+# Agent Instructions for Monix
+
+This file contains mandatory rules for AI agents (Copilot, Claude, Cursor, etc.) working on this repository.
+**Any violation is a CI-breaking mistake!**
+
+---
+
+## Code rules
+
+- Never workaround the compiler, make an effort to solve errors in an idiomatic way:
+  - Avoid `asInstanceOf` downcasting, unless there's no other way (e.g., untagged union types in Scala 3).
+  - `@nowarn` annotations, or other ways for supressing warnings/errors, are not permitted without the user's consent.
+    - We fix warnings, we don't ignore them.
+- Use package imports, instead of fully qualified names.
+- Make an effort to write idiomatic, yet performant Scala code.
