   Hi @onaly , Thanks for the request. To ensure the fix addresses your needs, could you share a bit more context on your specific use case and how you would prefer to configure these logging limits in your workflow?

   I reproduced the logging use case with a real InMemoryRunner and a local
   scripted model: a tool returns a long diagnostic dictionary whose error detail
   falls after the 300-character cutoff, so the console output omits the error.

   Would two keyword-only LoggingPlugin constructor options,
   max_content_length=200 and max_args_length=300, with None disabling
   truncation, fit the intended direction? I have a small patch preserving the
   current defaults, with 31 logging tests passing on Python 3.10 through 3.14 and
   a runner reproduction. I will open it as a draft for concrete review of this
   proposal, pending agreement on the API.

   @sanketpatil06 I've opened #7489 with configurable max_content_length / max_args_length options on LoggingPlugin (current defaults unchanged, None disables truncation), with tests. It replaces #7079, which closed automatically when I deleted my fork. Happy to adjust the API if you'd prefer a different shape.
