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 This includes auditing existing resources for broken links and outdated content.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• Auditing for broken or outdated links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 Identify outdated content — Does it use old syntax/patterns?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:

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

Article Sources (Priority Order)

Video Creators (Priority Order)

Course Sources

Quality Criteria

Must Have (Required)

• Link works — Returns 200 (not 404, 301, 5xx)
• JavaScript-focused — Not primarily about C#, Python, Java, etc.
• Technically accurate — No factual errors or anti-patterns
• Accessible — Free or has meaningful free preview

Should Have (Preferred)

• Recent enough — See publication date guidelines below
• Reputable source — From trusted sources list or well-known creator
• Unique perspective — Not duplicate of existing resources
• Appropriate depth — Matches concept complexity
• Good engagement — Positive comments, high views (for videos)

Red Flags (Reject)

Publication Date Guidelines

Rule of thumb: For time-sensitive topics, prefer content from the last 3-5 years. For fundamentals, older classic content is often excellent.

Words and Phrases to Avoid

Words and Phrases That Work

Link Audit Process

Step 1: Check Each Link

For each resource in the concept page:

1. Click the link — Does it load?
2. Note the HTTP status:

Step 2: Content Verification

For each accessible link:

1. Skim the content — Is it still accurate?
2. Check the date — When was it published/updated?
3. Verify JavaScript focus — Is it primarily about JS?
4. Look for red flags — Anti-patterns, errors, outdated syntax

Step 3: Description Review

For each resource:

1. Read current description — Is it specific?
2. Compare to actual content — Does it match?
3. Check for generic phrases — "comprehensive guide", etc.
4. Identify improvements — How can it be more specific?

Step 4: Gap Analysis

After auditing all resources:

1. Count by section — Do we meet targets?
2. Check diversity — Beginner AND advanced? Visual AND text?
3. Identify missing types — No MDN? No videos?
4. Note recommendations — What should we add?

Summary

When curating resources for a concept page:

1. Audit first — Check all existing links and content
2. Identify gaps — Compare against targets (2-4 refs, 4-6 articles, 3-4 videos)
3. Find quality resources — Search trusted sources
4. Write specific descriptions — What's unique + why read/watch
5. Format correctly — Proper Card syntax, icons, ordering
6. Document changes — Use the audit report template

Remember: Resources should enhance learning, not pad the page. Every link should offer genuine value. Quality over quantity — a few excellent resources beat many mediocre ones.
