What it does

Genie의 프레임워크 중립 Android·iOS 출시 스킬. 사용자가 "지니, 모바일 출시 준비해줘", "Flutter 앱을 TestFlight와 Play 내부 테스트에 올려줘", "React Native 앱 버전과 서명을 점검해줘", "스토어 단계적 출시를 추적해줘"라고 요청할 때 사용한다. 프로젝트에 설정된 빌드·서명·테스트 트랙·스토어 절차를 실행하고 버전과 릴리스 식별자를 기록한다.

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

121. .genie/config.json, .genie/deploy.json, 프로젝트 배포 문서와 최신 genie-ship, genie-mobile-qa-only 기록을 확인하라.
132. Flutter이면 ../../references/flutter-mobile.md, React Native 또는 Expo이면 ../../references/react-native-mobile.md를 읽고 Android·iOS 대상, Expo·OTA와 네이티브 빌드 여부를 확인하라.
143. 앱 버전, Android versionCode, iOS build number, 환경·flavor와 source commit을 고정하라.
154. 서명 파일이나 인증 값을 문서에 저장하지 말고 Secret 참조와 인증 상태만 확인하라.

191. 설정된 정적 분석, 테스트와 릴리스 빌드를 실행하라.
202. 산출물의 앱 ID, 환경, 버전, 서명과 포함된 source commit을 확인하라.
213. 내부 테스트 → 제한 테스트 → 단계적 운영 출시 순서를 프로젝트 설정대로 적용하라.
224. OTA가 있으면 네이티브 바이너리 호환 범위와 OTA 릴리스를 별도 식별자로 기록하라.
235. 스토어 제출 결과, 빌드 ID, 트랙, 심사 상태와 롤아웃 비율을 수집하고 후속 genie-mobile-canary를 권장하라.

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈70
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
480
on trigger
The instruction body and 1 supporting file, read only when the skill fires.
0.27%
of a 200k window
Ten skills this size would take about 3% of the window before you open a file.
050k100k150k200k context window

550 tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Small enough to keep loaded permanently without thinking about it.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

2 files, 2.2 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md2.0 kB
  • agents/openai.yaml0.2 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 2 files you can review in full before installing. The MIT licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Mobile App Release Manager · 550 tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/purplerinn-mobile-app-release-manager/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/mobile-app-release-manager" ] && { [ ! -e .claude/skills/mobile-app-release-manager ] || { mv .claude/skills/mobile-app-release-manager "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/mobile-app-release-manager" .claude/skills/ && echo "Installed .claude/skills/mobile-app-release-manager"
On Windows, or any OS with Node 20+
npx mcprush@latest skill add purplerinn/mobile-app-release-manager

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/mobile-app-release-manager/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/purplerinn-mobile-app-release-manager/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/mobile-app-release-manager" ] && { [ ! -e ~/.claude/skills/mobile-app-release-manager ] || { mv ~/.claude/skills/mobile-app-release-manager "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/mobile-app-release-manager" ~/.claude/skills/ && echo "Installed ~/.claude/skills/mobile-app-release-manager" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/mobile-app-release-manager/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where. It appears as genie-mobile-release in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, mobile-app-release-manager.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
