Extract Requirements Target

Overview

Read the source material, separate signals from background, and produce a compact summary focused on two outputs only: Requirements and Target. Preserve the user's intent, compress repetition, and avoid inventing missing requirements.

Extraction Workflow

1. Identify the document type

• Detect whether the input is a technical plan, architecture note, requirement doc, meeting summary, product brief, or mixed working draft.
• Assume that key facts may appear in scattered sections, lists, tables, or informal notes.
• Ignore decorative language, status updates, and background explanation unless they change scope or intent.

2. Extract Requirements

• Extract what must be done, delivered, satisfied, supported, avoided, or constrained.
• Include explicit needs such as functional requirements, technical constraints, dependencies, success criteria, deadlines, compatibility expectations, compliance rules, or non-functional requirements.
• Merge duplicate statements into one concise line.
• Prefer concrete wording over generic restatements.
• Keep each requirement independently scannable.

3. Extract Target

• Infer the end-state the author wants to achieve.
• Express the target as the final business, technical, delivery, or decision objective.
• Distinguish the target from implementation detail:
  • Requirement answers "what is needed or constrained?"
  • Target answers "what outcome is this document trying to achieve?"
• Prefer one short paragraph or 1 to 3 tight bullets.

4. Resolve ambiguity carefully

• Mark items as inferred only when the source implies them but does not state them directly.
• Do not upgrade assumptions into facts.
• If the document contains multiple competing goals, separate:
  • primary target
  • secondary target
• If the source is too vague, say that the target is unclear and list the strongest likely interpretation.

Compression Rules

• Reduce long paragraphs into short, information-dense statements.
• Remove examples, anecdotes, rationale, and history unless they materially affect the requirement or target.
• Avoid copying the user's prose when a shorter equivalent is clearer.
• Keep terminology from the source when it is domain-critical.
• Preserve quantities, versions, deadlines, environments, and named systems when present.

Output Format

Use this structure by default:

## Requirements
- ...
- ...

## Target
...

If the source is complex, add one optional section:

## Notes
- Inferred: ...
- Missing detail: ...

Extraction Heuristics

• Treat "need", "must", "should", "expect", "goal", "want", "deliver", "support", "avoid", and "success" as strong requirement signals.
• Treat "so that", "in order to", "最终", "目标", "希望", and "achieve" as strong target signals.
• When the document mixes problem statement and solution proposal, extract requirements from the problem and target from the intended outcome.
• When the document is highly technical, keep platform names, environment names, interfaces, and operational constraints.

Quality Bar

• Make the result understandable without rereading the original document.
• Prefer completeness over oversimplification, but stop before turning the summary back into a full document.
• Keep the final output concise enough that a teammate can understand the ask in under one minute.

Example Triggers

• "Extract the real requirements and target from this RFC."
• "Read this technical note and give me only Requirements and Target."
• "This document is too long. Summarize the需求和目标."
• "从这份方案里提炼需求和目标，不要展开解释。"
