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

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.
