I just watched the Jake Van Cleef breakdown, and the biggest thing that stood out to me was context is key. It clicked because I have had multiple issues with hallucinations and assumptions made by Claude Code. Getting frustrated after long context sessions.
My main takeaway was to be as detailed so there are no open questions to introduce assumptions or hallucinations. The experiment at the end helped me understand why context is king.
Going forward, I'm going to utilize the folder structure template and use that as a foundation of all agents and skill I build.
