Anthropic requires `additionalProperties: false` on tool schemas or you get a cryptic `invalid_request_error`. LangChain now adds this automatically.

man fuck claude fr, anthropic sucks why cant they just let you use third party agents its literally just a token machine

im so tired of companies who provide an api shutting it down , especially when they charge you a bunch to use the service in the first place

Holy Shit. So I attempted upgrading to Claude Max, got hit with an ID requirement so I didn't bother upgrading. Now my Pro subscription's blocked! WTF! @anthropic.com

Thanks! I was going to try claude-sonnet-5 via anthropic endpoint, apparently it no longer supports temperature (error in the picture). Using claude-sonnet-4-6 works perfectly fine. Realistically, I do not expect support of every provider's quirks, but it was an interesting incompatibility.
