I Tried 100+ Claude Code Skills. These 6 Are The Best

A practical breakdown of 6 Claude Code skills and plugins worth using for real client work: Skill Creator (builds other skills from plain English), Superpowers (enforces senior-dev workflow with planning and testing), GSD (context engineering via sub-agents to prevent context rot), /review and /ultra review (built-in code review commands), Context Mode (compresses raw tool output to preserve context window), and ClaudeMem (persists knowledge across sessions via SQLite and vector search). The post also covers how to sell AI automations to businesses by focusing on outcomes like time saved and error reduction rather than the technical workflow itself.
