Claude 4.6 Opus Agent Teams Are Replacing Entire Development Workflows

Developers are reporting that Claude 4.6's multi-agent team feature has eliminated whole categories of work, from 40,000-line codebases to shipping 10,000 CCU apps in four hours. A new persistent-context tool called OneContext aims to supercharge the effect.

Anthropic's Claude 4.6 Opus, with its multi-agent team capabilities, is producing the kind of workflow disruption reports that are hard to dismiss as hype — because they're coming from individual developers describing specific, measurable results. As @abecky_jp wrote, the agent team feature effectively eliminated their work on a 40,000-line codebase: "僕がやってた仕事、本当に消えた" — "the work I was doing truly disappeared."
