Error message

Claude Web browser context no longer matches scoped UI template

What it means

Post-acquisition mismatch guard in sendClaudeWebBrowser: a retry template was found for the pool key, but after acquiring the browser context/page the prepared state (conversation or page state) no longer matches the scoped UI template captured earlier — e.g. the page navigated away, the conversation changed, or the pooled context was reused across a different session.

Solutions

1. Discard the pooled context and fall back to a fresh completion turn
2. Invalidate the stored browser template so subsequent retries re-capture it
3. Verify cookieString/account scope used for the retry matches the one that captured the template

When it happens

Trigger: Thrown at open-sse/executors/claude-web/browserTransport.ts:468 when the library encounters an invalid state.
