I usually ask to the dev itself (eg: like i did with Degoog in my last post) otherwise i dig around to see if they made any statement and if not, i look at the contributions history, if there is any AI agent i straight up ignore (with a few exception, some are just to check PRs which i deem fine) then i check the agent.md or equivalent and look at whats written, i never go as far as checkin the code because at that point i might just be wasting my time
