Axiom Build Debugging

This is a routing skill that decides which specialized tool to invoke when your iOS build breaks, tests crash, or Xcode acts strange. It branches to 16 different skills and agents depending on whether you've got SPM conflicts, zombie processes, slow compilation, crash logs to parse, or hangs to diagnose. The philosophy is solid: check environment issues (stale Derived Data, simulator problems) before debugging application code, since 90% of mysterious failures are tooling, not your Swift. It's comprehensive but feels like it could be overwhelming to navigate manually. The real value is if you trust it to route correctly, because each destination skill has focused expertise you'd otherwise have to remember exists.
