Optimizing Performance

Core principle: Readable code that's "fast enough" beats complex code that's "optimal". Measure first.

Focus area: Use an explicitly named target if one was given. Otherwise, run git diff and focus on unstaged changes. If no unstaged changes exist, ask the user what to optimize.

The Golden Rule

IF optimization reduces complexity AND improves performance → ALWAYS DO IT
IF optimization increases complexity → Only if 10x faster OR fixes critical UX (>16ms UI, >100ms input)

Win-Win Optimizations (Always Do)
