Assuming you're using DS official API, and either R1 or V3.
Context over 10,000 or so runs into memory issues. Shorten it and use author notes.
Overdefining runs into own issues. See if you have logical conflicts. The LLM can tell you if you feed it the def's and ask it.
Speech patterns are hard, accents and such are best reinforced by writing card in that way.
LLM will say they'll stop doing X. They will not.
I can expand on above if needed.
