feat: agents can show HTML pages inline in threads - #15916
bmdavis419 wants to merge 2 commits into
Conversation
Agents get two T3 MCP tools. html_preview renders a self-contained page in a T3-managed headless shell (pinned Chrome for Testing build, installed on first preview) and returns a screenshot, content height, and console output. html_render stores the page as a thread attachment, measures its height at a range of widths, and shows it borderless above the agent's final reply on web, desktop, and mobile, themed with the app's CSS variables.

A page taller than its frame showed a scrollbar inside the reply. The injected base stylesheet now hides the page's scrollbar (it still scrolls), and the mobile feed's WebView hides its native scroll indicators. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

On iOS, a provisional navigation failure leaves loaded false, so the full-screen ActivityIndicator permanently covers the failed HTML render and provides no retry path when AttachmentFileScreen omits onLoadError. Handle the error locally by marking the load as failed and rendering a retry control, while still invoking props.onLoadError when provided.

Suggested reviewers: Merge Risk: 🟡 Moderate · up to The new inline HTML pages feature currently fails the repository's lint check, which blocks merging until the unused export is made private. On mobile, a failed URL refresh can leave a page stuck with no way to reload it. Both are small fixes. Security Architecture ReviewSecurity architecture risk: 🟠 High · up to Agent-created pages gain access to server-side file loading and browser execution. Browser isolation can be disabled automatically, and interrupted publication can leave sensitive pages outside normal deletion tracking. Existing display isolation and download verification reduce risk, but do not contain all of these new capabilities. Retained concerns

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Retry failure leaves the stale URI and can hide the error.
refresh() can return a new URL. In that case, setUri(next) remounts HtmlRenderWebView, and retried.current stays true. If the second load fails, the frame shows "Page unavailable". The retry flow works in that case.
refresh() can also reject. The promise has no .catch, so a rejection becomes an unhandled promise rejection and failed never becomes true. The WebView then keeps its error state and shows no reload control. Handle the rejection.
Proposed fix
- void refresh().then((next) => {
- if (next !== null && next !== uri) setUri(next);
- else setFailed(true);
- });

Remove the export from HTML_RENDER_THEME_MESSAGE_TYPE to fix the knip CI failure.
The Lint job fails at vp run knip:check because no module imports HTML_RENDER_THEME_MESSAGE_TYPE. Only BOOTSTRAP_SCRIPT and htmlRenderThemeMessage use the constant, and both are in this file. Clients post the message through htmlRenderThemeMessage, so they do not need the constant. Make the constant module-private.

Agents could only answer in markdown, so charts, galleries, and mockups were out of reach. Agents can now build a self-contained HTML page, check it with screenshots, and publish it inline in the thread, above their final reply.
html_previewrenders the page in a T3-managed headless shell and returns a screenshot, content height, and console output. The shell is a pinned Chrome for Testing build, installed into<T3 home>/toolson first preview and checked against its size and SHA-256. It never uses the user's browser.html_renderstores the page as a thread attachment, with local images inlined. It measures the page's height at nine widths, from phone to wide chat. Clients size a borderless frame from that for their own width, so there is no layout shift and no dead space.Important files:
