## What it does

The skill walks a SAC custom widget from brief to upload artifacts. It starts by classifying the widget role and data-source mode, suggests a few role-aware options, then generates the chosen package. SAC-bound widgets get asked for dimensions, measures, dates, versions and feed order; pure UI controls get interaction, navigation, state, method and event requirements instead.

Bundled templates cover widgets, charts and KPI cards, plus `templates/local-builder/` — static HTML/CSS/vanilla JS with no public CDNs. That builder exports two artifacts separately: `widget.json` and a Resource-ZIP holding only root-level component JavaScript. If direct `file://` access is blocked, a Node fallback `server.mjs` runs instead.

You need a SAC tenant with Optimized Story Experience or Analytics Designer, plus JavaScript and Web Components knowledge. Hosting is either external (GitHub Pages, AWS S3, Azure) or SAC-hosted resources. The skill points to SAP's official docs and a samples repository, and asks you to confirm technical IDs, feed mappings and asset rights before it writes code.

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/secondsky/sap-skills/tree/HEAD/plugins/sap-sac-custom-widget/skills/sap-sac-custom-widget/SKILL.md

## When to use it
- build a custom visualization SAC does not ship
- wire ECharts, D3.js or Chart.js into a widget
- set up data binding through feeds and field order
- keep the styling panel and builder panel in separate files
- export `widget.json` and a Resource-ZIP for SAC import

## Example prompts
- Build a SAC custom widget for a sales-by-region chart with data coming through feeds
- Create a KPI card as a Web Component with a styling panel and a builder panel
- Prepare `widget.json` and the Resource-ZIP for uploading the widget to SAC
