cathrynlavery/diagram-design debuts at rank 1 on GitHub Trending Repos August 13, 2026, after Top AI Product logged about 2,951 stars in a single day on August 12 as the Claude Code skill pack for editorial HTML/SVG diagrams went viral. Yesterday's #1, msitarzewski/agency-agents, falls to rank 5. macro-inc/macro opens at rank 2 as a new AGPLv3 team workspace. semantica-agi/semantica holds the podium at rank 3 after sitting at #2 on August 12.

What changed on GitHub since August 12

Compared with the August 12, 2026 GitHub daily post, diagram-design and macro enter at ranks 1 and 2 while agency-agents drops from #1 to #5. The board stays at 17 repositories.

  • Big movers: msitarzewski/agency-agents (#1 to #5); stablyai/orca (#10 to #4); semantica-agi/semantica (#2 to #3); paperclipai/paperclip (#11 to #10)
  • New entrants: cathrynlavery/diagram-design (#1); macro-inc/macro (#2); shiyu-coder/Kronos (#6); hugohe3/ppt-master (#8); infiniflow/ragflow (#9); NVIDIA-NeMo/Switchyard (#11); ZuodaoTech/everyone-can-use-english (#12); smicallef/spiderfoot (#13); localsend/localsend (#14); Lightricks/LTX-2 (#15); embabel/embabel-agent (#16); cactus-compute/needle (#17)
  • Re-entry: NanmiCoder/MediaCrawler (#7)
  • Drop-offs from August 12 board: nvm-sh/nvm; addyosmani/agent-skills; ZhuLinsen/daily_stock_analysis; vitali87/code-graph-rag; anthropics/skills; 3b1b/manim; HKUDS/DeepTutor; huggingface/transformers; harveyai/harvey-labs; jaywcjlove/awesome-mac; calesthio/OpenMontage; practical-tutorials/project-based-learning; PrimeIntellect-ai/prime-agent
  • Holds near top: semantica-agi/semantica (still top 3); paperclipai/paperclip (still top 10)

August 13 is a diagram-and-workspace reset day. diagram-design's August 12 star surge (about 2,951 stars in one day per Top AI Product) knocks agency-agents off #1 after a single day on top, while macro's AGPLv3 workspace debut at #2 widens the board beyond agent-skills packs. Only four August 12 names remain: semantica at #3, orca at #4, agency-agents at #5, and paperclip at #10.

The skills-cluster concentration that defined August 12 (five agent-skills repos) collapses. In its place, NVIDIA-NeMo/Switchyard at #11 and embabel-agent at #16 keep agent infrastructure on the board through routing and JVM frameworks rather than persona packs. MediaCrawler's return at #7 and Kronos at #6 pull social scrapers and finance models back into the mix. The August 13 signal is a near-full board refresh led by an editorial diagram skill, not another agency-agents flip.
