When to Use

  • Summarizing long documents that are not formal business reports.
  • Extracting key points from policies, proposals, PDFs, research notes, or document packets.
  • Preparing a quick readout before deciding whether to read the full document.
  • Comparing multiple documents for themes, contradictions, or action items.

Procedure

Step 1 - Identify Document Type

Classify the source: policy, proposal, memo, research, contract-like document, transcript, academic paper, operating document, or mixed packet.

Step 2 - Extract Core Content

Capture:

  • purpose
  • main claims or findings
  • dates, parties, obligations, or deadlines
  • decisions requested
  • open questions
  • risks or caveats

Step 3 - Separate Summary From Interpretation

Keep source-backed summary separate from analysis or recommendation. Mark anything inferred.

Step 4 - Produce Audience-Specific Output

Adapt format for executive, manager, student, legal/compliance reviewer, or team member.

Step 5 - Add Reading Guidance

State which sections deserve human review and why.

Quality Criteria

  • The summary stays faithful to the document and does not invent missing facts.
  • Important dates, obligations, numbers, and decisions are preserved.
  • Source-backed summary is separated from interpretation.
  • The output states what was not reviewed or could not be verified.
  • High-risk documents are flagged for expert review.

Verification (4C)

CheckQuestion
CorrectnessAre all summarized claims traceable to the document text?
CompletenessAre key points, actions, deadlines, risks, and review needs captured?
Context-fitDoes the summary match the audience and intended decision?
ConsequenceWhat could be misread if the user relies only on the summary?

Edge Cases

  • OCR or extraction errors - Flag low confidence and avoid definitive claims.
  • Legal, financial, or compliance content - Summarize only and recommend expert review before acting.
  • Multiple documents conflict - Show a contradiction table instead of choosing a winner.
  • Very long packet - Summarize by section and list skipped or unread portions.

Examples

Prompt: "Summarize this vendor proposal for an operations manager. Focus on deliverables, pricing assumptions, risks, and questions for the vendor."

Good pattern: "The proposal assumes customer data export is available by June 1. This is a dependency, not a confirmed commitment."

Definition of Done

  • The user can decide whether to read the full document.
  • Important actions and risks are visible.
  • Uncertainty and review needs are explicit.

Changelog
