Seven AI Coding Skills Every Solo Developer Should Install Right Now

Regarding the difference and choice between "Global" and "Project" skills:

I. Skill Classification: Global vs Project

In the Agent Skills open standard adopted by Cursor and mainstream AI coding agents (such as Claude Code), skills are explicitly divided into two installation modes: Global and Project.

Dimension	Global Skills	Project-level Skills
Installation Location	User home directory (e.g., `~/.agents/skills/`)	Project root directory (e.g., `project/.cursor/skills/` or `.agents/skills/`)
Scope	Effective across all projects and editor windows on the computer.	Effective only when the current project is open.
Sharing & Team	Cannot be shared directly via Git; colleagues must install them locally themselves.	Can be committed directly to a Git repository, team members get them out-of-the-box automatically after pulling.
Context Impact	If too many are installed, they may trigger incorrectly in unrelated projects, wasting tokens.	Trigger only when the project matches, keeping the AI context clean and focused.

Recommendation: Should I install globally or per project?

Recommend project-level installation: For skills targeting specific tech stacks or specific business logic. For example, vercel-react-best-practices (only needed for React projects), better-auth-best-practices (only needed for projects using Better Auth).
Recommend global installation: For general tools, meta-skills, and cross-project universal workflows. For example, skill-creator (a tool to help you write new skills), agent-browser (allows the AI to use a browser to go online), seo-audit (universal SEO checks).

Regarding the concern "Will I have to install them again for every new project?":

If you use project-level installation, you do need to "add" them again for a new project. However, you do not need to re-download and configure them.

Very simple one-line command: Just run npx skills add <name> in the new project, and it's done in 1 second.
Keeps things lightweight: Prevents the AI from secretly reading React best practice rules while you are working on a Python backend project, thus saving your precious tokens.

II. Preparation: Installing the Skills CLI Tool

The currently recommended management tool for the Agent Skills standard by the community and Vercel is the skills CLI, which helps us download, update, and manage these skills with one click.

In your terminal, you can invoke it directly using npx skills (the system will automatically download the required runtime environment).

Note (Pitfall Warning): When installing skills, the CLI sometimes asks whether to use Symlink or Copy. In Cursor, it is strongly recommended to choose Copy, because Cursor's compatibility with symbolic links is sometimes unstable. Choosing Copy ensures that Cursor correctly recognizes them as .cursor/rules rules.

III. Installation Command Guide for Target Skills

Below are the precise installation commands for the 7 skills you mentioned. You can choose to add -g (global installation) after the command or omit it (defaults to installing in the current project).

1. vercel-react-best-practices & 2. web-design-guidelines

Both of these skills are included in the official agent-skills repository maintained by Vercel.

Project-level installation (Recommended, for React projects):

npx skills add vercel-labs/agent-skills --skill vercel-react-best-practices
npx skills add vercel-labs/agent-skills --skill web-design-guidelines

Global installation:

npx skills add -g vercel-labs/agent-skills --skill vercel-react-best-practices
npx skills add -g vercel-labs/agent-skills --skill web-design-guidelines

3. skill-creator & 5. frontend-design

These are excellent skills officially provided by Anthropic. The former helps you generate new skills using natural language.

Project-level installation:

npx skills add anthropics/skills --skill skill-creator
npx skills add anthropics/skills --skill frontend-design

Global installation (Recommended to install skill-creator globally):

npx skills add -g anthropics/skills --skill skill-creator
npx skills add -g anthropics/skills --skill frontend-design

4. better-auth-best-practices

Official best practice skill for the well-known YC-incubated authentication framework Better Auth.

Project-level installation (Recommended, install only in projects requiring authentication):
```
npx skills add better-auth/skills --skill better-auth-best-practices
```

Global installation:

npx skills add -g better-auth/skills --skill better-auth-best-practices

6. agent-browser

Provides the AI with a real headless browser, allowing it to open web pages, log in, or capture logs by itself when handling tasks.

Global installation (Recommended, as it is a general utility tool):
```
npx skills add -g vercel-labs/agent-browser
```

7. seo-audit

A professional SEO audit and optimization suggestion skill maintained by Corey Haines.

Global installation (Convenient for performing SEO evaluations on any frontend project at any time):
```
npx skills add -g coreyhaines31/marketingskills --skill seo-audit
```

IV. How to Confirm and Use These Skills in Cursor?

Confirm Installation Results:
- If it's a project-level installation, after completion, you will find a .cursor/skills/ (or .agents/skills/) folder in the project root directory, containing each skill's SKILL.md and rule files.
- Some versions of Cursor automatically recognize and load these skills as .cursor/rules rules.
How to Trigger Usage:
- These skills usually come with Triggers. In daily conversations, when your input matches the trigger conditions, Cursor's Agent will automatically load them.
- For example: When you type "Help me refactor the performance of this React component", Cursor will automatically activate and reference the 40+ performance optimization rules in vercel-react-best-practices to make adjustments, without you needing to manually copy and paste prompts.
