🔥 Hot Repo: 21K Stars for Matt Pocock's Claude Code Skills

The Claude Code Skill Pack That Won't Stop Growing mattpocock/skills is a public collection of Claude Code slash commands built and open-sourced by Matt Pocock, creator of Total TypeScript and a well-known TypeScript educator. The repo crossed 21,507 stars on April 26, 2026 — gaining 2,507 stars in a single day — roughly 80 days after it was created on February 3, 2026. It has 1,775 forks. What a Skill Actually Is Claude Code supports a skills system: Markdown files SKILL.md placed in your .claude/ directory that register as slash commands. When invoked, a skill injects structured instructions into Claude's context for the session — effectively scripting how Claude behaves for a specific workflow. Pocock's repo is a public registry of reusable skills, installable in a single command: bash npx skills@latest add mattpocock/skills/grill-me The Grill-Me Skill That Started It All The repo's breakout moment came in March 2026 when grill-me went viral on Twitter and landed on Hacker Newshttps://news.ycombinator.com/item?id=47550391.

The skill itself is three lines of content: "Interview me relentlessly about every aspect of this plan until we reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one-by-one. For each question, provide your recommended answer." Pocock's thesis: most AI-assisted coding failures happen not because the model can't write code, but because requirements were never fully specified. grill-me inverts the usual dynamic — instead of the developer asking Claude questions, Claude interrogates the developer until every decision branch is resolved before a single line of code is written. 20+ Skills Across Four Categories The repo has grown well beyond grill-me: Planning & Design - to-prd — synthesizes the curr
