This is the Beijing-morning snapshot of the UTC day that just closed, and the volume is light: headroom leads with around 59 stars and the rest of the board sits in the teens and twenties. What ties the top together is that almost every entry exists to make a coding agent work better. Headroom compresses tool outputs, logs, and RAG chunks before they reach the context window, which is the most 2026 problem imaginable. Behind it, ponytail is an agent persona, codebase-memory-mcp feeds the agent a code graph, mattpocock/skills and superpowers ship skill libraries, and kilocode is the agent platform itself. The board is less a snapshot of what developers are building and more a snapshot of what they are building with.

The outsider worth a look is EpicGames/lore at number seven. Epic, the company behind Unreal Engine and Fortnite, open-sourced a centralized, content-addressed version control system aimed at projects where terabytes of binary assets dwarf the code, a quiet shot at Perforce that has nothing to do with the agent wave around it. Two other non-agent entries round things out: tw93/Pake at five is the evergreen Rust tool for wrapping a website into a tiny desktop app, climbing on its usual rhythm, and google-research/timesfm at ten is the lone big-lab entry, a pretrained time-series forecaster still ticking upward.
