I’m thinking about banning Claude code at Shopify until they change their mind and read AGENTS.md and .agents/skills etc. Insisting on only reading CLAUDE.md sometimes leads to split brain problems when different team members use different tools. Just unnecessary.

“White House officials — who had heard Amodei liken the dangers of Anthropic’s technology to a nuclear bomb — were baffled when the CEO said he was unwilling to take the system down to address a known security vulnerability, the senior White House official said.”

Anthropic themselves found that vibecoding hinders SWEs ability to read, write, debug, and understand code. not only that, but AI generated code doesn’t result in a statistically significant increase in speed don’t let your managers scare you into increased productivity. show them this paper straight from Anthropic.
