Cursor usa o mesmo esquema mcpServers que o Claude Desktop. Config de projeto vence a global.

Casos de uso

Usos do mundo real: marketingskills

Run a proper CRO experiment cycle on a landing page

👤 Growth teams, founders optimizing funnels ⏱ ~60 min intermediate

Quando usar: Your landing page converts at 2%, and you want to A/B test your way to 4%.

Pré-requisitos

Skills installed — git clone https://github.com/coreyhaines31/marketingskills ~/.claude/skills/marketingskills
Current page source accessible — Either in repo or via URL

Fluxo

Hypothesis

Use marketingskills/cro. Analyze /landing/index.html. Propose 3 high-impact experiment hypotheses with expected lift.✓ Copiado

→ Hypotheses reference specific page elements and behavioral data
Design A/B

For hypothesis 1, design the variant. Sample size? Runtime? Kill criteria?✓ Copiado

→ Complete experiment spec with stats
Readout

Experiment ran 14 days, B beat A by 18% on signup. Interpret — is this real? What's next?✓ Copiado

→ Sober readout with statistical and business reasoning

Resultado: An experiment shipped with discipline, not vibes.

Armadilhas

Peeking at data mid-experiment and calling early — Pre-commit to sample size; skill enforces this in prompts

Combine com: filesystem

Refresh landing-page copy in your brand voice

👤 Founders between copywriter hires ⏱ ~30 min beginner

Quando usar: Copy feels generic, you know your voice, you don't have time to write it all.

Pré-requisitos

Brand voice samples — 2–3 paragraphs you know sound right

Fluxo

Pin voice

Use marketingskills/copy. Here are 3 voice samples: <samples>. Profile my voice.✓ Copiado

→ Voice profile: vocabulary, rhythm, attitude
Rewrite

Rewrite /landing/index.html headline, subheadline, and CTAs in my voice. Three variations each.✓ Copiado

→ Variants that sound like the samples
Pressure test

Which variant survives the "would I actually say this out loud" test? Defend.✓ Copiado

→ One winner picked with reasoning

Resultado: Copy that sounds like you wrote it on a good day.

Armadilhas

Voice drift when asking for length changes — Re-pin the voice samples before every round

Combine com: humanizer-skill

Solução de problemas

Erros comuns e correções

Generic hypothesis output

Copy still sounds AI

Run humanizer-skill as a second pass

Event taxonomy conflicts with existing events

Provide current schema; skill will propose additions, not a full rewrite

Alternativas

marketingskills vs. outros

Alternativa	Quando usar	Troca
Hire a fractional CMO	Stakes are high and you want human judgment	Expensive; slower
Point-tool SaaS (Optimizely, VWO)	You want full experimentation platforms	Paid; less integrated with your code
