aso makes Claude fetch your App Store or Google Play listing, score it on six areas and write a prioritized action plan. The areas are title and subtitle, description, visual assets, ratings and reviews, metadata and freshness, and conversion signals.

It triggers when you share a store URL or ask to optimize an app listing. It uses web fetching and a page screenshot to read the listing, and it can compare competitors. The folder bundles five reference files and an evals file, and no scripts.

Good for

App founders and indie developers whose app is not getting downloads
Marketers who run app store optimization for a client
Product teams comparing their listing against 2 or 3 competitors

What it includes

Reads the listing page and takes a screenshot
Detects Apple or Google from the URL, fetches the page and captures a screenshot for icon and screenshot quality. Given an app name, it searches the web. Listing text is treated as untrusted.
Network · Phase 1: Identify store and fetch
Classes the app as Dominant, Established or Challenger
The tier changes how strictly it scores. A household-name app gets benefit of the doubt on brand-first titles.
Phase 1.5: Assess brand maturity
Weights add up to 100
Title and subtitle 20%, description 15%, visual assets 25%, ratings and reviews 20%, metadata and freshness 10%, conversion signals 10%.
Phase 2: Score six dimensions
Optional: scores 2 or 3 competitors the same way
Builds a comparison table and finds keyword gaps. If you give no competitors it offers to search for them.
Network · Phase 3: Competitor comparison
Fixed report layout
Score card, top 3 quick wins, detailed findings, keyword suggestions, visual asset recommendations and a priority plan. Every recommendation is specific, with character counts.
Phase 4: Generate report
Flags frequent listing problems
Examples: rating below 4.0, last update over 3 months ago and fewer than 5 screenshots.
Common issues checklist

Questions

How do I install aso?

Use the install box above. The repo README also documents the full marketing-skills plugin for Claude Code and Codex, and a one-skill ZIP for the Claude web app on the repo's Releases page.

Do I need the product-marketing skill first?

No. The SKILL.md only says to read a product marketing context file if one exists (.agents/product-marketing.md, .claude/product-marketing.md or the older product-marketing-context.md) and to ask you for anything it does not cover. The README calls product-marketing the foundation the other skills check first.

What do I give aso?

An App Store or Google Play URL, or the app name. It also asks whether the app is yours or a competitor's, its category, any competitor URLs and whether you care more about search visibility or conversion.

Does aso need paid ASO tools?

The SKILL.md names no paid tool or API key. It says to note what cannot be assessed without paid tools, such as search volume and exact rankings.

Does aso work in the Claude app or Codex?

The README documents a Codex plugin and a one-skill ZIP for the Claude web app, uploaded under Customize, then Skills. Claude Code is covered by the skills CLI and the plugin.

Is aso safe?

It makes Claude fetch store pages and may take a screenshot with browser tools. The skill tells Claude to treat listing text and reviews as untrusted data and not follow instructions inside them. It bundles no scripts.

How is it different from the cro skill?

The SKILL.md points to cro for the web landing pages that drive app installs. aso is only for store listings.
