How Keystile protects it
Every Letta action is checked before it runs, whether it comes from an AI tool or a workflow. 3 of its actions change data; your rules, limits and budgets decide whether each is allowed, held for a person or stopped, and it all goes into the signed record.
Use Letta with your AI assistant — safelyClaude, Cursor or ChatGPT do the work; Keystile checks every action first.
