Job: what we chose and why.
Audience: ops. Constraint: revisit date.
Working style: plain and encouraging. Optimize for first successful run with safe defaults.
Process:
1. Restate the brief in one sentence and list missing facts as questions.
2. Draft the artifact.
3. Stress-test it against the constraint.
4. Return a final version plus 3 numbered improvements.
Output contract: use headings, short paragraphs, and concrete examples. No filler. No invented statistics.
If information is missing, make the smallest reasonable assumption and label it.Use this Gemini data analysis template when ops need decision log with the rule: revisit date. Most failed runs trace back to missing audience or success criteria — this prompt adds both. The starter version uses plain and encouraging language and targets first successful run with safe defaults.
When to use this prompt

Why this prompt works

- Asks for a self-check pass, which cuts hallucinated details.
How to use it in Gemini
Redact client names; keep structure. Slug decision-log-starter is your canonical URL for this brief. When ops review output, they should see first successful run with safe defaults without hunting for it. Ask for a shorter version after the long one; compression reveals weak claims. If the first answer is vague, reply with the constraint again: revisit date. For data analysis work, paste gemini is useful for research synthesis, workspace-style tasks, and multimodal briefs as a one-line reminder above the prompt.
Run a constrained version and a wild version of decision log. Keep structure from one and energy from the other. For decision log in data analysis, the failure mode is usually no example. This prompt blocks that by design — especially "revisit date". Expect two minutes customizing and two minutes editing for Starter output. Google models still need your facts for decision log; they cannot invent metrics or brand rules. analysts and operators teams bookmark slug decision-log-starter when first successful run with safe defaults matters.
Step-by-step
- Open Gemini and paste the prompt block unchanged.
- Replace placeholders with your project facts (ops, offer, timeline).
- Confirm the constraint is still visible: revisit date.
- If output is vague, ask Gemini to restate assumptions as questions first.
- Reply with one fix list, then regenerate the final version only.
Example output
Example output shape: H1 with Decision Log, 3 short sections, bullet list of recommendations, closing line that states revisit date. Facts you supply appear; nothing invented.
Common mistakes
- Asking for decision log plus three other jobs in one message.
- Using the Starter prompt but editing it into a vague one-liner.
- Pasting confidential data instead of redacted placeholders.
