In plain words
What is it for?
Use it to audit or compare App Store and Google Play listings, improve their metadata and visuals, and address ranking or download-conversion problems.

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

aso 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 10d 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.

Origin

This is a copy

89% identical to aso — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

ASO Audit

Analyze App Store and Google Play listings against ASO best practices. Fetches live listing data, scores metadata, visuals, and ratings, then produces a prioritized action plan.

When to Use

  • User shares an App Store or Google Play URL
  • User asks to audit or optimize an app listing
  • User wants to compare their app against competitors
  • User asks about app store ranking, visibility, or download conversion

Before Auditing

Check for product marketing context first: If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Phase 1 — Identify Store & Fetch

Detect store type from URL

Apple:  apps.apple.com/{country}/app/{name}/id{digits}
Google: play.google.com/store/apps/details?id={package}

If the user gives an app name instead of a URL, search the web for: site:apps.apple.com "{app name}" or site:play.google.com "{app name}"

Fetch the listing

Use WebFetch to retrieve the listing page. Extract every available field:

Apple App Store fields:

  • App name (title) — 30 char limit
  • Subtitle — 30 char limit
  • Description (long) — not indexed for search, but matters for conversion
  • Promotional text — 170 chars, updatable without new release
  • Category (primary + secondary)
  • Screenshots (count, order, caption text)
  • Preview video (presence, duration)
  • Rating (average + count)
  • Recent reviews (visible ones)
  • Price / in-app purchases
  • Developer name
  • Last updated date
  • Version history notes
  • Age rating
  • Size
  • Languages / localizations listed
  • In-app events (if any visible)

Google Play fields:

  • App name (title) — 30 char limit
  • Short description — 80 char limit
  • Full description — 4,000 char limit, IS indexed for search
  • Category + tags
  • Feature graphic (presence)
  • Screenshots (count, order)
  • Preview video (presence)
  • Rating (average + count)
  • Recent reviews (visible ones)
  • Price / in-app purchases
  • Developer name
  • Last updated date
  • What's new text
  • Downloads range
  • Content rating
  • Data safety section
  • Languages listed

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.
