# Skill: Resource Curator for Concept Pages

Use this skill to find, evaluate, add, and maintain high-quality external resources (articles, videos, courses) for concept documentation pages. This includes auditing existing resources for broken links and outdated content.

## When to Use

- Adding resources to a new concept page
- Refreshing resources on existing pages
- Auditing for broken or outdated links
- Reviewing community-contributed resources
- Periodic link maintenance

## Resource Curation Methodology

Follow these five phases for comprehensive resource curation.

### Phase 1: Audit Existing Resources

Before adding new resources, audit what's already there:

1. **Check link accessibility** — Does each link return 200?
2. **Verify content accuracy** — Is the content still correct?
3. **Check publication dates** — Is it too old for the topic?
4. **Identify outdated content** — Does it use old syntax/patterns?
5. **Review descriptions** — Are they specific or generic?

### Phase 2: Identify Resource Gaps

Compare current resources against targets:

| Section | Target Count | Icon |
|---------|--------------|------|
| Reference | 2-4 MDN links | `book` |
| Articles | 4-6 articles | `newspaper` |
| Videos | 3-4 videos | `video` |
| Courses | 1-3 (optional) | `graduation-cap` |
| Books | 1-2 (optional) | `book` |

Ask:
- Are there enough resources for beginners AND advanced learners?
- Is there visual content (diagrams, animations)?
- Are official references (MDN) included?
- Is there diversity in teaching styles?

### Phase 3: Find New Resources

Search trusted sources using targeted queries:

**For Articles:**
```
[concept] javascript tutorial site:javascript.info
[concept] javascript explained site:freecodecamp.org
[concept] javascript site:dev.to
[concept] javascript deep dive site:2ality.com
[concept] javascript guide site:css-tricks.com
```

**For Videos:**
```
YouTube: [concept] javascript explained
YouTube: [concept] javascript tutorial
YouTube: jsconf [concept]
YouTube: [concept] javascript fireship
YouTube: [concept] javascript web dev simplified
```

**For MDN:**
```
[concept] site:developer.mozilla.org
[API name] MDN
```

### Phase 4: Write Descriptions

Every resource needs a specific, valuable description:

**Formula:**
```
Sentence 1: What makes this resource unique OR what it specifically covers
Sentence 2: Why reader should click (what they'll gain, who it's best for)
```

### Phase 5: Format and Organize

- Use correct Card syntax with proper icons
- Order resources logically (foundational first, advanced later)
- Ensure consistent formatting
