Anthropic’s new Fable 5 safeguards are fascinating. When the model is used for frontier LLM development, it apparently does not simply refuse or warn the user. Instead, it quietly limits its own effectiveness through techniques like prompt modification, steering vectors, and

Ask for a video the way you'd ask for the report. No repo, no setup. That's the version of AI video that non-developers will actually use. https://t.co/Z8q8tb0a7pThe HyperFrames engine leaving the terminal and becoming a Claude connector is a bigger deal than it looks.

Loops move judgment earlier; gates hold most value

this is the cleanest framing: loops move judgment earlier. the work shifts from “write the next prompt” to “define memory, tools, gates, stop rules, and review”, the gate is where most of the value lives

Loop engineering: design loops that prompt agents; unattended loops fail.

about loop engineering. everyone's saying the same thing this week. you don't prompt agents anymore, you design loops that prompt them. here's the job that loop hands right back to you. a loop running unattended is also a loop failing unattended. loop engineering takes you
