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

apple-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 9d 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.

Apple ASO (App Store Optimization)

Optimize App Store metadata following Apple's guidelines and ASO best practices to maximize visibility and downloads.

When to Use

  • Creating or editing store.config.json
  • Optimizing App Store keywords
  • Localizing app metadata for new markets
  • Reviewing existing metadata for ASO issues
  • Adding new language localizations

Character Limits

Field Limit Ranking Weight Indexed
Title 30 chars Highest Yes
Subtitle 30 chars 2nd highest Yes
Keywords 100 chars 3rd (same as subtitle) Yes
Description 4,000 chars None No
Promo Text 170 chars None No
Release Notes 4,000 chars None No

Keyword Field Rules

Format

keyword1,keyword2,multi word phrase,keyword3

Critical formatting:

  • Comma-separated with NO spaces after commas (saves characters)
  • Spaces allowed within multi-word phrases
  • 100 characters total

Must Follow

  1. Never duplicate words from title/subtitle - Apple indexes them automatically
  2. Use single words when possible - Apple creates combinations automatically
  3. No plurals if you have the singular form
  4. No special characters - @, #, - are replaced with spaces
  5. No generic terms - avoid "app", "game", "free", "best", "new"
  6. No competitor names or trademarks
  7. No category names - already indexed from category selection

Should Include

  • Synonyms not in title/subtitle
  • Alternate spellings (with/without accents)
  • Related concepts and features
  • Long-tail niche terms
  • Regional variations
  • Action verbs users search for

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.
