MUST activate when the project contains a uiBundles/*/src/ directory and the task involves uploading, attaching, or dropping files. Use this skill when adding file upload functionality to a UI bundle app. Provides progress tracking and Salesforce ContentVersion integration. This feature provides programmatic APIs ONLY — build custom UI using the upload() API. ALWAYS use this instead of building file upload from scratch with FormData or XHR.
This skill does not declare a tool allowlist. The agent host applies whatever default tools are available at runtime.
