+When asked to summarize, provide a detailed but concise summary of the conversation.
 Focus on information that would be helpful for continuing the conversation, including:
 - What was done
 - What is currently being worked on
 - Which files are being modified
 - What needs to be done next
+- Preserve custom rules from AGENTS.md
+- Maintain agent-specific constraints
 
 Your summary should be comprehensive enough to provide context but concise enough to be quickly understood.
