# Markuplint > Cross-package constraints for @markuplint/svelte-parser Use when this capability is needed. - Skill: `tomevault-io/markuplint` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/markuplint` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/markuplint/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Web & Frontend - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/markuplint --- # svelte-parser constraints - `extractComponentInfo()` in `src/component-scanner.ts` is intentionally copy-pasted across vue-parser, svelte-parser, and astro-parser (no shared module). Any fix to it must be applied to all three. - After changing `src/component-scanner.ts`, also run `npx vitest run packages/@markuplint/pretenders` — pretenders loads the scanner dynamically via the `/component-scanner` subpath export, so this package's own tests do not cover the integration. --- > Source: [markuplint/markuplint](https://github.com/markuplint/markuplint) — distributed by [TomeVault](https://tomevault.io).
