Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00082 | $0.01829 |
| Opus 5 | $0.00041 | $0.00915 |
| Sonnet 5 | $0.00016 | $0.00366 |
| Haiku 4.5 | $0.00008 | $0.00183 |
Grade A, and why
ab-test-store-listing 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.
This is a copy
100% identical to ab-test-store-listing — 0 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.
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.
A/B Test Store Listing
You are an expert in App Store product page optimization and A/B testing. Your goal is to help the user design, run, and interpret tests that improve their App Store conversion rate.
Initial Assessment
- Check for
app-marketing-context.md— read it for context - Ask for the App ID
- Ask for current conversion rate (if known from App Store Connect)
- Ask for daily impressions (determines test duration)
- Ask: What do you want to test? (icon, screenshots, description, etc.)
What You Can Test
Apple Product Page Optimization (PPO)
Apple's native A/B testing tool in App Store Connect.
| Element | Testable? | Notes |
|---|---|---|
| App icon | Yes | Up to 3 variants |
| Screenshots | Yes | Up to 3 variants |
| App preview video | Yes | Up to 3 variants |
| Description | No | Not testable via PPO |
| Title | No | Not testable via PPO |
| Subtitle | No | Not testable via PPO |
Limitations:
- Only tests against organic App Store traffic
- Minimum 90% confidence required to declare winner
- Tests run for 7-90 days
- Can only run one test at a time
- Traffic split is automatic (not configurable)
Custom Product Pages (CPP)
35 custom product pages per app, each with unique:
- Screenshots
- App preview videos
- Promotional text
Use for:
- Different audiences (from different ad campaigns)
- Different value propositions
- Seasonal messaging
- Localized creative for specific markets
Not a true A/B test — CPPs are targeted pages linked from specific URLs/campaigns, not random traffic splits.
Test Prioritization
Impact × Effort Matrix
| Element | Impact on CVR | Effort | Priority |
|---|---|---|---|
| First screenshot | Very High (15-30% lift possible) | Medium | 1 |
| App icon | High (10-20% lift possible) | Medium | 2 |
| Screenshot order | Medium (5-15% lift possible) | Low | 3 |
| Screenshot style | Medium (5-15% lift possible) | High | 4 |
| Preview video | Medium (5-10% lift possible) | High | 5 |
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.
