claude-soul vs lean-ctx

claude-soul: Claude Soul gives Claude Code persistent memory across sessions, automatically tracks user corrections with lifecycle stages, and develops improved behavioral frameworks over time. It runs entirely locally using SQLite, integrates via MCP server and hooks, and requires no cloud or API keys.; lean-ctx: lean-ctx is an open-source MCP server designed to drastically reduce LLM token costs for AI coding tools like Claude Code, Cursor, and Copilot. It achieves this by transparently compressing CLI output and file context, offering up to 99% savings and making AI coding faster, cheaper, and more effective without changing workflows.
