Replace per-tool rule trees (.cursor/rules, .claude/rules, .codex/rules) with a single wiki/architecture/ source — 11 pages + README — readable as plain markdown by any agent. Canonical skills live in .agents/skills/; .claude/skills, .cursor/skills, .codex/skills are directory symlinks. AGENTS.md is the entrypoint (rewritten as a lean overview, no per-tool path lists). CLAUDE.md, GEMINI.md, and .github/copilot-instructions.md all point to it. Add open-pr skill (uses .github/pull_request_template.md as the source of truth for the PR body) and remove the dangling .claude/CLAUDE.md relative symlink.

# Node Schemas
|
|
|
|
*Node type definitions, Zod schema pattern, and how to create nodes in the scene.*
|
|
|
|
Applies to: `packages/core/src/schema/**`.
|
|
|
|
All node types are defined as Zod schemas in `packages/core/src/schema/nodes/`. Each schema extends `BaseNode` and exports both the schema and its inferred TypeScript type.
|
|
|
|
**Sources**: `packages/core/src/schema/base.ts`, `packages/core/src/schema/nodes/`
|
|
|
|
## BaseNode
|
|
|
|
Every node shares these fields:
|
|
|
|
```ts
|
|
{
|
|
object: 'node' // always literal 'node'
|
|
id: string // typed ID e.g. "wall_abc123"
|
|
type: string // node type discriminator e.g. "wall"
|
|
name?: string // optional display name
|
|
parentId: string | null // parent node ID; null = root
|
|
visible: boolean // defaults to true
|
|
metadata: Record<string, unknown> // arbitrary JSON, defaults to {}
|
|
}
|
|
```
|
|
|
|
## Defining a New Node Type
|
|
|
|
```ts
|
|
// packages/core/src/schema/nodes/my-node.ts
|
|
import { z } from 'zod'
|
|
import { BaseNode, objectId, nodeType } from '../base'
|
|
|
|
export const MyNode = BaseNode.extend({
|
|
id: objectId('my-node'), // generates IDs like "my-node_abc123"
|
|
type: nodeType('my-node'), // sets literal type discriminator
|
|
// add node-specific fields:
|
|
width: z.number().default(1),
|
|
label: z.string().optional(),
|
|
}).describe('My node — one-line description of what it represents')
|
|
|
|
export type MyNode = z.infer<typeof MyNode>
|
|
export type MyNodeId = MyNode['id']
|
|
```
|
|
|
|
Then add `MyNode` to the `AnyNode` union in `packages/core/src/schema/types.ts`.
|
|
|
|
## Creating Nodes in Tools
|
|
|
|
Always use `.parse()` to validate and generate a proper typed ID. Never construct a plain object manually.
|
|
|
|
```ts
|
|
import { WallNode } from '@pascal-app/core'
|
|
import { useScene } from '@pascal-app/core'
|
|
|
|
// 1. Parse validates and fills defaults (including auto-generated id)
|
|
const wall = WallNode.parse({ name: 'Wall 1', start: [0, 0], end: [5, 0] })
|
|
|
|
// 2. createNode(node, parentId?) inserts it into the scene
|
|
const { createNode } = useScene.getState()
|
|
createNode(wall, levelId)
|
|
```
|
|
|
|
For batch creation:
|
|
|
|
```ts
|
|
const { createNodes } = useScene.getState()
|
|
createNodes([
|
|
{ node: WallNode.parse({ start: [0, 0], end: [5, 0] }), parentId: levelId },
|
|
{ node: WallNode.parse({ start: [5, 0], end: [5, 4] }), parentId: levelId },
|
|
])
|
|
```
|
|
|
|
## Updating Nodes
|
|
|
|
```ts
|
|
const { updateNode } = useScene.getState()
|
|
updateNode(wall.id, { height: 2.8 }) // partial update, merges with existing
|
|
```
|
|
|
|
## Real Examples
|
|
|
|
- **Simple geometry node**: `packages/core/src/schema/nodes/wall.ts` — `start`, `end`, `thickness`, `height`
|
|
- **Polygon node**: `packages/core/src/schema/nodes/slab.ts` — `polygon: [number, number][]`, `holes`
|
|
- **Positioned node**: `packages/core/src/schema/nodes/item.ts` — `position`, `rotation`, `scale`, `asset`
|
|
|
|
## Rules
|
|
|
|
- **Always use `.parse()`** — it generates the correct ID prefix and fills defaults. `WallNode.parse({...})` not `{ type: 'wall', id: '...' }`.
|
|
- **Never hardcode IDs.** Let `objectId('type')` generate them.
|
|
- **Add new node types to `AnyNode`** in `types.ts` or they won't be accepted by the store.
|
|
- **Keep schemas in `packages/core`**, not in the viewer or editor — the schema is shared by all packages.
