Claude Code Skills Setup: 1 Person Doing the Work of 30

“Can one person run an entire startup?”

Six months ago, I would have said no. But after seeing what this combination of Claude Code skills can do, I believe we’ve entered an era where a skeleton crew can genuinely operate a full-stack business.

Marketing: One Collection Covers Everything

Corey Haines released a free marketing skills collection that packs 23 skills covering nearly every area a marketer needs.

• CRO: Landing pages, signup flows, onboarding, forms, popups, paywall optimization
• Copy and content: Copywriting, copy editing, email sequences, social content
• SEO: SEO audits, programmatic SEO, competitor comparison pages, schema markup
• Ads and analytics: Paid ads, GA4/GTM tracking, A/B test design
• Strategy: 140 SaaS marketing ideas, 70+ marketing psychology models, launch strategy, pricing strategy

After installation, say “improve my landing page conversion rate” and the page-cro skill kicks in. Say “write a 5-part welcome email sequence” and the email-sequence skill takes over automatically.

A single prompt can produce a complete video. CapCut-style effects are also straightforward to implement with Remotion.

Slides: Build Custom Presentation Skills with Skill-Creator

The built-in Skill-creator lets you build your own PPT generation skills. There are people using it to create Steve Jobs-style presentation skills.

• Text input alone produces professional-grade slides
• Saves significant time for PMs and marketers building decks

Image Generation: Solved with API Connections

Claude cannot generate images natively, but adding an API-connected skill like Gemini lets you produce high-quality images from prompts. Our team already has image and video generation bots embedded in Slack.

UI: Pro-Level Upgrade with Frontend-Design Skill

A single 42-line markdown directive completely transforms the UI that Claude produces. This is essential for solo developers and teams without a dedicated designer.

• Reach production quality without a separate design tool

Code Quality: Code Simplifier Has You Covered

The Claude Code team open-sourced a tool they were using internally.

• Automatic cleanup and refactoring of complex codebases
• Ideal for post-session code cleanup and PR reviews
• Install with claude plugin install code-simplifier

After using it myself, code review time dropped noticeably. It feels like having an extra senior developer on the team.

The Real Takeaway

The point of this combination is not “each skill replaces one specialist.” It is that a single person can fluidly move between multiple roles.

We have shifted from an era of accumulating skills to an era of composing them. The depth of your skill stack - not the size of your team - is what determines competitive advantage now.
