Documentation for the files_read_tool Node

Overview

The files_read_tool node is a utility tool designed for integration within the ComfyUI framework, specifically within workflows related to large language models (LLMs). It facilitates the reading and processing of files and directories from a user-specified path. This node is useful for users who want to allow their AI models to have controlled access to files and directories, enabling them to perform operations like file reading or directory exploration in a safe and structured manner.

Functionality

The node provides functionality to read files from a specified directory path. It supports various file types such as:

• Text documents (e.g., .txt, .docx)
• Spreadsheets (e.g., .xlsx, .xls)
• PDFs (e.g., .pdf)
• Programming files (e.g., .py, .js, etc.)
• Markdown files (e.g., .md)
• JSON and CSV files

The node can either return the content of a specified file or generate a file tree when a directory is specified.

Inputs

The files_read_tool node requires the following inputs:

1. folder_path: This is a string input that specifies the path to the folder you want the LLM to control. The LLM will read files or directories only within this path to ensure security and control over file access.

2. is_enable: A boolean input that determines whether the node is enabled. By default, this is set to True. When enabled, the node performs its intended function; when disabled, it does nothing.

Outputs

The node produces the following output:

• tool: This output is provided as a string in JSON-like format. It details a function named file_read, which contains:
  • A description of its purpose (reading files within the specified directory).
  • Parameters that include the file_path to be read. If a directory path is provided instead of a file, the function returns a file tree of the directory's structure.

Use Case in ComfyUI Workflows

The files_read_tool node can be seamlessly integrated into workflows within the ComfyUI interface as follows:

1. File Access Control: It ensures LLMs access only specified files or directories, maintaining user control over accessible data.

2. File Reading Automation: Automate the task of reading various file types (e.g., documents, spreadsheets) within a specific directory for analysis or processing by LLMs.

3. Secure Directory Exploration: Safely explore directory contents to provide LLMs with metadata about available files without exposing the contents of all files immediately.

Special Features and Considerations

• Security: The node is designed to restrict LLM access to only the specified path. It ensures that files and directories outside this path are not accessed without explicit permission.

• Supported File Types: The utility can handle a broad range of file types, making it versatile for different data processing tasks.

• Live Updates: The node can produce outputs in real-time, allowing users to see file contents or directory structures as they are accessed.

• Internationalization: The node can display its name in different languages based on the user's locale settings, supporting both Chinese and English.

This node is a powerful addition to any ComfyUI workflow involving LLMs, providing controlled file access and expanding the potential for AI-driven document and data interaction.
