Same. The issue with Anthropics models is that (speaking regarding code generation) they REFUSE any kind of comment override instructions. I've tried everything and no matter what, after a few turns, they resort to generating the same overtly verbose junk. Bun's codebase is littered with them See

   // `HANDLE` is an opaque kernel handle (kernel32 validates and returns 0/FALSE
   // on a non-console handle); every out-param is `&mut T` to a `#[repr(C)]` POD,
   // ABI-identical to the Win32 `LP*` pointer (thin non-null). The reference type
   // encodes the only pointer-validity precondition, so `safe fn` discharges the
   // link-time proof. (`bun_windows_sys::kernel32` declares these with `*mut`;
   // redeclared locally so the legacy-conhost cursor path below is plain calls.)

or

   // Progress's terminal handle is the canonical `output::File` (vtable-backed
   // stderr/File from `OutputSinkVTable`). The duplicate `ProgressTerminalVTable`
   // from B-0 round 1 is removed; tty/ansi/winsize route through    the new
   // `OutputSinkVTable` slots so `bun_core` stays T0 (no `bun_sys` dep).
