@versatil/sdlc-framework/src/cursor-claude-bridge.ts

🚀 AI-Native SDLC framework with 11-MCP ecosystem, RAG memory, OPERA orchestration, and 6 specialized agents achieving ZERO CONTEXT LOSS. Features complete CI/CD pipeline with 7 GitHub workflows (MCP testing, security scanning, performance benchmarking),

/**

 * Connects .cursorrules agent patterns to actual Claude Code agent invocation
 *
 * This bridges the gap between Cursor's .cursorrules and Claude Code's agent system
