What's inside (it's genuinely useful)

✓
The 4-question confidentiality pre-flight
The ten-second check that keeps client data — and your licence — safe before any AI task.
✓
10 copy-paste prompts for finance work
Lender narratives, variance commentary, transaction anomaly flags, CRA-notice translation, tiered pricing, forecast stress-tests, and more.
✓
A "verify before you send" note on every prompt
Because the prompt is the easy part — the professional judgment on the output is the job.
