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.
Inputs
| Input | Required | Format |
|---|---|---|
| Document text or excerpt | Yes | Pasted text, extracted notes, OCR |
| Document type | Recommended | Proposal, policy, memo, research, etc. |
| Audience | Recommended | Executive, manager, student, team |
| Desired length | Optional | 5 bullets, one page, detailed brief |
| Focus area | Optional | Risks, obligations, actions, decisions |
Output
## Document Summary - [Document Name]
### One-Line Takeaway
[Core point]
### Key Points
- [Point backed by source]
### Actions / Decisions
| Item | Owner | Deadline | Source Note |
|------|-------|----------|-------------|
### Risks / Caveats

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)
| Check | Question |
|---|---|
| Correctness | Are all summarized claims traceable to the document text? |
| Completeness | Are key points, actions, deadlines, risks, and review needs captured? |
| Context-fit | Does the summary match the audience and intended decision? |
| Consequence | What 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.
