saas-decomposer

SaaS → AIaaS Conversion Analysis Engine
Decomposes existing SaaS services and identifies areas replaceable by AI agent skills to establish internalization roadmap.

Core Concept: SaaS → AIaaS Conversion Analysis

Mupengism's core vision: "End of SaaS → AIaaS"

The entire $200B SaaS market is flipping
From selling software era to installing AI labor era
Analyze which parts of existing SaaS functions can be replaced by AI agent skills

Features

1. SaaS Service Decomposition (Decompose)

Input: SaaS service URL or name

Process:

Crawl service landing/feature pages with web_fetch
Extract core function list
Decompose each function into atomic tasks
Assign AI replaceability score (1-5)
Map coverage by existing Mupeng skills

Output Format:

## [Service Name] Decomposition Results

### Function List
- Function A (AI replacement: ⭐⭐⭐⭐⭐) → Existing skill: copywriting
- Function B (AI replacement: ⭐⭐⭐) → New skill needed
- Function C (AI replacement: ⭐) → Infrastructure development needed

### AI Replacement Rate: 70%
### New Skills Needed: 3
### Estimated Development Time: 2 weeks

2. Internalization Plan

Generate development roadmap based on decomposition results:

Skill development priority (highest replacement effect first)
Map existing skill reuse
Auto-generate new skill spec drafts
Cost comparison: SaaS subscription vs self-skill operation

Example:

### Internalization Roadmap

#### Phase 1: Quick Wins (1 week)
- [Use existing skill] Automate email templates with copywriting
- [Use existing skill] Automate customer responses with auto-reply

#### Phase 2: New Skill Development (2 weeks)
- lead-scorer: Lead scoring algorithm
- campaign-optimizer: A/B test automation

#### Phase 3: Infrastructure (4 weeks)
- Build data pipeline
- Real-time sync system

### Cost Comparison
- HubSpot Pro: $800/mo → Mupeng skillpack: $120/mo (85% savings)

3. Competitive SaaS Comparative Analysis

Simultaneous decomposition of 3-5 SaaS in same category:

Function cross-comparison table
AI replacement area overlap analysis
"What % of these SaaS can our skillpack replace" calculation

Example:

### Marketing SaaS Comparison

| Function | HubSpot | Mailchimp | ActiveCampaign | Mupeng Replacement |
|----------|---------|-----------|----------------|-------------------|
| Email automation | ✅ | ✅ | ✅ | ⭐⭐⭐⭐⭐ auto-reply |
| Lead scoring | ✅ | ❌ | ✅ | ⭐⭐⭐ (new skill) |
| A/B testing | ✅ | ✅ | ✅ | ⭐⭐⭐⭐ copywriting |
| CRM integration | ✅ | ⚠️ | ✅ | ⭐⭐ (infrastructure needed) |

**Overall Replacement Rate**: 65%

4. Industry-specific SaaS → AIaaS Conversion Templates

Pre-defined industry-specific SaaS decomposition patterns:

Analysis Framework

1. Crawl      — Collect service functions (web_fetch + data-scraper)
2. Decompose  — Break into atomic tasks
3. Score      — AI replaceability score (1-5)
4. Map        — Map to existing Mupeng skills
5. Gap        — Identify missing skills
6. Plan       — Generate development roadmap
7. Compare    — Cost comparison (SaaS vs AIaaS)

Usage Examples

Basic Decomposition

User: "Decompose HubSpot"
→ Execute Crawl + Decompose + Score + Map
→ Output decomposition results report

Internalization Plan Generation

User: "What do I need to replace Notion with AI?"
→ Execute Decompose + Internalize
→ Output roadmap + cost comparison

Competitive Analysis

User: "Compare marketing SaaS"
→ Simultaneously analyze HubSpot, Mailchimp, ActiveCampaign
→ Cross-comparison table + replacement rate calculation

AI Replaceability Score Criteria

Score	Meaning	Examples
⭐⭐⭐⭐⭐	Immediately replaceable (use existing skills)	Auto email response, content generation
⭐⭐⭐⭐	Replaceable with lightweight skill development (1-2 weeks)	Lead scoring, A/B testing
⭐⭐⭐	Medium development needed (2-4 weeks)	Workflow engine, dashboard
⭐⭐	Infrastructure development needed (1-2 months)	Real-time sync, data pipeline
⭐	Long-term R&D needed (3+ months)	Advanced ML models, complex integrations

Troubleshooting

When web_fetch Fails

Take snapshot with browser tool and analyze
Prioritize crawling public docs (help center, pricing page)

When Competitor Info Insufficient

Reference industry templates first
Utilize similar category SaaS patterns

When Cost Comparison Data Missing

Crawl pricing pages
Estimate industry average subscription fees
