The current system prompt already states "Avoid `any` type - use precise types", but doesn't explicitly cover `this` context typing. The assistant wrote code with `graph.forEach(function(this: TaskGraph) {...})` which requires explicit `this` type annotation in TypeScript strict mode. Adding a specific rule about `this` type annotations will prevent similar errors and ensure proper TypeScript strictness compliance. + +### Changes +- Added explicit rule for `this` context type annotations in callbacks/iterators to prevent implicit 'any' TypeScript errors + +### Original Prompt +``` +You are powered by the model named MiniMax-M2.1.
