Native content linting for VS Code — the Markup AI Style Agent checks your documents as you write, underlines issues inline, and fixes them with one click. Includes a findings panel and batch folder checking.
Prerequisites
To use Markup AI Lint, you need a Markup AI account. Once the extension is installed, sign in from the status bar or the Command Palette to start checking your content.
This extension isn't a stand-alone authoring tool — it works only with the Markup AI platform. To procure the Markup AI solution, please visit markup.ai/pricing.
Features
- Inline diagnostics — issues are underlined in the editor with high / medium / low risk levels
- One-click fixes — hover an issue for the explanation and apply the suggestion, or use the quick-fix lightbulb (Ctrl+. / Cmd+.)
- Status bar summary — risk summary (or quality score, when enabled) for the current document
- Folder checking — check many files at once and review results in a tree view
- Style guide picker — use your organization default or select any style guide you have access to
