The prompt

Claude

You are a professional writer specialized in producing structured and impactful reports. Write a comprehensive report on the following topic:

Report topic: [describe the precise topic]
Report type: [activity / analysis / project / strategic / audit]
Recipient(s): [senior management / client / team / steering committee]
Main objective: [inform / persuade / recommend / report]
Key data and facts to include: [list important figures, results, observations]
Period covered: [dates or period concerned]
Desired tone: [formal / professional yet accessible / technical]
Desired length: [approximate number of pages or words]

Structure the report with:

  1. A title page with subject, author, date, and recipients
  2. An executive summary of 150-200 words
  3. A table of contents
  4. An introduction setting the context, objectives, and methodology
  5. The body of the report organized into numbered sections with subsections
  6. Tables or bullet lists for numerical data
  7. A section for analysis and interpretation of results
  8. Concrete recommendations ranked by priority
  9. A conclusion summarizing key points
  10. Appendices if necessary

Use precise language, avoid unnecessary jargon, and ensure that each section flows logically. Each recommendation must be actionable and justified by the data presented.

Why it works

This prompt works because it provides Claude with a complete framework: the role (professional writer), the context (type, audience, objective), and a detailed 10-point structure that guides generation section by section. Specifying the recipients and tone allows Claude to automatically adapt the language level and technical detail. Finally, explicit constraints (actionable recommendations, logical flow) elevate the quality of the result by imposing rigorous professional criteria.

Expected result

You get a complete and professional report, structured with a clear hierarchy of numbered sections, a punchy executive summary, and prioritized recommendations. The document is ready to be reviewed, adjusted with your specific data, and formatted in your usual template. The tone and level of detail match the target audience you specified.

FAQ

How can I integrate my own numerical data into the report generated by Claude?
List your data directly in the prompt as bullet points or simple tables. For example: "Revenue Q1: €2.3M (+12%), Q2: €1.8M (-5%)". The more precise and structured your data in the prompt, the more naturally Claude will integrate it into the analysis and recommendations. For large datasets, paste them in the appendix of the prompt and ask Claude to analyze them before writing.
Can Claude adapt the report to a specific company format or template?
Yes, describe your template structure in the prompt: section names, expected order, numbering conventions, and mandatory elements (legal notices, logos, confidentiality clause). You can also paste an example of a previous report and ask Claude to follow the exact same format. Claude will respect the conventions you specify, including heading styles, table formats, and internal terminology.
What is the best approach for writing a very long report (20+ pages) with Claude?
Proceed in several steps. First, ask Claude to produce a detailed outline with headings and subheadings for each section. Validate this outline, then ask for section-by-section writing, reminding the overall context at each step. This iterative approach ensures consistency of the thread while allowing you to refine each part. Finally, ask Claude to proofread the whole document to harmonize style and check data consistency between sections.
