Claude · Data Analysis · Common Fixes
You are a exacting editor using Claude for data analysis, specifically decision log.
Job: what we chose and why.
Audience: ops. Constraint: revisit date.
Working style: diagnostic. Optimize for typical failures and how to repair the prompt.
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.Looking for a Claude prompt for decision log? Start here — the common fixes angle focuses on typical failures and how to repair the prompt. Most failed runs trace back to missing audience or success criteria — this prompt adds both. The common fixes version uses diagnostic language and targets typical failures and how to repair the prompt.
When to use this prompt
For Anthropic models, data analysis prompts fail when they mix strategy and execution. This decision log brief separates the job so you can iterate once, not ten times. Swap only nouns when adapting — keep the process intact.
Why this prompt works
- The common fixes angle adds typical failures and how to repair the prompt without extra fluff.
- Repeats the hard constraint: revisit date.
- Uses diagnostic language that matches how practitioners actually brief work.
- Centers what we chose and why so success is observable.
- Separates draft from critique so you can steal the structure later.
How to use it in Claude
Use diagnostic follow-ups only — mixing tones mid-thread confuses Anthropic models. Save the winning variant for decision log — teams with a short library ship faster. Ask for a shorter version after the long one; compression reveals weak claims. For data analysis work, paste claude handles long briefs, policy-aware writing, and stepwise reasoning as a one-line reminder above the prompt. Name the success metric aloud: what we chose and why. If the draft cannot pass it, do not polish prose yet.
Swap the audience once. If the decision log piece still works, the core is solid. 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 Common Fixes output. Anthropic models still need your facts for decision log; they cannot invent metrics or brand rules. analysts and operators teams bookmark slug decision-log-fixes when typical failures and how to repair the prompt matters.
Step-by-step
- Open Claude 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 Claude 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
- Accepting the first draft without checking what we chose and why.
- Asking for decision log plus three other jobs in one message.
- Using the Common Fixes prompt but editing it into a vague one-liner.
Expert notes
Slug decision-log-fixes: a analysts and operators-oriented data analysis brief. Queries, insights, charts, and decision memos. Pair it with one real asset from your portfolio before the second run.
Refresh quarterly: Claude models change. Keep constraints; update examples. Mark the page stale if revisit date no longer matches policy.
