[Error Assistant Response]
Based on the stack trace provided, here's my diagnosis:

## 1) Most likely root cause
This appears to be a test failure in the Error Assistant functionality within the Origen application's test suite. The exception is occurring at line 147 of the error_assistant_spec.rb file during RSpec test execution, suggesting either a test assertion failure or an unhandled exception within the Error Assistant feature being tested.

## 2) Suggested fix steps
• Check the specific test at line 147 in `spec/error_assistant_spec.rb` to understand what functionality is being tested
• Run the test with verbose output (`rspec --format documentation`) to see the actual error message and test description
• Verify that any dependencies or mock objects required by the Error Assistant are properly set up in the
  live test: raises and requests a real solution (manual)

As a general question, is it worth adding origen_llm to the gemspec for application usage too? Or is this intended for just the core at this time?

[priyavadan]

fair call, good catch. It should be in the gemspec. I've updated it.

This is a nice feature! Any web docs update needed?
