Add another file (resource) to an EXISTING dataset in a PortalJS portal — a data dictionary, methodology, or an additional data file. Turns a single-file dataset into a multi-resource one; the showcase renders a section per resource.

After editing `datasets.json` to add a resource to PortalJS dataset `health-stats`, running `npx next build` fails with a JSON syntax parse error. What is the required resolution before reporting completion?
| Checked | Without skill | With skill |
|---|---|---|
| Re-opens datasets.json to fix the syntax error | Missed | Passed |
| Re-runs npx next build to verify the build succeeds before reporting success | Missed | Passed |
The instructions your model reads when the skill loads.
Add a resource — an additional file — to a dataset that already exists in a
portaljs-catalog portal. Where /portaljs-add-dataset creates a new dataset
(one file), this skill adds a file to an existing one: a data dictionary, a
methodology document, or another data file (e.g. a second year's figures).
Mirrors the Frictionless Data Package model: a dataset holds a resources[] array,
and the showcase at /@<namespace>/<slug> renders one section per resource (preview,
schema, download). A single-file dataset migrates to resources[] automatically the
first time a second file is added — no data is lost.
