Date Tracking Implementation Summary

This note explains how date_added support fits into the current repository structure after the apps/ and tools/ refactor.

What Exists Today

Frontmatter support

New skills can include a date_added field in SKILL.md frontmatter:

---
name: skill-name
description: "Description"
date_added: "2026-03-06"
---

Validator support

The active validators understand date_added:

• tools/scripts/validate_skills.py checks the YYYY-MM-DD format.
• Supporting JS validation/test helpers are aware of the field where relevant.

Index and web app support

• tools/scripts/generate_index.py exports date_added into skills_index.json.
• npm run app:setup copies the generated index to apps/web-app/public/skills.json.
• The web app can render the field anywhere the UI surfaces it.

Maintenance scripts

• tools/scripts/manage_skill_dates.py manages skill dates.
• tools/scripts/generate_skills_report.py produces JSON reports from current skill metadata.

Canonical Documentation

The canonical docs for date tracking now live here:

• skills-date-tracking.md
• ../contributors/skill-template.md
• ../contributors/skill-anatomy.md

Use those files as the source of truth instead of older root-level doc names.

Common Commands

# View current date coverage
python tools/scripts/manage_skill_dates.py list

# Add missing dates
python tools/scripts/manage_skill_dates.py add-missing

# Update one skill
python tools/scripts/manage_skill_dates.py update skill-name 2026-03-06

# Generate a report
python tools/scripts/generate_skills_report.py --output reports/skills_report.json

Notes

• Repository-wide coverage can change over time as new community skills are added, so this document avoids hardcoding counts.
• date_added is useful metadata, but the operational contributor gate remains npm run validate; strict validation is a separate hardening target for legacy cleanup.
