This pull request introduces support for handling and validating file paths across multiple components of the codebase. The main changes include adding a new method to handle file paths in message_manager/service.py, updating constructors to accept file paths, and ensuring file paths are passed and validated in various functions.

Enhancements to File Path Handling:

• browser_use/agent/message_manager/service.py: Added a new method add_file_paths to handle file paths and integrate them into the message manager.

• browser_use/agent/service.py: Updated the __init__ method to accept available_file_paths and integrated this parameter into the agent's workflow. [1] [2] [3] [4] [5] [6]

Controller and Registry Updates:

• browser_use/controller/registry/service.py: Modified _create_param_model and execute_action methods to handle available_file_paths and ensure they are validated and passed correctly. [1] [2] [3]

• browser_use/controller/service.py: Updated multi_act and act methods to include available_file_paths in their parameters and ensure proper validation. [1] [2] [3] [4]

Example Script Enhancements:

• examples/custom-functions/file_upload.py: Enhanced the file upload script to validate file paths before performing actions, and added a new action to read file content. [1] [2]

These changes collectively improve the handling of file paths, ensuring they are validated and passed through various components of the system effectively.

I know this is an old commit, but why is available_file_paths part of the core system when upload file action is not?

It's coming in another PR @shyam-king, we are working on allowing the agent to handle file upload/download/re-upload all in one sequence.
