Will It Vibe?Oversized single-file component
Part of Architecture & Best Practices, which counts for 15% of the overall score. When this check fires it deducts 4 points from that category, once per scan, no matter how many places it turns up.
What it detects
A .vue file exceeds 250 lines, which usually means one component owns too much template, logic, and style. Heuristic threshold; large components are a maintainability concern, not a correctness bug.
Why it matters
A very large single-file component usually mixes several responsibilities in one template, script, and style block, which makes it hard to read, test, and change without side effects. Big components also tend to re-render more than needed because unrelated state lives together. This is a maintainability heuristic based on a line-count threshold, not a correctness problem.
How to fix it
Break the component into smaller child components along natural seams (a list row, a form section, a toolbar), and lift shared logic into composables (Composition API) or mixins/utilities. Move large static markup into presentational subcomponents. Refactor incrementally and lean on existing tests so behavior stays the same.
