Ten picks from the GitHub trending board for the week of August 30, 2026. The week skews agent skills and plugin ecosystems — diagram skills, a science-skills library, the official Claude plugin directory, Cursor’s plugin spec — with a few solo-builder gems mixed in (an AI job-search framework, a screenshot-to-code classic). Grouped by theme:

Agent tooling & skills

  • archify (tt-a1i) — an agent skill for architecture, workflow, sequence, data-flow, and lifecycle diagrams: self-contained HTML with motion, crisp export, and verifiable structure. The week’s biggest mover at ~14.9k stars.
  • scientific-agent-skills (K-Dense-AI) — “turn any AI agent into an AI Scientist”: 165 validated agent skills plus 100+ scientific databases covering biology and beyond; claims 190k+ scientist users.
  • garden-skills (ConardLi) — an open-source collection of reusable agent skills covering web design, knowledge retrieval, and image generation.
  • claude-plugins-official (anthropics) — Anthropic’s own managed directory of high-quality Claude Code plugins — the official counterpart to the community marketplace that topped last week’s roundup.
  • cursor/plugins — Cursor’s plugin specification and official plugins; more evidence that plugin ecosystems are becoming the organizing unit of agent tooling.

Local-first AI & learning

  • openhuman (tinyhumansai) — a Rust “personal AI superintelligence”: a brain that builds a local-first memory of your life, orchestrates agent fleets and workflows, and does deep research.
  • ai-engineering-from-scratch (rohitg00) — “Learn it. Build it. Ship it.” — a from-scratch path into AI engineering, trending at ~3.5k stars.
  • OpenMAIC (THU-MAIC) — open multi-agent interactive classroom: an immersive multi-agent learning experience in one click.

Solo-builder utilities

  • ai-job-search (MadsLorentzen) — an AI job application framework that runs on your machine via Claude Code: evaluate postings, tailor CVs, write cover letters, prep interviews. Fork it and own it — no SaaS.
  • screenshot-to-code (abi) — the classic that keeps trending: drop in a screenshot, get clean HTML/Tailwind/React/Vue code.
