Fast Apply Overview
What is Morph for? Morph Fast Apply looks like a new edit_file tool you give your agent access to. That’s it. Claude will output lazily into this tool when it wants to make an edit. In the tools execution, the Morph API will merge the lazy edit output by Claude/Gemini/etc. into the file. If you like using Cursor - you already like the Fast Apply UX. Fast Apply is a concept used in Cursor.
