setup-svelte-vitals

Derive this project's svelte-vitals.config instead of scaffolding a blank one.

Several rules ship inert: they declare options that all default empty, so until a project fills them in they examine nothing and report nothing. svelte-vitals install --client config-file writes a template with every field commented out — a form, not an answer. This skill fills the form in from what the project has already declared elsewhere (a markuplint config, an eslint-plugin-check-file config, and how its directories are actually named), measures every candidate against the real scanner, and only then writes a file.

When to use

Use when asked to set up, configure, adopt or onboard svelte-vitals, to fill in the config file, or on the first run in a project that has never used it. Also use on a project that installed svelte-vitals long ago and never configured the inert rules.
