Kratos Multi-Agent Orchestrator Adopts Claude Opus 5.5, Boosting Feature Pipeline Efficiency

Kratos, the specialist-agent orchestrator for Claude Code, has been realigned to run on Claude Opus 5.5—Anthropic's newly released flagship model released September 22, 2026—marking a significant upgrade in development workflow automation. Kratos coordinates a team of 19 specialized agents (including Athena for product strategy, Nemesis for adversarial code review, Hephaestus for specification writing, Ares for implementation, and Hera for alignment verification) through structured nine-stage feature pipelines that enforce quality gates and persistent memory across sessions. The shift to Opus 5.5 equips these agents with a model that performs at Claude Fable 5.1 level while running 30% faster and costing 40% less per typical workload than its Opus 5 predecessor.
