+# Cursor Rules for ZITADEL
+
+You are working in the ZITADEL monorepo. 
+
+**ALWAYS** read `AGENTS.md` files in this order:
+1. Root `AGENTS.md`
+2. The nearest scoped `AGENTS.md` for the files you are changing
+
+If you touch Go code or run Go tooling, inspect `go.mod` first for the required Go version/toolchain.
+
+Use verified Nx targets only. If a target is unclear or missing, run `pnpm nx show project <project>`.
