+# Cursor Rules derived from .github/AGENTS.md
+
+## Read AGENTS.md First
+All contributors must read `.github/AGENTS.md` for complete guidelines. If any rule here conflicts with that file, **AGENTS.md** takes precedence.
+
+## Coding Standards
+- Format with `magex format:fix`.
+- Lint with `magex lint` and vet with `magex vet`.
+- Run `magex test` before committing.
+- Follow Go naming and commenting conventions described in AGENTS.md.
+
+## Commit Messages
+- Use the format `<type>(<scope>): <imperative short description>`.
+- Types include `feat`, `fix`, `docs`, `test`, `refactor`, `chore`, `build`, `ci`.
+
+## Pull Requests
+- Title format: `[Subsystem] Imperative and concise summary of change`.
+- Description must include the sections:
+  1. **What Changed**
+  2. **Why It Was Necessary**
+  3. **Testing Performed**
+  4. **Impact / Risk**
+
+## Dependency Management
+- Manage modules with `magex tidy` after import changes.
+
+## Security Reporting
+- Do not open public issues for vulnerabilities.
+- Follow `SECURITY.md` for responsible disclosure.
