Getting the most out of Opus 5.5 in Claude and Claude Code

The article explains how Opus 5.5 is designed for longer, more autonomous work in Claude and Claude Code, which can materially improve developer productivity on large migrations, audits, and multi-step engineering tasks. For CIOs and technology leaders, the strategic implication is that teams can delegate more end-to-end work to AI, but only if they update operating practices—clear definitions of done, stronger guardrails for destructive actions, and structured oversight for long-running jobs. IT organizations should expect to shift from prompting for answers to managing AI-assisted workflows with explicit policies, reusable instructions, and evidence-based validation.
