 ## 🚫 Avoid / Anti-Patterns
 
 - **Do NOT access tensors by index:** Avoid using `tensors[0]` or `tensors[1]` throughout the function body. Always destructure and name them explicitly.
+- **Do NOT name options parameters `opts`:** Always name options function parameters `options` (e.g. `options?: { threshold?: number }`). Suffixes like `Opts` for types or properties (e.g. `MyTaskOptions`, `ModelOpts`, `modelOpts`) are acceptable.
 - **Do NOT define extra inner helper functions:** You must define **exactly two** inner functions inside the `create<Task>` constructor: the `dispose` function and the task `worklet` executor function. **Push back hard against implementing any other helper closures inside the constructor scope.** Placing other helper functions (especially those that are called from inside the worklet and use the `create<Task>` scope variables) inside `create<Task>` creates implicit dependencies and closures that capture variables, making the code extremely difficult to reason about and debug.
 - **Do NOT leak raw Tensors to consumers:** The returned methods must never return raw `Tensor` objects to the API consumer. Always convert output data to standard JavaScript values/objects before returning.
 - **Do NOT cross thread boundaries unnecessarily:** Minimize passing heavy objects between JS and the Worklet thread to avoid serialization overhead.

 ## 💡 Key Coding Conventions
 
 - **Worklets**: Ensure all TypeScript functions directly wrapping native JSI calls start with the `"worklet";` directive so they are compatible with worklet-based libraries (e.g., React Native Reanimated).
+- **Options Parameter Naming**: Always name function and method options parameters `options` (not `opts`, `optsObj`, `taskOpts`, or `chunkOpts`). Using `Opts` as a type or property suffix (e.g. `ModelOpts`, `TaskOpts`, `modelOpts`) is acceptable.
 - **Memory Management**: When writing native C++ code with JSI, pay close attention to JSI reference management and handle ExecuTorch lifecycle states safely.
 - **Keep Core Clean**: Always build on top of core primitives. Do not modify files in `cpp/core/` or `src/core/` unless you are fixing a bug in the foundational runtime.
