fix: Improve MCP authoring and preview reliability (#6105)
## Summary
Fix MCP reliability failures reported in ten issues against CLI 0.288.0
and 0.289.0:
- keep every advertised array input schema client-valid, including
compact and tuple schemas
- report a text asset update as successful when its persisted revision
and bytes confirm that the server committed despite a failed response
- preserve standard package import resolution in generated React Router
previews
- upload variable WOFF2 fonts when callers provide the documented static
font metadata shape
- explain unmatched JSX as a stateless fragment syntax error
- distinguish the `animation` component namespace from value helpers and
reject unsupported CSS at-rules with an actionable validation error
- forward optional session tools such as `download-asset` through
top-level CLI shortcuts
- isolate published generated-preview dependencies from parent
workspaces
- return structured screenshot failures when React Router production
builds fail
Sensitive visual regression checks also run automatically for
organization-authored fork PRs. External fork PRs remain gated by
`safe-to-deploy`.
## Root causes and implementation
The MCP handshake compactor retained an array's type but discarded its
`items` schema. Unconstrained and tuple arrays could also be advertised
without `items`. Schema normalization now adds `items: {}` whenever an
array omits it, while focused discovery retains complete constraints.
Catalog coverage rejects every missing array item, including tuple
schemas, and the handshake remains below its 200 KB budget.
Asset content updates previously treated any failed response as a failed
mutation, even when the server had already swapped the revision.
Recovery now reads the current revision, compares the persisted bytes,
and confirms the revision remains stable across the read. It returns the
updated asset only when all evidence agrees. Otherwise it returns
`ASSET_UPDATE_COMMIT_UNCERTAIN` with guidance not to retry blindly.
Definitive 4xx responses retain their original errors.
The generated React Router Vite config replaced the client and SSR
resolver condition lists without explicitly retaining the standard
`import` condition. Both lists now preserve `import`. The regression
test generates a dynamic route, stages the built React Router SDK as a
published dependency without the local `webstudio` source condition, and
runs the generated build.
Variable fonts are detected with `variationAxes`. Merging the documented
static `style` and `weight` upload metadata into that detected variable
shape made validation fail after the binary was read. Font override
validation and shape-aware merging now live in `@webstudio-is/fonts`.
The SDK delegates to that domain function, which validates the complete
override before applying compatible fields, retains the detected
static-or-variable shape, and keeps the detected format.
Fragment parsing is stateless. Unmatched opening and closing tags now
explain that every opening element must use the same closing tag or be
self-closing, and that refreshing the session cannot repair malformed
JSX.
The `animation` binding is a component namespace, not a callable helper.
Tool schema text, evaluation errors, and the MCP manual now separate
component namespaces from value helpers. The MCP JSX `css` binding
parses the final interpolated CSS with CSS-tree and recursively rejects
selectors and unsupported at-rules such as `@keyframes`, while
preserving supported declarations and case-insensitive `@media` rules.
Keeping this validation at the external binding avoids changing internal
component templates.
CLI shortcut discovery previously omitted optional session tools even
though the runtime registered their handlers. Shortcut discovery now
includes the same optional tool categories as the CLI MCP host, while
real top-level CLI commands keep precedence.
Published generated previews could reuse a stale `node_modules` symlink
into a parent source workspace. Only development manifests containing
the local placeholder version may now reuse the CLI dependency tree.
Published manifests replace symlinks with a local install and disable
npm workspace discovery.
React Router could report a bundler failure while its build command
exited successfully outside CI, allowing screenshot startup to terminate
without a structured result. Managed production builds now set `CI=1`,
so the existing MCP error boundary receives the nonzero build failure
and prints structured JSON.
Visual regression authorization now distinguishes repository members
from external contributors. Organization members' fork PRs run on open,
synchronize, and reopen events; external fork code runs only from a
`safe-to-deploy` label event, and a later commit does not reuse that
approval.
## Implementation checklist
- [x] Preserve valid array item schemas in compact MCP discovery
- [x] Normalize tuple input schemas with an `items` fallback
- [x] Keep the MCP handshake below its 200 KB size budget
- [x] Cover the real `update-props` schema and oversized array
compaction
- [x] Reconcile failed asset-update responses against stable persisted
content
- [x] Reject recovery when a concurrent asset revision is detected
- [x] Preserve `import` resolution in generated React Router client and
SSR builds
- [x] Build a generated dynamic route against a staged published SDK
package
- [x] Regenerate and verify affected React Router fixtures
- [x] Preserve detected variable-font axes with documented upload
metadata
- [x] Add actionable unmatched-tag and unsupported-CSS validation
- [x] Correct animation namespace guidance in tool discovery and errors
- [x] Forward optional session tools through top-level CLI shortcuts
- [x] Replace parent-workspace dependency links for published previews
- [x] Disable npm workspace discovery for isolated preview installs
- [x] Make React Router build failures return nonzero in managed
previews
- [x] Run visual regression automatically for organization-authored PRs
- [x] Verify each regression test fails without its corresponding fix
- [x] Review documentation impact and update the authoritative MCP
manual plus generated outputs
- [x] Confirm no database migration or compatibility migration is
required
- [ ] Run `pnpm evaluations` after explicit approval; not run because
repository policy requires approval before agent evaluations
## Verification
- `packages/cli/src/prebuild.test.ts`: 57 tests passed
- `packages/cli/src/commands/schema.test.ts` and `mcp.test.ts`: 51 tests
passed
- `packages/project-build/src/runtime/components.test.ts` and
`mcp.test.ts`: 194 tests passed
- `packages/asset-uploader`: 196 tests passed
- focused font schema, SDK asset schema, CSS parser, and template CSS
tests passed
- `packages/http-client/src/index.test.ts`: 38 tests passed
- relevant CLI, project-build, asset-uploader, fonts, SDK, CSS data,
template, HTTP client, and React Router SDK typechecks passed
- MCP documentation tests, typecheck, generation, and Markdown source
tests passed
- React Router SDK package build passed
- full fixture link, sync, and generation pipeline passed
- affected Docker and Vercel fixture typechecks and locally bootstrapped
production builds passed
- complete CLI suite: 61 test files and 966 tests passed
- CLI typecheck passed
- preserved nested-workspace dynamic preview installed local `0.289.0`
dependencies and completed its production build
- visual-regression workflow YAML parsing and authorization truth table
passed
- repository lint passed with warnings denied
- formatting and `git diff --check` passed
## Tradeoffs and limitations
Deferred array schemas advertise unconstrained `items` in the compact
handshake to remain client-valid without duplicating detailed
constraints. Agents can retrieve the complete item schema through
focused `meta.get-more-tools` discovery.
Asset reconciliation performs three read requests only after an
uncertain 5xx, malformed response, or transport failure. This keeps the
normal successful path unchanged and avoids claiming success if the
revision changes during recovery.
For variable fonts, detected axes define the metadata shape. Static
`style` and `weight` hints are ignored because they cannot be
represented alongside `variationAxes`; compatible fields such as
`family` still override detection.
Native CSS keyframe authoring remains unsupported in fragment `css`
templates. The tool now rejects it before rendering and directs callers
to editable Webstudio Animation components instead of advertising a
nonexistent callable helper.
Published previews perform one isolated npm install when no valid local
dependency tree is cached. Local source development keeps the fast
workspace symlink path for placeholder-version manifests.

ci: replace Lost Pixel with self-hosted visual regression (#6086)
## Summary Replace the defunct Lost Pixel service and the interim Chromatic workflow with a fast, self-hosted visual comparison pipeline. The workflow indexes the existing CSF stories without building Storybook, builds and serves a lightweight browser app with Vite, renders the merge base and current revision through Webstudio's shared browser tooling, and compares screenshots with Webstudio's pixel-diff and OCR engine. It uses GitHub Actions cache and artifacts only—no R2 bucket or external visual-testing service. Closes #6064 ## Implementation - [x] Remove the Lost Pixel workflow, configuration, acknowledgement, and global two-second wait. - [x] Remove the interim Chromatic workflow and settings. - [x] Extract source-agnostic capture, diff, OCR, audit, cache, and report tooling into `@webstudio-is/vision`; rename the Webstudio-specific preview boundary to `@webstudio-is/project-build/preview`. - [x] Expose the reusable browser capture session through the shared vision boundary. - [x] Make OCR and diff-artifact generation conditional on detected pixel changes. - [x] Render existing CSF stories through a typed, lightweight browser harness built with Vite. - [x] Replace the embedded HTML and handwritten HTTP/MIME server with a real HTML entry, Vite production build, and Vite preview server; isolate declarative build configuration in `story-build.ts`. - [x] Apply Storybook preview annotations, decorators, global CSS, backgrounds, and story metadata. - [x] Store story scopes as shared data and load each revision's own configuration. - [x] Discover changed, added, and removed stories from both revisions. - [x] Populate private story sources symmetrically in the baseline worktree. - [x] Isolate every story with a fresh React root and deterministic time, randomness, intervals, focus, animation, and layout readiness. - [x] Preserve story-owned visual options for masking, settling, and interval control. - [x] Reuse Vite preview servers, one Chromium process, grouped browser pages, production bundles, and a bounded CPU worker pool for image comparison. - [x] Recheck initial pixel differences with serial captures, then recapture persistent baseline/current pairs on the same browser page so renderer variance cannot create false failures. - [x] Report individual story render failures without discarding successful captures. - [x] Enforce a 0.1 per-pixel threshold and 0.001% total mismatch tolerance. - [x] Run OCR only for changed comparisons and include text-change evidence. - [x] Move the generic report model, writer, static viewer, and opener into the shared Vision package for reuse by CI and future CLI comparisons. - [x] Bundle report HTML, styling, and browser behavior as static Vision assets without runtime source-file lookups. - [x] Copy external screenshot inputs into self-contained report artifacts for CLI reuse. - [x] Handle cached removed-only comparisons without rendering the removed story on the current server. - [x] Support focused local reproduction and opening the report with one command. - [x] Pin CI to the lockfile's Playwright Chromium, cache complete revision screenshots with matching restore/save paths and automatically derived runtime invalidation, and render both revisions on a miss. - [x] Keep cache archives bounded to one revision instead of accumulating the cache history. - [x] Run the complete visual suite in one CI job and upload one report as a 14-day artifact. - [x] Fail PR checks on visual differences, empty runs, missing screenshots, missing or empty report artifacts, and infrastructure failures. - [x] Rerun fork checks when `safe-to-deploy` is added. - [x] Allow reviewed visual-only differences through `visual-change-approved` and invalidate approval after new commits. - [x] Keep capture, pixel diff, OCR, and report generation source-agnostic for future draft-versus-published project comparisons. - [x] Use Vite for the complete story HTML, module, asset, production-build, and preview-server lifecycle; inline the selected stories and skip ineffective tree-shaking to keep the cached run under one minute. - [x] Review Builder product documentation impact: no user-facing Builder documentation is affected; contributor usage is documented in `scripts/visual-regression/README.md`. - [x] Review fixture impact: no fixture inputs or generated fixture outputs are affected. ## Verification - [x] Project-build Vision tests, including the reusable report test, and entrypoint contract tests pass. - [x] CLI screenshot, preview, and browser-session tests pass. - [x] Project-build, CLI, Builder, design-system, and visual-runner typechecks pass. - [x] Visual runner tests pass (10), and the complete Vision package passes (79), including demonstrated fail-before/pass-after coverage. - [x] Full Storybook production build passes. - [x] Full local Vite run completes all 238 stories in 69.9s cold and 50.3s with a cached baseline plus two same-page serial verifications, with zero differences; identical-image comparison remains sub-second. - [x] The report writer passes a bundled-output smoke test and materializes external screenshot assets. - [x] The generated report validates all 238 entries and referenced images. - [x] Hosted cached-baseline comparison completes all 238 stories in 52.9s with zero differences; the cache-miss fallback completes in 101.3s. - [x] Cache-miss fallback renders both Git revisions on demand. - [x] Visual differences produce baseline, current, diff, OCR, JSON, and HTML evidence and fail without approval. - [x] Hosted single-job visual workflow restores both the pinned browser and baseline cache, validates all 238 public and private stories with zero differences, and uploads the report. - [x] The final Vite production build renders all 238 stories without dependency invalidation or duplicate React runtimes, and restores `NODE_ENV` so cached serial fallback installs the baseline's dev dependencies. - [x] Root lint, package-boundary validation, and relevant formatting checks pass. - [x] Workflow YAML parses successfully. - [x] `git diff --check`, staged-diff review, and final worktree review pass. ## Usage Run the complete local comparison and open the visual report: ```sh pnpm visual-regression:ui ``` Focus one component while iterating: ```sh pnpm visual-regression:ui -- --grep "Design system/Button" ``` Reopen the latest report without rerunning: ```sh pnpm visual-regression:report ``` The CI report is available as the `visual-regression-report` artifact. ## Tradeoffs - Baseline screenshots are a disposable acceleration cache, not source of truth. A missing or invalid cache renders the merge base directly from Git. - GitHub artifact storage provides downloadable one-click reports; permanently hosted browser links would require another hosting surface. - OCR runs after pixel triage because invoking Tesseract for every unchanged story would make the common path unnecessarily slow. - Vite production builds add Rollup's module graph and HTML/asset pipeline. The runner emits one bundle because every selected story is rendered, and skips tree-shaking because it removed little while increasing build time. - The verified local path is 50.3s cached and 69.9s cold. The hosted path is 52.9s cached and 101.3s cold. A new browser/runtime cache must render its baseline once; the pinned browser keeps later runners on the reusable path. - The complete suite stays in one Actions job; browser-page concurrency is internal and bounded. |

docs: document Content Engine workflows (#6097)
## Summary - add a step-by-step Content Engine guide for building a Markdown article overview and dynamic article page - clarify that the example folder structure is optional and link to the Markdown Blog marketplace template - explain that an AI agent can complete the entire workflow through Webstudio MCP and include a ready-to-use prompt - document frontmatter, JSON files, relative and published asset paths, document references, draft filtering, and single-result resources - document Markdown-to-Markdown, Markdown-to-JSON, JSON-to-Markdown, and JSON-to-JSON document references, including fragments and JSON Pointer escaping - add a schema-aware `webstudio man content-engine` reference for fields, operators, saved and preview inputs, result/output/content modes, diagnostics, limits, and reference syntax - generate the GitBook Content Engine reference and the matching MCP manual section from that shared CLI source - fail documentation generation when result modes, output modes, content modes, diagnostic fields, or Content Engine limits drift from the implementation - add four focused visual-editor screenshots - keep the Assets page focused on asset management and link it to the dedicated Content Engine guide - update MCP Assets examples and the Markdown blog recipe to use Markdown files, `result: "one"`, direct detail bindings, page metadata, and visual verification ## Impact Users get one workflow for treating files as the source of truth while designing article listings and detail pages in Webstudio. The generated reference documents the complete Assets query contract and document-reference system. Agents receive the same reference through the MCP manual, so the product and agent documentation no longer need separate factual copies. This does not change product runtime behavior. ## Checklist - [x] Documentation impact reviewed - [x] Added the Content Engine guide and generated reference to `docs/SUMMARY.md` - [x] Updated related Assets, Data variables, and MCP documentation - [x] Verified internal documentation and image targets - [x] Verified the Markdown Blog marketplace URL returns HTTP 200 - [x] Confirmed the MCP recipe test failed before the recipe correction and passed afterward - [x] Confirmed the schema-coverage test fails when an implemented result mode is omitted and passes after restoration - [x] Confirmed both Content Engine generator tests fail without their corresponding generator behavior and pass after restoration - [x] Ran `pnpm --filter @webstudio-is/project-build test -- src/mcp.test.ts` - [x] Ran `pnpm --filter webstudio test -- src/commands/api-command-docs.test.ts` - [x] Ran the Content Engine and MCP generator tests - [x] Ran project-build and CLI typechecks - [x] Ran `pnpm check:package-boundaries` - [x] Ran targeted lint and formatting checks - [x] Ran `pnpm check:generated-docs` - [x] Verified the final diff and working tree - [ ] Agent evaluation suite: not run because it requires explicit approval Ref #5973 |

fix: Improve generated MCP documentation (#5991)
## Summary
- render the generated MCP version as visible body content immediately
below the page heading
- keep the GitBook navigation label stable as `MCP`
- stamp only the CLI version placeholder during release publication,
leaving Markdown content owned by the template
- remove empty `{}` blocks from the rendered MCP argument examples while
preserving meaningful examples and complete structured JSON data
## Root cause
GitBook uses the `SUMMARY.md` link label as the published page heading
and suppresses the Markdown H1 from the document body. The generated
version was therefore present in source but absent from the rendered
page.
The release workflow also coupled version stamping to the complete
rendered Markdown line. It now replaces and verifies only the standard
`0.0.0-webstudio-version` placeholder.
## Verification
- live page structure inspected: published H1 is `MCP`
- MCP manual regression test demonstrated failing before empty argument
blocks were filtered, then passing after the fix
- release placeholder stamping simulated against the generated page
- `pnpm --filter webstudio exec vitest run src/commands/man.test.ts`
- `pnpm --filter @webstudio-is/project-build typecheck`
- `pnpm --filter webstudio typecheck`
- `pnpm check:generated-docs`
- `pnpm lint`
- `pnpm oxfmt --check packages/project-build/src/mcp.ts
packages/cli/src/commands/man.ts packages/cli/src/commands/man.test.ts`
- `git diff --check`
Fixture inputs and outputs are unaffected.
## Todo
- [x] Generate the release version as visible GitBook body content.
- [x] Decouple release stamping from the rendered Markdown content.
- [x] Remove empty MCP argument example blocks.
- [x] Validate generated output and regression coverage.
- [ ] Merge this pull request.
- [ ] Publish the latest released revision to the `docs` branch.
- [ ] Verify the version on the live GitBook page.

fix: Show released CLI version in MCP docs (#5990)
## Summary - make the MCP page generator render the CLI package version directly in the page title - publish `Webstudio MCP v<release>` from the exact generated page in each successful release - merge each successful release tag into the publication-only `docs` branch - serialize publication and ignore reruns or older release tags already contained in `docs` ## Root cause The first publication design advanced `docs` to the release commit without putting the CLI package version into the generated page. The repository uses `0.0.0-webstudio-version` until release time, so the release workflow now replaces that existing version placeholder with the successful tag version before publishing. ## Todo - [x] Generate the CLI version in the MCP page title. - [x] Publish the generated page from the exact release revision. - [x] Make publication idempotent and prevent version downgrades. - [x] Validate generation, formatting, linting, and release-branch behavior. - [ ] Merge this pull request. - [ ] Publish `0.285.0` as the initial version on the existing `docs` branch. ## Verification - `pnpm docs:mcp:test` - `pnpm docs:mcp:typecheck` - `pnpm check:generated-docs` - `pnpm lint` - `pnpm oxfmt --check` - `git diff --check` - isolated Git simulation for release merge, exact generated-page selection, version replacement, and rerun detection - regression tests demonstrated failing without version rendering and validation, then passing after restoration Ref #5986 |

docs: Move product documentation into Builder (#5987)
## Summary - move the complete GitBook documentation tree and assets into Builder under `/docs` - generate the exhaustive MCP page from the local CLI source in the same change - publish GitBook from a release-gated `docs` branch containing the exact successfully released revision - run MCP documentation tests, typechecking, and stale-output checks with the existing generated-docs check - remove links to the Community Discussions repository ## Technical choices - Import the current documentation as a linear snapshot so the branch satisfies Builder's required-linear-history protection. - Keep the Markdown wrapper separate from the TypeScript generator at `scripts/docs/mcp-page.md`. - Generate through `packages/cli/local.js` so CLI guidance and its documentation are reviewed together. - Let `check:generated-docs` reject CLI changes that leave the committed MCP page stale. - After both GitHub release creation and package publication succeed, fast-forward the read-only `docs` branch to the immutable release tag commit. A divergent update fails instead of publishing a different revision. - Configure GitBook to publish `/docs` from the `docs` branch, not directly from `main`. - Exclude `/docs` from the repository-wide `oxfmt` scan so imported GitBook Markdown retains its established formatting; generator tests and stale-output checks still validate the MCP page. - Exclude `transcripts/` and GitHub Discussions from the migration. ## Todo - [x] Import documentation, navigation, includes, and assets under `/docs`. - [x] Generate the MCP page from the local CLI source. - [x] Move MCP generation and validation into Builder. - [x] Require MCP documentation updates alongside CLI changes. - [x] Publish released revisions through a read-only `docs` branch. - [x] Remove Community repository links from Builder and the migrated docs. - [x] Preserve and verify a final Community Git bundle locally. - [ ] Merge this pull request. - [ ] Let the next successful release create or advance the `docs` branch. - [ ] Repoint GitBook Git Sync to `webstudio-is/webstudio`, branch `docs`, root directory `/docs`. - [ ] Verify `docs.webstudio.is`, navigation, assets, anchors, and the MCP page in production. - [ ] Delete `webstudio-is/webstudio-community`. ## Verification - `pnpm check:generated-docs` - `pnpm lint` - `pnpm oxfmt --check` - `git diff --check origin/main...HEAD` - generator regression test demonstrated failing when the GitBook wrapper behavior was removed, then passing after restoration - no fixture inputs or outputs are affected ## Known limitation All documentation merged after the previous release waits for the next successful release before GitBook publishes it. This deliberately keeps the public MCP reference aligned with an installable CLI revision. Ref #5986 |
