I tested over 100 Claude Code skills. These are the 5 I'd never start a project without. Each one bolts a real capability onto Claude Code: design, planning, security, restraint, and self-testing, so it behaves less like autocomplete and more like a senior teammate. Below is what each one is, why it earns its spot, and the exact install command.
