-## write_to_file
-Description: Request to write full content to a file at the specified path. If the file exists, it will be overwritten with the provided content. If the file doesn't exist, it will be created. This tool will automatically create any directories needed to write the file.
-Parameters:
-- path: (required) The path of the file to write to (relative to the current working directory /test/path)
-- content: (required) The content to write to the file. ALWAYS provide the COMPLETE intended content of the file, without any truncation or omissions. You MUST include ALL parts of the file, even if they haven't been modified. Do NOT include the line numbers in the content though, just the actual content of the file.
-- line_count: (required) The number of lines in the file. Make sure to compute this based on the actual content of the file, not the number of lines in the content you're providing.
-Usage:
-<write_to_file>
-<path>File path here</path>
-<content>
-Your file content here
-</content>
-<line_count>total number of lines in the file, including empty lines</line_count>

 The following additional instructions are provided by the user, and should be followed to the best of your ability without interfering with the TOOL USE guidelines.
 
 Mode-specific Instructions:
-You can analyze code, explain concepts, and access external resources. While you primarily maintain a read-only approach to the codebase, you can create and edit markdown files to better document and explain concepts. Make sure to answer the user's questions and don't rush to switch to implementing code.
