📝 Walkthrough

The pull request adds Explorer event logging and design-token support, a Tag Mode loader for browser builds, and MCP frame-link support. It also updates CLI schemas, tests, release notes, and documentation.

Changes: Explorer event tools

Layer / File(s) Summary
Event colors and code-token rendering
apps/explorer/design/*, apps/explorer/src/design/*, apps/explorer/STYLE.md, apps/explorer/AGENT.md, .changeset/explorer-on-event.md
Adds the on-event color token and contrast checks. Moves code-token types, rendering, and styles into shared design components and updates visualization imports.
Shared copy state
apps/explorer/src/design/components/atoms/InstallCommand.tsx, apps/explorer/src/design/components/atoms/useCopy.ts, apps/explorer/src/styles/components/design/_install-command.scss, apps/explorer/src/styles/components/design/_visually-hidden.scss
Adds useCopy with idle, done, and failed states. InstallCommand uses the hook, and its visually-hidden status styles use a shared Sass mixin.
EventLog component
apps/explorer/src/design/components/molecules/EventLog.tsx, apps/explorer/src/design/components/molecules/EventLog.stories.tsx, apps/explorer/src/design/components/molecules/__tests__/*, apps/explorer/src/styles/components/design/_event-log.scss
Adds EventLog event and record types, newest-first rows, selection, Fields and JSON views, copy controls, empty-state handling, styles, stories, and tests.
Demo iframe event capture
website/src/pages/demos/_DemoFrame.tsx, website/src/pages/demos/index.tsx
Captures cloned events from demo iframes, retains up to 200 records, and displays them in EventLog. Clearing the log resets its records, selection, and sequence numbers. The frame also provides a conditional Tag Mode control.

Tag Mode loader

Layer / File(s) Summary
Core loader and script injection
packages/core/src/moin.ts, packages/core/src/inject-script.ts, packages/core/src/preview.ts, packages/core/src/index.ts, packages/core/src/__tests__/*
Adds moin activation and message validation, plus shared asynchronous script injection with integrity handling. Preview artifact loading now uses injectScript.
CLI browser entry generation
packages/cli/src/commands/bundle/*, packages/cli/src/schemas/build-manifest.ts, packages/cli/src/__tests__/unit/bundle/*
Browser entries invoke moin before flow startup. Wrap options accept a validated optional target, and generated core imports resolve from the CLI installation.
WalkerJS integration and loader documentation
apps/walkerjs/src/*, apps/walkerjs/package.json, skills/walkeros-using-cli/*, website/docs/core/index.mdx, website/docs/getting-started/quickstart/walkerjs.mdx, .changeset/tag-mode-loader.md
walker.js calls moin during initialization. Tests check loader behavior and built bundle contents. Documentation describes loader activation, target configuration, storage, and CSP conditions.

Frame links

Layer / File(s) Summary
Frame link schemas and wire types
packages/cli/openapi/spec.json, packages/cli/src/types/api.gen.d.ts, packages/mcps/mcp/src/tool-client.ts, .changeset/frame-links.md
Defines FrameLink and updates frame schemas and wire types to use links and nullable variantSetId in place of parent, placement, and inheritance fields.
MCP frame reads and link hints
packages/mcps/mcp/src/tools/*, packages/mcps/mcp/src/surface.json, packages/mcps/mcp/src/__tests__/*, packages/mcps/mcp/src/index.ts, packages/cli/src/commands/frames/index.ts, packages/cli/src/__tests__/unit/commands/frames.test.ts, website/docs/apps/mcp.mdx
Frame reads serialize links and variant-set IDs, and get uses a follow-links hint when links are present. Tests and documentation describe link fields and page-scoped frame results.

The demos page can show Tag Mode as active when no script was loaded. This is a bounded UI issue; fix it or accept it as follow-up before merging.

Ignore the Tag Mode toggle while FailedNotice is shown.

BrowserFrame renders its actions independently of its viewport children. When status === 'failed', the viewport contains FailedNotice, so frame.current is null while the Tag Mode button remains clickable. toggleTagMode then sets tagMode to true without loading the script. The button reports an active state incorrectly.

The initial mount does not create this state: the action is unavailable while isBrowser is false, and the initial loading render includes the iframe before a user can click.

🐛 Suggested fix
-    setTagMode(true);
-    if (frame.current) loadTagMode(frame.current, failTagMode);
+    if (!frame.current) return;
+    setTagMode(true);
+    loadTagMode(frame.current, failTagMode);
