Claude Cortex
Enforces cross-model code review workflows where implementing agents never review their own code—reviews route between Claude, Codex, and Gemini with structured fallback chains. Implements progressive quality gates (implementation → independent review → remediation loops) with circuit breakers and P0/P1 escalation rules, plus automated test auditing and lint enforcement. Integrates with Claude MCP servers and includes a TUI with background skill recommendation engine using keyword matching and optional semantic analysis.

Claude Agents Library
Provides 34 production-ready agent configurations across 7 professional categories (engineering, product, marketing, design, etc.), each with detailed prompts, responsibilities, and task-specific expertise. Integrates with Model Context Protocol (MCP) patterns and includes a cost optimization matrix recommending specific Claude models for different tasks, offering documented savings up to 82% on API costs. Architecture emphasizes role-based persona consistency through detailed markdown templates covering communication style, core skills, and example prompts rather than requiring custom prompt engineering.
