Lorebarn: a team wiki for specs, runbooks and the company handbook
Nested pages in markdown with live preview, version diffs and restore, presence on every page, and full-text search.
How it's built
Lorebarn needed a page tree that updates for everyone, a version kept on every save, presence on each page, full text search and email invites. Each of those is a part of Elements, so the agent spent its 17 minutes on the wiki itself.
What Elements gave the app
- Live pages and tree. Pages are a LiveTable split by space, so a save, a new page or a move in the tree shows up in every open tree, page and home screen at once.
- A version on every save. Each edit is checked against the latest version, keeps a snapshot in the same transaction, and tells a late editor who saved first. History restores a version through the same live table, so every open copy updates.
- Presence. A channel tracks who is on each page and who is editing, and every open copy of the page shows the same people as they arrive, start typing and leave.
- Full text search. Search ranks matches across every page and highlights them, from a weighted search column the migration defines.
- Invites and roles. Admins invite members by email and change roles with
@rpccalls that check for an admin first. - Data from SQL files. Migrations define the wiki and seed one admin, three members, three spaces with 23 nested pages, 64 saved versions and a pending invite.
What the project server gave the agent
The project server runs alongside the agent and answers as soon as a file is saved: it type-checks the templates, TypeScript and SQL, applies migrations and reruns the tests, so every question came back right away and the agent kept building.
What shipped
The app type-checks with zero errors and all 28 tests pass. Every page works on desktop and phone.

The prompt
What Claude was given to build this app.
Build a team wiki named lorebarn. Accounts: admin and member. Admins invite members by email. - Spaces (Engineering, Product, Handbook), each with a tree of pages that can nest. - Pages are markdown with a live preview while editing. - Every save keeps a version; see a page's history and the diff between two versions, and restore one. - See who else is viewing or editing a page right now. - Full text search across all pages. - Recently edited pages on the home screen. Seed one admin, three members, three spaces and about twenty pages of realistic content with history. Show the seeded logins on the sign-in page. Edits, the page tree and presence update in real time.
