# CCS Project Roadmap
**Project:** CCS (Claude Code Switch)
**Version:** 2.1.4 (In Development)
**Last Updated:** 2025-11-03
**Status:** Active Development
---
## 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.

- ✅ Cross-platform support (macOS, Linux, Windows)
- ✅ One-line installation via curl/irm
- ✅ Auto-detection of current provider
- ✅ Git worktree and submodule support
- ✅ Enhanced GLM profile with default model variables
**Key Metrics:**
- Installation success rate: 100%
