File Manager Skill
This skill provides file management operations on the local system. It can open files, reveal them in the file explorer, and search for files.
⚠️ Security Note
Operations on files outside the workspace require user approval. The agent will pause and ask for confirmation before:
- Opening files outside the current project
- Revealing files in external locations
- Executing any file operations on system directories
When to Use
- User asks to "open" a document, image, or file
- User wants to "show in explorer" or "reveal in finder"
- User needs to find a file on their system
- User asks about file details (size, dates, type)
Available Commands
