I've been a long time fan and new to the community, but excited to be here! I'm wondering now that we have moved to agentic coding (looking forward to Corbin's video on Moltbot) it seems like the best way we can influence performance is by giving the best guidance and rules. Ive seen these most often in .md files. Does anyone have any best practices for a rules.md or agents.md file they would care to share?
