saas-decomposer

saas-decomposer is a skill for Claude Code, Codex from mupengi-bot/mupengism. It costs 98 tokens per session (2,042 once invoked), scanned A, original, MIT.

An analysis workflow for breaking down a SaaS service, meaning software delivered online by subscription, into individual functions. It identifies which functions might be recreated as AI-agent skills and proposes an internal development roadmap.

In plain words
What is it for?
Use it to analyze a SaaS website or name, list and score its functions for AI replacement, map them to existing skills, identify missing skills, and compare an internal build with subscription costs.
Why use it?
It helps determine what an existing online service actually does before attempting to replace parts of it. It also highlights functions that still require new software or infrastructure.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

saas-decomposer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SaaS → AIaaS 전환 분석 엔진
기존 SaaS 서비스를 분해하고, AI 에이전트 스킬로 대체 가능한 영역을 식별하여 내재화 로드맵을 수립합니다.

핵심 개념: SaaS → AIaaS 전환 분석

무펭이즘의 핵심 비전: "SaaS의 종말 → AIaaS"

  • SaaS 시장 $200B가 통째로 뒤집힌다
  • 소프트웨어를 파는 시대에서 AI 노동력을 설치하는 시대로
  • 기존 SaaS의 기능을 분해하여 어떤 부분을 AI 에이전트 스킬로 대체할 수 있는지 분석

기능

1. SaaS 서비스 분해 (Decompose)

입력: SaaS 서비스 URL 또는 이름

프로세스:

  1. web_fetch로 서비스 랜딩페이지/기능페이지 크롤링
  2. 핵심 기능 목록 추출
  3. 각 기능을 원자적 태스크로 분해
  4. AI 대체 가능성 점수 (1-5) 부여
  5. 기존 무펭이 스킬로 커버 가능한 부분 매핑

출력 포맷:

## [서비스명] 분해 결과

### 기능 목록
- 기능A (AI 대체: ⭐⭐⭐⭐⭐) → 기존 스킬: copywriting
- 기능B (AI 대체: ⭐⭐⭐) → 신규 스킬 필요
- 기능C (AI 대체: ⭐) → 인프라 개발 필요

### AI 대체율: 70%
### 필요 신규 스킬: 3개
### 예상 개발 기간: 2주

2. 내재화 계획 (Internalize)

분해 결과를 바탕으로 개발 로드맵 생성:

  • 스킬 개발 우선순위 (대체 효과 높은 것부터)
  • 기존 스킬 재활용 매핑
  • 신규 스킬 스펙 초안 자동 생성
  • 비용 비교: SaaS 구독료 vs 자체 스킬 운영비

예시:

### 내재화 로드맵

#### Phase 1: Quick Wins (1주)
- [기존 스킬 활용] copywriting으로 이메일 템플릿 자동화
- [기존 스킬 활용] auto-reply로 고객 응답 자동화

#### Phase 2: 신규 스킬 개발 (2주)
- lead-scorer: 리드 스코어링 알고리즘
- campaign-optimizer: A/B 테스트 자동화

#### Phase 3: 인프라 (4주)
- 데이터 파이프라인 구축
- 실시간 동기화 시스템

### 비용 비교
- HubSpot Pro: $800/월 → 무펭이 스킬팩: $120/월 (85% 절감)

3. 경쟁 SaaS 비교 분석

같은 카테고리 SaaS 3-5개 동시 분해:

  • 기능 교차 비교표
  • AI 대체 가능 영역 오버랩 분석
  • "우리 스킬팩으로 이 SaaS들을 몇 % 대체 가능한가" 산출

예시:

### 마케팅 SaaS 비교

| 기능 | HubSpot | Mailchimp | ActiveCampaign | 무펭이 대체 |
|------|---------|-----------|----------------|------------|
| 이메일 자동화 | ✅ | ✅ | ✅ | ⭐⭐⭐⭐⭐ auto-reply |
| 리드 스코어링 | ✅ | ❌ | ✅ | ⭐⭐⭐ (신규 스킬) |
| A/B 테스트 | ✅ | ✅ | ✅ | ⭐⭐⭐⭐ copywriting |
| CRM 통합 | ✅ | ⚠️ | ✅ | ⭐⭐ (인프라 필요) |

**종합 대체율**: 65%

4. 산업별 SaaS → AIaaS 전환 템플릿

미리 정의된 산업별 SaaS 분해 패턴:

마케팅
  • SaaS: HubSpot, Mailchimp
  • 무펭이 대체: auto-reply + copywriting + mail + seo-content-planner
프로젝트 관리
  • SaaS: Notion, Jira
  • 무펭이 대체: decision-log + daily-report + git-auto
고객 관리
  • SaaS: Salesforce, Zendesk
  • 무펭이 대체: auto-reply + notification-hub + data-scraper

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
