ASO & App Marketing Skills is a collection of AI-agent skills for improving mobile-app discoverability and marketing through keyword research, metadata optimization, competitor analysis, and market data. It is for indie developers, app marketers, and growth teams using compatible coding agents, and the catalogue contains the skills and instructions they use.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 118 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00124 | $0.01613 |
| Opus 5 | $0.00062 | $0.00807 |
| Sonnet 5 | $0.00025 | $0.00323 |
| Haiku 4.5 | $0.00012 | $0.00161 |
Grade A, and why
crash-analytics 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.
How it starts
The opening of the file, as written. The whole thing — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Crash Analytics
You help triage, prioritize, and reduce app crashes — and understand how crash rate affects App Store discoverability and ratings.
Why Crash Rate Is an ASO Signal
- App Store ranking — Apple's algorithm penalizes apps with high crash rates
- App Store featuring — High crash rate disqualifies editorial consideration
- Ratings — Crashes are the #1 cause of 1-star reviews
- Retention — A crash in the first session destroys Day 1 retention
Target: crash-free sessions > 99.5% | crash-free users > 99%
Tools
| Tool | What it provides | Setup |
|---|---|---|
| Firebase Crashlytics | Real-time crashes, ANRs, symbolicated stack traces | Add FirebaseCrashlytics pod/SPM package |
| App Store Connect | Crash rate trend, crashes per session | Built-in, no code needed |
| Xcode Organizer | Aggregated crash logs from TestFlight + App Store | Xcode → Window → Organizer → Crashes |
| MetricKit | On-device diagnostics, hang rate, launch time | iOS 13+, automatic |
Recommended: Crashlytics (real-time alerts + search) + App Store Connect (trend validation)
Crashlytics Setup
iOS (Swift)
// AppDelegate or @main App struct
import FirebaseCore
import FirebaseCrashlytics
@main
struct MyApp: App {
init() {
FirebaseApp.configure()
// Crashlytics is auto-initialized
}
}
Non-fatal errors (track without crashing)
// Log a non-fatal error
Crashlytics.crashlytics().record(error: error)
// Log a custom key for debugging context
Crashlytics.crashlytics().setCustomValue(userId, forKey: "user_id")
Crashlytics.crashlytics().setCustomValue(screenName, forKey: "current_screen")
Android (Kotlin)
// build.gradle (app)
implementation("com.google.firebase:firebase-crashlytics:18.x.x")
// No additional code needed — auto-captures unhandled exceptions
// For non-fatal:
FirebaseCrashlytics.getInstance().recordException(throwable)
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.

crash-analytics is a skill published in the GitHub repository Eronred/aso-skills (1,843 stars, last pushed 18d ago), licensed MIT. It adds 124 tokens to every session and 1,613 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

asc-crash-triage
Triage TestFlight crashes, beta feedback, and performance diagnostics using asc. Use when the user asks about TF crashes, TestFlight crash reports, beta tester feedback, app hangs, disk writes, launch diagnostics, or wants a crash summary for a build or app.
de-vibe
Audit and fix the tells that software was vibe-coded / AI-generated, then give it a small distinctive identity, so it ships looking handcrafted and professional.
