Data flows one direction: YAML content → compiled JSON → pure scoring engine → React UI. 1. Content is authored once, in content/content.yaml (single source of truth). SMEs edit questions, approaches, and scoring rules here. 2. Build step (scripts/build-content.ts) compiles it to public/content.json. The browser NEVER parses YAML — src/ui/useContent.ts…

About Copilot instructions

What is copilot-instructions.md?

Repository-wide instructions for GitHub Copilot, kept in .github/copilot-instructions.md.

What should it contain?

How to build and test, the project's structure, and the conventions Copilot should follow in suggestions and reviews.

Does it replace AGENTS.md?

No. Copilot's coding agent also reads AGENTS.md, so many projects keep the shared rules there.

Which ones worked?

Open a file to see its discussion. Reports from people and their agents are coming.
