Anthropic engineer:
“95% of our engineers are using self-improving harnesses + Opus 5.5. Now everyone is building agentic systems around them.”
In 1–2 months, we’ll all be building harnesses to orchestrate self-improving agents. No more raw prompting.
In a 35-minute lecture, Anthropic engineer shows how to build a self-improving agent harness from scratch with Opus 5.5.
Worth more than a $1500 agentic course.
