@ouispec/cli

The assistant's surfaces and knowledge, generated from a React app's own code (ADR-0220, ADR-0226). A deterministic TypeScript pass (no LLM, no network, no clock) over the app's routes, its page component trees, its design system's bound controls, its room catalogs and its API's OpenAPI document.

oui generate            # writes <out>/oui-manifest.json and <out>/oui-knowledge.json
oui generate --check    # CI: fails if either is stale, or any declaration is invalid

--config <path> names the settings file (default ./oui.config.json). The same command is installed as closure-oui.

oui.config.json

Required, and explicit: nothing an app depends on has a default, so a misconfigured app fails naming the setting instead of generating an assistant that can do nothing.

apiClient was replaced by apiSpec.

Design systems

Each package in designSystem must resolve from the app and name its control table in its package.json:

{ "oui": { "agentControls": "./dist/agent-controls.json" } }

closure.agentControls is also read during the transition. A package declaring both is an error. A room package names its catalog the same way, under oui.agentCatalog (or closure.agentCatalog).

A package's subpath exports are the package's: a control imported from @acme/ui/react is read against @acme/ui's control table, and the same holds for a room package's hosts, a person-only component and a mapped package. When designSystem lists a package and a subpath of it, an import takes the longest name it is under. A package whose name only starts the same (@acme/ui-extras) is a different package.

Third-party design systems (tier 2, ADR-0226 §2.3)

An app on MUI, Mantine or shadcn/Radix maps that design system's controls in a JSON file per package (tier2-mapping.json in @ouispec/contract: kind, callbacks, valueFrom, controlled, options, titleProps, and parts for a control under a namespace or made of parts). For each mapping oui generate writes <out>/bound/<package>.ts (@mantine/core → mantine-core.ts) and its control table beside it:

• one wrapper per mapped control, under the package's own export names, built from @ouispec/bindings/react: it accepts agent, registers the mapped kind with the app's own callback, returns that callback's result, reports disabled, and renders the component unchanged (props, ref, static members);
• a namespace (Select, Tabs) keeps every other member (Select.Trigger, Tabs.List);
• each export keeps the component's own type, and the module imports @ouispec/bindings/jsx, which adds agent to JSX.

The app imports mapped controls from the bound module. Each use is read as a tier 1 control's: its binding, title, options (from the prop the mapping names, or from the items a compound control renders) and schema. The program reads the module as this run emits it, so a page resolves it in --check and on the first run. A use that does not pass the prop that shows its value (controlled) is printed as a warning and returned in result.tier2.uncontrolled, beside every use in result.tier2.uses, for the conformance kit's checkTier2.

Routes

• JSX: <Route path element>, nested routes joined to their parent's path, index routes at their parent's path, pathless routes that group their children, Component and lazy props.
• Data routers: createBrowserRouter([...]), createHashRouter, createMemoryRouter, createStaticRouter and useRoutes, with children (literal or constant arrays), index, element, Component and lazy: () => import('./route') route modules (their Component export, else their default).
• lazy(() => import(...)) and React.lazy(...), a default export or .then(m => ({ default: m.X })).
• A route whose element has child routes is a layout: it becomes the shell: frame of the pages under it, when it holds anything someone can use.
• Splats (*) and redirects (a <Navigate>, or a component that only renders one) are not pages.

What fails the build

• A missing or unknown setting in oui.config.json.
• A designSystem package that cannot be resolved, declares no control table, or declares both keys.
• On an enforced page: a control with no binding, a raw element someone can use (a button, an input, or anything with onClick, onChange, onInput, onSubmit, onDoubleClick, onPointerDown, onMouseDown or onKeyDown), and a component with no control table entry that takes a callback prop, whether from a third-party library or a design-system export the table leaves out. Each is fixed by a bound control, or by data-non-agent="<reason>" saying why the assistant never needs it.
• A route the generator cannot read (a path, children or lazy that is not known at build time).
• An apiSpec that cannot be read or is not OpenAPI 3; a mutate or transaction naming an operationId the document does not have; either in an app with apiSpec: null.
• An effect that is not one of the vocabulary's, or a transaction whose approvalMinutes is not 1–30.
• A control table entry of a kind the table does not register, or a registration that is not valid.
• A room recipe naming an entry the room does not have.
• On an enforced page, a mapped control imported straight from its package (§2.5 row 6): the error names the bound import.
• A mapping that does not match its schema, names a package the app cannot resolve, maps a package also in designSystem (or one of its subpaths, or a package one of whose subpaths designSystem lists), maps a package another mapping maps, uses a kind no design system registers, or does not fit the package's types (an export it does not have, a prop its component does not take).
• A stale bound module or control table, or a file in <out>/bound/ no mapping emits (--check; writing removes it).

Person-only components (ADR-0228)

Some components exist so that the person, and only the person, can do something. The approval card where someone approves an irreversible action is one. A package lists them in its package.json, each with the reason:

{ "oui": { "personOnly": { "ApprovalCard": "Only the person approves an irreversible action" } } }

On one of these components, the generator fails the build for:

• an agent prop, even { nonAgent };
• a spread of props, which could carry a binding the build cannot see.

What such a component renders is never bound, so its callbacks need no data-non-agent. @ouispec/agent-react declares ApprovalCard this way.

The contract's vocabulary (ADR-0226 §2.6)

• Effects. A binding, a room action and an API tool declare one ActionEffect: view, selection, navigate, open, edit, file, mutate (an API operationId), job (settles on its outcome) or transaction (irreversible: runs only on the person's approval of the exact call, ADR-0228). destructive: true marks a write that removes what the person made.
• Control kinds. The built-in kinds are closed. A design system adds an x- kind by registering it (registerControlKind) and listing the same registration under $kinds in its control table, with its schema derivation as data.
• Rooms. A field animates only when it declares animation: { keyframeable: true }. A room may declare its own problems kinds and recipes; recipes name the room's entries with {action:<id>}, {command:<id>}, {field:<id>}, {keyframeable} and {room}. The generator infers no recipe.

App room catalogs need Vite

A catalog in appCatalogs is code: its entries may be built by functions, and its imports resolve only as the app's build resolves them. The generator loads each one through the app's own Vite config (vite must be in the app's own node_modules) and keeps only its declarations. An app without Vite ships its catalog in a package under oui.agentCatalog instead, as plain data.
