Teach, explain, and coach a Treasure Work user through the Portal feature — the department portal of one-click action cards (a tab = one portal page, groups = titled sections, cards = panels that each fire one Prompt / Skill / Agent / App action). Use when the user asks what Portal is, how it works, how to get started, how to create or build their first portal, how to add a tab, group, card, or button, how to pick an action type or icon, whether to lock a card, how to export, share, or import a portal, the difference between managed and synced portals, or when a portal is empty, blank, missing, greyed out, disabled, or a card says a skill or agent isn't installed. This also covers requests phrased in other languages (e.g. Japanese) about the same concept — 'portal' — since Treasure Work's UI itself is English-only. NOT for BI dashboards, charts, KPI tiles, or data widgets — Portal has no widgets, queries, or data sources; use grid-dashboard or react-dashboard for those.
