## Why captains_log_add is rated Medium

This tool creates or modifies data (journal entries) in a reversible manner. It does not retrieve data (Read), execute arbitrary code (Execute), permanently delete data (Destructive), or move money (Financial). The blast radius of misuse is minimal—an agent could only spam entries or fill the log with noise, which is easily recovered from or tolerated in a game context.

From the tool's own definition: "Tool name 'captains_log_add' and description 'Add an entry to your captain's log' indicates creation of new journal entries."

## Use case

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