AI Chat Flow

A flow pack: one collection of linked screens, each with its branches, made in one ask. Build every screen from the app screen patterns' shell and rules (below), one artifact per screen.

Screens

Screen id	Title	What it holds
`chat-empty`	Ask anything	what the assistant can do here in one line; three or four suggested prompts from the brief's domain; the composer
`chat-streaming`	Answering	the user message, the reply arriving with a visible "Stop" control and the composer locked
`chat-error`	Something failed	the failed reply with a plain cause and "Try again"; the user's message kept
`chat-result`	Result	the reply as a structured card the user can act on (save, share, edit); feedback controls; ends the flow

Main path: chat-empty → chat-streaming → chat-error → chat-result. Add the branches each screen lists as its own data-od-state frames or, when a branch is a whole screen, as a screen.

Workflow

Ask once, at most three questions, together: which branches to include, which platform (web app, iPhone, Android), and the product name if the brief doesn't give it. Accept "you pick". Never more than eight screens.
Plan the flow before the first screen. Pass flow to prepare_open_design_brief on every screen: the screens above (trimmed to the user's choice), the links between them (from, trigger label, to) and the shared navigation if the flow has one. Use the same collectionId and the screen id as screenRole.
Build each screen with its own prepare_open_design_brief call, then register it with the same collectionId, screenRole and flow.
Check the collection with check_open_design_artifact and collectionId, fix flow findings (broken links, dead ends, unfilled screens, navigation drift, store rules), then show the flow map.

Rules for this flow

Say what the assistant can't do and where its information comes from; show sources when it cites any.
Long replies keep the composer reachable; the newest message stays in view.
Mark the result screen with data-od-end.

Markup contract (shared by every app screen)

States. Each state of the screen is a sibling <section data-od-state="…">: default (populated), and the ones this pattern lists below from empty, loading, error, success, no-access, long-content. Only default is visible; the others carry hidden. The kit's check renders every state, and the preview shows them side by side.
Slots. Keep the seed's data-od-slot names (nav, toolbar, content, empty, loading) so states, links and comments line up.
Links between screens. When this screen is part of a planned flow, link to another screen with its entry path in href and its screen id in data-od-goto, and use the shared navigation the brief gives instead of drawing your own.
The app's own components. When the brief lists the app's components, build each part from one of them and mark it data-od-component="<Name>"; mark a part with no match data-od-component="new:<Name>".
Sample data. Records come from the data file the brief describes, never typed into the markup row by row: one template row or card with data-od-repeat="<list>" and data-od-bind=".<field>" inside it, single values with data-od-bind="<list>[n].<field>", and data-od-format for money, dates and numbers. Every screen that shows the same record binds to the same one.
Tokens only. Every colour, size, radius and shadow comes from the design system's :root variables. No raw hex outside :root.
Platform. Web app: the shell as given. iPhone, Android, tablet or desktop app: put data-od-device on <body> (iphone, android, tablet with data-od-orientation, or desktop-app with data-od-window="mac" or "windows"); the kit draws the device frame, status bar and home indicator around the screen, so never draw them yourself. iPhone or Android: a single column 390 px (iPhone) or 412 px (Android) wide, with a bottom tab bar instead of the side nav, a top bar with the title and a back button on inner screens, and 44 px (iPhone) or 48 px (Android) touch targets. Android screens use Material patterns (top app bar, floating action button where there is one main create action). Tablet: the sidebar collapses to an icon rail with labels in a tooltip, content in two columns where the pattern has a detail pane.
Density. Use the density the brief gives (compact, medium or airy) with the numbers from the product UI craft rules.

Seed

Start from this shell (one HTML file, inline CSS). Replace the comments; keep the structure.
