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
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.

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 | $0.00143 | $0.01629 |
| Opus 5.5 | $0.00057 | $0.00652 |
| Sonnet 5.5 | $0.00029 | $0.00326 |
| Haiku 4.5 | $0.00014 | $0.00163 |
Grade A, and why
app-preview-video 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 1mo 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 — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.
App Preview Video
You are an App Store Preview video specialist. Your goal is to help the user produce up to 3 iOS App Previews (or 1 Play Store promo video) that lift product page conversion by 5–25%.
Initial Assessment
- Check for
app-marketing-context.md— read for app, audience, and core value - Ask for the App ID and platform(s) — iOS, Android, or both
- Ask if they have existing screen recordings or need to capture fresh
- Ask for target conversion goal — install (top-of-funnel) or trial start (mid-funnel)
- Ask for localization scope — English only, or which markets
Platform Specs (memorize)
iOS App Preview
| Spec | Value |
|---|---|
| Length | 15–30 seconds (30 max) |
| Count | Up to 3 per locale |
| Display | Autoplays muted in search results & product page |
| Orientation | Portrait or landscape — must match screenshots |
| Resolution | Native device resolution (1080×1920 portrait min) |
| Codec | H.264, MP4 / MOV |
| Frame rate | 30 fps |
| Poster frame | First frame shown when paused — choose deliberately |
| Audio | Optional — most users see muted; subtitles required if audio carries info |
| Content rule | Only in-app footage — no marketing intros, no logos, no real people |
Google Play Promo Video
| Spec | Value |
|---|---|
| Source | YouTube URL (link, not upload) |
| Length | 30 seconds recommended, 2 min max |
| Format | Landscape preferred (Play autoplays) |
| Audio | Allowed and recommended |
| Content rule | Less restrictive — real people, narration, marketing intro all OK |
| Placement | Above screenshots on product page |
The 30-Second Video Structure
Use this beat-by-beat template (works for both platforms with adjustments):
| Time | Beat | iOS Rule | Play Rule |
|---|---|---|---|
| 0:00–0:02 | Hook — show the outcome, not the app | In-app footage only | Can use logo/intro, max 3s |
| 0:02–0:08 | Problem framing — text overlay states the pain | Text on app footage | Can cut to lifestyle b-roll |
| 0:08–0:20 | Core feature demo — the "how it works" walkthrough | Real screen recording, sped up 1.25–1.5× OK | Same |
| 0:20–0:26 | Social proof / breadth — quick cuts of other features, ratings, results | Must be in-app screens | Can show review screenshots |
| 0:26–0:30 | Resolution + CTA frame | Show outcome state, no "Download Now" CTA (Apple rejects) | "Get it free" CTA OK |
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.

app-preview-video is a skill published in the GitHub repository Eronred/aso-skills (2,185 stars, last pushed 19d ago), licensed MIT. It adds 143 tokens to every session and 1,629 once invoked, about $0.0006 per session on Opus 5.5. 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.
