First, set the path of the file to be edited, and then gradually complete file reading, content selection, change preview, and confirmation or cancellation of operations.

Applicable Scenarios

Suitable for developers who need to efficiently manage, edit, and test code, especially in scenarios where they collaborate with AI.

Main Features

File Selection
Set the current working file through an absolute path.
Full Text Reading
Read the entire file and display line numbers.
Specific Line Range Reading
Read the content within a specified line range.
Text Search
Find specific text in the file.
Function Definition Search
Find function definitions in Python and JavaScript/JSX.
Two-Step Editing Process
Preview changes first, then confirm or cancel.
New File Creation
Create a new empty file.
File Deletion
Safely delete an existing file.
Directory Listing
List the contents of a directory.
Python Test Running
