This feels like a dumb question, but why doesn't Cursor implement that tool?

I built my own simple coding agent six months ago, and I implemented str_replace_based_edit_tool (https://platform.claude.com/docs/en/agents-and-tools/tool-us...) for Claude to use; it wasn't hard to do.

Maybe they want to have their own protocol and standard for file editing for training and fine-tuning their own models, instead of relying on Anthropic standard.

Or it could be a sunk cost associated with Cursor already having terabytes of training data with old edit tool.

Is the code to your agent and its implementation of "str_replace_based_edit_tool" public anywhere? If not, can you share it in a Gist?

Maybe this is a flippant response, but I guess they are more of a UI company and want to avoid competing with the frontier model companies?

They also can’t get at the models directly enough, so anything they layer in would seem guaranteed to underperform and/or consume context instead of potentially relieving that pressure.

Any LLM-adjacent infrastructure they invest in risks being obviated before they can get users to notice/use it.

They did release the Composer model and people praise the speed of it.
