What it does

Store Screenshots is an agent skill from pandulapeter/campfire. Retake Campfire's promotional images for every platform and form factor — the store listings (Play Store, App Store, Mac App Store, Microsoft Store), the Play Store feature graphic, Apple's product page header and search results images, the README banners and campfire-songbook.com's screenshots and link preview. Renders them with the offscreen screenshot tool in tools/screenshots, checks them, frames them in the Screenshot Bro project and exports the store images to a new folder on the Desktop, the README banners…

Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `scripts/readme_banners.py` and `scripts/website_screenshots.py`).

It sits in Mobile, covering App store release and Technical documentation. It works with macOS. The repository describes itself as: A cross-platform songbook and metronome with a built-in chordPro editor, setlists, transposition, PDF export, and Dropbox sync. The licence is MPL-2.0.

When your agent uses it

  • Update the store screenshots / store images / listing screenshots / README
  • Website screenshots
  • Reorder one of them

Example prompts

  • “/store-screenshots”

Requirements

  • Python 3

Workflow steps

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

  1. Render. ./gradlew :tools:screenshots:run (in the background; one app start per image, a few seconds each)
  2. Check every image before importing anything: a contact sheet per shot (PIL), then any device that looks off at
  3. Stage. Screenshot Bro is sandboxed and reads only its own container: copy renders/ into
  4. Import. Take get_project first: the user arranges the rows by hand between runs, and **their layout is kept
  5. Look at every row with render_preview, a column at full size where anything is in doubt: the status bar's
  6. Export with export_project (into the app's temp folder; a non-empty unrenderable means holes — report it).
  7. The website: `python3 -I .claude/skills/store-screenshots/scripts/website_screenshots.py
  8. Clean up the staging and export folders in the app's container, and report the Desktop folder, what was

What it can do on your machine

Read from SKILL.md and the folder at commit 94d4b7f. 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 2 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

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

  • Network

    Links to these hosts (documentation or services it may open):

    • mozilla.org

    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

Store Screenshots loads about 3k tokens when it runs. Until then it costs about 244 tokens; SKILL.md has 1,555 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~244
When it runs · the whole SKILL.md, loaded when a task matches
~3k

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
Retake Campfire's promotional images for every platform and form factor — the store listings (Play Store, App Store, Mac App Store, Microsoft Store), the Play Store feature graphic, Apple's product page header and search results images, the README banners and campfire-songbook.com's screenshots and link preview. Renders them with the offscreen screenshot tool in tools/screenshots, checks them, frames them in the Screenshot Bro project and exports the store images to a new folder on the Desktop, the README banners to documentation/screenshots and the website's images to the sibling CampfireWebsite repository. Invoke this skill WHENEVER the user asks to retake, regenerate, refresh or update the store screenshots / store images / listing screenshots / README or website screenshots, or to add, change or reorder one of them. Not for screenshots taken to verify a change while developing (that is the run skill and the platform verification recipes).

Campfire promotional images

Every image is made from the desktop build drawn offscreen as each platform (the platforms share every line of the interface), with that platform's fonts, scale and system bars, at the exact pixels of the Screenshot Bro device frame it goes into. Nothing here touches the production apps: the tool is tools/screenshots, which no app module depends on, and the only seam in the app is PlatformImpersonation in :presentation's desktop source set, which the desktop app never sets. See tools/screenshots/CLAUDE.md for how the tool works.

What a run needs

  • The library, in tools/screenshots/library/ (gitignored, never committed): a Campfire data folder's library/, covers/ and preferences/preferences.json, copied from the user's desktop library without the sync credentials, the sync index or the log. If it is missing, stop and ask. Never write into the user's real data folder. Its setlists were trimmed for the shots (Frey-Tully Nuptials and Getting started); keep them that way.
  • Screenshot Bro running, with the Campfire project (list_projects), and Full Disk Access for the IDE that runs Claude Code (Android Studio), without which nothing can be staged in the app's sandbox (step 3).
  • The display does not matter: nothing is drawn on screen.

Where everything goes

WhatMade fromEnds up in
Store listings (8 rows × 8 shots), Play Store banner, link preview, Apple header and search resultsShot.kt, Banners.kt → Screenshot Bro~/Desktop/Campfire store images <date>/, one folder per row (with the project's icon, poster and box art rows, which have no shots)
README banners (GitHub - Banner 1 / 2)Banners.kt → Screenshot Brodocumentation/screenshots/01–06.webp, 1200×900
Website screenshotsWebsite.kt, no Screenshot Bro../CampfireWebsite/assets/screenshots/*.webp at each file's own size
Website link previewthe exported Website - Link preview row../CampfireWebsite/assets/og-image.jpg, 1200×630

Raw renders go to the gitignored tools/screenshots/renders/, replaced on every run. Nothing is committed, in either repository; the user reviews and commits.

Steps

  1. Render. ./gradlew :tools:screenshots:run (in the background; one app start per image, a few seconds each) writes every shot of Shot.kt on every listing Device, the multi-device rows of Banners.kt and the website set of Website.kt into tools/screenshots/renders/<row label>/. --args="--only IPHONE,03-metronome,banners" renders part of it (device enum names, shot ids, or listing, banners, website). A failed render is reported and the run goes on. Never rebuild the tool while a render is running.

  2. Check every image before importing anything: a contact sheet per shot (PIL), then any device that looks off at full size — the theme, nothing loading, no stray dialog or snackbar, the shot's rules (below), text fitting. Fix the shot or the tool and render again rather than importing a bad image.

  3. Stage. Screenshot Bro is sandboxed and reads only its own container: copy renders/ into ~/Library/Containers/xyz.tleskiv.screenshot/Data/tmp/campfire/. The large Android tablet's frames are rotated 270°, so its images are staged rotated a quarter turn clockwise (PIL ROTATE_270).

  4. Import. Take get_project first: the user arranges the rows by hand between runs, and their layout is kept exactly — positions, sizes, tilts, stacking. import_screenshots fills a row's device frames one per column, in column order, the rearmost frame of each column, and resizes every frame it fills to the image's aspect ratio, so after every import put each frame's x, width and height back. Extra images append columns: never pass more than the row has.

    • The eight listing rows (one frame per column): import the row's eight images in order.
    • Rows with several frames in a column (the README banners, the Play Store banner, the link preview, Apple's header and search results): give each extra frame a temporary column (add_template, delete_shape the default device it drops in, move the frame's x there), import, move it back, remove_template. Then restore the stacking with z_order: front in back-to-front order, keeping every MacBook's black camera-housing strip above its frame.

    If a row's label or column count is not what this table and the code expect, stop and say so. Headlines are the project's text shapes, never part of the images.

  5. Look at every row with render_preview, a column at full size where anything is in doubt: the status bar's time and the navigation labels uncut, the image filling its frame, nothing upside down or stretched.

  6. Export with export_project (into the app's temp folder; a non-empty unrenderable means holes — report it). Copy every row's folder except the two GitHub banners to a new ~/Desktop/Campfire store images <date>/. The banners go to the README: python3 -I .claude/skills/store-screenshots/scripts/readme_banners.py <repo root> followed by banner 1's three exported images and then banner 2's.

  7. The website: python3 -I .claude/skills/store-screenshots/scripts/website_screenshots.py tools/screenshots/renders/Website "<Desktop folder>/Website - Link preview — 1200x630/01_Website - Link preview_en.png" "$HOME/Desktop/Campfire website images" writes every website screenshot at the size of the file it replaces, as WebP, and the link preview as og-image.jpg; where the sibling CampfireWebsite repository is missing it writes them to the Desktop folder instead.

  8. Clean up the staging and export folders in the app's container, and report the Desktop folder, what was rendered and anything that looked off.

The shots and their rules

The listing alternates two dark, two light: 1–2 dark, 3–4 light, 5–6 dark, 7–8 light. Shared rules: the store screenshots are shown at 9:41 on Wednesday, October 7, 2026 (setlist dates are moved with the run's day, so their countdowns always read the same); the app icon anywhere in the system chrome is the default gradient one; Android phone frames are Screenshot Bro's Pixel frame; Share is shown on Android and iOS only; sync is a fake connected account, "Connected as Péter Pandula"; only public domain songs are opened full screen in the listing.

The README banners are shots 1, 3, 2, 4, 5 on the Android phone, iPhone, iPad, small Android tablet and Mac — dark in banner 1, light and in reverse order in banner 2. The Play Store banner is the Android phone's shots 1 and 2; the link preview the Mac's 2 and the iPhone's 1; Apple's header the iPad's 4, the Mac's 2 and the iPhone's 1, and its search results image the iPad's 2 and the iPhone's 3, all dark.

The website's songs are set at the text size where page one ends exactly where a section ends, never inside one: Still Alive 90% (Verse 2 in one column), Accidentally in Love 90% with the metronome panel open, I'll Be There for You 105% on the laptop. A song longer than a page is cut wherever a column ends, so these were found by rendering every size from 80% to 130% in steps of 2.5% and reading where page one ends; if a song, a device or the layout changes, try again the same way. Never fold the Chords section (or anything else) to make a song fit. The laptop is a Mac window with no system chrome at 1.5× (Device.LAPTOP).

Changing a shot

The listing is shots in Shot.kt, in store order; the website's are in Website.kt and the multi-device rows in Banners.kt. A shot sets the preferences it needs (preferences, per device), prepares state a screen only reads as it is first composed (prepare, e.g. a list's scroll position), then drives CampfireViewModel or taps what is labelled with a string resource (drive, tap, tapIfPresent) — so it works in every language — and can catch a metronome beat (beat). Keep each shot's rules in its comment and in the table above. Adding or removing a listing shot also means adding or removing that column in every listing row of the project (copying a neighbor's frame and headline), and updating the headlines there.

The system chrome is SystemChrome.kt, measured against the real systems (Android emulators, iOS simulators, the desktop app's own window). The Chromebook and Windows rows are framed in MacBook Pros whose camera housing a black rectangle of the project hides; their shots start the window under a black band of that rectangle's height (36 and 38 dp), so if those rectangles or frames are moved or resized, measure again and update the band heights.
