Best Claude Code Plugins

Best Claude Code Plugins

A curated list of the most useful Claude Code plugins, based on community recommendations. Install any of these with /plugin.

1. Superpowers

Great for larger projects. Helps you plan, spins up subagents for research, and actually thinks through the problem before committing to a plan.

  • Includes TDD, systematic debugging, and verification steps
  • Stops Claude from shipping broken code and claiming it works

2. Frontend Design

Makes Claude actually care about visual design. Components come out polished, not generic AI-looking.

  • Good for landing pages, dashboards, or anything user-facing where default output looks too template-y
  • Pushes toward intentional typography, spacing, and color choices instead of safe defaults

3. Code Simplifier

Run it after a feature works. Cleans up the code without breaking anything.

  • Focuses on recently modified files
  • Good for when Claude wrote something functional but messy

4. Playground

Creates interactive single-file HTML tools. Spin up a data visualizer, design explorer, or concept map in one command.

  • Self-contained, no dependencies
  • Open the file in a browser and it just works

5. Claude in Chrome

Claude can see and interact with your browser. Read pages, click buttons, fill forms, navigate tabs.

  • Debug live sites, scrape data, automate repetitive browser tasks
  • Works with your actual logged-in session — no need to handle auth separately
  • Pairs well with everything else
  • Real-world example: Clean up promotional emails in Gmail — Claude navigates your inbox, identifies promo emails, and bulk-cleans them

6. PR Review Toolkit

Suite of specialized review agents. Covers test coverage, error handling, type design, code quality, and simplification.

  • More thorough than a single pass
  • Each agent focuses on one thing and does it well

May 2026 Update — 火星狂飙’s Top 10 Skills List

A second curated list surfaced on Douyin from 火星狂飙 in early May 2026 — three months after @DeFiMinty’s original. Different angle: heavier on workflow automation and skill creation, lighter on UI polish. The overlap with the February list points to the long-tail favorites; the new entries reflect what’s emerged since.

# Skill What It Does (per the list) Existing Wiki Coverage
1 Superpowers Multi-skill bundle: brainstorming, TDD, planning. The all-rounder. (in this entry)
2 Planning with Files Split long plans into multiple files; preserve context across compaction
3 UI UX Pro Max UI/UX-focused skill bundle (the list claims many sub-skills + a curated best-practice library) See: Pretext & Refero — Tools to Fix AI’s Frontend Problem
4 Code Review Multi-agent parallel review; orchestrated reviewer agents See: Cross-Model Code Review — Why Claude Can’t Catch Its Own Bugs
5 Code Simplifier Refactor without functional change, after a feature works (in this entry)
6 Webapp Testing Playwright-based automated browser testing as a skill
7 Ralph Loop Autonomous dev loop — agent keeps iterating on a bug until fixed See: Ralph: Autonomous Development Loop for Claude Code
8 MCP Builder Scaffold for a new MCP server, with examples
9 PPTX Direct .pptx generation; handles common format edge cases See: HTML PPT Studio — AI-Powered Presentation Skill for Claude Code, Make Slides: AI-Powered Interactive Teaching Slides, open-slide — The Slide Framework Built for AI Coding Agents
10 Skill Creator Build new skills with the official template + test framework See: Claude Code Skills: Resources & Repos

Numbers and “sub-skill counts” above come from 火星狂飙’s list — they’re the creator’s framing, not independently verified.

What the Two Lists Agree On

Superpowers and Code Simplifier appear on both lists. Worth a look for any new Claude Code setup.

What’s New in May

  • Skill Creator showing up as a recommended skill is a meta-shift — building skills is itself becoming a skill.
  • Webapp Testing + MCP Builder reflect Claude Code’s expansion past pure code authoring into infrastructure and testing automation.
  • Planning with Files is a response to context-window pressure — the same need that drove the rise of /loop and subagents.

Picking from Both Lists

If you can only install 5, candidates worth trying first: Superpowers, Code Simplifier, PR Review Toolkit, Frontend Design (or UI UX Pro Max), and one of Skill Creator / MCP Builder depending on what you build.

How LearnAI Team Could Use This

  • Use Superpowers for planning larger documentation or codebase updates before editing.
  • Use Frontend Design and Playground for visual explainers, demos, and interactive learning assets.
  • Use PR Review Toolkit before publishing changes that affect shared docs or examples.

Real-World Use Cases

  • Superpowers: Plan and verify a multi-page wiki refresh.
  • Frontend Design: Polish a learner-facing demo page or dashboard.
  • Code Simplifier: Clean up generated helper scripts after they pass tests.
  • Playground: Build a one-file interactive explainer for a concept map or data workflow.
  • Claude in Chrome: Test a logged-in web workflow or clean up browser-based tasks.
  • PR Review Toolkit: Run focused review passes before merging docs or tooling changes.

Tips

  • Stack skills: Combine multiple plugins based on your workflow. Superpowers for planning, Frontend Design for UI, PR Review when done.
  • Start small: Pick one plugin and get comfortable before adding more. Once you get the hang of it, you can create your own for your workflow.
