Connect your tools, build the valley, climb the board

Every place, quest and item in the game is a data record in the repository. Add yours from your editor or with your AI. When it is merged, it enters the game with your signature and earns points.

Start here

Copy the template
One folder per builder, under content/extensions/your-handle/. The template is a working extension, a fruit bush and a quest, ready to copy and rename.
The template Add a fruit in 10 minutes
Give your AI the map
Paste this into Claude, Cursor or any assistant. It reads llms.txt, then the guide.
```
You are helping me add content to Openfold. Read llms.txt at https://theopenfold.vercel.app/llms.txt, then the guide it links to. Content lives in content/extensions/<my-handle>/. Run pnpm check before you tell me it is done.
```
Add the MCP server read-only
9 tools that answer from your checkout: schema, check, slots, requests, template, value, preview, guide, rules. They write nothing and need no token. Claude Code and Cursor find it in a clone through .mcp.json; for any other tool, run this once in the checkout:
```
claude mcp add openfold -- pnpm -s mcp
```
What the tools answer
Read the data
The API is plain files: the hub-data document (the requests, the boards, this week) and one JSON schema per record type.
/api/Schemas
Check, then open a pull request
The same check runs in CI on every pull request. Points land when it is merged.
```
$ pnpm check
Everything passes.
```
