Controlled Writes: Allows INSERT and UPDATE operations on non-critical tables, but only after explicit user confirmation and with strict validation.
Database Inspection: List all available tables and retrieve user statistics or basic analytics.
Use Case: An operations agent needs to check the number of new users registered in the last week. This Skill can safely query the users table to retrieve that information without risking any modifications to the database.
