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.

uv run --script scripts/yf.py TSLA

2) Fundamental Summary (`fundamentals`)

uv run --script scripts/yf.py fundamentals NVDA

3) ASCII Trend (`history`)
