- New skills/workflow-authoring/SKILL.md — the Workflow scripting reference (script API, resume, quality patterns, examples) moved out of the tool description into a skill
- Workflow tool description shrunk to opt-in rules + meta/pipeline example + "load the workflow-authoring skill"
- Artifact: CDN allowlist replaces the strict "self-contained only" CSP rule (cdnjs, jsdelivr, tailwind, jquery scripts; Google Fonts stylesheets); favicon required only on first publish; list shows favicon
- ListAgents wording tweak
- new Chrome browser automation section; placeholder style now [bracketed]
- Session context, Agents, and Skills nest under System prompt
- skill files gain frontmatter; add design-sync skill bundle
- one folder per skill (19 slash-menu + 2 internal), SKILL.md each
- starter-components/ holds verbatim sources for every copy_starter_component
kind; animations_v3 replaces v2
- system prompt reconciled against the live environment (ask_user, doc_page,
GitHub section, tool search)
- skills and starter-component listings link to the extracted files
First entry published on the docs page with zero lag (same day as model
release). Documents the Fable->Opus safeguards routing, Project
Glasswing / Claude Mythos Preview, and the June 12-30 export-control
suspension of Fable/Mythos.
Desktop-app variant (runs within the Claude Agent SDK) with the full tool
surface: core tools plus desktop-only families absent from the CLI capture —
ccd_session widgets, visualize, iOS Simulator, the in-app Claude_Browser
automation set, credential autofill, 1Password Environments, session
management, scheduled tasks, MCP registry, Claude in Chrome, computer use,
and the Google Calendar/Drive/Gmail connectors. Connector server names on
the desktop wire are per-connector UUIDs (mcp__{uuid}__{tool}); headings
use the readable CLI-style names instead.
