## What it does

The skill wires the `@cognite/reveal-widget` npm package into a React and TypeScript Flows app. It walks through the work in order: inspect the project, install the package and its peers, add the `three` and `@cognite/reveal` dedupe entry to Vite, set CSP allowances in `manifest.json`, write a controller class around `RevealWidgetController`, then mount `RevealWidget` inside a container with an explicit height.

Drive the controller imperatively from your own event handlers rather than from a `useEffect` that reacts to prop changes. Resources load either through the model browser (`sdk.models3D.list()` with classic `modelId`/`revisionId`) or from a CDM reference with `externalId` and `space`. Release the handle returned by `addResource` with `.remove()` on selection change and unmount.

Two things to check before you start. The app has to be wrapped in `CogniteSdkProvider` from `@cognite/app-sdk`, since that provider supplies the `CogniteClient` through `useCogniteSdk()`. And set `viewerOptions.useCoreDm` to match where the 3D content actually lives — if the models sit in the classic 3D API while the flag is `true`, the viewer finds nothing. The skill advises pinning `@cognite/reveal` to `4.36.0` instead of the `4.35.3` in the package's declared peer range.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add cognitedata/builder-skills --skill reveal-3d -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/reveal-3d/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/reveal-3d/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add cognitedata/builder-skills --skill reveal-3d -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/reveal-3d/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add cognitedata/builder-skills --skill reveal-3d -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/reveal-3d/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install cognitedata/builder-skills reveal-3d
```

2. **Manually: put the files in place**
- File: `.github/skills/reveal-3d/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add cognitedata/builder-skills --skill reveal-3d -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/cognitedata/builder-skills --path skills/reveal-3d
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/reveal-3d/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add cognitedata/builder-skills --skill reveal-3d -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/cognitedata/builder-skills/tree/HEAD/skills/reveal-3d/SKILL.md

## When to use it
- embed a Cognite Reveal 3D viewer in a Flows app
- show a CAD model or point cloud next to asset data
- open a 360° image collection from CDF
- highlight a Core Data Model instance on a loaded model
- migrate an app off the old copied bundle onto `@cognite/reveal-widget`

## Example prompts
- Add a Reveal 3D viewer to the Flows app for the `selectedEquipment` instance
- Install `@cognite/reveal-widget` and load a model by `modelId` and `revisionId`
- Set up the CSP in `manifest.json` for scenes and 360° images

# Reveal 3D Viewer

Add a Cognite Reveal 3D viewer to a Flows app using the published `@cognite/reveal-widget` npm package. Renders CAD models, point clouds, 360° image collections, and CDF scenes from CDF, with model browsing or direct model/revision IDs.

DM instance to visualize: **$ARGUMENTS**

## Use This When

The user wants to embed an interactive Cognite Reveal viewer for CDF 3D content in a Flows app.

Do **not** use this skill for static diagrams, graph visualizations, or unrelated custom Three.js scenes.

Do **not** use the deprecated app-local "copy the bundle" approach — that pattern (a `src/features/reveal-3d/` folder of copied provider/hook source) is replaced by installing `@cognite/reveal-widget` directly. If an app still has a copied bundle from a prior integration, migrate it to this package rather than extending it.

## Prerequisites

- The app uses React + TypeScript and is wrapped in `@cognite/app-sdk`'s `CogniteSdkProvider` (Flows auth), which supplies the `CogniteClient` (`sdk`) via `useCogniteSdk()` from `@cognite/app-sdk/react`. `@cognite/cli` is the CLI used to scaffold/deploy the app, not the runtime auth library — apps created with `npx @cognite/cli apps create` depend on `@cognite/app-sdk` for this, not `@cognite/cli` itself (the `useDune()`/`@cognite/dune/auth` hook only exists for legacy `--classic` scaffolds).
- The CDF project has 3D models, or the user has supplied direct model/revision IDs or a CDM (`externalId`/`space`) model reference.
- For DM-linked 3D, the instance/model must be identifiable via a CDM `externalId`/`space` pair or a classic `modelId`/`revisionId`; instance highlighting works once a model is loaded and the instance is contextualized (mapped) to it.
