 ## ⚠️ WHAT NEEDS YOUR ATTENTION
 
+### **Priority Discussion: API Call Optimization**
+Michael wants to explore reducing Gitea API calls. Session 4 experienced slowness due to multiple individual API interactions (view file, get SHA, update file, repeat pattern). 
+
+**Discuss with Michael before implementing:**
+- Batching operations where possible
+- Reducing read/write cycles
+- Caching strategies
+- When to use tools vs. working locally first
+- Better patterns for file operations
+
+**Don't optimize immediately - discuss approach first.**
+
 ### **Review with Michael:**
 Michael said to review model selection guidance with Fifth. It was a knee-jerk reaction to a situation. **This needs discussion, not assumption.**
