code-review-graph

tirth8205/code-review-graph/.github/copilot-instructions.md

This project has a knowledge graph. Start with the code-review-graph MCP tools to narrow scope, then read the source. The graph is cheaper than scanning files and gives you structural context (callers, dependents, test coverage) that file search cannot. - Narrow scope with the graph, then read the source. Do not change code from graph output alone. - For any non-trivial change, read the implementation and the relevant tests before concluding. - Verify the exact source when touching behavior, database…

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.
