⭐ 122K stars · 10K forks — github.com/obra/superpowers
Superpowers forces Claude to plan before it writes a single line of code. It runs the full engineering loop — research, spec, plan, test, then build — so the agent stops guessing and starts reasoning like a senior developer. It's the strongest pick for complex features and multi-step agentic work.
⭐ 116K stars · 15.1K forks — github.com/affaan-m/everything-claude-code
A complete performance system for Claude Code: sharper context handling, faster task execution, a library of pre-built skills, and security-first defaults. It reaches beyond Claude Code too — supporting Codex, OpenCode, and Cursor — so a single install tightens up the whole workflow.
⭐ 54K stars · 5.2K forks — github.com/nextlevelbuilder/ui-ux-pro-max-skill
Left to its own devices, Claude builds the same landing page every time — Inter font, purple gradient, grid of cards. This skill forces a deliberate design direction before any code is written, turning typography, color systems, and animation into intentional choices rather than defaults.
⭐ 42.3K stars · 3.2K forks — github.com/thedotmack/claude-mem
Claude-Mem gives Claude persistent memory across sessions. It captures what happens as you work, compresses it with AI, and feeds the relevant context back the next time you sit down — so you stop re-explaining your codebase from scratch in every new chat.
⭐ 16.9K stars · 2.9K forks — github.com/czlonkowski/n8n-mcp
