Patch Changes

• OK skill preview guidance is now framed around the three apps OK ships first-class preview support for, naming the exact in-app browser tool to drive in each so the agent opens the preview in the host's own surface instead of falling back to the system browser:

  • Claude Code Desktop → preview_start / preview_eval (the preview pane).
  • Cursor → its built-in Browser tool's Navigate action (browser_navigate, via Cursor's cursor-ide-browser). Notes that only the agent's own Navigate reaches the pane (a third-party MCP cannot push a URL in) and that a surfaced link follows Cursor's "Browser Tab" vs "Google Chrome" picker.
  • Codex desktop app → the in-app @Browser plugin (drives via tab.goto).

  The Claude Code CLI is now a clearly separate track: pure stdio, no browser — use ok open <doc> to deep-link into OK Desktop, never print/fake a browser. The Codex CLI, IDE extension, and Cloud live on this track too (web search only, no localhost browser). The underlying capability-not-host-name principle is retained so unknown hosts still route correctly.

  The runtime "no browser attached" warning (attach-preview-once) now names the same per-host paths (preview_start, in-app browser Navigate/@Browser, CLI ok open) instead of only preview_start, so the in-band recovery signal matches the bundled skill.
