Oleg Isonen 98d5c607ee feat: Improve MCP safety, context efficiency, and agent workflows (#5895)
## Summary

This combines the three reported MCP improvements into one release-ready
change:

- Safer mutation planning and confirmation for destructive operations.
- Much smaller MCP handshake and default discovery responses.
- Better agent workflows for checkpoints, multi-project work, and page
duplication.

## Safer destructive operations

- Exposes `dryRun` in MCP schemas for every local-capable mutation.
- Returns planned transactions through `meta.session.transaction`.
- Requires a two-step confirmation flow for destructive semantic
operations.
- Returns a short-lived token bound to the project, build version,
input, and exact generated patch plan.
- Rejects expired tokens, altered inputs, changed versions, and changed
plans.
- Sets `destructiveHint: true` only for operations that actually require
confirmation.
- Explicitly protects destructive operations whose names do not begin
with delete or replace, including replacing all redirects and clearing
all styles from a style source.

## Smaller, focused MCP context

- Defers oversized tool input schemas from the initial MCP handshake.
- Keeps complete focused schemas available through `meta.get_more_tools`
and CLI schema inspection.
- Makes template registry lists compact while preserving complete
payloads through focused get calls.
- Makes component summaries compact by default and supports paginated
component details.
- Replaces placeholder operation descriptions with useful command
descriptions.
- Constrains previously untyped JSON schema fields so clients can
validate inputs earlier.
- Keeps runtime output schemas compatible with strict MCP clients.

## Better agent workflows

- Allows read-only discovery and inspection while a workflow checkpoint
is awaiting acknowledgement.
- Continues blocking mutations until the checkpoint is acknowledged.
- Checks persisted checkpoints before every workflow call rather than
only the first call.
- Adds `--project` support so saved projects can be selected without
relinking the current directory.
- Isolates project sessions and checkpoints by selected project.
- Adds atomic `duplicate-page` substitutions for copied fixed text and
copied variable values.
- Prevents substitutions from modifying source content or global root
state.
- Rejects ambiguous or missing copied variables without leaving a
partial duplicate.

## Realistic agent verification

Minimal-context tests used a weak agent against the local packaged CLI
and stdio MCP:

- Planned a page deletion, stopped for explicit user confirmation,
committed the unchanged plan, and verified the page was absent.
- Tried to reuse a confirmation token with altered input; Webstudio
returned `DESTRUCTIVE_CONFIRMATION_INVALID` and preserved both pages.
- Verified compact handshake schemas and focused retrieval of the
complete oversized schema.
- Verified compact template and component discovery responses.
- Selected a saved project explicitly without relying on the directory
link.
- Verified checkpointed workflows permit reads but block mutations.
- Duplicated a London page into a Paris page with atomic text and
variable substitutions.
- Verified source content remained London, copied content became Paris,
and temporary pages were removed.

## Validation

- Project-build focused suites: 188 tests passed.
- CLI focused suites: 183 tests passed.
- Protocol focused suites: 21 tests passed.
- CLI, project-build, and protocol typechecks passed.
- Repository lint passed with zero warnings.
- Package-boundary validation passed.
- Generated runtime operation contracts were regenerated from source.
- Real local CLI/MCP tests passed against a running Builder server.

Oleg Isonen 12ad74584a feat: Improve MCP authoring, auditing, and verification (#5886)
## Summary

This improves how coding agents discover, author, verify, and audit
Webstudio projects through the CLI and MCP. The work focuses on making
agents more reliable with less context, while keeping edits semantic and
Builder-editable.

## What changes for users

- Agents can verify dynamic bindings after authoring and receive
actionable diagnostics when expressions, resources, scopes, or component
props do not line up.
- Agents can create complete resource-backed runtime UI through a
semantic operation instead of coordinating fragile low-level edits.
- MCP discovery and command output are compact by default, with
pagination and focused verbose detail when an agent needs more context.
- Asset, style, token, font, page, and component inspection provides
stronger usage context so agents can preserve the existing design
system.
- Rendered audits provide better evidence for responsive behavior,
geometry, contrast, generated-build size, and large-project runs.
- Cross-project MCP workflows can run from a manifest with explicit
mutation approval, isolated failures, resumable progress, and persistent
checkpoints.
- Project-specific agent onboarding is clearer and does not add
telemetry.
- Packaged CLI releases gain stronger smoke verification for install,
MCP startup, authoring, preview, screenshots, and audits.

## Reliability and architecture

- Runtime operation output schemas are generated from the runtime
registry and remain client-compatible.
- Project-build exports are consolidated around architectural boundaries
instead of feature-by-feature convenience entry points.
- HTTP, preview, screenshot, and project-session paths are hardened for
longer autonomous workflows.
- Craft compatibility work is read-only and provenance-aware; it does
not silently opt ordinary projects into Craft behavior.
- A minimal-context evaluation harness exercises key workflows with a
weaker model and stores bounded, privacy-safe evidence.

## Validation

- Rebased on the latest `origin/main`.
- `pnpm lint`
- Repository-wide `oxfmt --check`
- CLI typecheck and full test suite: 773 tests passed.
- Project-build typecheck and full test suite: 1,866 tests passed.
- Protocol typecheck and full test suite: 83 tests passed.
- HTTP client tests: 23 passed.
- CSS data tests: 3,620 passed, 1 skipped.
- Focused Builder tests: 67 passed.
- Package-boundary, generated API, and generated documentation checks
passed.
- Minimal-context agent evaluations passed for authenticated
resource-backed UI and design-system-aware responsive authoring.

Oleg Isonen dde30ffb54 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

Oleg Isonen d186d24501 feat: Improve MCP project audits, visual verification, and dynamic content authoring (#5874)
This update helps AI agents understand, audit, and visually verify
Webstudio projects more reliably. It also adds clearer guidance for
expressions, Collections, screenshots, and responsive rendered audits.

### Audit complete projects

- Run one `audit` command across accessibility, SEO, security, assets,
styles, and performance.
- Audit the whole project or focus on a specific page, scope, or
severity.
- Receive stable findings with locations, explanations, and recommended
fixes.
- Continue large result sets through pagination without repeating
general guidance.

### Audit the rendered website

- Build and inspect the generated website, rather than relying only on
stored project data.
- Check every static page at representative mobile, tablet, and desktop
widths.
- Use one suitable viewport inside each configured breakpoint range.
- Reuse the same browser and resize pages between captures for
substantially faster audits.
- Process multiple pages concurrently while keeping resource use
bounded.
- Supply concrete examples for dynamic routes such as blog posts.
- Review and confirm unusually large screenshot plans before they run.

### Find visual and performance problems

Rendered audits can detect:

- Horizontal page overflow.
- Broken images.
- Images loaded eagerly below the fold.
- Images that are much larger than their rendered size.
- Render-blocking resources.
- Legacy font formats.
- Pages that fail to load or redirect somewhere unexpected.
- Pages captured before their layout becomes stable.

Detailed screenshots, measurements, failures, and timing evidence are
saved locally for further inspection.

### Capture generated pages directly

- Capture a project route with `webstudio screenshot --path /route`.
- Automatically generate and start a temporary production-style preview.
- Stop the temporary preview after the screenshot is captured.
- Return navigation, responsive layout, and page-size evidence with JSON
output.
- Allow external image domains needed by the generated preview.

### Reuse generated previews

- Cache generated preview builds when the project has not changed.
- Reuse preview dependencies across regenerations.
- Keep preview dependencies isolated from the user’s project
dependencies.
- Surface preview build and startup failures with useful diagnostic
output.
- Include local project assets in generated previews.

### Author Collections correctly

- Explain when Collection is required for arrays and objects.
- Guide agents to bind the complete iterable instead of one item or the
response wrapper.
- Explain how Collection repeats its children for every entry.
- Explain current-item and current-key scope.
- Preserve Webstudio’s generated Collection parameters.
- Guide agents to use stable values for repeated interactive components.

### Write expressions with fewer mistakes

- Add a dedicated `webstudio://project/expressions` reference.
- Document expression scope, supported syntax, and supported methods.
- Explain how resources, variables, Collections, actions, and `system`
values are accessed.
- Distinguish fixed values from runtime expressions.
- Provide valid examples for text, props, resource URLs, headers, query
parameters, and bodies.
- Warn agents that valid syntax does not guarantee that runtime data has
the expected shape.

### Improve agent discovery

- Make Collection and expression workflows discoverable through
`meta.guide`.
- Return Collection-specific instructions through `components.get`.
- Point relevant command schemas to the expression reference.
- Keep detailed guidance available without placing it in every tool
response.

### Improve audit reliability

- Report which rendered captures passed, found issues, failed, or were
skipped.
- Distinguish planning, preview, capture, and cleanup failures.
- Include actionable retry instructions with rendered failures.
- Preserve completed evidence when part of an audit fails.
- Detect stale or conflicting preview servers more clearly.
- Support cancellation and bounded capture timeouts.

### Improve packaged CLI verification

- Add a release-shaped CLI smoke test.
- Install the packed CLI in an isolated temporary project.
- Fail on peer-dependency warning floods.
- Verify preview, screenshots, MCP calls, rendered audits, and generated
assets.
- Confirm that generic React Router previews do not include Docker-only
image dependencies.
- Keep CLI and MCP stdout machine-readable while progress remains on
stderr.

## User Impact

Agents can now audit a real rendered Webstudio site, inspect responsive
behavior, find concrete visual and performance problems, and provide
evidence for their conclusions. They also receive much clearer
instructions when turning API data into repeated content or writing
dynamic expressions.

Oleg IsonenandClaude Fable 5 071a4d9a85 feat: MCP update 3 (#5864)
## 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>
```
