Description

[Bryan]

Often the exa tool will call a search and hang when it tries to read pages. We need to add better timeouts and error handling here.

firefox-beta Uplift Approval Request

• User impact if declined/Reason for urgency: These patches add the search_the_web tool to the assistant, allowing the assistant to directly answer user queries, rather than handing off to a search engine.
• Code covered by automated testing?: yes
• Fix verified in Nightly?: yes
• Needs manual QE testing?: yes
• Steps to reproduce for manual QE testing: Ask the agent a question requiring web search. The agent should respond directly -- generally also providing links to sources (although this requirement is not part of the patch).

In some cases, the agent will still hand off to the search engine, but it should mostly answer queries directly.

• Risk associated with taking this patch: low
• Explanation of risk level: Fallback behavior reverts to baseline search engine.
• String changes made/needed?: No
• Is Android affected?: no
