For example, a few months ago I was looking to build a license detection tool, and within a few weeks with the help of Claude built a tool that was 20x better than the best open source one I found (I also open sourced mine as well: https://github.com/licensedetector/cli).
The biggest problem will be navigating through the glut of libraries that have been written in my mind -- 100 tools for the same use case, all with < 100 stars will make it hard to decide between. Also, if the user didn't write them thinking about anything other than their own use cases when releasing their library, the standard response will probably be for the agent or programmer to recreate the wheel yet again, only for their specific use case, making it now 101 tools for the same use case.
