# The Fly stock screening

Use `screen_stocks` to produce a bounded market-cap-ranked shortlist, then research only the names the user selects or the small number required by the request.

## Procedure

1. The submitted ChatGPT tool supports only `sortBy: "market_cap"`. If the user asks for sector, valuation, growth, or other filtering, explain that this v1 tool cannot apply that filter instead of inventing one.
2. Always bound the request with `page` and `pageSize`; use a small page size for conversational use.
3. Use the typed ChatGPT request shape. Example descending market-cap ordering:

```json
{
  "sortBy": "market_cap",
  "direction": "desc",
  "page": 1,
  "pageSize": 5
}
```

4. Report the market-cap sort direction and page bounds alongside the shortlist.
5. Use `research_company` only for the final selected names, not every row in a broad screen.

## Interpretation rules

- Treat screener values as point-in-time market data and retain relevant dates when available.
- Highlight only fields actually returned by the tool; do not infer missing sector, valuation, growth, yield, return, or leverage filters.
- Do not claim the screen is exhaustive when pagination or selection caps apply.
- A screen is research output, not a recommendation or trade instruction.
