r/PromptEngineering: Skills Packs Dominating GitHub Trending — Deep Read of Three Top Repos Finds Mostly Behavioral Rules, Not Novel Prompt Engineering

A r/PromptEngineering post analyzes three trending GitHub skills repos for Claude Code — including forrestchang/andrej-karpathy-skills at roughly 70k stars — and finds the repos contain mostly behavioral rules and packaging rather than novel prompt engineering techniques, with underlying content often derived from Anthropic's own documentation. The author argues the skills movement represents valuable curation and distribution work, but draws a line between that and genuine prompt-engineering innovation. The thread surfaces an active community debate about whether viral skills repos represent a new engineering discipline or sophisticated prompts-as-product packaging.
