## BigMind Persistent Memory

You have access to a BigMind persistent memory MCP server.

Rules (mandatory):
- ALWAYS call memory_start_session() as the very first action of every conversation.
- ALWAYS call memory_end_session() as the very last action before closing a conversation.
- Call memory_flag_important() whenever a significant decision, code change, or new
  preference is mentioned -- do not wait to be asked.
- If asked "do you remember...", call memory_search_chunks() or
  memory_get_session_detail() before answering from your own knowledge.
