What it does

App Store Screenshots is an agent skill from gug007/lpm. Make the App Store screenshots for lpm Link (iPhone 6.3" 1206x2622 and iPad 13" 2064x2752) from the current mobile/ source: a screenshot build of the app opens each screen straight into Demo Mode sample data in the iOS Simulator (no taps, no personal data), and each capture is laid into a store image with a headline, a subline and a device frame. Captions, order and screens live in shots.json. Use when the user asks for new, updated or regenerated App Store / App Store Connect screenshots, store images, or…

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including scripts (for example `scripts/build.js`, `scripts/compose.js` and `scripts/paths.js`).

It sits in Mobile, covering App store release and iOS development. It works with iOS and App Store Connect. The repository describes itself as: Start, stop, and duplicate dev projects with one click. The best workspace for running Claude Code, Codex, and other AI agents alongside your services. The licence is MIT.

When your agent uses it

  • The user asks for new
  • Regenerated App Store / App Store Connect screenshots
  • Product page screenshots for the iOS app

Example prompts

  • “1206x2622 and iPad 13”
  • “/app-store-screenshots”

Requirements

  • Node.js

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Read both contact sheets and one image per device at full size: every screen is the one its
  2. Give the user the full paths (ls the folders).
  3. Uploading to App Store Connect replaces public listing images: only with the user's OK.

What it can do on your machine

Read from SKILL.md and the folder at commit 57f7a3f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 8 files in scripts/ (JavaScript and Swift), which the agent can run.

    Shell commands in SKILL.md call:

    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

App Store Screenshots loads about 1.2k tokens when it runs. Until then it costs about 144 tokens; SKILL.md has 556 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~144
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Make the App Store screenshots for lpm Link (iPhone 6.3" 1206x2622 and iPad 13" 2064x2752) from the current mobile/ source: a screenshot build of the app opens each screen straight into Demo Mode sample data in the iOS Simulator (no taps, no personal data), and each capture is laid into a store image with a headline, a subline and a device frame. Captions, order and screens live in shots.json. Use when the user asks for new, updated or regenerated App Store / App Store Connect screenshots, store images, or product page screenshots for the iOS app.
version
1.0.0
argument-hint
[--device iphone|ipad] [--only name,name]

Makes the lpm Link App Store screenshots again whenever the app changes, with no clicking: scripts/shots.js builds a screenshot copy of the app, launches it once per screen in the iOS Simulator, and composes the store images.

node scripts/shots.js all          # build, prepare, capture, compose (~2.5 min)
node scripts/shots.js capture --only diff,stats --device iphone
node scripts/shots.js compose      # after editing captions only (seconds)
node scripts/shots.js cleanup      # clear status bars, shut down simulators it booted
  • build copies mobile/ to ~/Library/Caches/lpm-app-store-shots/src (the repo is never touched), applies the PATCHES in scripts/build.js, adds scripts/swift/*.swift, runs xcodegen and a Release simulator build. The copy shows Demo Mode as a real Mac: no purple Demo banner, the Mac is "MacBook Pro", the status line reads "Connected · on your network", a busier sample seed (ShotSeed.swift), and the storefront Claude session already finished and waiting on you.
  • prepare finds (or creates) the simulators named in shots.json, sets US English (the clock reads 9:41, not 09:41; reboots once), a full non-charging battery, light mode, and installs the build.
  • capture launches the app with LPM_SHOT_ROUTE=<route> (ShotDriver.swift enters Demo Mode and pushes the route), waits, and saves simctl io screenshot at native size.
  • compose (compose.swift) writes the store images without an alpha channel (App Store Connect rejects one) and a contact sheet per device.

Output: ~/Pictures/lpm-link-app-store/<version>/ with iphone-6.3/NN-name.png, ipad-13/NN-name.png, sheet-iphone.png, sheet-ipad.png and source/raw/. The version comes from mobile/project.yml; --version <v> writes elsewhere (use it to try changes without replacing a set the user already has).

shots.json: devices (simulator name, folder, size) and shots in store order, each with name, route, title (\n for the line break, two lines at most), subtitle (one line, about 50 characters on iPhone), devices, and an optional wait in seconds (default 4). Route steps, joined by >, are pushed in order: list · project:<name> · terminal:<project>/<terminalId> · changes:<project> · usage · stats · activity · automations · automation:<project>/<jobId>. Demo names: projects storefront, api-gateway, analytics, mobile-app, blog, …; terminal demo-storefront-claude; automation nightly-tests (mobile/Sources/LpmMobile/DemoWorld.swift, DemoJobs).

After a run

  1. Read both contact sheets and one image per device at full size: every screen is the one its caption names, no "Demo" wording, nothing personal, text not clipped.
  2. Give the user the full paths (ls the folders).
  3. Uploading to App Store Connect replaces public listing images: only with the user's OK. Version page → App Previews and Screenshots → "iPhone with Dynamic Island (medium display)" and "iPad 13" display" → Remove All, then upload in order. Chrome's file_upload only reads files this session may read: copy the PNGs into the scratchpad first.

When the app changes

  • A screen moved or got a new look: just run all.
  • build stops with "patch anchor … matched 0 times": the patched code changed. Update that entry in PATCHES (scripts/build.js) to the new code; each anchor must match once.
  • A new screen to show: if no route step reaches it, add a case to NotificationRoute and its destination through PATCHES, and the step to ShotDriver.path.
  • New sample data: ShotSeed.swift (screenshot only) or the Demo Mode seed itself.

Traps

  • Store copy never mentions Tailscale (the user's call), and the first "Connect to your Mac" screen promotes it, so it isn't in the set.
  • Xcode 27 has no Simulator.app (it's Device Hub, com.apple.dt.Devices); this skill doesn't need a window at all. Other sessions may run their own simulators: cleanup only touches the ones named in shots.json and only shuts down those it booted.
  • iPadOS runs the app in a window: the iPad status bar shows "lpm" and a resize corner.
  • Usage and Stats figures come from the demo seed relative to now, so they shift a little between runs.
