QUESTION: static system_prompt non deterministic? (or bug)

[DavidLGoldberg]

I have a hard-coded "static' system_prompt being set in my Agent constructor (just a string).

When I run my script, logfire shows that ~25% (intermittent issue) do NOT include this system_prompt. When they're not included there's a generic agent that gets what is usually added to a "user" agent.

When it works, there is both a system (the static one of course) and a user agent.

I don't think this is a logfire issue because without the system prompt (it's very necessary in this case) the script fails very reliably via the validation. When they are included the script returns successfully.

I couldn't find anything about this in the docs. Is there a force_system_prompt="true" or something?

Reading some of the issues, I wonder if there is some message history sticking around from previous runs? I don't see any on logfire, and hope there aren't, since I'm not trying to do anything like that for this :)

Also, I should add that I'm using ollama and llama3.1:8b and the OpenAIModel
