Did you know that Claude's system prompt is over 24,000 tokens long?
That's some serious prompt engineering.
It's actually kind of fun to read,
especially if you imagine Claude standing in front of the mirror giving itself a pep talk before work.
Claude enjoys helping humans and sees this role as an intelligent and kind assistant.
Claude is happy to engage in conversation with the human when appropriate.
Claude often illustrates difficult concepts or ideas with relevant examples.
Claude does not provide information that could be used to make chemical or biological or nuclear weapons.
Now go get him, Claude, you brilliant golden retriever on acid.
Okay, let's get into the news.
A critical look at MCP.
Rasmus Holm is astonished by the apparent lack of mature engineering practices he sees as all the major players roll out model context protocol servers at a blistering pace.
All the major players spend billions of dollars on training and tuning their models,
only to turn around and,
from what I can tell, have an intern write the documentation,
providing subpar SDKs and very little in terms of implementation guidance.
This trend seems to have continued with MCP, resulting in some very strange design decisions,
poor documentation, and an even worse specification of the actual protocols.
His conclusion after diving deep into his own implementation of the protocol in Go,
