## Summary This update adds new MCP and CLI capabilities for project auditing, structured data, project-specific agent instructions, focused project search, safer bulk editing, image descriptions, font discovery, visual verification, and external registry inspection. ## New Capabilities ### Audit projects - Run a single `audit` command across accessibility, SEO, security, assets, styles, and performance. - Limit an audit to selected scopes, pages, or severity levels. - Receive stable findings with locations and suggested fixes. - Run rendered audits across desktop, mobile, and Builder breakpoint widths. - Detect horizontal overflow, broken images, oversized images, eager below-fold images, render-blocking resources, and legacy font formats. - Identify unused assets, tokens, CSS variables, local styles, and breakpoints. - Identify duplicate token declarations. - Detect accessibility issues involving names, labels, headings, landmarks, IDs, keyboard focus, ARIA, iframes, and autoplaying media. - Detect SEO issues involving titles, descriptions, language, social images, and structured data. - Detect unsafe new-tab links and write resources exposed during page rendering. ### Search an entire project - Search project text, labels, props, resources, assets, and styles through `search-project`. - Find relevant records without downloading and reparsing the full project snapshot. - Scope searches to the relevant project-data areas. ### Add validated JSON-LD - Add structured data with a dedicated JSON-LD component. - Place JSON-LD inside the page Head Slot. - Edit JSON in a purpose-built code editor. - Prevent structurally invalid JSON-LD from being saved. - Validate Schema.org types, properties, and values. - Find invalid, missing, unknown, deprecated, or incompatible structured data through the SEO audit. - Let agents discover the correct JSON-LD workflow without using page custom metadata or a generic HTML embed. ### Configure project-specific agent instructions - Add AI-agent instructions from the new **Agents** section in Project Settings. - Synchronize those instructions into a managed root `AGENTS.md`. - Update or remove the managed file automatically during project sync. - Protect existing user-owned `AGENTS.md` files from being overwritten. - Share the instructions with authenticated CLI and MCP agents. - Keep agent instructions out of publicly readable production bundles. ### Generate and manage image descriptions - Audit image assets for missing descriptions. - Let a vision-capable agent inspect each image in its rendered context. - Save generated descriptions to multiple image assets in one operation. - Mark images as intentionally decorative. - Reuse the saved asset description wherever the image is used. - Re-run the audit to verify that missing-description findings are resolved. ### Perform bounded bulk replacements - Replace matching literal text across selected pages with `replace-text`. - Replace matching fixed prop text with `replace-prop-text`. - Replace matching resource names or URLs with `replace-resource-text`. - Restrict replacements by page, instance, prop, resource, field, match mode, and maximum change count. - Leave dynamic expressions unchanged. ### Inspect element ancestry - Return an element’s direct parent in instance listings. - Request the complete ancestor chain when inspecting an element. - Understand tree placement without rebuilding the instance hierarchy from raw project data. ### Discover available fonts - List uploaded font families through `list-fonts`. - Discover available system font stacks. - Inspect font family, style, weight, format, and associated asset information before applying typography. ### Inspect external component registries - Inspect a local or remote shadcn-style registry item. - Read its description, files, dependencies, targets, and documentation. - Receive an explicit Webstudio compatibility report. - Inspect registry metadata without installing or executing external code. ### Capture generated project routes directly - Run `webstudio screenshot --path /route` against the configured project. - Generate a temporary production-style preview automatically. - Capture the requested route. - Stop the temporary preview after capture. - Avoid manually building and starting a preview for a single screenshot. ### Assert visual changes - Add expected text to screenshot comparisons. - Set maximum pixel mismatch limits. - Set minimum or maximum changed-region counts. - Assert whether overall brightness or a color channel moved in the expected direction. - Use these assertions as pass/fail evidence for visual changes. ### Require compatible CLI versions - Send the project-bundle contract version with CLI synchronization requests. - Stop incompatible CLI versions before they receive incomplete project data. - Tell users exactly how to update the CLI or run the latest version once. - Prevent older clients from silently dropping project settings. ## Upgrade Note This branch introduces a new synchronized project-bundle contract. Older CLI versions must update before synchronizing against the new API. ```sh npm install -g webstudio@latest ``` Or run the latest version once: ```sh npx webstudio@latest <command> ``` --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
SDK generation scripts
Schema.org vocabulary
Run pnpm --filter @webstudio-is/sdk build:schema-org-data to refresh
src/__generated__/schema-org-data.ts from the pinned Schema.org release and
checksummed HTTPS type and property CSV files. Upgrade the version and both
checksums together after reviewing the generated vocabulary diff.
The generated data contains vocabulary names, type inheritance, property domains and ranges, and superseded terms. Runtime validation deliberately treats vocabulary mismatches as warnings: Schema.org extensions and custom JSON-LD contexts remain valid. Structural JSON-LD errors are blocking.
This validator does not guarantee eligibility for a search-engine rich result. Search engines maintain additional type-specific requirements and quality policies that should be checked against rendered or published pages.
