## Skills vs Projects vs MCP connectors {#stack}

Layer

What it is

Best for Shopify CRO

**Chat only**

One-off prompts

Brainstorms, weak consistency

**Project + files**

Brand voice, past tests, screenshots

Repeatable audits

**Skill (`SKILL.md`)**

Named procedure Claude loads on intent

Same CRO job every week

**MCP / custom connector**

Tools that read/write external systems

Live products, theme git, design tokens

**Claude Code + Shopify toolkit**

Dev-oriented loop

Liquid, Admin GraphQL, CLI ([setup guides](https://www.fudge.ai/guides/shopify-ai-toolkit-claude-code-setup/))

**Rule of thumb:** Skills encode _judgment_. Connectors encode _access_. CRO quality needs both.

Anthropic frames skills as reusable instructions that pair with connectors so Claude knows _how_ to use tools, not only _that_ tools exist ([skills guide](https://resources.anthropic.com/hubfs/The-Complete-Guide-to-Building-Skill-for-Claude.pdf)).

## How to install a Shopify skill {#install}

Exact UI labels move; the pattern stays stable:

1.  Create a Project named `Shopify CRO, {Store}`.
2.  Upload brand kit: voice, banned claims, shipping/returns truth, top 20 SKUs, last 3 test winners.
3.  Add one skill file per job (or a monorepo of skills Claude can select).
4.  Optional: attach MCP connectors for Admin read, theme repo, Figma/design system.
5.  Run a dry-run skill on a **staging** theme or CSV export before production writes.

**Minimal skill skeleton**

-   Name: `shopify-pdp-rewrite`
-   When to use: improve product page conversion or rewrite a PDP
-   Inputs: product title, current description, price, top objections, brand voice file
-   Steps: extract claims needing proof → rewrite benefit-first without medical/income guarantees → output A/B variants + hypothesis → list theme sections to change
-   Never: invent reviews, fake scarcity, or change legal pages without human approval

* * *

## The 10 CRO skills (copy-ready briefs) {#ten}

Each skill below is a **job description** you paste into a skill file. Tune names to your stack (Klaviyo, Triple Whale, GA4, Shopify Analytics).

### 1\. CRO Agent (master triage)

**Job:** Turn messy store symptoms into a ranked experiment backlog.

**Inputs:** last 28d sessions, add-to-cart rate, checkout start/complete, top landing templates, 5 session recordings or heat summaries.

**Outputs:**

-   10 opportunities scored by impact × effort
-   3 test hypotheses with primary metric
-   "Do not test" list (brand/legal)

**Prompt spine:** "You are the CRO lead for a Shopify brand. Prefer fewer high-confidence tests over 20 micro-copy nits."

### 2\. PDP copy rewriter

**Job:** Rewrite product description for conversion without hype violations.

**Inputs:** current body HTML, materials, sizing, who it is _not_ for, top 10 review themes.

**Outputs:** short above-the-fold, bullets, FAQ answers, schema-friendly plain text, A/B body.

**Guardrails:** no disease claims, no "guaranteed results," match [Meta ads policy](/blog/meta-ads-policy-guide-2026) tone if the same copy feeds ads.

### 3\. Theme / Liquid tweak brief

**Job:** Translate a CRO idea into a developer-ready theme brief.

**Inputs:** theme name, target template (`product`, `collection`, `index`), desired UX change, mobile screenshot.

**Outputs:** acceptance criteria, Liquid/section files likely touched, risks (app conflicts), QA checklist.

**Pairs with:** Claude Code + Shopify skills for Liquid/Admin ([developer-oriented skill packs](https://www.get-ryze.ai/blog/claude-shopify-skills) exist in the wild; write your own for your theme).

### 4\. Checkout friction finder

**Job:** Find drop-off causes between cart and paid order.

**Inputs:** checkout funnel steps, payment methods, shipping zones, common support tickets ("where's my order," address fails).

**Outputs:** friction table, quick wins (copy, defaults, express pay), experiments needing eng.

### 5\. Collection page IA auditor

**Job:** Fix collection merchandising and filters that hide product-market fit.

**Inputs:** collection URL, product count, filter config, top search queries (Shopify + site search).

**Outputs:** sort default recommendation, filter prune list, hero product rules, internal link suggestions to [Shopify SEO](/blog/shopify-seo-complete-guide-2026) priorities.

### 6\. Offer and urgency compliance check

**Job:** Review banners, timers, and discount language before they tank trust or ads.

**Inputs:** current promo bar, discount codes, landing hero.

**Outputs:** pass/fail on honesty (real end dates), stacked discount risk, ad-safe rewrite.

### 7\. Review mining → social proof blocks

**Job:** Turn reviews into on-page proof modules.

**Inputs:** CSV or app export of reviews, star mix, photo reviews flag.

**Outputs:** 8 quote cards by objection, PDP insert locations, UGC ad angles (hand to Meta creative).

### 8\. Speed / LCP triage for theme

**Job:** Prioritize performance work that affects conversion.

**Inputs:** PageSpeed or CrUX summary, app list, hero media types.

**Outputs:** ranked fixes (image, app remove/defer, font), "measure after" checklist. Does not replace a full performance eng audit.

### 9\. Refund and return pattern analysis

**Job:** Spot product or expectation gaps that destroy LTV.

**Inputs:** refund reasons, SKU-level return rate, PDP claims.

**Outputs:** top 5 claim mismatches, PDP/FAQ fixes, SKUs to pause ads on.

### 10\. Inventory × ads spend guardrail

**Job:** Stop paid traffic when stock or margin reality breaks.

**Inputs:** inventory by SKU, ad spend by product (or campaign map), margin floor.

**Outputs:** kill list, budget reallocation notes, alert rules for weekly ops.

**Connects to paid:** use with [Meta manager workflows](/blog/meta-ads-manager-workflows-2026) and [API automation](/blog/meta-ads-agency-workflow-automation) so creative CPA work does not ignore stock.

## Custom connector MCP for web design {#mcp-design}

Searchers looking for **claude custom connector mcp for web design** usually want Claude to:

1.  Read a design system (tokens, components)
2.  Inspect a theme or front-end repo
3.  Propose or apply layout changes with less copy-paste

### Pattern A, Design system connector

-   MCP server exposes components, spacing, type scale
-   Skill: "Only use tokens from the design system; flag one-off CSS"
-   Output: section specs that match existing UI kit

### Pattern B, Theme git connector

-   Read-only first: list sections, schemas, locales
-   Skill: produce PR description + diff plan
-   Write path only on staging branch with human merge

### Pattern C, Shopify Admin / Storefront connectors

Community and vendors wire Shopify to Claude via MCP custom connectors (Desktop → Settings → Connectors → add URL). Examples of the pattern appear in public writeups ([Composio Shopify → Claude](https://composio.dev/toolkits/shopify/framework/claude-cowork), merchant Reddit threads, store MCP products). Prefer **least privilege** tokens.

### Pattern D, Marketing MCP alongside store MCP

For ads-side work, keep Meta separate: [Best MCP for Meta Ads](/blog/best-mcp-for-meta-ads) and Enrich [/mcp](/mcp) for Helena. Do not overload one connector with Admin write + ads spend pause without separate approvals.

**Web design skill add-on (paste)**

-   Name: `shopify-section-from-design`
-   When: Figma notes or new landing section
-   Require: design tokens file or MCP design connector
-   Steps: map layout to existing sections → list new blocks → mobile breakpoints → accessibility labels → avoid one-off dead CSS
-   Stop if brand fonts/colors missing

* * *

## Safe operating rules on live stores {#safety}

1.  **Staging theme** for visual changes; publish with a human.
2.  **Read-only Admin** until skills are trusted.
3.  **No silent price or inventory writes.**
4.  **Log every connector call** that mutates data.
5.  **Separate skills** for legal pages (refund, shipping) with lawyer/ops review.
6.  **Export-first CRO** (CSV + screenshots) still beats a half-broken MCP.
7.  **App conflict check** before removing scripts for speed.
8.  **Ad copy and PDP claims stay consistent** with policy reality.

## When to use an AI marketing agent instead {#agent}

Claude skills shine for **documentable, repeatable store jobs**. An always-on marketing agent helps when you need:

-   Multi-channel monitoring (ads + SEO + social) without opening five UIs
-   Draft → approve → act loops on a schedule
-   Shared memory across specialists

Helena is Enrich Labs' digital marketing agent for that layer: [/ai-digital-marketing-agent](/ai-digital-marketing-agent). For Claude-vs-agent positioning on ads, see [Helena vs Claude for marketing](/blog/helena-vs-claude-for-marketing).

* * *

## Example: one PDP rewrite cycle (end-to-end)

1.  Export product JSON or copy body HTML.
2.  Run **PDP rewriter** skill with review themes.
3.  Run **offer compliance** on the new urgency line.
4.  Run **theme Liquid brief** for where the FAQ block lives.
5.  Staging theme preview on mobile.
6.  Publish; annotate experiment in CRO Agent backlog.
7.  If ads use the same claim set, align Meta creative to avoid policy mismatches ([policy guide](/blog/meta-ads-policy-guide-2026)).

## FAQ {#faq}

### What is a Claude skill for Shopify?

A reusable instruction file that tells Claude how to run one store job (CRO audit, PDP rewrite, theme brief) with fixed inputs, steps, and hard stops.

### Is there a Claude Shopify code skill?

Yes in practice: teams package Liquid, Admin GraphQL, CLI, and metafield procedures as skills or Claude Code workflows. Pair with official Shopify docs and staging, not blind production edits. See community [Shopify AI Toolkit / Claude Code](https://community.shopify.com/t/shopify-ai-toolkit-q-a-running-your-store-with-claude-code/607320) discussions.

### What is a Claude custom connector MCP for web design?

A Model Context Protocol server registered in Claude as a custom connector so Claude can call design-system or repo tools while a skill governs how those tools are used ([MCP connector docs](https://platform.claude.com/docs/en/agents-and-tools/mcp-connector)).

### Do I need MCP to get CRO value?

No. CSV exports, screenshots, and strong skills already move conversion. MCP reduces copy-paste once process is stable.

### Can Claude edit my live theme automatically?

Only if you wire write tools and allow it. Default to staging + human merge.

### How is this different from ChatGPT custom GPTs?

Similar idea (bundled instructions + files). Claude's skills + MCP connector model is oriented toward tool use and agentic workflows; pick the stack your team already operates.

### Should agencies build one mega-skill?

No. Ten sharp skills beat one 4,000-line blob. Share a core pack per client brand kit.

### Where do ads fit?

Inventory × ads skill plus Meta MCP/agent workflows. Store CRO without media feedback is half a system.

### How does Helena relate?

Helena runs broader marketing execution; Claude skills are an excellent _storefront and content craft_ layer you can keep in-repo.

### What should I build first?

CRO Agent + PDP rewriter + offer compliance. Add connectors after two weeks of clean manual runs.

* * *

## The bottom line

**Claude shopify code skill** demand is really demand for _repeatable ecommerce engineering judgment_. **Custom connector MCP for web design** demand is demand for _grounded layout work_. Ship ten small CRO skills, add MCP only where access removes friction, and keep humans on publish and spend.

Start from the skill skeleton above, wire your brand kit, and run the weekly loop. When you want the always-on multi-channel layer, bring in [Helena](https://agent.enrichlabs.ai/marketing/register).
