Closes#6306
## Outcome
Content Block templates are now the public component model for MDX
authoring.
- Standard Markdown resolves through matching Content Block templates.
- PascalCase JSX resolves to a named template first, then to a
registered component.
- Adding or changing a template immediately affects matching MDX,
including content authored before that template existed.
- Every supported standard MDX element is present in new Content Blocks
by default.
- Template `name` is a stable PascalCase JSX identifier. `label` remains
optional display text only.
- Lowercase JSX represents native HTML and SVG without exposing
`ws.element` in authored syntax.
- Unknown, ambiguous, and unsafe JSX stays in source, produces a
source-ranged Builder diagnostic, and is omitted from published output.
- Frontmatter images preserve exact `$ref` values and use the Asset
description for `alt` text.
- Keyboard and mouse insertion from the slash menu remove the trigger
slash and preserve the selected template.
## Public MDX contract
- Markdown is canonical for standard prose.
- Lowercase JSX creates native elements:
`<section><p>Text</p></section>`.
- PascalCase JSX uses templates and registered components:
`<PromotionCard />`, `<Heading tag="h1">Title</Heading>`, and `<YouTube
src="https://youtu.be/KI5JHpzBK1s" />`.
- Component-name collisions use stable qualified identifiers such as
`Checkbox` and `RadixCheckbox`.
- A self-closing template keeps its designed default subtree. An
explicitly paired empty template clears it.
- Static quoted values and bare booleans are supported.
- Imports, exports, expressions, spreads, functions, executable
JavaScript, unsafe attributes, `<$.*>`, and authored `<ws.element>` are
rejected.
- `ws` remains only for compiler primitives with no React component.
## Implementation
- [x] Add stable, unique template names and keep them separate from
labels.
- [x] Parse and validate Markdown and JSX through their ASTs with
precise source ranges.
- [x] Share component identity between template JSX, Content MDX,
Builder materialization, reload, copy, and publication.
- [x] Resolve templates live after add, edit, rename, reorder, removal,
undo/redo, collaboration updates, and reload.
- [x] Preserve authored props, children, Asset references, template
defaults, and the exact slash-menu template choice.
- [x] Make one typed MDX semantic inventory drive default templates and
slash-menu eligibility.
- [x] Move component-dependent template assembly into the component
registry.
- [x] Replace production `$`, `animation`, and `radix` JSX namespaces
with direct component imports.
- [x] Keep only explicit compiler primitives in `ws` template JSX.
- [x] Migrate repository templates, fixtures, stories, examples, MCP
guidance, CLI guidance, and generated outputs.
- [x] Add Builder unit and Playwright coverage for authoring,
diagnostics, insertion, synchronization, reload, and publication.
- [x] Review and update the authoritative Content Block and generated
MCP documentation.
## Compatibility
- Persisted project data continues to use namespaced component IDs and
`ws:element` for generic HTML elements. No project-data migration is
required.
- Legacy `<ws.element ws:tag="…">`, `<ws.element ws:name="…">`, `<$.*>`,
`<animation.*>`, and `<radix.*>` input remains readable during the
compatibility window.
- Current serializers and repository-owned sources emit only canonical
Markdown, lowercase intrinsic JSX, or PascalCase identifiers.
- Untouched user MDX is not rewritten automatically. Legacy syntax is
canonicalized when its owning source is edited.
- Deferred follow-up: remove legacy namespace readers and proxy support
only after the canonical writer is deployed and existing projects are
backfilled. This is intentionally outside this PR.
## Verification
- [x] CI package tests, typechecks, lint, package boundaries, generated
assets, migrations, and size checks pass.
- [x] All six Builder E2E shards pass.
- [x] Fixture checks pass on Ubuntu and Windows.
- [x] Targeted local Content Engine, Template, SDK, registry, Project
Build, migration, Builder, component, CLI, and Playwright tests pass.
- [x] Runtime contracts, CLI docs, and MCP docs were regenerated from
their owning sources.
- [x] Local fixture generation completed without an unexpected fixture
diff.
- [x] Documentation impact reviewed and included in this PR.
- [x] Review and approve the intentional List visual snapshot change.
- [x] Run the complete agent evaluation suite after explicit approval.
- [x] Run the network fixture link/sync pipeline against the matching PR
deployment after explicit permission.
## Known visual change
The generated List story now targets its actual default `ul` element
instead of `ol`, so the default list styling appears in the visual
snapshot. The visual change was reviewed and the approved visual check
passes.
## Problem
Closed Collapsible Content is removed from the HTML, and the Builder
does not expose Radix’s Force Mount option.
## Solution
- Expose **Force Mount** as a boolean on Collapsible Content.
- Enable it for newly inserted Collapsible templates.
- Keep closed force-mounted content visually collapsed with template
styles.
- Preserve the existing Radix default for existing instances that do not
set the prop.
- Add regression coverage for the template default and generated Builder
metadata.
## Checklist
- [x] Expose the Force Mount control
- [x] Keep new Collapsible content mounted while closed
- [x] Preserve existing-instance behavior
- [x] Regenerate Collapsible prop metadata from source
- [x] Add regression coverage
- [x] Review documentation impact and update the Collapsible guide
- [x] Verify fixture inputs and outputs are not affected
## Verification
- [x] `pnpm --filter @webstudio-is/sdk-components-react-radix test` — 20
tests passed
- [x] `pnpm --filter @webstudio-is/sdk-components-react-radix typecheck`
- [x] `pnpm --filter @webstudio-is/sdk-components-react-radix build`
- [x] Targeted Oxlint and formatting checks
- [x] `git diff --check`
## Known limitations
Storybook visual verification was not run because it requires separate
approval.
Closes#6337
## Summary
Unifies frontend testing around three intentional boundaries:
- Vitest Node projects for pure and server tests
- Vitest Browser Mode with Playwright/Chromium for DOM and component
tests
- Playwright Test for Builder end-to-end workflows
The Builder no longer uses jsdom. Ordinary E2E workflows use an
automatically managed isolated `page` fixture; explicit contexts remain
only for simultaneous identities and suite-scoped setup.
## Technical choices
- Split Builder tests into one Node project and independent browser
projects so each Chromium/Vite process has a bounded workload.
- Added shared Browser Mode configuration for the affected SDK React
packages.
- Preserve the Builder's production top-window bridge ownership; Browser
Mode uses explicit test-only installation seams.
- Centralized Playwright context options and kept action/navigation
timeouts bounded.
- Validate Playwright filters before Docker, migrations, browser
installation, or Builder builds start.
- Preserve the first failed E2E attempt's report, traces, screenshots,
and videos when CI retries a shard.
- Split static checks, typechecks, CLI tests, core package tests,
browser package tests, and Builder projects into parallel CI jobs with
five-minute hard ceilings.
- Distribute Builder E2E tests across ten isolated shards with two
workers; parallel suites create unique per-worker setup data.
- Reuse color contrast DOM/canvas samples so the exhaustive theme sweep
takes about four seconds instead of timing out at 30 seconds.
- The removed cost is jsdom behavior drift, oversized serial check jobs,
and unnecessary E2E startup for empty selections. Real browser startup
and E2E environment setup remain.
## Todo
- [x] Split Builder pure/server tests from browser/component tests.
- [x] Migrate Builder DOM tests from jsdom to Vitest Browser Mode.
- [x] Migrate affected SDK React DOM tests to the shared Browser Mode
setup.
- [x] Remove jsdom annotations, dependencies, and compatibility setup.
- [x] Replace ordinary manual E2E contexts with the isolated `page`
fixture.
- [x] Keep explicit contexts only for concurrent identities and
`beforeAll` setup.
- [x] Preserve setup authentication isolation from workflow pages.
- [x] Add bounded Playwright action and navigation timeouts.
- [x] Preserve first-attempt E2E failure evidence across CI retry.
- [x] Reject empty E2E selections before expensive environment setup.
- [x] Parallelize repository checks into bounded CI shards.
- [x] Isolate parallel E2E setup data across workers.
- [x] Remove the color contrast sweep bottleneck.
- [x] Update E2E contributor documentation.
- [x] Review product documentation impact; no user-facing product docs
are affected.
- [x] Run the full repository tests and typechecks.
- [x] Run formatting, lint, package-boundary, generated-file, and
fixture checks.
- [x] Complete final correctness and simplification review.
## Verification
- `pnpm --filter @webstudio-is/builder test`
- `pnpm -r typecheck`
- `pnpm lint`
- `pnpm check:package-boundaries`
- `pnpm check:generated-api`
- `pnpm check:generated-docs`
- `pnpm fixtures`
- Design-system: 222 tests pass locally.
- Builder: all seven Vitest projects pass locally.
- The formerly slow E2E shard passes locally in 1m55s.
- Full database-backed Builder E2E execution passes in CI.
- All CI jobs pass; the slowest completed in 4m58s.
- No fixture inputs/outputs or generated files changed.
Ref #6270
## Summary
- Close Popover, Navigation Menu, Dialog, and Sheet content when an
ordinary same-context link is activated.
- Resolve nested text and icon clicks through the containing anchor.
- Keep modified clicks, downloads, empty fragments, new browsing
contexts, and Builder canvas interactions unchanged.
- Preserve Dialog focus handling, controlled Navigation Menu behavior,
and existing Navigation Menu Link dismissal.
## Technical choices
- Classify link activation once in the Radix package and share it across
overlay components.
- Handle activation on each content component so portalled content
closes its owning root without a global window listener.
- Close overlays based on link activation rather than route lifecycle,
making hash-only, current-page hash, and cross-page links consistent.
- Preserve Navigation Menu's controlled `value` contract while using
`defaultValue` only to initialize uncontrolled state.
- Resolve `_parent`, `_top`, and named targets against the anchor
document's current browsing context.
- Do not prevent the link's default behavior; native hash scrolling and
framework routing remain responsible for navigation.
## Compatibility
- No schema, migration, data, or public prop changes.
- Existing controlled and uncontrolled Navigation Menu behavior remains
intact.
- Existing Navigation Menu Link behavior remains intact.
- Generated fixture inputs and outputs are unaffected.
## Checklist
- [x] Add shared same-context link activation rules.
- [x] Apply dismissal to Popover, Navigation Menu, Dialog, and Sheet
runtime components.
- [x] Preserve Dialog focus restoration behavior.
- [x] Preserve controlled and uncontrolled Navigation Menu semantics.
- [x] Cover top-level and child browsing-context targets.
- [x] Assert native fragment navigation remains active.
- [x] Add component regression coverage and demonstrate fail/pass
behavior.
- [x] Run targeted lint, tests, type checking, declaration generation,
and package build.
- [x] Review documentation impact; no product documentation changes are
required because this restores expected navigation behavior without
changing the authoring interface.
## Verification
- `pnpm --filter @webstudio-is/sdk-components-react-radix test` — 15
tests passed.
- Regression demonstrations:
- canceling default activation failed the hash assertion;
- restoring Dialog trigger focus failed the focus assertion;
- treating all non-`_self` targets as external failed the top-level
`_parent` and `_top` assertions;
- replacing the controlled value with local state failed the controlled
Navigation Menu assertion.
- `pnpm --filter @webstudio-is/sdk-components-react-radix typecheck` —
passed.
- `pnpm --filter @webstudio-is/sdk-components-react-radix dts` — passed.
- `pnpm --filter @webstudio-is/sdk-components-react-radix build` —
passed.
- Targeted `oxlint --deny-warnings` — passed.
- `git diff --check` — passed.
## Known limitations
- Browser layout scrolling is not covered by a published-site E2E.
Component tests verify the native fragment update, overlay state, and
Dialog focus outcome directly.
Closes#6242
## Summary
This consolidates the reported MCP reliability fixes into one delivery.
- validate all inserted fragment expressions with the shared runtime
rules and reject text/expression children when component content models
require elements
- return an actionable error for unsupported existing-resource
references in JSX
- preserve siblings rendered before expression children
- accept unresolved CSS-variable shorthand expansion and eliminate
dynamic-alt/`htmlFor` audit false positives
- resolve exposed underscore MCP names during focused discovery
- omit unavailable stopped-preview fields and restart stale iterative
previews for external clients
- bound single and responsive screenshot capture, return
`SCREENSHOT_TIMEOUT`, and discard failed reusable browser sessions
- dispose previews when shared MCP runs fail or stdio clients
disconnect, including complete Windows process-tree cleanup
- resolve generated route templates from the CLI-managed preview
workspace during responsive verification
- retry a browser that exits during rendered-audit startup and report
sanitized exit diagnostics with a concrete browser-path recovery action
- materialize complete current session data before preview generation so
route order and project styles cannot collapse from missing lazy
namespaces
- always include CLI and Node.js version fields in generated issue
reports, with explicit legacy-client fallbacks
- document the updated preview and screenshot contracts and regenerate
the CLI manual
The current branch also retains the protections already present on
`main` for dry-run isolation, CSS rewrite truncation metadata,
stderr-only progress, shortcut argument forwarding, strict MCP schemas,
and refreshed conflict diagnostics.
## Technical choices
- MCP command orchestration stays in `mcp.ts`; preview port/retry
behavior lives with `mcp-preview`, and persisted checkpoint storage
lives in `mcp-checkpoint`. Each module owns its matching tests.
- Expression validation lives on the shared fragment input schema,
reuses `listFragmentExpressions`, and emits the same structured
validation issues as prop bindings, so JSX-derived and structured
fragments follow one contract across fragment, collection, and runtime
UI insertion.
- Element-child requirements come from component registry content models
during fragment insertion; no component names are hardcoded in the JSX
parser. `CollapsibleTrigger` metadata now matches its enforced `asChild`
implementation.
- Stopped preview status returns only `running: false`; unavailable
`url`, `pid`, and `mode` fields are optional and omitted from JSON.
- Explicit `preview.start` restarts a stale compatible iterative
preview; managed screenshots keep their optimized refresh path.
- Screenshot operations share one timeout utility. A single capture or
complete responsive batch is bounded after preview readiness;
lower-level CDP deadlines use the same stable error code.
- Failed managed captures close and forget their browser session. A
closed browser session cannot restart itself while cancellation is in
progress, which prevents orphaned Chromium processes.
- One ownership helper disposes one-shot and multi-project MCP hosts on
success or failure. Shared `mcp run` hosts dispose in one `finally`
boundary, long-running MCP hosts dispose on connection close, and
Windows uses `taskkill /T /F` instead of killing only the npm wrapper.
- Framework template readers receive the absolute template directory
captured from the build root, so later async work cannot redirect them
to the linked project's cwd. The same option drives cleanup for React
Router, Remix, and Vike.
- Browser startup gets one bounded retry before a rendered capture batch
fails. Persistent failures report only the exit code, signal, or spawn
error code plus the supported `WEBSTUDIO_BROWSER_PATH` recovery action;
local paths and raw browser output are not exposed.
- CLI and MCP preview share one session materializer that ensures the
canonical Builder namespace set before writing `.webstudio/data.json`.
Serialization rejects incomplete snapshots instead of converting missing
style/instance namespaces into valid-looking empty arrays, and preview
freshness records the post-materialization project version.
- The CLI injects its package version and `process.versions.node`; issue
formatting now keeps both fields visible even for legacy reports that
omit runtime metadata.
## Checklist
- [x] Add regression coverage for every changed behavior
- [x] Demonstrate new regression tests fail without the corresponding
fixes and pass with them
- [x] Run affected package test suites and typechecks
- [x] Run lint, package-boundary, and generated API checks
- [x] Review fixture impact — no fixture inputs or outputs are affected
- [x] Review documentation impact and update the authoritative MCP CLI
manual source/generated output
- [x] Run the complete local agent evaluation suite
## Verification
- `@webstudio-is/project-build`: 2,090 tests passed
- MCP asset query result modes are preserved across create, read, and
update serialization
- complete local agent evaluation suite: all 5 fixtures passed,
1,308,276 aggregate tokens
- `@webstudio-is/react-sdk`: 140 tests passed
- `@webstudio-is/template`: 43 tests passed
- `webstudio` CLI: 956 tests passed
- issue reporter: 5 targeted tests passed
- MCP host disposal regression was demonstrated failing without the
shared ownership boundary and passing with it
- relevant package typechecks passed
- `pnpm lint` passed
- `pnpm check:package-boundaries` passed
- `pnpm check:generated-api` passed
- generated-doc tests, typecheck, sync, and regeneration passed; the
aggregate clean-tree command reports the intentionally changed generated
CLI manual
- stalled single capture, stalled four-viewport capture, startup retry
across a four-viewport batch, sanitized browser-exit diagnostics,
complete preview materialization, post-refresh version tracking,
closed-session restart, Windows process-tree cleanup, and
preview-workspace regressions were demonstrated failing without their
fixes and passing with them
## Known limitations
- External `baseUrl` screenshots remain caller-owned and intentionally
do not regenerate, restart, or stop that external server.

Here dropped legacy descriptions generated with AI. All attributes are
using descriptions scraped from html spec. Though many component
properties redefine these attributes without descriptions. So to
workaround just always fall back to attributes descriptions. Covers most
cases.
Now we use html attribute for all components. Now components like Box
with already set "className" property will be migrated to "class"
attribute. This cuts ~350kB in builder scripts. Total ~1MB after
removing both html and aria attributes.
```diff
- 5036 build/client/assets/
+ 4676 build/client/assets/
```
Attributes and properties now have the following order
- component properties
- tag attributes
- global html attributes
- role
- aria attributes
Here got rid from auto namespacing meta.constraints and
meta.indexWithinAncestor to unlock using components from other sdk
packages.
Now package prefixes should be explicitly specified in meta though with
the help of proxy.
Though exports are still need to prefix automatically when install
package.
Reimplemented generate-stories command in sdk-cli
to not rely on sdk components and load metas
and templates dynamically according to files convention.
All styles use our css parser, no need to additional abstraction any
more. Theme is handwritten and contains only used stuff.
```diff
- 880 MB
+ 859 MB
```
Here avoided using variables and instead made Switch uncontrolled which
should cover most use cases where variables just complicates everything.
Checkbox already works this way.
Both checkbox and switch templates are migrated to jsx.
Here added one more description file for components `*.template.tsx`.
It is decoupled from component meta to fix the issue with some templates
like Sheet being treated as components though we don't have actual
components with this name.
Another reason is have it separately to not include builder specific
code and dependencies into CLI and published websites. Template package
is defined as optional in peer dependencies meta.
In this PR migrated only Button and List as examples. There is still not
support for data sources and styles.
Added support for text placeholders in children
