- Tested on real filings. Each pack ships with sample outputs on real companies, and every number in them is checked against the source document.
- Sources or it didn't happen. Outputs carry source tags that link back to the filing.
- No advice, by design. Skills refuse buy/sell calls, price targets and position sizing.
- Free data first. SEC EDGAR, FRED and whatever you paste in. No paid data feeds required.
- One format, many agents. Built on the open Agent Skills standard.
