The website serves only the latest stable CE.SDK release. It has no older versions. This bundle targets CE.SDK `1.83.0`. If the project uses a different CE.SDK version, read the changelog and upgrade pages, and check the type definitions of the installed package. ## How to Use 1. **Read the index**: Read `references/js.md`. It lists all Vanilla JavaScript pages with their titles and links. 2. **Select pages**: Pick the pages that match the query. 3. **Fetch each page as Markdown**: Remove the trailing `/` from the link and add `.md`. For example, `https://img.ly/docs/cesdk/js/export-save-publish/export/to-png-f87eaf/` becomes `https://img.ly/docs/cesdk/js/export-save-publish/export/to-png-f87eaf.md`. Use WebFetch. If WebFetch is not available (for example in Codex), use `curl -sL <url>`. 4. **Answer from the fetched pages only**: Give the relevant section and code examples, and cite the page URLs. If no page covers the request, say so. Do not fill the gap with pre-trained knowledge. 5. **Check rules**: Before setup, initialization, or common operations, read the local `rules/*.md` files. They list agent pitfalls that the website does not cover. ## API Lookup For TypeScript API queries (method signatures, types, parameters): - Editor API (`@cesdk/cesdk-js`): `https://img.ly/docs/cesdk/js/api/cesdk-js.md` - Engine API (`@cesdk/engine`): `https://img.ly/docs/cesdk/js/api/engine.md` Class and type pages follow the same `.md` rule. For example: `https://img.ly/docs/cesdk/js/api/engine/classes/blockapi.md`. **Tip**: Verify types against the TypeScript definitions — CE.SDK evolves rapidly and type shapes may differ from pre-trained knowledge. ## Full Text `https://img.ly/docs/cesdk/js/llms-full.txt` holds all Vanilla JavaScript pages in one file (several MB). Use it only as a last resort, when the index and the pages do not answer the query. Search it with `curl -sL <url> | grep -n "<keyword>"`. Do not read it in full. ## Local Rules - `rules/asset-handling.md`: Image format recommendations, URI resolution - `rules/common-pitfalls.md`: Critical gotchas (invisible fills, SVG rendering issues) - `rules/content-fill-mode.md`: `contentFillMode` belongs on the block, not the fill - `rules/silent-init-errors.md`: CreativeEditor init callback swallows errors silently - `rules/verify-properties-before-use.md`: Call `engine.block.findAllProperties()` before you get or set a property ## 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. ## Related Skills - Use \`/imgly-sdk:build\` when the user needs implementation help, not just docs - Use \`/imgly-sdk:explain\` for conceptual explanations beyond what docs cover
