TL;DR: GitHub Copilot is moving from premium-request quotas to per-token billing on June 1st. Agentic workflows can now cost more than the old premium-request mental model suggests.
Just let your agent do it
Don't want to run this yourself? Paste this prompt into your coding agent:
Clone https://github.com/PanAchy/copilot-arewecooked, install dependencies, build it, and run it.
Then open the generated HTML report and tell me whether or not I'm going to be cooked under the new Copilot AI-credit billing.
Setup
The quickest way (requires Node.js 20+):
npx copilot-arewecooked
Or clone and build:
git clone https://github.com/PanAchy/copilot-arewecooked.git
cd copilot-arewecooked
npm install
npm run build
npm startBy default, this writes an HTML report like:
copilot-report-YYYY-MM-DD.html
Options
| Flag | Description |
