Use when working with @json-render/core, defining schemas, creating catalogs, or building JSON specs for UI/video generation.\n---\n\n# @json-render/core\n\nCore package for schema definition, catalog creation, and spec streaming.\n\n## Key Concepts\n\n- **Schema**: Defines the structure of specs and catalogs (use `defineSchema`)\n- **Catalog**: Maps component/action names to their definitions (use `defineCatalog`)\n- **Spec**: JSON output from AI that conforms to the schema\n- **SpecStream**: JSONL streaming format for progressive spec building\n\n## Experimental Decision-Model Composition\n\nFor decision-model composition, import `experimental_composeSpec` and `experimental_createEvaluator` from `@json-render/core`. These APIs are unreleased; use a source build until published, then pin exact versions. Experimental exports and `Experimental_` types can change in any release.\n\n- Run the Gateway evaluator server-side with `{ model: \"typesafe-ai/jev\", apiKey: process.env.AI_GATEWAY_API_KEY! }`. A plain model identifier is required; Jev is the current example; do not import a provider constructor.\n- Call `experimental_composeSpec({ catalog, candidates, prompt, evaluate, initialState, signal })`. It is an async generator; stream `step.spec` snapshots to your existing renderer and inspect `complete.stopReason` (`finish`, `limit`, `unavailable`). Errors and cancellation throw; retain the last snapshot as partial UI.\n- New trees default to `strategy: \"batch\"`: one evaluation selects root/membership, then a second arranges the selected elements when needed. The first snapshot contains selected content in catalog order under the root's default/first slot. Resource variants share one exclusive question; repeated counts include the root. Root selection takes precedence over conflicting speculative membership for that recipe/resource. Equal sibling positions retain catalog order. Combined layouts are validated before publication; cycles or excessive depth throw. `maxElements` caps batched creation (default 32). Limit-truncated selections or a missing required layout call return `limit`. Use `strategy: \"sequential\"` for legacy `next`/`parent` adapters or sequential creation. Edits stay sequential.\n- Batched trace steps use `choice: \"select\" | \"layout\"` and an `answers` record. Count each trace as one evaluation, including its tokens and latency once. Custom evaluators must answer every offered question; names/choices are opaque and include `root`/`select_*`, then `parent_*`/`order_*` for batches.\n- For follow-up edits, pass the selected version as `initialSpec`. It is cloned and validated; the evaluator may add, replace, remove non-root subtrees, or move/reorder them. Unchanged IDs, bindings, and state are preserved. Optional `elementDescriptions` shares identifying descriptions without exposing raw props/state. `initialState` overrides the seed state. Seeds must be valid trees within the catalog, expression subset, and depth limit. Matching recipes consume usage/resource limits; removals/replacements release them. Replacements/moves use two evaluations (select target, then recipe/destination), each counted against the budget. Treat operation and position keys as opaque.\n- Supply atomic candidates with `{ id, description, element: { type, props, on?, visible? }, root?, maxUses?, resource? }`. Catalog alone is insufficient: the app must supply values and binding recipes. Jev chooses elements and parent slots, never free-form text or code. It never executes actions.\n- Candidates are configured component instances, not page templates. Build them from current app records/operations or bind props to `initialState`; offer explicit alternatives for chart types, field configurations, and layout variants. The model chooses grouping and order within those options. Name required sections in prompts; structural validity does not imply semantic completeness.\n- V1 supports flat Spec catalogs, named slots, literals, `$state`, `$bindState`, and state visibility. No prebuilt children, repeat/watch, computed/template/conditional props, or custom directives. Success/error callbacks must reference allowed actions. Events must be declared in the component catalog.\n- Props and action params are validated against initial state without applying schema transforms/defaults. Supply valid initial values and validate/authorize action calls at runtime. Built-ins without parameter schemas get name validation only.\n- `root` defaults true, `maxUses` defaults one, shared `resource` values make alternatives mutually exclusive. Defaults: 32 evaluations (terminal calls included; no extra finish call for batches), depth eight, 10-second Gateway timeout per call. Supply an overall abort signal.\n- Candidate descriptions, prompt, instructions, topology, and explicit `context` are sent to the evaluator. Initial state and raw props/binding values are not sent automatically.\n- For custom providers implement `Experimental_CompositionEvaluator`: accept `{ state, questions, signal }`, return `{ answers: { [question]: { choice, confidence? } }, usage?: { inputTokens? } }`. Only return offered criteria keys.\n\nSee `packages/core/README.md` and `/docs/jev` for app integration and source-build instructions. The web playground is an example consumer, not a dependency of the API.\n\n## Defining a Schema\n\n```typescript\nimport { defineSchema } from \"@json-render/core\";\n\nexport const schema = defineSchema((s) => ({\n  spec: s.object({\n    // Define spec structure\n  }),\n  catalog: s.object({\n    components: s.map({\n      props: s.zod(),\n      description: s.string(),\n    }),\n  }),\n}), {\n  promptTemplate: myPromptTemplate, // Optional custom AI prompt\n});\n```\n\n## Creating a Catalog\n\n```typescript\nimport { defineCatalog } from \"@json-render/core\";\nimport { schema } from \"./schema\";\nimport { z } from \"zod\";\n\nexport const catalog = defineCatalog(schema, {\n  components: {\n    Button: {\n      props: z.object({\n        label: z.string(),\n        variant: z.enum([\"primary\", \"secondary\"]).nullable(),\n      }),\n      description: \"Clickable button component\",\n    },\n  },\n});\n```\n\n## Generating AI Prompts\n\n```typescript\nconst systemPrompt = catalog.prompt(); // Uses schema's promptTemplate\nconst systemPrompt = catalog.prompt({ customRules: [\"Rule 1\", \"Rule 2\"] });\n```\n\n## SpecStream Utilities\n\nFor streaming AI responses (JSONL patches):\n\n```typescript\nimport { createSpecStreamCompiler } from \"@json-render/core\";\n\nconst compiler = createSpecStreamCompiler<MySpec>();\n\n// Process streaming chunks\nconst { result, newPatches } = compiler.push(chunk);\n\n// Get final result\nconst finalSpec = compiler.getResult();\n```\n\n## Dynamic Prop Expressions\n\nAny prop value can be a dynamic expression resolved at render time:\n\n- **`{ \"$state\": \"/state/key\" }`** - reads a value from the state model (one-way read)\n- **`{ \"$bindState\": \"/path\" }`** - two-way binding: reads from state and enables write-back. Use on the natural value prop (value, checked, pressed, etc.) of form components.\n- **`{ \"$bindItem\": \"field\" }`** - two-way binding to a repeat item field. Use inside repeat scopes.\n- **`{ \"$cond\": <condition>, \"$then\": <value>, \"$else\": <value> }`** - evaluates a visibility condition and picks a branch\n- **`{ \"$template\": \"Hello, ${/user/name}!\" }`** - interpolates `${/path}` references with state values\n- **`{ \"$computed\": \"fnName\", \"args\": { \"key\": <expression> } }`** - calls a registered function with resolved args\n\n`$cond` uses the same syntax as visibility conditions (`$state`, `eq`, `neq`, `not`, arrays for AND). `$then` and `$else` can themselves be expressions (recursive).\n\nComponents do not use a `statePath` prop for two-way binding. Instead, use `{ \"$bindState\": \"/path\" }` on the natural value prop (e.g. `value`, `checked`, `pressed`).\n\n```json\n{\n  \"color\": {\n    \"$cond\": { \"$state\": \"/activeTab\", \"eq\": \"home\" },\n    \"$then\": \"#007AFF\",\n    \"$else\": \"#8E8E93\"\n  },\n  \"label\": { \"$template\": \"Welcome, ${/user/name}!\" },\n  \"fullName\": {\n    \"$computed\": \"fullName\",\n    \"args\": {\n      \"first\": { \"$state\": \"/form/firstName\" },\n      \"last\": { \"$state\": \"/form/lastName\" }\n    }\n  }\n}\n```\n\n```typescript\nimport { resolvePropValue, resolveElementProps } from \"@json-render/core\";\n\nconst resolved = resolveElementProps(element.props, { stateModel: myState });\n```\n\n## State Watchers\n\nElements can declare a `watch` field (top-level, sibling of type/props/children) to trigger actions when state values change:\n\n```json\n{\n  \"type\": \"Select\",\n  \"props\": { \"value\": { \"$bindState\": \"/form/country\" }, \"options\": [\"US\", \"Canada\"] },\n  \"watch\": {\n    \"/form/country\": { \"action\": \"loadCities\", \"params\": { \"country\": { \"$state\": \"/form/country\" } } }\n  },\n  \"children\": []\n}\n```\n\nWatchers only fire on value changes, not on initial render.\n\n## Validation\n\nBuilt-in validation functions: `required`, `email`, `url`, `numeric`, `minLength`, `maxLength`, `min`, `max`, `pattern`, `matches`, `equalTo`, `lessThan`, `greaterThan`, `requiredIf`.\n\nCross-field validation uses `$state` expressions in args:\n\n```typescript\nimport { check } from \"@json-render/core\";\n\ncheck.required(\"Field is required\");\ncheck.matches(\"/form/password\", \"Passwords must match\");\ncheck.lessThan(\"/form/endDate\", \"Must be before end date\");\ncheck.greaterThan(\"/form/startDate\", \"Must be after start date\");\ncheck.requiredIf(\"/form/enableNotifications\", \"Required when enabled\");\n```\n\n## User Prompt Builder\n\nBuild structured user prompts with optional spec refinement and state context:\n\n```typescript\nimport { buildUserPrompt } from \"@json-render/core\";\n\n// Fresh generation\nbuildUserPrompt({ prompt: \"create a todo app\" });\n\n// Refinement with edit modes (default: patch-only)\nbuildUserPrompt({ prompt: \"add a toggle\", currentSpec: spec, editModes: [\"patch\", \"merge\"] });\n\n// With runtime state\nbuildUserPrompt({ prompt: \"show data\", state: { todos: [] } });\n```\n\nAvailable edit modes: `\"patch\"` (RFC 6902 JSON Patch), `\"merge\"` (RFC 7396 Merge Patch), `\"diff\"` (unified diff).\n\n## Spec Validation\n\nValidate spec structure and auto-fix common issues:\n\n```typescript\nimport { validateSpec, autoFixSpec } from \"@json-render/core\";\n\nconst { valid, issues } = validateSpec(spec);\n// issues include: missing_child, invalid_visible (malformed conditions),\n// repeat_without_children, repeat_item_outside_scope, repeat_state_mismatch\n\nconst { spec: fixed, fixDetails } = autoFixSpec(spec);\n// fixDetails entries are { message, lossy }. Lossless fixes relocate\n// misplaced fields; lossy fixes prune dangling children references.\n// In a repair loop, withhold lossy fixes until retries are exhausted:\nconst attempt = autoFixSpec(spec, { lossy: retriesExhausted });\n```\n\n## Visibility Conditions\n\nControl element visibility with state-based conditions. `VisibilityContext` is `{ stateModel: StateModel }`.\n\n```typescript\nimport { visibility } from \"@json-render/core\";\n\n// Syntax\n{ \"$state\": \"/path\" }                    // truthiness\n{ \"$state\": \"/path\", \"not\": true }      // falsy\n{ \"$state\": \"/path\", \"eq\": value }      // equality\n[ cond1, cond2 ]                         // implicit AND\n\n// Helpers\nvisibility.when(\"/path\")                 // { $state: \"/path\" }\nvisibility.unless(\"/path\")               // { $state: \"/path\", not: true }\nvisibility.eq(\"/path\", val)              // { $state: \"/path\", eq: val }\nvisibility.and(cond1, cond2)             // { $and: [cond1, cond2] }\nvisibility.or(cond1, cond2)              // { $or: [cond1, cond2] }\nvisibility.always                        // true\nvisibility.never                         // false\n```\n\n## Built-in Actions in Schema\n\nSchemas can declare `builtInActions` -- actions that are always available at runtime and auto-injected into prompts:\n\n```typescript\nconst schema = defineSchema(builder, {\n  builtInActions: [\n    { name: \"setState\", description: \"Update a value in the state model\" },\n  ],\n});\n```\n\nThese appear in ","tagline":"Core package for defining schemas, catalogs, and AI prompt generation for json-render.
