I had an Amiga disk image (*.adf) that I wanted to extract the files from. There are probably tools to do this but I was just starting with Claude Code, so I asked it to write a tool to extract the files by implementing the filesystem.

It took a few prompts but I know enough about FFS (the Amiga filesystem) to guide it, and it created exactly the tool I wanted.

"force multiplier of your own skills" is a great description.
