affaan-m/ECC takes rank 1 on the GitHub trending board for September 7, 2026, with 251,999 stars, moving up from rank 2 a day earlier. The swap pushes mattpocock/skills to rank 2 even though that catalog now shows 255,332 stars, up 2,110 from the 253,222 count cited on September 6. ECC is an agent performance system for Claude Code, Codex, OpenCode, and Cursor, covering skills, instincts, memory, and security for coding agents. DietrichGebert/ponytail is the session's big mover, sliding from rank 3 to rank 9. Three new repos join the top 10: openai/skills, blader/humanizer, and llvm/llvm-project. The snapshot is as_of 2026-09-07T08:01:38.626101+00:00, microseconds 626101.
Top trending repos on GitHub: September 7
affaan-m/ECC: Agent performance system for Claude Code, Codex, OpenCode, and Cursor. It climbed from rank 2 to rank 1 with 251,999 stars on the September 7 pull. The README frames the project as skills, instincts, memory, and security for coding agents, which matches the rest of a board packed with agent tooling.
mattpocock/skills: Skills for Real Engineers, now at 255,332 stars. It held rank 1 on September 6 with 253,222 stars and still gained 2,110 stars overnight, yet lost the trending slot to ECC. Total stars and trending rank are not the same signal; the catalog remains the highest-star repo on this top 10.
cathrynlavery/diagram-design: HTML and SVG kit with 38 editorial diagram types. It jumped from rank 7 to rank 3 as stars moved from 25,960 yesterday to 32,850 today. The climb is a four-rank move, short of the five-rank big-mover cutoff, and it is the only visual-docs project in the current 10.
NousResearch/hermes-agent: The agent that grows with you. It holds rank 4 with 242,742 stars, a fixture beside ECC and the skills catalogs rather than a same-day news spike.
openai/skills: Skills Catalog for Codex. New at rank 5 with 25,737 stars, it is the OpenAI-branded counterpart to mattpocock/skills and the two skills repos that left the board.
anomalyco/opencode: Open source coding agent. It climbed from rank 8 to rank 6 with 205,464 stars, up from 204,838 on September 6.
blader/humanizer: Skill that removes signs of AI-generated writing. New at rank 7 with 44,628 stars, it sits next to repos that teach agents how to write more, a split the GitHub trending repos API makes easy to watch day over day.
llvm/llvm-project: LLVM compiler toolchain. New at rank 8 with 40,279 stars. No widely reported trigger identified for September 7, 2026 beyond the project's standing as compiler infrastructure; it is the odd non-agent entry in this 10.
DietrichGebert/ponytail: Quoted as making an AI agent think like the laziest senior dev. It is the only five-rank-plus mover, falling from rank 3 to rank 9 with 130,038 stars still on the board.
ruvnet/ruflo: Multi-player swarms and autonomous workflows. It slipped from rank 9 to rank 10 with 71,129 stars, versus 70,779 yesterday.

What today's GitHub trends reveal
Coding-agent catalogs still own this board. Eight of the 10 rows are agents, skills packs, or swarm tooling: ECC, mattpocock/skills, hermes-agent, openai/skills, opencode, humanizer, ponytail, and ruflo.
The skills lane is crowded enough that two skills repos (anthropics/skills and humanlayer/skills) fell off while openai/skills entered at rank 5. mattpocock/skills kept adding stars (253,222 to 255,332) and still lost rank 1, which is a reminder that GitHub trending is a velocity board, not a lifetime star table.
diagram-design at rank 3 with 32,850 stars is the documentation exception. llvm-project at rank 8 with 40,279 stars is the compiler exception. Everything else is people installing, stripping, or routing coding agents on a U.S. holiday Monday.
