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:

1. Crawl service landing/feature pages with web_fetch
2. Extract core function list
3. Decompose each function into atomic tasks
4. Assign AI replaceability score (1-5)
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%

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)

---

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
