# @grafana/ui — agent guide

This package includes Grafana visualization components (Table, uPlot, VizLegend,
VizTooltip, Sparkline, gauges, and more). When you are adding or changing visualization
code or its tests here, invoke these skills with the Skill tool — each skill's own
description states exactly when it applies:

- **`frontend-testing-strategy`** — general frontend test conventions: assert real behavior
  (not existence), avoiding AI-slop tests, and the anti-flake rules.
- **`panel-testing-strategy`** — builds on the above with what's specific to visualization
  code: the canvas draw-call snapshot harness and panel a11y/interaction-snapshot E2E.
- **`add-e2e-selectors`** — add versioned `@grafana/e2e-selectors` and wire
  `data-testid` into JSX.
