design-cro

design-cro is a skill for Claude Code from ZachArticulateV/designer-pro-and-seo. It costs 114 tokens per session (690 once invoked), scanned A, original, MIT.

A heuristic review of a landing page or sales funnel. Conversion-rate optimization means improving a page so more visitors complete a goal such as submitting a form, signing up, or buying.

In plain words
What is it for?
Use it to review landing, pricing, checkout, signup, or contact pages. It checks the main call to action, above-the-fold content, form friction, trust placement, clarity, decision load, and mobile use, then prioritizes fixes by impact and effort.
Why use it?
It identifies design and copy choices that may stop visitors from deciding, including competing buttons, heavy forms, weak trust signals, unclear benefits, or too many choices.

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

design-cro 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 12d 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.

Family: design Status: Stable

Purpose

A dedicated CRO skill. Runs a heuristic review of a landing page or funnel against established conversion principles and produces a prioritized list of conversion-killing issues with specific fixes. Works on a URL or local HTML with no external tools; Playwright optionally adds in-browser checks (thumb zones, real interaction).

Reviews against: CTA hierarchy (one primary), above-fold weight, form friction, trust signals near the decision, copy clarity (benefit-led, 3-second headline), decision fatigue, and mobile reality.

Triggers

  • "cro" / "conversion review" / "improve conversions"
  • "why isn't this converting"
  • "landing page review" / "funnel review"
  • "checkout friction review"

Inputs

  • Target URL or local build path
  • Conversion goal (lead form / signup / purchase / call)
  • Target audience and page type (landing | pricing | checkout | signup | contact)

Steps

  1. Get the page. Fetch the URL or read the local HTML (this is the free path).
  2. Walk the heuristic checklist, cross-referencing data/ux-rules.csv (the conversion and cta tagged rules): is there exactly one primary CTA? Is the value prop above the fold? How many form fields? Are trust signals near the CTA? Does the headline read in ~3 seconds? Any decision fatigue / competing actions?
  3. Optional in-browser pass. If Playwright is available, check thumb-zone reachability and real interaction; otherwise note that as a manual check.
  4. Score each finding by Impact (high/med/low) and Fix Effort (high/med/low).
  5. Render the findings ordered by Impact ÷ Effort, each with a specific fix. For copy fixes, hand to copywriting.

Outputs

  • CRO report: prioritized fix list, each tagged Impact + Effort, ordered by leverage
  • Specific, actionable recommendation per finding

Dependencies

  • None required (heuristic review of provided HTML/URL); data/ux-rules.csv for the conversion/CTA rule set
  • Playwright (optional — adds in-browser thumb-zone/interaction checks; free path: manual thumb-zone inspection of the fetched HTML, noted in the report)
  • copywriting (optional — drafts copy fixes; free path: inline copy recommendation per finding)
