The body is lean pattern reference material—code snippets, prop signatures, and terse directives—with no padding or explanation of concepts Claude already knows, so every token earns its place.

It provides fully executable, copy-paste-ready examples with concrete import paths (e.g. "$lib/components/common", "$lib/components/select/Select.svelte", "lucide-svelte") and explicit prop signatures, matching the level-3 anchor.

The Svelte MCP section is a numbered sequence with an explicit feedback loop ("keep calling until no issues") and the Verifying section adds a Playwright validation checkpoint, giving clear sequencing with error-recovery.

Content is well-organized into clear sections and points only one level deep to signaled external docs ("frontend/brand-guidelines.md", "AGENTS.md") with no nested references; no bundle files exist to require further splitting.

Names the domain ("Svelte coding guidelines for the Windmill frontend") and a broad action ("writing or modifying code in the frontend directory"), but does not list multiple specific concrete actions, matching the level-2 anchor rather than the level-3 multi-action example.

It states what ("Svelte coding guidelines for the Windmill frontend") and an explicit when-trigger ("MUST use when writing or modifying code in the frontend directory"), clearly answering both required questions.

It surfaces natural niche terms ("Svelte", "Windmill frontend", "frontend directory") a user would say, but offers few variations/synonyms, so it sits at 'some relevant keywords but missing common variations' rather than broad coverage.

The scope is tightly bound to the Windmill frontend directory with Svelte-specific triggers, forming a clear niche unlikely to fire for unrelated skills.
