The 15-Skill Video Pipeline: How One Engineer Built an End-to-End Editor in a Night
Wang Jianshuo shipped a Chinese-podcast-to-YouTube-Shorts pipeline as 15 single-purpose Claude Code skills. The interesting part isn't the result — it's the design.
Skills As Functions: The Naming Discipline Behind a 15-Skill Video Pipeline
Wang Jianshuo spent five years trying to build AI video editing. Claude Code reproduced his progress in a night. Then he tore the codebase down and rebuilt it as 15 verbs. Here's why.
ML's Reproducibility Problem Is a Workflow Problem, Not Just a Culture Problem
Most ML papers can't be reproduced by the labs that published them. This skill turns paper reproduction into a structured 4-step workflow — and surfaces exactly where the gap is.
271K Installs Tells You Where Enterprise AI Is Actually Happening
Microsoft's Azure AI Foundry skill is the 3rd most-installed on skills.sh. That number is a dispatch from the real world of enterprise AI adoption.
Auth Has Been 'Solved' Five Times. It Keeps Getting Solved Again.
Better Auth's 43K installs in a short window suggest the current constraints — framework-agnostic, TypeScript-first, self-hostable — weren't covered by existing solutions.
Your CLAUDE.md Is 46% Filler. Caveman Proves It.
The caveman skill compresses prompts into minimal, primitive English — and when the agent performs identically on 46% fewer tokens, you learn what information wasn't actually there.
React Props Proliferate. This Is the Skill That Stops It.
Every new requirement adds a prop to the parent, which propagates to the children, which needs null checks. Vercel's Composition Patterns encodes the specific patterns that stop it — not as a blog post, but as running instructions.
Convex's Mental Model Is Different Enough That a Generic Backend Agent Gets It Wrong
Convex's pitch: write server functions, subscribe from the client, get real-time updates automatically. The agent skill is how the Convex team corrects for generic backend assumptions.
The Copywriting Skill Isn't Replacing the Writer. It's Encoding What Good Writers Do.
The coreyhaines31/marketingskills copywriting skill is a structured framework — Hormozi-style, benefit-led, metric-heavy. 82.5K installs on a skill that treats writing as a repeatable system.
Emil Kowalski Thinks Taste Is Teachable. His Skill Is the Argument.
The Emil Kowalski Design Engineering skill packages his micro-interaction sensibility as agent instructions. The claim it makes — that taste is encodable in repeatable patterns — is a bold one worth examining.
Your Design System Already Exists. You Just Can't See It.
Every codebase has an implicit design system locked in component files. Extract Design System reads them all at once and makes the invisible explicit.
The Most-Installed Skill Isn't a Coding Skill. That's the Whole Story.
find-skills from vercel-labs has 1.3M installs — more than any coding or workflow skill. What it says about where AI agent tooling actually is right now.
