Skills,connected.
A skill teaches your AI one thing well. Connect enough of them and you get something that works like a whole — yours, shaped by what you do.
Drag to turn. Each point is a real skill.
Find it. Read it.Install it.
The Windows app writes each skill into the right folder, in the right format for your agent — and shows you exactly what it wrote.

01
One skill.
Not a plugin, not an app. A short document your AI reads before it starts — how to keep a tone, how to read a spreadsheet, how to review a diff.
Written in plain Markdown. You can read every one before you install it.

# How we write
- Short sentences. One idea each.
- No superlatives. Never "revolutionary".
- Say plainly what does not work yet.
## Words we avoid
seamless · effortless · powerful · cutting-edge02
Then they connect.
One skill calls the next. Read the document, pull the numbers, keep the voice. The order you put them in is the thing you actually built.
Share the whole arrangement with a link. The other person gets the same setup.

Found 14 pages, 3 tables, a revision history.
Q3 down 8% — the drop is in one region, not all four.
One region slipped 8% last quarter. The other three held.

And they land somewhere real.
The desktop app writes them into your project — the right folder, the right format for each agent. It shows you what it wrote and it can take it back out.
Nothing is written outside the folders you register.

The website shows you what a skill becomes. Installing happens in the desktop app — a browser cannot write to your folders.
One shape
Everything you install becomes one thing
Skills do not sit in a folder side by side. They reach each other — what one knows, the next one can use.
Highlights.
Get the app ›Build
Put skills in order.
Arrange skills into a tree, see where two of them contradict each other, hand the whole thing over as one link.
Install
Five agents, one click.
Claude Code, Claude, Codex, Cursor, ChatGPT — each gets the right file in the right place.
MCP
Servers, wired for you.
Pick an MCP server, say where it goes, and the app checks that it actually starts.
Plugins
Bundles, opened up.
Sixteen thousand skills that were hiding inside plugin bundles, listed one by one.
Trees
Sets, ready to go.
Skills already arranged for a job — a documents set, a design set, a coding-discipline set. Open one, see the tree, install it whole.
World tree
What others connected.
A board for the trees people built and the questions they asked along the way.
