Read the most recent notes from Notes.txt.
AI agents call read_notes to retrieve information from Claude File Management Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves data from a notes file without any side effects. It matches the Read category definition: retrieves or queries data with no side effects. The operation is read-only and low severity since misuse would only expose existing notes data.
From the tool's definition Tool name is 'read_notes' and description states it 'Read the most recent notes from Notes.txt' - a pure read operation with no modification, deletion, or execution of code/commands.
