us-stock skillA
us-stock is agent-read markdown (skill) from starchild-ai-agent/official-skills: US stock fundamentals: financials, holders, insiders, earnings, dividends, splits. Use for any US ticker beyond price (e.g. AAPL financials, NVDA top holders, MSFT insider trades, TSLA earnings calendar)..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# 🇺🇸 us-stock — US Equities Data
Single Python module with **multi-source fallback** for US stocks. Mirror of `cn-stock` for the US market. Use whenever the user asks about a US ticker — fundamentals, holders, insiders, financials. For pure price/K-line on US tickers, this skill internally calls the paid TwelveData skill, so you get one consistent interface.
## Architecture
```
your call → exports.py
├─ twelvedata (paid, primary) → realtime quote, time series
└─ yfinance (free, primary for fundamentals)
→ info, holders, insiders,
financials, news, options,
dividends, splits, earnings
```
Most functions return a uniform envelope:
```python
{"ok": bool, "source": str, "data": <payload>, "error": str|None, "ts": int}
```
Exception: `get_full_report(symbol)` returns a combined dict of sub-results (quote/company/holders/insiders/earnings/news).
## Quick Start
**Preferred** — use `core.skill_tools` (handles import isolation):
```bash
python3 - <<'EOF'
from core.skill_tools import _modules
us = _modules["us-stock"]

mdr add starchild-ai-agent/official-skills/us-stock@v1.0.2mdr add starchild-ai-agent/official-skills/us-stock@sha256:6655c54bb5fbe485Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
