feat: MDX-backed Content Blocks (#6234)
## Summary Supersede #6182 with a clean implementation of MDX-backed Content Blocks on top of the unchanged `main` Content Block editing model. A connected `.mdx` Asset changes where authored children are loaded and saved; it must not change how Content mode inserts, edits, selects, moves, copies, or deletes instances. The previous implementation remains available in `agent/mdx-content-block-6124` and `agent/mdx-content-block-6124-review`. Reuse its independently tested parsers, converters, schemas, Asset repository, template resolution, publication, MCP, and UI work where those pieces fit the corrected architecture. Do not port its per-operation storage routing, projected editing stores, MDX undo/history, or atomic multi-root machinery. Ref #6124 Ref #6182 Closes #6261 ## Locked behavior - `.md` keeps its existing Markdown behavior; `.mdx` enables MDX. - Standard Markdown structures are stored as Markdown. JSX is used only for structures Markdown cannot represent losslessly. - Generic elements use `<ws.element ws:tag="…">`; template instances use `<ws.element ws:name="…">`. - Invalid, unsafe, or unsupported MDX never prevents editing the file or publishing the project. Builder and publication use the same recovery result: recoverable nodes are skipped with source-located warnings, while an unrecoverable document renders no authored file content in either environment. - Connecting a source never serializes existing Content Block children into the file. **Connect** removes ordinary persisted children, preserves Templates, sets `src`, and uses file content. - Disconnecting resets `src`, discards derived instances, leaves the Content Block empty, and never changes the Asset. - While connected, normal Content Block mutations update in-memory instances synchronously. Asset persistence happens afterward and never blocks rendering. - Genuine external revision conflicts use the standard reload-required flow. Rapid local edits are ordered/coalesced and must never conflict with each other. - Repeated scopes use Content Block ID plus Collection item identity. - Multiple Content Blocks may intentionally share one MDX Asset. They share one revisioned document session and edits propagate to every connected occurrence. - Missing templates show warnings/placeholders only in Builder and are skipped on published sites. ## Reuse strategy - [x] Audit all 62 original implementation commits and 5 later review/fix commits - [x] Reuse the shared Content Engine Markdown/MDX AST, parser, serializer, diagnostics, reference discovery, and tests - [x] Reuse SDK source schemas, instance-name utilities, unique template naming, and source-integrity validation - [x] Reuse template resolution/materialization and authored-tree conversion after removing storage-operation coupling - [x] Reuse revisioned Asset content repository, authorization, limits, and browser/server transport - [x] Reuse publication, document-graph, CLI, MCP, source-control UI, frontmatter UI, and E2E work where contracts remain valid - [x] Reuse tests as behavioral specifications; rewrite tests that assert the rejected projection/routing architecture - [x] Do not port per-operation MDX routing, alternate projected mutation stores, semantic reconciliation after each command, MDX Builder history/undo, atomic multi-file rollback, or canvas loading/saving UI ## Old-branch porting map — do not rewrite Before implementing any checklist batch, inspect the named implementation and tests on `agent/mdx-content-block-6124-review`. Move the implementation and its tests first; change only the boundary that conflicts with the rebuilt architecture. Do not create a second implementation under a new name. When a test encodes the rejected projected-store architecture, retain its behavioral assertion and replace only its setup. ### Already ported - `parseMarkdownAst`, `createMdxDocumentFromMarkdown`, `parseMdxDocument`, `serializeMdxDocument`, `preferMarkdownSyntax`, `discoverMdxBodyAssetReferences`, `discoverMdxAssetReferences`, and `previewMarkdownToMdxConversion` - Asset-reference, byte-stream, document-graph, Markdown, and MDX helpers included in commit `76bc388ba9` - Tests: the corresponding `packages/content-engine/src/**/*.test.ts` files already on this branch ### Port with their existing tests | Area | Functions to move or adapt | Tests to move with them | | --- | --- | --- | | Source contract and integrity | `parseContentBlockSourceProp`, `getContentBlockSource`, `isEqualContentBlockSource`, `formatContentBlockSourceIntegrityIssue`, `getContentBlockSourceIntegrityIssues`, `allocateUniqueContentBlockTemplateName` | `packages/sdk/src/content-block.test.ts`, `packages/sdk/src/schema/content-block.test.ts` | | Existing instance/name utilities | `findChildReferenceIndex`, `findParentInstanceReference`, `getInstanceName` | `packages/sdk/src/instances-utils.test.tsx` | | Template naming in mutations | `assignUniqueBlockTemplateNamesMutable`, `findBlockTemplateNameCollision`, `getSourceBackedBlockTemplateContext`, `getBlockTemplateNameConfirmation`, `getBlockTemplateInsertionIndex` | `packages/project-build/src/runtime/block.test.ts` | | Content-mode property permissions | `getContentModePropEligibility`;

replace them with one post-mutation snapshot serializer built from the reusable pure `reconcileMdxAuthoredContent` converter - `createContentBlockApplicationOperations` and the persistence-plan wrappers that route individual editing commands - Builder `$runtime*` projected stores, materialized mutation functions, alternate selector/tree helpers, pending projected-change state, and MDX-specific mutation sequences from `content-block-content.ts` - Canvas loading/saving/open-file presentation state, MDX history/undo, and atomic rollback machinery ## Implementation checklist ### 1. Preserve the `main` editing architecture - [x] Keep normal synchronous insert, text, Enter, slash menu, property, delete, move, wrap, copy/paste, selection, and focus mutations unchanged - [x] Materialize connected content through the same runtime instance interfaces used by ordinary Content Blocks - [x] Keep connected authored children in memory and exclude them from persisted build data - [x] Route persistence only after a synchronous mutation has updated the canvas - [x] Never wait for Asset loading, conversion, or saving before rendering an interaction - [x] Add no MDX-specific implementation to individual editing commands ### 2. Shared Markdown and MDX conversion - [x] Parse Markdown and the Markdown portion of MDX through one shared AST and plugin configuration - [x] Implement one shared MDX-to-instances converter and one shared instances-to-MDX converter - [x] Serialize headings, paragraphs, links, images, lists, tables, task lists, blockquotes, thematic breaks, code, emphasis, strong, strikethrough, and other supported GFM structures as Markdown - [x] Serialize only non-lossless/custom structures as Webstudio JSX - [x] Preserve nested Markdown in MDX elements, frontmatter, comments, tight/loose list semantics, code whitespace, reference links, and Asset references - [x] Omit transient empty draft paragraphs instead of emitting `<ws.element ws:tag="p" />` - [x] Preserve unsupported source text and authored metadata whenever it cannot be converted safely - [x] Add deterministic round-trip and canonical-output coverage for every supported Markdown structure ### 3. Invalid and unsafe MDX - [x] Preserve file source exactly; never silently repair or rewrite invalid source - [x] Ignore imports, exports, expressions, executable JavaScript, invalid properties, and other unsupported nodes when they can be isolated - [x] Continue rendering valid siblings and report every skipped subtree once with filename, line, and column - [x] Use the same recovery pipeline in Builder and publication so both render the same authored result for the current file revision - [x] When structural syntax prevents recovery, render no authored file content in Builder or publication instead of retaining a stale materialization - [x] Skip an unrecoverable Content Block on published sites and continue the build with a warning - [x] Keep invalid and unsafe files editable and reconnectable - [x] Enforce UTF-8, byte-size, depth, node-count, property-count, and generated-output limits with source-located diagnostics where possible ### 4. File formats and Asset creation - [x] Keep `.md` parsing and raw-HTML behavior unchanged - [x] Support creating, opening, editing, deleting, and recreating `.mdx` files through the normal text-file UI - [x] Open `.mdx` in the same editor experience as `.md` - [x] Always create an independent empty MDX Asset even when identical empty files exist - [x] Allow renaming `.md` to `.mdx` without converting or rewriting its contents; after rename, handle invalid contents through the normal MDX diagnostics and recovery pipeline - [x] Update an already-open MDX editor immediately after canvas persistence - [x] Bound read/write buffering and verify the returned Asset identity and revision ### 5. Source contracts and lifecycle - [x] Support direct Asset bindings and dynamic expression bindings - [x] Keep source mutation controls available only in Design mode; show the connected filename and **Open** action read-only in Content mode - [x] Reject duplicate source props, unsupported prop types, missing Assets, non-MDX Assets, and unauthorized Assets - [x] Analyze selected file diagnostics before confirmation without modifying the block or file; MDX syntax diagnostics do not block connection - [x] For a non-empty block, show **Abort** and **Connect** and explain that ordinary children will be replaced - [x] On connect, remove every non-template child, preserve Templates, set `src`, and materialize file content - [x] Replace disconnect handoff with normal `src` reset; discard derived content and leave the block empty - [x] Remove disconnect confirmation and conversion; resetting a repeated binding leaves every occurrence empty - [x] Switching sources validates/loads the target before replacing the usable binding and leaves both files unchanged - [x] Revalidate Asset revision and project version when confirmation is submitted - [x] Make repeated connect/disconnect operations idempotent - [x] Prevent disposed, stale, or out-of-order loads from replacing the newest source - [x] Keep loading, saving, conflict, empty-file, and open-file actions off canvas ### 6.

Scope, frontmatter, and diagnostics - [x] Scope materialized content by Content Block ID plus exact Collection-item/render context - [x] Prevent repeated instances and dynamic candidates from leaking generated IDs, template resolution, or diagnostics across scopes while sharing the underlying Asset source and revision where applicable - [x] Remove frontmatter editing from Settings; edit the exact YAML through the MDX Asset file editor - [x] Preserve the exact frontmatter source byte-for-byte during canvas body saves - [x] Route canvas body changes and complete-file editor saves through one revisioned per-Asset coordinator - [x] Show a source warning indicator in Settings and precise source-located diagnostics in the Asset editor - [x] Deduplicate repeated diagnostics without losing distinct locations - [x] Keep unresolved-template placeholders selectable and accessible only in Builder ### 10. Asset references, transfer, and integrity - [x] Discover and rewrite Asset references in frontmatter, Markdown links/images, and MDX properties - [x] Preserve Asset references while editing unrelated content - [x] Include referenced Asset and template revisions in dependency/cache identity - [x] Route referenced Assets through published URL rewriting - [x] Validate Content Block source integrity during project import, fragment/page transfer, copy/paste, build integrity, and pre-publish audit - [x] Allow multiple Content Blocks and dynamic render scopes to reference the same MDX Asset without treating the connection as an integrity error - [x] Preserve Templates when copying a connected Content Block - [x] Preserve direct and dynamic Content Block source bindings when copying or pasting within the same project - [x] When copying only one rendered Collection item, resolve that item’s current MDX Asset and replace the copied Content Block’s dynamic source with a direct binding to that same Asset - [x] When copying an entire Collection, preserve the Collection, its instances, and its dynamic source bindings - [x] Preserve the complete MDX source and frontmatter by reference; copying a connected block must not rewrite the shared file - [x] During cross-project transfer, copy every discoverable distinct bound MDX Asset and rewrite transferred bindings to the destination Assets - [x] If some cross-project dynamic candidates cannot be discovered or copied, continue with successful copies, preserve what can be represented safely, and warn about skipped candidates - [x] Revalidate source revisions and the destination project before applying a cross-project transfer - [x] If cross-project Asset creation or project insertion fails, leave the source project unchanged and clean up any newly reserved destination Asset - [x] Use the same transfer operation through Builder and MCP ### 11. Dynamic sources and publication - [x] Resolve dynamic bindings once per render/save scope - [x] Require finite, discoverable candidate sets for publication and load no unrelated MDX - [x] Warn and skip unbounded, missing, unreadable, malformed, or unsafe sources without failing the complete build - [x] Materialize only rendered Content Blocks; ignore Templates definitions and `src` on non-Content-Block instances - [x] Skip unresolved template subtrees while keeping valid siblings - [x] Include selected template styles, fonts, resources, unresolved names, and referenced Asset revisions in generated dependency output - [x] Keep draft-only MDX Assets out of publication retention ### 12.

Content-mode parity and disconnect handoff - [x] Allow keyboard reordering in Content mode through the normal move command while keeping the editable Content Block boundary - [x] Let already accepted Asset writes drain independently before resetting the source; disconnect does not load, flush, or convert the file - [x] Remove MDX-to-instance copying from disconnect - [x] Reset `src`, remove the derived tree, and leave the ordinary Content Block empty - [x] Preserve automatic text-editor focus after inserting editable content from the template menu - [x] Remove Builder frontmatter-save UI and report complete-file save failures through the Asset editor - [x] Add regression coverage for keyboard movement, disconnect teardown, source switching, insertion focus, and paragraph deletion focus restoration - [x] Run the complete six-scenario MDX Content Block Builder E2E suite ### 15. Final architecture review fixes - [x] Keep one canonical ordered pending document per Asset so shared Content Block occurrences cannot conflict with one another - [x] Merge ordered local edits from different occurrences while preserving text changes, insertions, deletions, and sibling reordering; keep external revisions on the strict reload-required path - [x] Centralize typed render-scope parsing, repeated-occurrence detection, scoped variable lookup, and dynamic Asset resolution across Canvas, Settings, source lifecycle, and copy/paste - [x] Capture the owning Asset session when a save is accepted so normal unmount/source-switch teardown cannot redirect or lose it - [x] Dispose project-owned roots, queues, caches, generations, failure state, and subscriptions when replacing the project Asset session - [x] Add regression coverage for same-Asset edits from two occurrences, same-node last-write ordering, structural reorder, insertion preservation, scoped source resolution, and project cleanup - [x] Re-run affected full unit suites, typechecks, production build, static checks, and all six MDX Content Block Builder E2E scenarios ### 16. Final persistence and transfer hardening - [x] Drain every accepted per-Asset edit before project-session teardown while retaining the owning authorization context - [x] Drain canvas serialization queues and revisioned Asset writes before pre-publish audit and publication - [x] Block publication on a queued serialization failure or Asset revision conflict - [x] Copy actual Asset bytes during cross-project paste, preserve MDX reference names, rewrite direct and Collection-backed Asset IDs, and clean up newly created Assets when insertion fails - [x] Include every resolved dynamic MDX source when copying an entire Collection and warn while preserving successful copies when individual Assets cannot be transferred - [x] Keep MDX editor save failures visible with retry and route conflicts through the standard reload-required flow - [x] Give keyboard nested reparenting the same editable Content Block boundary used by pointer movement - [x] Add regression coverage and rerun the complete Content Engine and Builder unit suites plus type, lint, formatting, package-boundary, and diff checks ## Current rebuild status - The connected Content Block now owns one complete MDX document: frontmatter feeds designed-shell bindings and the explicit Body outlet owns the authored MDX body. - Builder and published output resolve the same frontmatter document graph, including nested document references and Asset references. - Direct frontmatter text/property edits use the existing ordered per-Asset session; referenced-document values remain file-owned. - Repeated Collection occurrences keep isolated runtime shell/Body identities and occurrence-specific document values. - The local blog article layout has been upgraded to the document/Body model and its bindings validate cleanly. - Full affected package suites and typechecks pass; every new regression was demonstrated fail/pass. - `pnpm lint`, package boundaries, `pnpm oxfmt --check`, generated API/docs checks, fixture builds, and `git diff --check` pass. - Full fixture synchronization is blocked by the development API rejecting this local CLI version before fixture generation; existing fixture bundles build successfully. - Complete agent evaluations remain pending explicit approval. ### 17. Treat Content Block source as a property - [x] Declare Content Block `src` in component metadata as a Design-mode initial property labeled **Source** - [x] Add the short property description: “Create an .mdx file in Assets, then select or bind it here.” - [x] Accept only a direct Asset or an expression resolving to an Asset ID; reject URL/string sources, missing Assets, and non-MDX Assets - [x] Extract and reuse the Image-style Asset picker and binding presentation without duplicating source-control UI - [x] Render Source through the normal properties section and remove the separate source-section placement and special `src` filtering - [x] Route Source changes through Content Block connect, switch, and disconnect lifecycle operations instead of generic prop updates - [x] Keep connect confirmation, Open, diagnostics, and persistence state attached to Source; remove frontmatter and disconnect UI - [x] Add regression coverage for direct Assets, dynamic Asset bindings, invalid resolved values, lifecycle operations, and Design/Content mode visibility - [x] Re-review authoritative `docs/` content for the Source-property UI change and update it if required ### 18. Source property UX - [x] Show one full-width bindable Connect .mdx file button while disconnected - [x] Show equal-width filename and Open buttons while connected - [x] Switch files from the filename button through the source lifecycle - [x] Override PropertyLabel reset and Alt-click with the disconnect lifecycle - [x] Preserve confirmation, pending, failure, repeated-scope, and dynamic-source behavior - [x] Add regression coverage for connect, switch, binding, reset, and disconnect - [x] Update Content Block documentation - [x] Run affected tests, typecheck, lint, formatting, package boundaries, and diff checks ### 19.

Generated contracts are refreshed. Fixture synchronization remains blocked before generation because the development API rejects this local CLI version as incompatible. The checked-in bundles pass the current Protocol suite and every fixture build with the current bundle version. |

feat: Improve MCP authoring, compact output, and agent onboarding (#5883)
## Summary This improves how agents discover, author, inspect, and verify Webstudio projects while reducing unnecessary MCP context usage. ## What changed - Adds an **Agents** section to Project Settings with ready-to-run setup commands and client configuration for Claude Code, Codex, Cursor, and VS Code. - Makes large list and schema responses compact and paginated by default, with **verbose** available when complete records or diagnostics are needed. - Applies consistent compact output to assets, instances, styles, design tokens, CLI schemas, and project-session metadata. - Returns actionable expression warnings for props, resources, and Collection bindings, including unknown variables and risky render-time mutation resources. - Improves Collection expression guidance so agents can bind array items with the correct scoped variables. - Reports rendered audit outcomes explicitly as complete, partial, confirmation-required, or failed. - Expands runtime output schemas so MCP clients can validate responses reliably. - Strengthens the packaged CLI smoke workflow with a realistic seven-page stdio MCP scenario. ## Architecture - Consolidates `project-build` from 65 file-oriented entrypoints to 11 architecture-owned surfaces. - Separates the core model, contracts, runtime authoring, transfer, state, project sessions, MCP, visual tooling, persistence codecs, and authenticated server services. - Isolates Node-only JSX evaluation from browser-safe transfer utilities and authenticated server modules. - Keeps persistence codecs independent from authenticated database services, preventing unrelated module initialization. - Defines shared instance-path types once and reuses them across runtime modules. - Preserves Immer initialization through explicit package side-effect metadata. - Adds package tests that prevent a return to source-file entrypoints or generic exposure of Node-only surfaces. ## Validation - Full repository checks, tests, typechecks, generated-file checks, and fixtures - All 163 Builder test files and 2,141 tests - All 71 project-build test files and 1,794 tests - Lint and package-boundary validation - Full packed CLI release smoke test, including install, preview, agent setup, seven-page stdio MCP workflow, rendered audit, and structured commands |

fix: preserve CSS variable and gradient references on paste (#5716)
Preserve var() references in pasted gradient shorthand (css-data/parse-css.ts) When expanding shorthand properties (e.g. background), unresolved var() tokens were lost. Now they're recovered by probing each longhand with a placeholder, mapping which longhands the var belongs to, and restoring it. Fix border-(--x) Tailwind v4 syntax not recognized (tailwind.ts) borde |

fix: CSS shorthand properties not saved when value contains var() (#5688)
Shorthand properties like background: var(--color) were silently dropped when pasting into the CSS editor because the shorthand expander can't handle unresolved var() references. Fix: CSS vars from the current element's computed styles are now resolved before expanding shorthands. Inline and nested fallbacks (var(--a, var(--b))) are supported. If a var still can't be resolved, a toast error is shown instead of silently dropping the property. |

fix: add unset values to adapt tailwind breakpoints (#5303)
Ref https://github.com/webstudio-is/webstudio/issues/2651 When convert tailwind breakpoints to webstudio breakpoints our algorithm can find holes and will stop conversion. Though this will create mobile-first breakpoints which users do not expect. Here I added workaround to specify "unset" value on property when tailwind breakpoints has holes. Here's examples **sm:opacity-20** - here the hole is in the beginning, opacity: 0.2 can be defined on base breakpoint but we need to fill with something `max-width: 479` **max-sm:opacity-10 md:opacity-20** - here the holr is in the middle, we have `max-width: 479` and base breakpoint but no `max-width: 767` |

experimental: adapt tailwind to webstudio breakpoints (#5244)
Ref https://github.com/webstudio-is/webstudio/issues/2651 There is an edge case which will prevent from converting breakpoints. When there is no base breakpoint there is no value to fill with inverted space. Though it should be very rare usecase. Need to test how often it will create new breakpoints. |
