Read a file from the local filesystem.
ReadRead any file from the local filesystem. Supports text, images, PDFs (up to 20 pages per request), and Jupyter notebooks with line numbers.
Instructions
Reads a file from the local filesystem. You can access any file directly by using this tool. Assume this tool is able to read all files on the machine. If the User provides a path to a file assume that path is valid. It is okay to read a file that does not exist; an error will be returned.
Usage:
The file_path parameter must be an absolute path, not a relative path
By default, it reads up to 2000 lines starting from the beginning of the file. Files larger than 256KB will return an error; use offset and limit for larger files
When you already know which part of the file you need, only read that part. This can be important for larger files.
Results are returned using cat -n format, with line numbers starting at 1
This tool allows Claude Code to read images (eg PNG, JPG, etc). When reading an image file the contents are presented visually as Claude Code is a multimodal LLM.
This tool can read PDF files (.pdf). For large PDFs (more than 10 pages), you MUST provide the pages parameter to read specific page ranges (e.g., pages: "1-5"). Reading a large PDF without the pages parameter will fail. Maximum 20 pages per request.
This tool can read Jupyter notebooks (.ipynb files) and returns all cells with their outputs, combining code, text, and visualizations.
This tool can only read files, not directories. To read a directory, use an ls command via the Bash tool.
You will regularly be asked to read screenshots. If the user provides a path to a screenshot, ALWAYS use this tool to view the file at the path. This tool will work with all temporary file paths.
If you read a file that exists but has empty contents you will receive a system reminder warning in place of file contents.
