Support multi-file read and edit for faster context and batch code changes

What feature would you like to see?

To speed up context building and code editing workflows, we propose adding support for the following features:

Multi-file Read: Ability to read multiple chunks from the same file or read multiple files in parallel, instead of sequentially processing them one by one.

Multi-file Edit: Ability to apply edits across multiple files in a single step, instead of handling each file separately.

These capabilities can significantly improve efficiency—potentially 2x or more—both in building context for tasks like code review or analysis and in performing actual code modifications.

Tools like Claude Code and Gemini CLI already support such features, and adding similar functionality would bring us on par with modern developer AI tools.

Are you interested in implementing this feature?

Happy to contribute if needed
