asc-aso-audit

asc-aso-audit is a skill for Claude Code from hanamizuki/solopreneur. It costs 40 tokens per session (2,427 once invoked), scanned A, a copy of asc-aso-audit, MIT.

An offline audit of App Store metadata, with optional keyword-gap analysis through Astro MCP. App Store metadata is the title, description, keywords, and related information used to present and help people find an app.

In plain words
What is it for?
Use it after downloading metadata to check the latest version and primary language, review keyword gaps, and include Apple-generated discoverability tags when available.
Why use it?
It finds metadata rule problems and possible missing search terms before you publish an app version. The local checks work without the optional Astro connection.

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

asc-aso-audit 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 20d 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 — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.

asc ASO audit

Run a two-phase ASO audit: offline checks against local metadata files, then keyword gap analysis via Astro MCP. When available, include Apple-generated app tags as a discoverability signal.

Preconditions

  • Metadata pulled locally into canonical files via asc metadata pull --app "APP_ID" --version "1.2.3" --dir "./metadata".
  • If metadata came from asc migrate export or asc localizations download, normalize it into the canonical ./metadata layout before running this skill.
  • For Astro gap analysis: app tracked in Astro MCP (optional — offline checks run without it).
  • For Apple-generated discoverability tags: asc app-tags list --app "APP_ID" --output json works when the API returns tags for the app.

Before You Start

  1. Read references/aso_rules.md to understand the rules each check enforces.
  2. Identify the latest version directory under metadata/version/ (highest semantic version number). Use this for all version-level fields.
  3. The primary locale is en-US unless the user specifies otherwise.

Metadata File Paths

  • App-info fields (subtitle): metadata/app-info/{locale}.json
  • Version fields (keywords, description, whatsNew): metadata/version/{latest-version}/{locale}.json
  • App name: May not be present in exported metadata. If name is missing from the app-info JSON, fetch it via asc apps info list or ask the user. Do not flag it as a missing-field error.

Phase 1: Offline Checks

Run these 5 checks against the local metadata directory. No network calls required.

1. Keyword Waste

Tokenize the subtitle field (and name if available). Flag any token that also appears in the keywords field — it is already indexed and wastes keyword budget.

Severity: ⚠️ Warning
Example:  "quran" appears in subtitle AND keywords — remove from keywords to free 6 characters

How to check:

  1. Read metadata/app-info/{locale}.json for subtitle (and name if present)
  2. Read metadata/version/{latest-version}/{locale}.json for keywords
  3. Tokenize subtitle (+ name):
    • Latin/Cyrillic scripts: split by whitespace, strip leading/trailing punctuation, lowercase
    • Chinese/Japanese/Korean: split by 、 , , or iterate characters — each character or character-group is a token. Whitespace tokenization does not work for CJK.
    • Arabic: split by whitespace, then also generate prefix-stripped variants (remove ال prefix) since Apple likely normalizes definite articles. For example, "القرآن" in subtitle should flag both "القرآن" and "قرآن" in keywords.
  4. Split keywords by comma, trim whitespace, lowercase
  5. Report intersection (including fuzzy matches from prefix stripping)

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.
