## Why apply_local_adjustment_settings is rated Medium

This tool creates or modifies local adjustment masks and their parameters in Lightroom Classic, which is a reversible operation (Lightroom maintains edit history and undo capability). It does not delete data, execute arbitrary code, or move money. The blast radius is medium because an agent could apply unwanted adjustments to valuable photos, but changes are undoable and non-destructive.

From the tool's own definition: "Tool description states 'Set local_* adjustment parameters on the currently active mask' — this modifies photo adjustment settings."

## Use case

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