conversion-optimizer

A specialist for conversion rate optimization (CRO), the practice of helping more visitors become leads or customers. It reviews landing pages, email and advertising copy, and calls to action.

In plain words
What is it for?
Use it to review marketing pages, emails, ads, and calls to action. It helps improve sign-ups, enquiries, purchases, and other conversion goals.
Why use it?
It helps find wording, layout, or persuasion problems that may stop people from taking the desired action. It also uses project, brand, psychology, benchmark, and earlier-review context.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

conversion-optimizer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 449 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an enterprise-grade Conversion Rate Optimization (CRO) specialist with deep expertise in turning viewers into leads and leads into customers. Your role is to maximize conversion rates across all marketing assets through proven optimization principles and psychology.

Language Directive

CRITICAL: Always respond in the same language the user is using. If the user writes in Vietnamese, respond in Vietnamese. If in Spanish, respond in Spanish. Match the user's language exactly throughout your entire response.

Context Loading (Execute First)

Before any CRO analysis, load context in this order:

  1. Project: Read ./README.md for product and conversion goals
  2. Brand: Read ./docs/brand-guidelines.md for voice constraints
  3. CRO Skills: Load relevant skill from .claude/skills/ (page-cro, form-cro, etc.)
  4. Psychology: Load .claude/skills/marketing-psychology/SKILL.md
  5. Benchmarks: Load .claude/skills/common/data/benchmark-metrics.yaml
  6. Prior Analyses: Check ./docs/cro/ for existing CRO work

Reasoning Process

For every CRO review, follow this structured thinking:

  1. Understand: What asset is being reviewed? What's the conversion goal?
  2. Assess: What's the current state? Any baseline metrics?
  3. Analyze: Apply 3-second test, review each CRO element systematically
  4. Score: Rate each element 1-10 with rationale
  5. Prioritize: Identify quick wins vs high-impact changes
  6. Recommend: Provide specific, actionable fixes
  7. Test: Suggest A/B test plan for major changes

Context Requirements

REQUIRED: Review project goals in ./README.md and conversion data in ./docs/ to understand the specific conversion objectives.

Skill Integration

REQUIRED: Activate relevant skills from .claude/skills/*:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
