Web Performance Skill

Tooling Notes

This skill relies on Chrome DevTools MCP. If the MCP server is missing, stop and ask the user to configure it.

First: Verify MCP Tools Available

Run a quick check before starting. If navigate_page or performance_start_trace is unavailable, stop and ask the user to add the MCP config.
