fmtlib/fmt opens GitHub trending on September 3, 2026, at 24,556 stars. The C++ formatting library last shipped 12.2.0 on June 16, 2026, adding a C API in fmt-c.h; no same-day release note explains the rank-1 spike beyond the daily GitHub trending window. The board is a clean break from the September 2 GitHub list, where Gitlawb/openclaude sat at 1. google-research/timesfm is new at 2 with 30,313 stars. A GitHub Trending Repos API pull at 06:01 UTC returned 10 rows and 0 overlap with September 2.

What today's GitHub repos reveal
Agent tooling still dominates, but yesterday's research-skill cluster is gone. Five of ten READMEs mention agents or local inference (ponytail, chrome-devtools-mcp, hermes-agent, sie, atlas). VoiceStudio and TypeWords are local apps; Sequoia-X is a China equity bot; fmt and timesfm are libraries with 12-plus-year and Google Research pedigrees.
Star count does not equal rank. hermes-agent's 240,366 stars sit at 7 while fmt's 24,556 sits at 1, which is how GitHub's trending window scores recent velocity over lifetime stars. The 0-for-10 overlap with September 2 is the day's fact: this feed turns over even when the theme (agents) does not.
