What it does

Requirement Summarizer is an agent skill from ArabelaTso/Skills-4-SE. Extract and summarize core features, constraints, and priorities from requirement documents. Use when analyzing PRDs, RFCs, business requirements, user stories, epics, or any requirement documentation to identify must-have features, technical constraints, priority levels (P0/P1/P2/MoSCoW), and key decision points. Triggers when users ask to summarize, analyze, extract, or understand requirements from documents.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Product & Project Management, covering User stories, PRD writing and Prioritization frameworks. The repository describes itself as: A curated list of 180+ useful Claude Skills for Software Engineering and resources for customizing AI for SE workflows. The licence is Apache-2.0.

When your agent uses it

  • Business requirements
  • Any requirement documentation to identify must-have features
  • Technical constraints
  • Priority levels (P0/P1/P2/MoSCoW)

Example prompts

  • “/requirement-summarizer”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Read and Understand the Document
  2. Extract Key Information
  3. Generate Structured Summary
  4. Quality Checks
  5. Handle Edge Cases

What it can do on your machine

Read from SKILL.md and the folder at commit 4f38503. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Requirement Summarizer loads about 1.8k tokens when it runs. Until then it costs about 109 tokens; SKILL.md has 612 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~109
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Requirement Summarizer

Overview

Extract and organize the essential information from requirement documents into a structured markdown summary that highlights core features, constraints, and priorities.

Workflow

Follow these steps to summarize requirement documents:

1. Read and Understand the Document

First, read the entire requirement document to understand its structure and content:

  • Identify document type (PRD, RFC, user story, business requirement, etc.)
  • Note any existing structure (sections, headers, numbering)
  • Understand the context and scope of the requirements
2. Extract Key Information

Systematically identify and extract:

Core Features:

  • Main functionality being proposed or required
  • User-facing capabilities
  • System behaviors and interactions
  • Integration points with other systems

Constraints:

  • Technical limitations or requirements
  • Business constraints (budget, timeline, resources)
  • Regulatory or compliance requirements
  • Compatibility or platform constraints
  • Security or privacy requirements
  • Performance requirements (latency, throughput, scalability)

Priorities:

  • Explicit priority labels (P0, P1, P2, Critical, High, Medium, Low)
  • MoSCoW categorization (Must have, Should have, Could have, Won't have)
  • MVP vs future phases
  • Required vs optional features
  • Blocking vs non-blocking items
3. Generate Structured Summary

Create a markdown report with the following structure:

markdown
# Requirements Summary: [Document Name]

## Document Metadata
- **Source**: [Document title/filename]
- **Type**: [PRD/RFC/User Story/Business Requirement/etc.]
- **Date Analyzed**: [Current date]

## Executive Summary
[2-3 sentence overview of what this requirement document defines]

## Core Features

### [Feature Category 1]
- **[Feature Name]**: [Brief description]
  - Priority: [P0/P1/P2 or Must/Should/Could]
  - Notes: [Any relevant context]

### [Feature Category 2]
...

## Constraints

### Technical Constraints
- [Constraint description]
- [Constraint description]

### Business Constraints
- [Constraint description]
- [Constraint description]

### Compliance/Regulatory Constraints
- [Constraint description]

### Performance Constraints
- [Constraint description]

## Priority Breakdown

### Critical/Must-Have (P0)
1. [Feature/requirement]
2. [Feature/requirement]

### High Priority/Should-Have (P1)
1. [Feature/requirement]
2. [Feature/requirement]

### Medium Priority/Could-Have (P2)
1. [Feature/requirement]
2. [Feature/requirement]

### Future/Won't-Have (P3)
1. [Feature/requirement]

## Key Decisions & Open Questions
- **Decision**: [What needs to be decided]
  - Options: [If applicable]
  - Impact: [Why this matters]

- **Open Question**: [Unclear requirement or missing information]

## Success Criteria
[How will we know this is successful? Metrics, acceptance criteria, or outcomes]

## Dependencies
- [External dependencies or prerequisites]
- [Related systems or teams]

## Timeline & Milestones
- [Key dates if mentioned in requirements]
- [Phase breakdown if applicable]
4. Quality Checks

Before presenting the summary, verify:

  • Completeness: All major features, constraints, and priorities captured
  • Clarity: Each item is clearly described without ambiguity
  • Accuracy: Information faithfully represents the source document
  • Organization: Related items grouped logically
  • Priorities: Priority levels are consistently applied
  • Actionability: Summary provides clear understanding of what needs to be built
5. Handle Edge Cases

Multiple conflicting priorities:

  • Note conflicts in "Key Decisions & Open Questions"
  • Flag for stakeholder clarification

Implicit vs explicit priorities:

  • If priorities aren't explicitly stated, infer from context (deadline pressure, business value, user impact)
  • Mark inferred priorities with "(inferred)" notation

Vague or ambiguous requirements:

  • Capture them in "Open Questions"
  • Suggest clarifying questions

Missing information:

  • Note gaps in "Open Questions"
  • Highlight critical missing details

Best Practices

Be concise but comprehensive:

  • Capture essential details without copying entire paragraphs
  • Use bullet points for scanability
  • Link back to specific sections of source document if helpful

Maintain objectivity:

  • Extract what's written, not what should be written
  • Flag concerns or gaps but don't rewrite requirements

Prioritize based on evidence:

  • Use explicit priority markers from the document
  • When inferring, base on business value, user impact, dependencies, and timeline

Adapt to document type:

  • PRDs/RFCs: Focus on technical details, system design, and architecture constraints
  • Business requirements: Emphasize business value, ROI, stakeholder needs
  • User stories: Extract acceptance criteria, user journeys, and UX requirements
  • Epics: Break down into constituent stories and themes

Handle different priority systems:

  • P0/P1/P2/P3 (common in tech)
  • Critical/High/Medium/Low
  • MoSCoW (Must/Should/Could/Won't)
  • Phase 1/2/3 or MVP/Future
  • Convert between systems when helpful for clarity

Example Usage

User request:

"Summarize the requirements from this PRD and identify what's critical for the first release"

Response approach:

  1. Read the PRD document
  2. Extract all features, noting which are marked for MVP/Phase 1
  3. Identify technical and business constraints
  4. Map explicit and implicit priorities
  5. Generate structured markdown summary
  6. Highlight critical items for first release in Priority Breakdown section

User request:

"What are the main features and constraints in these user stories?"

Response approach:

  1. Read all user stories
  2. Group related stories by feature theme
  3. Extract acceptance criteria as feature details
  4. Identify technical constraints from story details
  5. Note priorities if labeled (or infer from sprint assignment)
  6. Generate summary organized by feature theme

Tips for Effective Summarization

  • Look for patterns: Similar requirements may be scattered; group them logically
  • Read between the lines: Performance needs, security concerns may be implicit
  • Note what's missing: Gaps in requirements are as important as what's present
  • Preserve traceability: Link summary items back to source sections when possible
  • Stay neutral: Don't judge requirement quality, just extract and organize
  • Be specific: "Fast API response" → "API response time < 200ms"
