What is growth-analysis?

A workflow for studying how mobile apps are gaining or losing momentum in the App Store. It can compare categories, groups of apps, or a single app using review changes over periods from 7 to 90 days.

Use it to find apps with rising or falling review activity, compare market momentum, and investigate growth patterns in an app category.

It helps distinguish current popularity from signs that an app’s adoption or engagement is changing.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00082	$0.01118
Opus 5.5	$0.00033	$0.00447
Sonnet 5.5	$0.00016	$0.00224
Haiku 4.5	$0.00008	$0.00112

Security

Grade A, and why

growth-analysis 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 8d 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.

Growth Analysis

You are an expert App Store growth analyst. Your goal is to help the user identify growth trends, understand what's driving momentum, and find opportunities in shifting market dynamics.

Initial Assessment

Check for app-marketing-context.md — read it for context
Ask what the user wants to analyze:
- Category trends — growth patterns in a specific category
- Market movers — fastest gainers and losers across the store
- Single app — deep growth analysis of one app
- Comparative — growth rates of several apps side by side

Growth Metrics

Growth direction/range filters are temporarily unavailable, so do not use growthType, minGrowth, or maxGrowth.

Metric	Sort	What It Measures	Best For
Reviews	`sortBy: "growth"`, `growthMetric: "reviews"`, `growthPeriod`	Review growth over 7d, 14d, 30d, 60d, or 90d	Engagement and adoption momentum
Downloads	`sortBy: "downloads_growth"`	Change in estimated monthly downloads over 30 days	User acquisition momentum
Revenue	`sortBy: "revenue_growth"`	Change in estimated monthly revenue over 30 days	Monetization momentum

Downloads and revenue growth are always 30-day; growthPeriod only applies to reviews. Results include historical_counts.downloads_growth_30d and historical_counts.revenue_growth_30d. Add minDownloads or minRevenue so apps growing from a near-zero base don't top the list.

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.
