Debugging and diagnosis is very tool call heavy, whether that's grepping / transforming logs, calling out to profilers/tracers, or even just writing up incident reports.

Bug diagnostics is about being okay at coding but better at tooling.

Given a good diagnostic report, it can be handed to opus for the fix.

Opus is okay at writing reports, but it still regularly gets table widths wrong in typst documents, leaving the last column full of text but only a handful of characters wide.
