Tools & requirements

Browser and performance tooling; Chrome DevTools MCP is needed for the trace-specific workflow. Source review requires access to the target project.

Tool APIs and metric thresholds can change: retrieve current primary documentation. MCP setup and npm installation are separate actions. This package does not install tools or collect field data; local measurements are not a site-wide guarantee. Core frontmatter was adapted by BB Skills for the existing namespace directory; unchanged original SKILL.md is archived. This does not imply client execution was tested.
