Cro Optimization
This one loads three reference files with actual CRO principles, high-converting landing page patterns from companies like Stripe and Notion, and a systematic audit framework, then runs your page through all of them. You give it a URL or paste HTML, it catalogs every element (H1s, CTAs, forms, trust signals), flags what violates the 13 principles, compares against proven patterns, and spits out prioritized fixes with before/after examples. The output format is thorough, maybe even verbose, but that's the point. It checks for a FOUNDER_CONTEXT.md file to personalize recommendations if you've documented your business. Good for when you need specific rewrites and implementation steps, not just "make your CTA clearer" handwaving.

CRO Optimization
Purpose
Analyze a landing page and deliver a comprehensive CRO audit with specific, actionable recommendations to maximize conversions.
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
