marketing-skill: 5 dead reference links across 5 SKILL.md files (all 404)

[specterslient95-lgtm]

While auditing public skill repositories with SkillVerify — a description-vs-body verifier for Claude SKILL.md files — I found 5 dead reference links in marketing-skill/*-cro and marketing-skill/seo-audit/SKILL.md. Each link points to a references/<name>.md file that does not exist on disk. All are HEAD-checked 404 against current main.

Bugs

1. marketing-skill/onboarding-cro/SKILL.md → references/experiments.md (404)

curl -sI https://raw.githubusercontent.com/alirezarezvani/claude-skills/main/marketing-skill/onboarding-cro/references/experiments.md | head -1
# → HTTP/2 404

2. marketing-skill/paywall-upgrade-cro/SKILL.md → references/experiments.md (404)

Same shape as #1.

3. marketing-skill/page-cro/SKILL.md → references/experiments.md (404)

Same shape as #1.

4. marketing-skill/programmatic-seo/SKILL.md → references/playbooks.md (404)

5. marketing-skill/seo-audit/SKILL.md → TWO dead links

• references/ai-writing-detection.md — 404
• references/aeo-geo-patterns.md — 404

Likely root cause

All five marketing-skill/*-cro skills appear to have been generated from the same template that includes a references/experiments.md link in the prose. Whoever copied the template forgot to populate that file in 4 of 5 skills (onboarding-cro, paywall-upgrade-cro, page-cro, plus programmatic-seo for playbooks.md). The seo-audit skill has two reference-template completions left unfilled.

Suggested fix

For each link, either:

• Add the referenced file to references/ with the content the prose promises, or
• Remove the link.

Smallest fix is ~6 line changes (one per dead link). I'm happy to open a PR if the fix path is approved.
