CCS Project Roadmap

Project Overview

CCS (Claude Code Switch) is a CLI wrapper for instant switching between multiple Claude accounts and alternative models (GLM, GLMT, Kimi). The project enables developers to maintain continuous productivity by running parallel workflows with different AI models, avoiding rate limits and context switching.

Core Value Proposition

• Zero Downtime: Instant profile switching without breaking flow state
• Cost Optimization: 81% cost savings through intelligent delegation to GLM/Kimi
• Parallel Workflows: Strategic planning with Claude + cost-effective execution with GLM
• Cross-Platform: Unified experience on macOS, Linux, and Windows
