+## Strategy Metadata Format
+
+When writing or editing a strategy (`category="strategy"`), always include a `metadata` object with:
+
+- **`data_feeds`** — list of feed descriptors the strategy requires:
+  ```json
+  [
+    {"symbol": "BTC/USDT.BINANCE", "period_seconds": 3600, "description": "Primary BTC/USDT hourly feed"},
+    {"symbol": "ETH/USDT.BINANCE", "period_seconds": 3600, "description": "ETH/USDT hourly for correlation"}
+  ]
+  ```
+  `period_seconds` must match what the strategy code expects. Use the same values when calling `backtest_strategy`.
+
+- **`parameters`** — object documenting every configurable parameter in the strategy:
+  ```json
+  {
+    "rsi_length":  {"default": 14,   "description": "RSI lookback period in bars"},
+    "overbought":  {"default": 70,   "description": "RSI level above which position is closed"},
+    "oversold":    {"default": 30,   "description": "RSI level below which long entry is triggered"},
+    "stop_pct":    {"default": 0.02, "description": "Stop-loss as a fraction of entry price (e.g. 0.02 = 2%)"}
+  }
+  ```
+  Include every parameter that appears as a constant in the strategy's `__init__` or class body — use the actual default values from the code.
+
+Example `python_write` call for a strategy:
+```json
+{
+  "category": "strategy",
+  "name": "RSI Mean Reversion",
+  "description": "Long when RSI crosses above oversold; exit when overbought or stop hit",
+  "code": "...",
+  "metadata": {
+    "data_feeds": [
+      {"symbol": "BTC/USDT.BINANCE", "period_seconds": 3600, "description": "BTC/USDT hourly OHLCV + order flow"}
+    ],
+    "parameters": {
+      "rsi_length": {"default": 14, "description": "RSI lookback period"},
+      "overbought":  {"default": 70, "description": "Exit long above this RSI level"},
+      "oversold":    {"default": 30, "description": "Enter long below this RSI level"}
+    }
+  }
+}
+```

 ## Coding Loop Pattern
 
 When a user requests analysis:

-2. **Use the provided name**: The instruction will begin with `Research script name: "<name>"`. Always use that exact name when calling `category_write` or `category_edit`. Check first with `category_read` — if the script already exists, use `category_edit` to update it rather than creating a new one with `category_write`.
