The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
The installer script runs npm ci (scripts/spreadsheet.sh:119) which will fetch and install runtime packages from the npm registry (e.g. https://registry.npmjs.org/exceljs/-/exceljs-4.4.0.tgz), so remote code from those listed resolved URLs in runtime/package-lock.json will be downloaded and used at runtime.
