Drafts a `lighthouserc.js` (or `budget.json`) at design time - picks Web Vitals thresholds (LCP / INP / CLS) per route based on traffic class (cached / dynamic / API-heavy / form-heavy) and the team's NFRs, plus resource-size budgets (JS / CSS / images / total bytes). Emits the config file ready for the lighthouse-perf runner. Use when starting Lighthouse coverage on a project that has no budgets yet, or when the existing budgets need a redesign.

Security
1 medium severity finding. This skill can be installed but you should review these findings before use.
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
The skill includes chromeFlags: '--no-sandbox' (SKILL.md:101), which instructs Lighthouse/Chrome to run without the sandbox (a security bypass), though it does not request sudo, modify system files, or create accounts.
