Date Tracking Implementation Summary

✅ What Was Implemented

1. Frontmatter Template Update

All 946 skills now have the date_added: "2025-02-26" field in their SKILL.md frontmatter:

---
name: skill-name
description: "Description"
date_added: "2025-02-26"
---

2. Web App Integration

Home Page (Skill List Cards)

• Each skill card now displays a small date badge: 📅 YYYY-MM-DD
• Shows alongside the risk level
• Clean, compact format in the bottom metadata section

Example card now shows:

Risk: safe        📅 2025-02-26

Skill Detail Page

• Date appears as a green badge near the top with other metadata
• Format: 📅 Added YYYY-MM-DD
• Shown alongside Category, Source, and Star buttons

3. Validators Updated

Both validators now accept and validate the date_added field:

• validate-skills.js: Added to ALLOWED_FIELDS
• validate_skills.py: Added YYYY-MM-DD format validation
  • Warns (dev mode) or fails (strict mode) on missing dates
  • Validates format strictly

4. Index Generation

• generate_index.py updated to include date_added in skills.json
• All 946 skills now have dates in the web app index
• Dates are properly exported to web app's /public/skills.json

5. Documentation

• SKILL_TEMPLATE.md: New template for creating skills with date field included
• SKILLS_DATE_TRACKING.md: Complete usage guide for date management
• SKILL_ANATOMY.md: Updated with date_added field documentation
• README.md: Updated contribution guide to mention date tracking

6. Script Tools

✅ All scripts handle UTF-8 encoding on Windows:

• manage_skill_dates.py: Add, update, list skill dates
• generate_skills_report.py: Generate JSON report with dates
• Both handle emoji output correctly on Windows

📊 Current Status

• ✅ 946/946 skills have date_added: "2025-02-26"
• ✅ 100% coverage of date tracking
• ✅ Web app displays dates on all skill cards
• ✅ Validators enforce format (YYYY-MM-DD)
• ✅ Reports available via CLI tools
