feat: Implement intelligent auto-categorization for skills
- Added `scripts/auto_categorize_skills.py` to analyze skill names and descriptions, auto-assigning categories based on keyword matching. - Updated category distribution to show counts and sort categories by skill count in the Home page dropdown. - Created documentation in `docs/CATEGORIZATION_IMPLEMENTATION.md` and `docs/SMART_AUTO_CATEGORIZATION.md` detailing the new categorization process and usage. - Introduced `scripts/fix_year_2025_to_2026.py` to update all skill dates from 2025 to 2026. - Enhanced user experience by moving "uncategorized" to the bottom of the category list and displaying skill counts in the dropdown.

# Smart Categorization Implementation - Complete Summary
|
||||
|
||||
## ✅ What Was Done
|
||||
|
||||
### 1. **Intelligent Auto-Categorization Script**
|
||||
Created [scripts/auto_categorize_skills.py](scripts/auto_categorize_skills.py) that:
|
||||
- Analyzes skill names and descriptions
|
||||
- Matches against keyword libraries for 13 categories
|
||||
- Automatically assigns meaningful categories
|
||||
- Removes "uncategorized" bulk assignment
|
||||
|
||||
**Results:**
|
||||
- ✅ 776 skills auto-categorized
|
||||
- ✅ 46 already had categories preserved
|
||||
- ✅ 124 remaining uncategorized (edge cases)
|
||||
|
||||
### 2. **Category Distribution**
|
||||
|
||||
**Before:**
|
||||
```
|
||||
uncategorized: 926 (98%)
|
||||
game-development: 10
|
||||
libreoffice: 5
|
||||
security: 4
|
||||
```
|
||||
|
||||
**After:**
|
||||
```
|
||||
Backend: 164 ████████████████
|
||||
Web Dev: 107 ███████████
|
||||
Automation: 103 ███████████
|
||||
DevOps: 83 ████████
|
||||
AI/ML: 79 ████████
|
||||
Content: 47 █████
|
||||
Database: 44 █████
|
||||
Testing: 38 ████
|
||||
Security: 36 ████
|
||||
Cloud: 33 ███
|
||||
Mobile: 21 ██
|
||||
Game Dev: 15 ██
|
||||
Data Science: 14 ██
|
||||
Uncategorized: 126 █
|
||||
```
|
||||
|
||||
### 3. **Updated Index Generation**
|
||||
Modified [scripts/generate_index.py](scripts/generate_index.py):
|
||||
- **Frontmatter categories now take priority**
|
||||
- Falls back to folder structure if needed
|
||||
- Generates clean, organized skills_index.json
|
||||
- Exported to web-app/public/skills.json
|
||||
|
||||
### 4. **Improved Web App Filter**
|
||||
|
||||
**Home Page Changes:**
|
||||
- ✅ Categories sorted by skill count (most first)
|
||||
- ✅ "Uncategorized" moved to bottom
|
||||
- ✅ Each shows count: "Backend (164)", "Web Dev (107)"
|
||||
- ✅ Much easier to navigate
|
||||
|
||||
**Updated Code:**
|
||||
- [web-app/src/pages/Home.jsx](web-app/src/pages/Home.jsx) - Smart category sorting
|
||||
- Sorts categories by count using categoryStats
|
||||
- Uncategorized always last
|
||||
- Displays count in dropdown
|
||||
|
||||
### 5. **Categorization Keywords** (13 Categories)
|
||||
|
||||
| Category | Key Keywords |
|
||||
|----------|--------------|
|
||||
| **Backend** | nodejs, express, fastapi, django, server, api, database |
|
||||
| **Web Dev** | react, vue, angular, frontend, css, html, tailwind |
|
||||
| **Automation** | workflow, scripting, automation, robot, trigger |
|
||||
| **DevOps** | docker, kubernetes, ci/cd, deploy, container |
|
||||
| **AI/ML** | ai, machine learning, tensorflow, nlp, gpt, llm |
|
||||
| **Content** | markdown, documentation, content, writing |
|
||||
| **Database** | sql, postgres, mongodb, redis, orm |
|
||||
| **Testing** | test, jest, pytest, cypress, unit test |
|
||||
| **Security** | encryption, auth, oauth, jwt, vulnerability |
|
||||
| **Cloud** | aws, azure, gcp, serverless, lambda |
|
||||
| **Mobile** | react native, flutter, ios, android, swift |
|
||||
| **Game Dev** | game, unity, webgl, threejs, 3d, physics |
|
||||
| **Data Science** | pandas, numpy, analytics, statistics |
|
||||
|
||||
### 6. **Documentation**
|
||||
Created [docs/SMART_AUTO_CATEGORIZATION.md](docs/SMART_AUTO_CATEGORIZATION.md) with:
|
||||
- How the system works
|
||||
- Using the script (`--dry-run` and apply modes)
|
||||
- Category reference
|
||||
- Customization guide
|
||||
- Troubleshooting
|
||||
|
||||
## 🎯 The Result
|
||||
|
||||
### No More Uncategorized Chaos
|
||||
- **Before**: 98% of 946 skills lumped as "uncategorized"
|
||||
- **After**: 87% properly organized, only 13% needing review
|
||||
|
||||
### Better UX
|
||||
1. **Smarter Filtering**: Categories sorted by relevance
|
||||
2. **Visual Cues**: Shows count "(164 skills)""
|
||||
3. **Uncategorized Last**: Put bad options out of sight
|
||||
4. **Meaningful Groups**: Find skills by actual function
|
||||
|
||||
### Example Workflow
|
||||
User wants to find database skills:
|
||||
1. Opens web app
|
||||
2. Sees filter dropdown: "Backend (164) | Database (44) | Web Dev (107)..."
|
||||
3. Clicks "Database (44)"
|
||||
4. Gets 44 relevant SQL/MongoDB/Postgres skills
|
||||
5. Done! 🎉

# Smart Auto-Categorization Guide
|
||||
|
||||
## Overview
|
||||
|
||||
The skill collection now uses intelligent auto-categorization to eliminate "uncategorized" and organize skills into meaningful categories based on their content.
|
||||
|
||||
## Current Status
|
||||
|
||||
✅ **946 total skills**
|
||||
- 820 skills in meaningful categories (87%)
|
||||
- 126 skills still uncategorized (13%)
|
||||
- 11 primary categories
|
||||
- Categories sorted by skill count (most first)
|
||||
|
||||
## Category Distribution
|
||||
|
||||
| Category | Count | Examples |
|
||||
|----------|-------|----------|
|
||||
| Backend | 164 | Node.js, Django, Express, FastAPI |
|
||||
| Web Development | 107 | React, Vue, Tailwind, CSS |
|
||||
| Automation | 103 | Workflow, Scripting, RPA |
|
||||
| DevOps | 83 | Docker, Kubernetes, CI/CD, Git |
|
||||
| AI/ML | 79 | TensorFlow, PyTorch, NLP, LLM |
|
||||
| Content | 47 | Documentation, SEO, Writing |
|
||||
| Database | 44 | SQL, MongoDB, PostgreSQL |
|
||||
| Testing | 38 | Jest, Cypress, Unit Testing |
|
||||
| Security | 36 | Encryption, Authentication |
|
||||
| Cloud | 33 | AWS, Azure, GCP |
|
||||
| Mobile | 21 | React Native, Flutter, iOS |
|
||||
| Game Dev | 15 | Unity, WebGL, 3D |
|
||||
| Data Science | 14 | Pandas, NumPy, Analytics |
|
||||
|
||||
## How It Works
|
||||
|
||||
### 1. **Keyword-Based Analysis**
|
||||
The system analyzes skill names and descriptions for keywords:
|
||||
- **Backend**: nodejs, express, fastapi, django, server, api, database
|
||||
- **Web Dev**: react, vue, angular, frontend, css, html, tailwind
|
||||
- **AI/ML**: ai, machine learning, tensorflow, nlp, gpt
|
||||
- **DevOps**: docker, kubernetes, ci/cd, deploy
|
||||
- And more...
|
||||
|
||||
### 2. **Priority System**
|
||||
Frontmatter category > Detected Keywords > Fallback (uncategorized)
|
||||
|
||||
If a skill already has a category in frontmatter, that's preserved.
|
||||
|
||||
### 3. **Scope-Based Matching**
|
||||
- Exact phrase matches weighted 2x higher than partial matches
|
||||
- Uses word boundaries to avoid false positives
|
||||
|
||||
## Using the Auto-Categorization
|
||||
|
||||
### Run on Uncategorized Skills
|
||||
```bash
|
||||
python scripts/auto_categorize_skills.py
|
||||
```
|
||||
|
||||
### Preview Changes First (Dry Run)
|
||||
```bash
|
||||
python scripts/auto_categorize_skills.py --dry-run
|
||||
```
|
||||
|
||||
### Output
|
||||
```

```
|
||||
|
||||
## Web App Improvements
|
||||
|
||||
### Category Filter
|
||||
**Before:**
|
||||
- Unordered list including "uncategorized"
|
||||
- No indication of category size
|
||||
|
||||
**After:**
|
||||
- Categories sorted by skill count (most first, "uncategorized" last)
|
||||
- Shows count: "Backend (164)" "Web Development (107)"
|
||||
- Much easier to browse
|
||||
|
||||
### Example Dropdowns
|
||||
|
||||
**Sorted Order:**
|
||||
1. All Categories
|
||||
2. Backend (164)
|
||||
3. Web Development (107)
|
||||
4. Automation (103)
|
||||
5. DevOps (83)
|
||||
6. AI/ML (79)
|
||||
7. ... more categories ...
|
||||
8. Uncategorized (126) ← at the end
|
||||
|
||||
## For Skill Creators
|
||||
|
||||
### When Adding a New Skill
|
||||
|
||||
Include category in frontmatter:
|
||||
```yaml
|
||||
---
|
||||
name: my-skill
|
||||
description: "..."
|
||||
category: web-development
|
||||
date_added: "2025-02-26"
|
||||
---
|
||||
```
|
||||
|
||||
### If You're Not Sure
|
||||
|
||||
The system will automatically categorize on next index regeneration:
|
||||
```bash
|
||||
python scripts/generate_index.py
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Customization
|
||||
|
||||
### Add Custom Keywords
|
||||
|
||||
Edit [scripts/auto_categorize_skills.py](scripts/auto_categorize_skills.py):
|
||||
|
||||
```python
|
||||
CATEGORY_KEYWORDS = {
|
||||
'your-category': [
|
||||
'keyword1', 'keyword2', 'exact phrase', 'another-keyword'
|
||||
],
|
||||
# ... other categories
|
||||
}
|
||||
```
|
||||
|
||||
Then re-run:
|
||||
```bash
|
||||
python scripts/auto_categorize_skills.py
|
||||
python scripts/generate_index.py
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "Failed to categorize" Skills
|
||||
|
||||
Some skills may be too generic or unique. You can:
|
||||
|
||||
1. **Manually set category** in the skill's frontmatter:
|
||||
```yaml
|
||||
category: your-chosen-category
|
||||
```
|
||||
|
||||
2. **Add keywords** to CATEGORY_KEYWORDS config
|
||||
|
||||
3. **Move to folder** if it fits a broader category:
|
||||
```
|
||||
skills/backend/my-new-skill/SKILL.md
|
||||
```
|
||||
|
||||
### Regenerating Index
|
||||
|
||||
After making changes to SKILL.md files:
|
||||
```bash
|
||||
python scripts/generate_index.py
|
||||
```
|
||||
|
||||
This will:
|
||||
- Parse frontmatter categories
|
||||
- Fallback to folder structure
|
||||
- Generate new skills_index.json
|
||||
- Copy to web-app/public/skills.json
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Test in web app**: Try the improved category filter
|
||||
2. **Add missing keywords**: If certain skills are still uncategorized
|
||||
3. **Organize remaining 126**: Either auto-assign or manually review
|
||||
4. **Monitor growth**: Use reports to track new vs categorized skills
|
||||
|
||||
---
|
||||
|
||||
**Result**: Much cleaner category filter with smart, meaningful organization! 🎉
