Anthropic and the Runtime Harness for Persistent Agents

TL;DR Anthropic shows that the real challenge for AI agents is not starting a task, but staying coherent throughout long executions. Avoiding cognitive drift requires a runtime harness built on external memory, checkpoints, and continuous re-anchoring. The next frontier is not autonomy alone: it is cognitive continuity.
