Two threads dominate today. First, agentic security is clearly not solved: an 80% bypass rate on Claude Code's auto mode is a five-alarm fire, arriving the same day Anthropic ships MHS to hook agents directly into biotech and quantum lab hardware. The blast radius of a compromised agent just got much larger. Second, the self-awareness research is quietly significant. Models that flag their own harmful outputs more accurately after misalignment suggests alignment has internal signatures we can measure. These threads will collide eventually.

Simon Willison details a newly discovered prompt injection attack that bypasses Claude Code's auto mode defenses approximately 80% of the time, raising urgent questions about agentic security.
New research shows that misaligned models consistently rate their own outputs as more harmful, and that realignment training reliably reverses this effect, suggesting models possess a form of behavioral self-awareness.
A review of Anthropic research on multiagent architectures, covering coordination failures, parallelization gains, and vulnerability discovery patterns observed in real tests.
