Open Rules & memory. Add stable response preferences under My Personal Rules, then save them before testing. Switch to Agent Memory and correct outdated information. Save the lock state too; locking only takes effect after you save. For deeper changes, enable the advanced tabs in General settings. These switches reveal controls; they do not grant tool permissions. Open Operation Rules, edit the System Prompt, and save. Capability prompts describe behavior; the selected engine still determines which tools are available. Memory Subagent writes lets the DeepAgents memory assistant maintain Soul notes. Conversation history remains read-only; it cannot rewrite past chats. Enable Service records to let all three admin chat engines read your Services’ records. This read access does not expose records to consumers. Admin settings are not the Service configuration. Select Prompt and Profile versions in the Service; admin long-term memory is not automatically included. Start a new admin conversation to test the revised rules. Existing CLI chats may retain earlier instructions. Check the result before choosing those versions for a Service.
