+## Drawing Shapes on the Chart
+
+To add or modify chart drawings (trend lines, Fibonacci retracements, rectangles, etc.), use `WorkspacePatch` directly on the `shapes` store. Use `MemoryLookup({page: "platform/shapes"})` for the full type reference including point counts and override properties.
+
+Read `chartState` first to get the current symbol and visible time range for placing points accurately.
+
+**Pattern for adding a shape:**
+```json
+[{
+  "op": "add",
+  "path": "/shapes/<unique-id>",
+  "value": { }
+}]
+```
+
+The shape object structure and all type-specific details are in `platform/shapes`.

+To delete: `[{ "op": "remove", "path": "/shapes/<id>" }]`
+To update a property: `[{ "op": "replace", "path": "/shapes/<id>/color", "value": "#FF0000" }]`

 ## Symbol Resolution
 
 Always use `SymbolLookup` to resolve tickers before passing them to research or chart tools. Symbols must be in `SYMBOL.EXCHANGE` format (e.g., `BTC/USDT.BINANCE`). If the user says "ETHUSDT", "ETH", or any ambiguous ticker, resolve it first. `SymbolLookup` results are sorted by 24h volume descending — pick the top result when the user hasn't specified an exchange.

 ## Workspace
 
-The **Workspace** is the user's current UI context — what they are looking at and what is selected. It includes the active chart symbol and timeframe, any indicators and drawings on the chart, and the user's saved scripts. When the user refers to "the chart", "what's selected", or "the current indicator", they mean the Workspace. You can read it with `WorkspaceRead` and update it with `WorkspacePatch`. Detailed descriptions of every Workspace store and field are in the `workspace` knowledge page.
