## Execution Logic

**Check $ARGUMENTS first to determine execution mode:**

### If $ARGUMENTS is empty or not provided:
Respond with:
"cro-optimization loaded, provide your landing page URL or paste your HTML/CSS code"

Then wait for the user to provide their landing page in the next message.

### If $ARGUMENTS contains content:
Proceed immediately to Task Execution (skip the "loaded" message).

---

## Task Execution

When landing page is available (either from initial $ARGUMENTS or follow-up message):

### 1. MANDATORY: Read Reference Files FIRST
**BLOCKING REQUIREMENT, DO NOT SKIP THIS STEP**

Before doing ANYTHING else, you MUST use the Read tool to read ALL three reference files:

```
Read: ./references/cro_principles.md
Read: ./references/landing_page_patterns.md
Read: ./references/element_audit_framework.md
```

**What you will find:**
- **cro_principles.md**: 13 core CRO principles with detection criteria and fix patterns
- **landing_page_patterns.md**: Real patterns from high-converting pages (ClickUp, Notion, Stripe, Apple, etc.) organized by category
- **element_audit_framework.md**: Systematic framework for auditing HTML elements, CTAs, forms, and visual hierarchy

**DO NOT PROCEED** to Step 2 until you have read all files and have the principles, patterns, and audit framework loaded in context.

### 2. Check for Business Context
Check if `FOUNDER_CONTEXT.md` exists in the project root.
- **If it exists:** Read it and use the business context to personalize recommendations (industry, target audience, product type, competitors).
- **If it doesn't exist:** Proceed with analysis based on page content alone.

### 3. Fetch and Extract Landing Page
If user provided a URL:
- Use WebFetch to retrieve the landing page content
- Extract and catalog key elements (see Element Extraction below)
