GitHub trending August 10 2026: the top 5 compared

Star gains cover Aug 10 to 16, 2026. Totals were checked on GitHub on October 16, 2026.

1. Diagram Design: diagrams that look like a magazine made them

Stars: +14.7K this week · about 55.8K total

What it is: A "skill," which is a set of instructions you add to an AI helper. This one teaches Claude Code, Codex, Copilot, Cursor and others to draw editorial-style diagrams. The README lists 44 diagram types. Each one comes out as a single web file you can open anywhere.

Who it's for: Teachers, founders, managers and anyone who explains how things work.

Everyday use: "Draw how a customer order moves from our website to the warehouse." You get a clean chart for your slides.

Install it: You need Node.js, a free program many tools run on. Copy and paste this:

npx skills add cathrynlavery/diagram-design

Let Claude or Codex do it:

Install Diagram Design from github.com/cathrynlavery/diagram-design, then draw a simple 3-step diagram of how I make my morning coffee.

2. Prime Agent: a coding agent that learns how to work better

Stars: +8.5K this week · about 22.0K total

What it is: An open-source agent from Prime Intellect for coding and research tasks that run for a long time. It can split work across helper agents. It keeps running if you close the terminal. A /refine command reviews what it just did and makes small, evidence-backed updates to its own notes and skills.

Who it's for: Developers who hand AI big jobs, like "refactor this whole app."

Everyday use: Start a long cleanup job, close the terminal window, and reconnect later to see the results.

Install it: On Mac or Linux, copy and paste this:

curl -fsSL https://app.primeintellect.ai/prime-agent/install.sh | sh

On Windows, the README gives a PowerShell line instead.

Let Claude or Codex do it:

Install Prime Agent from github.com/PrimeIntellect-ai/prime-agent and explain how to start my first task with it.

3. Semantica: AI answers you can trace back

Stars: +5.3K this week · about 14.1K total

What it is: A Python toolkit that turns messy company data into a knowledge graph. That's a map of facts and how they connect. Your AI then works from that map, and you can see why it gave each answer.

Who it's for: Data teams in banks, hospitals, law firms and other places where someone may ask, "Why did the AI do that?"

Everyday use: Load a folder of contracts and find which clauses connect to which suppliers.

Install it: Copy and paste this:

pip install semantica

Let Claude or Codex do it:

Install Semantica from github.com/semantica-agi/semantica and build a small knowledge graph from the PDFs in my contracts folder.

4. TencentDB Agent Memory: still climbing

Stars: +4.0K this week · about 29.2K total

What it is: Tencent Cloud's shared memory hub for AI agents. It saves chats, docs and code so every helper on a team can reuse them. It was number two the week before.

Who it's for: Teams with several people coding with AI on one project.

Everyday use: A new teammate's AI already knows your project's rules on day one.

Install it: You need Docker. After you fill in the .env settings file, the README's last step is:

./start-all.sh

Let Claude or Codex do it:

Set up TencentDB Agent Memory from github.com/TencentCloud/TencentDB-Agent-Memory following its README, and ask me for each setting.

See TencentDB Agent Memory on GitHub

5. Agent Skills: senior-engineer habits for your AI

Stars: +3.3K this week · about 107K total

What it is: Addy Osmani's pack of 25 skills and 9 slash commands. They walk your AI through the steps good engineers follow: write a spec, plan, build, test, review, ship.

Who it's for: Anyone whose AI helper writes code fast but skips the boring checks.

Everyday use: Type /spec before a new feature, so your AI asks the right questions before it writes a single line.

Install it: Copy and paste this:

npx skills add addyosmani/agent-skills

Let Claude or Codex do it:

Install Agent Skills from github.com/addyosmani/agent-skills and show me how to use /spec and /plan on my next feature.

💡 Tip: Skills don't change your AI's brain. They're instruction files it reads when the task fits. You can remove them any time.

See Agent Skills on GitHub

Which one should you try first?

• You explain things to people: start with Diagram Design. It's the most fun here.
• You code with AI and want fewer mistakes: add Agent Skills.
• You give AI long, big jobs: try Prime Agent.
• You work with sensitive business data: look at Semantica.

⚠️ Heads up: Skills and agents use your AI plan when they run. Long jobs can burn through credits, so start small.
