The landscape
The day's list is heavily weighted toward the AI coding-agent ecosystem: at least eight of the 36 entries are skills, plugins, or infrastructure tools designed for platforms like Claude Code, Cursor, and Codex, making that the most visible cluster. A secondary grouping of autonomous trading and investment agents appears across four entries — Vibe-Trading, a polymarket arbitrage bot, a Chinese A-share multi-agent framework, and DojoAgents. Two independent PlayStation 5 emulator projects (sharpemu and KytyPS5) surfaced simultaneously despite no apparent connection, and a 1,324-exercise fitness dataset rounds out an unusually diverse field below the top tier.
The top pick
emilkowalski/skills, described as skills for design engineers, is the day's clear leader: +2,328 stars per day, a 13.76% daily growth rate, and 582 new stars in its measurement window against a base of 16,918 total. Its absolute daily rate is more than twice that of the second-ranked project, making it the fastest-moving entry on the list by a substantial margin. That combination of a high percentage rate and the largest raw delta on the board signals concentrated, rapid new interest rather than momentum carried by an already-massive star count.
Runner-up & trends
Nutlope/hallmark — an anti-AI-slop design skill for Claude Code, Cursor, and Codex — ranks second at +959.6 stars per day and a 7.76% daily growth rate, with 12,369 total stars. OpenCut-app/OpenCut, the open-source CapCut alternative, adds +781.4 stars per day against a large existing base of 75,123, reflecting broad and sustained interest rather than a single spike. JustVugg/colibri, which claims to run the 744B-parameter GLM-5.2 MoE model on a 25GB-RAM consumer machine using pure C with no dependencies, ranks fourth at +480.4 stars per day — notable for addressing a technically specific niche at a 3.04% daily growth rate.
How to choose
Readers primarily interested in AI coding workflows have the deepest selection here: emilkowalski/skills and Nutlope/hallmark lead, but google-labs-code/stitch-skills, MengTo/Skills, tt-a1i/archify, cobusgreyling/loop-engineering, langchain-ai/openwiki, and internet-court/internet-court-skill all address related agent-tooling problems at varying stages of maturity. Those focused on local LLM inference should look at colibri (#4) for its stated ability to stream a 744B model from disk on consumer hardware. Readers following open-source media tools or gaming preservation will find OpenCut and the two independently developed PS5 emulators — sharpemu and KytyPS5 — worth tracking as parallel efforts in their respective domains.
