## Why crow_create_song is rated Medium

The tool creates new data (a song entry) in a persistent store (songbook/blog post). This matches the Write category: creates or modifies data reversibly. Severity is medium because misuse could result in spam or unwanted content creation in the project management system, but the impact is localized and reversible.

From the tool's own definition: "Tool name 'crow_create_song' and description indicate creation of content ('Create a song') that is stored persistently ('stored as a blog post tagged'). This is a reversible write operation."

## Use case

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