Skills Collection

A curated collection of agent skills for Claude Code and compatible agent platforms.

CLI 工具：skills-manager

使用 skills-manager 脚本将场景中的技能通过软连接安装到各 Agent 平台的 skills 目录。

使用方式

# 列出所有可用场景
python3 skills-manager scenarios list

# 安装指定场景（将技能软连接到默认目标目录）
python3 skills-manager scenarios install Common

默认安装目标

软连接会安装到以下目录（自动创建，已存在则跳过）：

软连接清理

每次执行 install 时，脚本会自动清理目标目录中指向当前仓库、但不在当前场景配置中的无效软连接，确保安装目录保持整洁。

Quick Reference

Skill Details

agent-browser

Purpose: Browser automation CLI for AI agents.

Use Cases:

• Navigate websites and interact with pages
• Fill forms, click buttons, take screenshots
• Scrape data, test web applications
• Handle authentication flows

Key Commands:

• agent-browser open <url> — Navigate to URL
• agent-browser snapshot -i — Get interactive elements with refs
• agent-browser click @e1 / agent-browser fill @e2 "text" — Interact via refs
• agent-browser screenshot — Capture page images

brainstorming

Purpose: Collaborative design exploration before implementation.

When to Use: Before any creative work — creating features, building components, adding functionality, or modifying behavior.

Process:

1. Explore project context
2. Ask clarifying questions (one at a time)
3. Propose 2-3 approaches with trade-offs
4. Present design sections for approval
5. Write design doc to docs/superpowers/specs/
6. Invoke writing-plans for implementation

Hard Gate: Do NOT write code until design is approved.

find-skills

Purpose: Discover and install skills from the open agent skills ecosystem.

When to Use:

• "How do I do X?"
• "Find a skill for X"
• "Is there a skill that can..."

Key Commands:

• npx skills find [query] — Search for skills
• npx skills add <package> — Install a skill
• Browse: https://skills.sh/

frontend-design

Purpose: Create distinctive, production-grade frontend interfaces.

When to Use: Building web components, pages, artifacts, posters, or applications.

Design Principles:

• Bold aesthetics — Choose an extreme direction (minimalist, maximalist, retro-futuristic, etc.)
• Typography — Distinctive, characterful font choices
• Motion — Well-orchestrated animations, scroll-triggered effects
• Spatial composition — Unexpected layouts, asymmetry, overlap

Avoid: Generic AI aesthetics (Inter font, purple gradients, predictable layouts)

frontend-skill

Purpose: Ship premium, award-level interfaces with art direction and restraint.

When to Use: When quality depends on art direction, hierarchy, imagery, and motion.

Defaults:

• Start with composition, not components
• Full-bleed hero, no card grids
• Brand-first hierarchy
• Two typefaces max, one accent color
• Cardless layouts preferred

Litmus Checks:

• Is the brand unmistakable in the first screen?
• Can the page be understood by scanning headlines only?
• Would the design feel premium without decorative shadows?

pua

Purpose: High-agency problem-solving with performance coaching.

When to Use:

• User frustration or repeated failures (2+)
• Passive behavior or quality complaints
• Triggers: "try harder", "figure it out", "stop giving up", "you broke it"

Methodology Routing:

skill-creator

Purpose: Create, modify, and measure skill performance.

When to Use:

• Creating a skill from scratch
• Editing or optimizing existing skills
• Running evals to test skills
• Benchmarking skill performance

Workflow:

1. Capture intent (what, when, output format)
2. Interview and research edge cases
3. Write SKILL.md with YAML frontmatter
4. Create test cases in evals/evals.json
5. Run with-skill vs baseline subagents
6. Review, iterate, package

ui-ux-pro-max

Purpose: Professional UI/UX design for high-end work.

When to Use: Complex UI/UX projects requiring professional design expertise.

vercel-react-best-practices

Purpose: React and Next.js performance optimization from Vercel Engineering.

When to Use:

• Writing new React components or Next.js pages
• Implementing data fetching
• Reviewing code for performance
• Optimizing bundle size or load times

Rule Categories (65 rules):

web-design-guidelines

Purpose: Review UI code for Web Interface Guidelines compliance.

When to Use:

• "Review my UI"
• "Check accessibility"
• "Audit design"
• "Review UX"

Process:

1. Fetch latest guidelines from source
2. Read specified files
3. Check against all rules
4. Output findings in file:line format

writing-plans

Purpose: Write comprehensive implementation plans for multi-step tasks.

When to Use: You have a spec or requirements for a multi-step task, before touching code.

Output: Plans saved to docs/superpowers/plans/YYYY-MM-DD-<feature-name>.md

Structure:

• Bite-sized tasks (2-5 minutes each)
• Exact file paths
• Complete code in every step
• Exact commands with expected output
• DRY, YAGNI, TDD, frequent commits
