Credential Fixture Review

python scripts/_env_constants.py is review material for the Stock Information Explorer skill. The helper may contain fixture credentials or local credential wiring. Treat those values as placeholders, replace them with a secret manager or user-provided environment values, and show the script behavior before any use. Do not contact external services with embedded sample credentials.

Stock Information Explorer

This skill fetches OHLCV data from Yahoo Finance via yfinance and computes technical indicators locally (no API key required).

3) ASCII Trend (`history`)

Data quality may vary by ticker/market (e.g., missing volume for some symbols).
