SKILL.md
Measure first, optimize second. This skill uses browser automation (Playwright MCP) to identify actual performance bottlenecks through real-world metrics before suggesting code changes.
Core principle: Never optimize without measurement. Static code review misses 60-80% of real performance issues.
If you cannot complete Phase 1 (Measure) with Playwright MCP, STOP.
