# Best Cross-Agent Skills

The Skills worth installing if you switch agents are frontend-design, remotion-best-practices and composio — each verified working on Claude Code plus at least two independent third-party clients, not merely assumed to work because SKILL.md is a plain-text format. That distinction is the whole point of this page: the characteristic cross-agent failure is a Skill that loads and quietly does less, which is exactly what assumed compatibility hides.

7 Skills, ranked by composite score (https://top-agent-skills.com/about/methodology).

## The picks

### 1. frontend-design — score 92/100 (official-anthropic)

Escape generic AI-generated UIs. Forces a bold, distinctive design direction before any code is written.

- Best for: Greenfield landing pages, marketing sites, and any UI that should feel intentional rather than templated.
- Not ideal for: Ports of an existing design system — frontend-design pushes a bold direction that may overwrite established tokens.
- Publisher: Anthropic · MIT
- Verified on: claude-code, claude-ai, claude-api, cursor, codex, gemini-cli, antigravity

```bash
npx skills add github.com/anthropics/skills --skill frontend-design
```

### 2. antigravity-awesome-skills — score 65/100 (community)

1,234+ skills in one bundle. Single install across AI coding assistants.

- Best for: Teams that want a comprehensive starting set rather than picking 30 individually.
- Not ideal for: Lean setups — you will install many skills you never use.
- Publisher: Antigravity · MIT
- Verified on: claude-code, cursor, codex, gemini-cli, antigravity

```bash
npx antigravity-awesome-skills --claude
```
