 == Knowledge base for alerts
-When Knowledge Base is enabled, AI Assistant receives `open` or `acknowledged` alerts from your environment from the last 24 hours. It uses these as context for each of your prompts. This enables it to answer questions about multiple alerts in your environment rather than just about individual alerts you choose to send it. It receives alerts ordered by risk score, then by the most recently generated. Building block alerts are excluded.
