 - You can optionally specify a line offset and limit (especially handy for long files), but it's recommended to read the whole file by not providing these parameters
 - Any lines longer than 2000 characters will be truncated

+- This tool allows opencode to read images (eg PNG, JPG, etc). When reading an image file the contents are presented visually as opencode is a multimodal LLM.
 - You have the capability to call multiple tools in a single response. It is always better to speculatively read multiple files as a batch that are potentially useful. 
 - 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 like /var/folders/123/abc/T/TemporaryItems/NSIRD_screencaptureui_ZfB1tD/Screenshot.png
 - If you read a file that exists but has empty contents you will receive a system reminder warning in place of file contents.
