When you’re ready — agent builders

Compose skills into
a whole agent

When a single skill isn’t enough, bundle several into an agent — give it a soul, knowledge and memory files, tools, and guardrails. Design it in plain language, test it, and export it to run anywhere.

  • ✓ A visual composer for every part of the bundle
  • ✓ Describe it in plain language, or import a CLAUDE.md
  • ✓ Simulate, eval & export to Claude Code, Cursor & more

What are skills,
and how do they work?

AI just got a third layer. After raw model power and tool-using agents, there's a new piece: a context filesystem — a small library of instruction files your AI reads on demand. It's the part that's yours, and it's why "skills" suddenly matters.

  • 1What a skill actually is (spoiler: a Markdown file)
  • 2Why context filesystems are the next layer of AI
  • 3Skills vs. prompts vs. RAG — what's actually different
  • 4How skills bundle up into full agents you can run anywhere

The three eras of working with AI
2020 – 2022
Just the model
You typed a prompt; you got an answer. Quality lived and died on phrasing.
Model power
2023 – 2024
Models + tools
Models learned to use tools. The agent harness became as important as the model.
Tool use
2025 – now
Models + tools + a context filesystem
A library of instruction files the AI loads on demand — bundled into agents. The part that's yours.

Want to try it yourself?

From prompt to asset

Grow a rough idea into a working agent

Deposit ideas. Shape them into skills. Prove they work with evals. Compose them into agents you can reuse and remix.

1

Deposit a rough idea

Paste a prompt, a note, or describe what you want. No formatting required.

2

Shape it into a skill

The builder turns the idea into a structured, reusable skill with variables and outputs.

3

Test it with evals

Run behaviour evals to prove the skill does what it claims — before you wire it into anything.

4

Convert it into an agent

Bundle skills with a soul, knowledge files, tools, and guardrails — a full teammate, not just a prompt.

5

Publish to your portfolio

Pin your best work to a public portfolio so others can browse, fork, and learn from it.

6

Reuse, remix, compound

Clone someone else’s agent, swap a skill, run the evals again — build on the network’s work, not just yours.

Ready for more?

When one skill isn’t enough,
compose a whole agent

An agent bundles your skills with a soul, knowledge, memory, tools and guardrails — a complete, runnable teammate. You answer the six parts in plain language; the visual composer turns them into the files your AI tool actually reads.

◆
Soul
Who the agent is — its identity, principles, and operating style. The instructions it reads every time it starts.
⚖
Skills
The reusable skills you already build, attached to the agent. Improve a skill and every agent that uses it improves too.
📄
Knowledge
Documents, policies, and reference material the agent reads. FAQs, product specs, process guides — what it knows.
💾
Memory
Notes the agent keeps and updates as it works. Context that persists across sessions so it remembers what matters.
🚫
Guardrails
What it must never do, always do, how to communicate, and what’s out of bounds. Hard rules, not soft suggestions.
🔧
Tools
Capabilities it can reach: web search, code runner, APIs. Declared in the bundle so the harness knows what to enable.

Build every part in the visual composer — then simulate it, save evals so it can’t quietly regress, and export a clean package for Claude Code, Cursor, ChatGPT, MCP, or plain Markdown.

Show off your
AI craft

A public agent portfolio is different from saying “I use AI.” It shows the agents you designed, tested, and made exportable by others — here are the workflows I built, and here’s the proof they work.
