What it does
Store Listing Assets is an agent skill from evanca/flutter-ai-rules. Use when writing store copy to character limits (name, subtitle, descriptions, keywords) or preparing listing images (icon, feature graphic, screenshots, preview video).
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/mobile_listing_checklist.md` and `references/spec_reference.md`).
It sits in Media & Creative, covering Transcription. The repository describes itself as: Flutter AI Skills and Rules for Claude, Codex, Cursor, and Other AI-Powered IDEs. The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 7b9cce2. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Store Listing Assets loads about 1.4k tokens when it runs, and up to ~4.7k if it reads all its reference files. Until then it costs about 48 tokens; SKILL.md has 725 words of instructions outside code blocks.
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); files beside SKILL.md are not scanned.

Store Listing Assets & Copy
Prepare the metadata, copy, and visual assets that go into an App Store / Google Play phone listing, sized and length-fit to each store's exact requirements. This is the listing production skill; pair it with a separate review-readiness audit at submission time so the fields are polished and the app itself is ready for review.
Two references hold the authoritative specs; consult them for exact numbers rather than reciting from memory (they drift):
references/mobile_listing_checklist.md— the actionable checklist (shared prep → per-store required → recommended → final check)references/spec_reference.md— the full spec tables, minimal valid examples, store-specific traps, and known gaps to verify live
Default scope is phone-only. Skip tablet, iPad, desktop, Chromebook, TV, watch, Mac, and visionOS assets unless the user says the app supports them — and if they do, note that those are separate asset families outside these specs.
How to use this skill
- Gather the inputs once (shared prep): final app name, what the app does in one sentence, primary category, whether it has ads, whether it collects/shares/tracks data, privacy policy URL, support contact, and launch languages. These feed both stores.
- Confirm which store(s) the user is targeting — the required set differs enough that doing both blindly wastes effort.
- Produce copy AND/OR assets per the requests below, always checking generated text against the live character/byte limits and generated images against the exact pixel/format specs.
Writing store copy (fit to limits)
Character limits are hard constraints — always count and show the count. Key limits (full set in the references):
| Field | Google Play | Apple |
|---|---|---|
| App name | 30 chars | 2–30 chars |
| Subtitle | — (no field) | 30 chars |
| Short description | 80 chars | — (use Promotional Text, 170) |
| Full description | 4,000 chars | 4,000 chars, plain text |
| Keywords | — (no field; don't keyword-stuff the description) | ≤100 bytes, each keyword >2 chars |
Copywriting rules that keep the listing compliant:
- Lead with what the app does, in the first sentence — it's what shows before "more".
- Apple keywords are bytes, not characters, comma-separated with no spaces (
notes,checklists,tasks) to save bytes; non-ASCII eats more than one byte each. Keywords are invisible to users but drive search — don't repeat the app name or category (already indexed). - Avoid claim words: "best", "#1", "free" (unless unconditionally true), rankings, awards, and pricing claims — in text AND baked into images. These trigger rejection and are called out in both stores' policies.
- When both stores are in play, write once and adapt: Play's 80-char short description ≈ Apple's subtitle+promo-text job; Apple needs a keywords line Play doesn't.
- Offer to localize per launch language; note Apple defaults screenshots/shared metadata from the primary language when you add a localization, except description and keywords (write those per language).

Producing visual assets (exact specs)
When generating or resizing images with tooling (ImageMagick, etc.), hit these exactly — wrong format/alpha/dimension is an instant listing error:
Google Play
- Play icon: 512×512 px, 32-bit PNG with alpha, ≤1024 KB
- Feature graphic: 1024×500 px, JPEG or 24-bit PNG, no alpha — required to publish
- Phone screenshots: 2–8, JPEG or 24-bit PNG, no alpha, min side 320 px, max 3840 px, longest side ≤ 2× shortest. Recommended: ≥4 at 1080×1920 (portrait) or 1920×1080 (landscape)
Apple (iPhone)
- Icon: comes from the build (Xcode asset catalog, one 1024×1024 source) — not a separate listing upload
- iPhone screenshots: 1–10, .jpg/.jpeg/.png. Preferred 6.9": 1320×2868, 1290×2796, or 1260×2736 portrait; if not providing 6.9", 6.5" required: 1284×2778 or 1242×2688. Apple scales down to smaller iPhones
- App preview (optional): ≤3 per size/language, 15–30 s, ≤500 MB, ≤30 fps, H.264/.mp4 (reusable iPhone res 886×1920 / 1920×886)
Screenshot content rules: show real app UI in use (not splash/login/mockups), no unsupported devices, no fake UI, no misleading or pricing claims baked in. Verify generated images match the actual submitted build.
Deliverables
- Full listing copy set — name, subtitle/short description, full description, keywords, promotional text — each labeled with its character/byte count against the limit, per targeted store
- Asset spec sheet / production — the exact dimensions and formats the user needs, or the generated/resized images themselves (offer to run ImageMagick for resizing/format conversion)
- Fill-in-the-fields walkthrough — the checklist from
references/mobile_listing_checklist.mdadapted to the user's app, marking which conditional items apply (account deletion URL, app access instructions, restricted permissions, export compliance) - Pre-submission asset audit — the section 6 final check: assets match the build, no placeholder/staging content, name consistent everywhere, previewed in each language
At submission time, also run a review-readiness audit, and if RevenueCat/paywalls are involved, verify paywall clarity separately.
