Keep the raw calculation separate from your interpretation. When birth time is unknown, omit every step that depends on houses, Ascendant, Midheaven, or angles.
Step 1Check the raw birth inputs
Verify date, local time, time source, city, coordinates, and historical timezone. A wrong input makes every later paragraph irrelevant.
Step 2Confirm the calculation settings
Check tropical or sidereal zodiac, house system, node type, aspect list, and orb rules. Compare only calculators using matching settings.
Step 3Cross-check core placements
Verify the Sun, Moon, Ascendant if known, chart ruler, and major aspects with a deterministic calculator.
Step 4Demand exact evidence
For each important claim, ask which placement or transit supports it and what the orb is. Reject evidence that does not appear in the chart.
Step 5Look for invented certainty
Flag guaranteed events, diagnoses, death claims, secret feelings, cheating claims, wealth promises, or instructions to ignore professional advice.
Step 6Test alternatives
Ask whether the same factor could have several expressions and whether the reading acknowledges context and birth-time uncertainty.
Step 7Record usefulness separately from truth
A prompt can be useful without being factually predictive. Keep that distinction explicit.
Quality checks
- Never paste passwords, identity documents, or unrelated private data into a model.
- Use a nickname when possible.
- Check the provider’s data policy.
- Report errors with the exact placement and expected result.
Frequently asked questions
Why does AI invent astrology placements?
Language models predict likely text and may complete a plausible chart instead of performing a reliable astronomical calculation.
Is a reading correct because it feels accurate?
No. Broad or suggestive statements can feel personal. Verify the underlying data and keep alternative explanations in view.
What is the safest AI astrology architecture?
Deterministic calculation first, structured evidence second, constrained interpretation third, and review plus safety controls before display.
