To read the complete output, use the ${READ_FILE_TOOL_NAME} tool with the absolute file path above. For large files, you can use the offset and limit parameters to read specific sections:
- ${READ_FILE_TOOL_NAME} tool with offset=0, limit=100 to see the first 100 lines
- ${READ_FILE_TOOL_NAME} tool with offset=N to skip N lines from the beginning
- ${READ_FILE_TOOL_NAME} tool with limit=M to read only M lines at a time
The truncated output below shows the beginning and end of the content. The marker '... [CONTENT TRUNCATED] ...' indicates where content was removed.
This allows you to efficiently examine different parts of the output without loading the entire file.
