I mean in this specific case, it did, at your behest even. These contracts would probably be even easier to enforce than Claude-signed ones!

I disagree, in the same way that I'd disagree if you said the rollerball pen on my desk signed a contract.

They can be used by someone to sign a contract, but they cannot sign a contract themselves because they're just tools.

Your pen cannot sign a contract can purely because it doesn't have the capability to find a contract in your email, find a signature on your HD, and place that sig in the right place on that contract. If it did, then yes it would be capable of signing a contract just like Claude did in this case.

The bot had the authority - as agent. It had the ability - as the report itself shows.

> I could write dozen lines of bash that finds for PDFs, pastes an image into them and emails it to someone. That doesn't mean that bash can sign contracts

It does mean exactly that - though bash would need to get lucky with selection and positioning.
