Build Fix

Systematically diagnoses build and compilation failures by identifying root cause rather than symptoms, then applies targeted fixes.

Purpose

Systematically diagnose build and compilation failures by identifying root cause rather than symptoms, then apply targeted fixes that resolve the error without masking it.

Trigger

Apply when the user reports:

• "build fails", "compilation error", "can't build", "build error", "build broken"
• "linker error", "type error at build time"
• "建置失敗", "編譯錯誤", "build 出錯", "無法編譯"

Do NOT trigger for:

• Runtime errors or test failures — use debug instead
• Linting warnings that do not block the build
