Create, update, validate, operate, and troubleshoot Dev Container setups, including `devcontainer.json`, local or published Dev Container Features, and `devcontainer` CLI workflows.
My personal collection of GitHub Copilot customizations — prompts, instructions, agents, and installable plugins — tailored to my specific workflows and preferences.
Inspired by github/awesome-copilot.
