Most people install Claude Code and never touch the plugin marketplace.
BIG MISTAKE!!!
There are 5 skills every beginner should set up on day 1. All free.
Frontend Design stops Claude from building generic AI-looking interfaces.
Simplify spawns 3 agents to review and fix your code after every task.
Skill Creator generates entire skills from a workflow description, including evals to measure if your prompt changes are working.
Webapp Testing gives Claude a real browser to test your app.
MCP Builder teaches Claude to connect to any API or tool you use.
Stop using Claude Code without these.
