CCS Project Roadmap

Project: CCS (Claude Code Switch) Version: 2.3.0 (PowerShell 7+ & Node.js Enhancement) Last Updated: 2025-11-04 Status: Production Ready with Enhanced Cross-Platform Support


Project Overview

CCS is a lightweight CLI wrapper for instant switching between Claude Sonnet 4.5 and GLM 4.6 AI models. Built with YAGNI/KISS/DRY principles, CCS provides seamless model switching without modifying Claude settings files.

Core Value: One command, zero downtime, right model for each task.
