release notes.
