  Look up CE.SDK Vanilla JavaScript reference docs, guides, and configuration pages.

  Use when the user needs CE.SDK docs for Vanilla JavaScript — configuration, UI customization,
  export options, feature guides, or getting-started instructions. Also triggered by "IMG.LY", "CreativeEditor",
  "CE.SDK", or "cesdk" when the user needs an existing Vanilla JavaScript doc page.

  Not for writing code (use build) or concept explanations (use explain).

  <example>
  Context: User asks about Vanilla JavaScript configuration
  user: "How do I configure the editor in Vanilla JavaScript?"
  assistant: "I'll use /cesdk:docs-js to look up configuration options."
  </example>

  <example>
  Context: User needs vanilla JS setup
  user: "How do I use CE.SDK without a framework?"
  assistant: "Let me use /cesdk:docs-js to find the relevant documentation."
  </example>

# CE.SDK Vanilla JavaScript Documentation

Look up documentation for IMG.LY CreativeEditor SDK (Vanilla JavaScript).

**Query**: $ARGUMENTS

## How to Use

1. **Index lookup**: Match the query to a path in the Documentation Index above.
   The index uses compressed format: `dir:{file1.md,file2.md}` means files are at
   `dir/file1.md` and `dir/file2.md`.
   Resolve the path using Glob: `**/skills/docs-js/<path>.md`
   (e.g., for `text/add.md` → `**/skills/docs-js/text/add.md`)
2. **Search**: If no exact match exists, use Grep to search the documentation:
   `Grep pattern="<keyword>" path="**/skills/docs-js/" output_mode="content"`
   or search filenames: `Glob pattern="**/skills/docs-js/**/*<keyword>*.md"`
3. **Read and respond** with the relevant section and code examples
4. **Check rules** if the topic involves setup, initialization, or common
   operations: `**/skills/docs-js/rules/*.md`

## API Lookup

For TypeScript API queries (method signatures, types, parameters):

1. **Module lookup**: Match the query to a module in the API index above.
   Read the module file: `**/skills/docs-js/api/<ModuleName>.md`
   (e.g., for BlockAPI → `**/skills/docs-js/api/BlockAPI.md`)
2. **Method search**: If looking for a specific method, use Grep:
   `Grep pattern="<method>" path="**/skills/docs-js/api/" output_mode="content"`
3. **For common types**: Read `**/skills/docs-js/api/types.md`

**Tip**: Verify types against the TypeScript definitions — CE.SDK evolves rapidly and type shapes may differ from pre-trained knowledge.

## Quick Reference

| API modules | `api/BlockAPI.md`, `api/SceneAPI.md`, etc. |

## Additional Triggers

This skill also covers queries about CE.SDK block types, asset sources, and feature capabilities.
It handles API method lookups — BlockAPI, SceneAPI, EditorAPI, AssetAPI, method signatures,
return types, and "engine.block" style queries.
