Addresses, amounts, and booking slots in AI memory may be stale. Memory can only flag that an address is needed; before acting, reread the value from the record that owns it, such as this order, and stop if they differ.
To teach AI how you work, many start by building a full knowledge base and stall on structure and tools. Start instead from the time AI got it wrong: write the fix as a specific rule, keeping only what changes next time.
