WHAT IT DOES

What save_memory_sql does on Baby-SkyNet

AI agents use save_memory_sql to create or update resources in Baby-SkyNet — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Baby-SkyNet environment.

WHY IT NEEDS A POLICY

Why save_memory_sql needs a policy

This tool creates and persists new data records in a SQL database. It is reversible (records can be updated or deleted by other tools like move_memory_sql). The high severity reflects that in a multi-session persistent memory system, malicious memory injection could poison Claude's understanding across multiple conversations, affect decision-making, or enable prompt injection attacks through stored data.

From the tool's definition Tool name contains 'save_memory_sql' and description states 'Eine neue Erinnerung speichern' (save a new memory) 'in der SQL Datenbank abgelegt wird' (placed in the SQL database).
