Novus UX Review
One code-observable critical issue found in two places: the typeof pendo !== 'undefined' guards claimed in the PR description are absent from the actual diff. Both bare pendo.trackAgent(...) calls can throw ReferenceError at runtime (Pendo is blocked by ad blockers and many page CSPs — a likely scenario for a browser extension audience), which would break message sending and silently drop assistant responses. No other UX concerns identified; the instrumentation design itself is sound.

[critical] The PR description says both calls are guarded with typeof pendo !== 'undefined', but neither call in the diff has that guard. This pendo.trackAgent("prompt", ...) sits directly in the handleMessageSubmit hot path — if Pendo isn't loaded (ad blockers are extremely common among the browser extension audience, and CSPs on many pages can block third-party scripts), this throws a ReferenceError and the user's message is never sent. Wrap this call: if (typeof pendo !== 'undefined') { pendo.trackAgent(...) }.

[critical] Same missing guard as the prompt call below — pendo.trackAgent("agent_response", ...) is unguarded inside onSuccess. If Pendo isn't loaded and this throws, it will interrupt the setOpenChat(...) state update that follows, meaning the assistant's reply never gets appended to the chat. The user sends a message, sees a loading state, and the response silently disappears. Add if (typeof pendo !== 'undefined') around this block.
