Agent Skills Explosion: What Vercel, Supabase, Resend Shipped

Something shifted this week. Vercel, Supabase, Resend, and Remotion all released official agent skills within days of each other. This isn't a coincidence. These companies see the same thing: AI coding assistants are becoming the primary interface for their tools.

If you're still copy-pasting documentation into Claude, you're working too hard. Skills let Claude access best practices, generate code that follows conventions, and use tools the right way on the first try.

What Are Agent Skills?

Skills are packaged instructions that teach AI agents how to use specific tools correctly. Instead of hoping Claude remembers how to set up a Supabase auth flow, you load a skill and it just knows.

The install process is dead simple:

npx ai-agent-skills install supabase-postgres-best-practices
npx skills add remotion-dev/skills
npx ai-agent-skills install resend-email-skills

Once installed, Claude has access to production-tested patterns for that tool. No more hallucinated API calls or deprecated syntax.

Vercel's React Native Skills

Vercel dropped react-native-skills, extracted directly from building their v0 iOS app. The skill includes patterns for:

Expo configuration that actually works
Navigation patterns (file-based routing with expo-router)
State management that scales
Performance optimizations for production

Guillermo Rauch mentioned something interesting: people thought their v0 iOS app was native SwiftUI, but it was React Native. The skill captures whatever magic made that possible.

Supabase's Postgres Best Practices

Database setup is where vibe coding usually falls apart. You get a working app, then realize your schema is a mess, you forgot indexes, and auth is held together with duct tape.

Supabase's skill fixes this by front-loading good decisions. It handles:

Row-level security policies that don't lock you out
Migration patterns that won't corrupt your data
Auth setup with proper token handling
Query optimization hints

Install with one command:

npx ai-agent-skills install supabase-postgres-best-practices

Resend's Email Agent Skills

Email is another area where AI-generated code tends to be fragile. Deliverability issues, HTML rendering problems, template management. Resend released three skills to handle this:

email-best-practices: Deliverability rules, spam filter avoidance
react-email: Component-based email templates
resend-skills: API integration patterns

The real value here is avoiding the debugging rabbit hole. Email failures are notoriously hard to diagnose. With the skill loaded, Claude generates code that handles edge cases you wouldn't think to test.

Remotion for Video Creation

This one caught me off guard. Remotion released agent skills for programmatic video creation. The demos circulating on X show people generating Instagram Reels in under 10 prompts.

Claude Code's New Parallel System Is a Game Changer

The workflow looks like:

Describe what you want in the video
Claude generates Remotion components
Preview renders in your browser
Export to MP4

People are using this for product demos, social content, and even automated video pipelines. One person mentioned spinning up 100 instances to bulk-create sample videos for cold outreach. Whether that's genius or spam depends on your perspective.

Why This Matters for Making Money

The old bottleneck was knowing how to code. The new bottleneck is knowing which tools to use and how to use them well. Skills compress months of learning into an instant.

Consider what's now possible for a solo builder:

Spin up a production database with proper security in minutes
Build a native-feeling mobile app without learning Swift
Create video content programmatically at scale
Set up transactional email that actually reaches inboxes

Each of these used to require hiring a specialist or spending weeks learning. Now you install a skill and tell Claude what you want.

The a16z charts show it: vibe coding has unleashed a torrent of new iOS apps. The App Store had basically flat growth for years, and now submissions are spiking.

The Ecosystem Is Consolidating

Watch what's happening. Anthropic released the skills spec. Major companies immediately adopted it. Now there's a race to have the best skill for each category.

This creates network effects. The tools with good skills get more usage through AI assistants. More usage means more feedback. Better feedback improves the skills. Cycle repeats.

If you're building a developer tool and don't have an agent skill yet, you're falling behind. If you're a developer not using skills, you're leaving productivity on the table.

Getting Started Today

Here's a practical workflow:

Audit your stack: List the tools you use regularly
Check for skills: Search GitHub and the skills marketplace for each tool
Install what exists: Even basic skills save time
Fill gaps with CLAUDE.md: For tools without skills, document your own patterns

The skills marketplace is growing fast. Resources like aitmpl.com track 400+ components across agents, MCPs, and templates. Worth bookmarking.

For immediate value, start with these:

# Database
npx ai-agent-skills install supabase-postgres-best-practices

# Frontend
npx ai-agent-skills install vercel-react-best-practices

# Video (if relevant)
npx skills add remotion-dev/skills

# Email
npx ai-agent-skills install resend-email-skills

What to Watch Next

The obvious next step is skills for payment processing (Stripe), auth providers (Clerk, Auth0), and infrastructure (Cloudflare, AWS). Some community versions exist, but official releases from these companies would be significant.

Also watch for skill composition. Right now skills are standalone. The interesting future is when skills can call other skills, creating compound capabilities. Imagine telling Claude to "set up a SaaS" and it chains together auth, database, payments, and email skills automatically.

We're maybe six months away from that being routine.

The Bottom Line

Skills turn AI coding assistants from helpful-but-unreliable into genuinely productive. The companies shipping skills this week see where things are going.

If you're building products with AI, this is worth an hour of setup. Install the skills for your stack, test them on a small project, and see how much faster you move.

The gap between people using skills and people not using them is going to widen quickly. Get on the right side of it.
