Same command for any agent — swap --agent for codex, cursor, copilot.

# Chart Annotation Skill ## When to use You want to call out a technical level, a pattern, or an event on a stock's price chart. Drawing directly on the chart is almost always clearer than describing it in prose. Reach for this skill whenever you would otherwise say "look at the level around 205" or "notice the downtrend from October to December". **MarketView** is the app's live, TradingView-style price chart page (pan, zoom, switch timeframes). You do **not** need the user to be on it to annotate. If they are, the drawing appears on their live chart immediately. If they are in any other chat, the same drawing renders as a clickable preview card that expands into MarketView — so annotate freely whenever it helps, then mention the user can click it to open the full chart. This skill provides two tools: - `draw_chart_annotation` — add a single annotation to a chart. - `manage_chart_annotations` — list, remove, or clear annotations. ## Interactive chart vs. a Python chart (deliverable) There are two ways to show price information visually — pick by what the user needs: - **This skill (interactive).** Annotations land on the live, pannable MarketView chart (or a preview card that open

How do I install it?

Where does this skill come from?
From ginlix-ai/LangAlpha, a repository with 1,604 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
