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 | $0.00047 | $0.00786 |
| Opus 5.5 | $0.00019 | $0.00314 |
| Sonnet 5.5 | $0.00009 | $0.00157 |
| Haiku 4.5 | $0.00005 | $0.00079 |
Grade A, and why
app-store-screenshots 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
App Store & Google Play Screenshots Generator
Build a Next.js application for creating exportable App Store and Google Play marketing screenshots across multiple device types and platforms.
Core Philosophy
"Screenshots are advertisements, not documentation. Every screenshot sells one idea."
Key Capabilities
Supports rendering screenshots for:
- iPhone (portrait with mockup.png frame)
- iPad (portrait, CSS-rendered frame)
- Android Phone (portrait, CSS-rendered)
- Android Tablets (7" and 10", portrait + landscape)
- Google Play Feature Graphic (1024×500 banner)
Core Workflow
Before coding, gather these inputs:
- Screenshot image locations
- App icon PNG path
- Brand colors (accent, text, background)
- Typography selection
- Feature prioritization
- Desired slide count
- Visual style direction
- Target platform(s)
- Language localization needs
- Theme customization preferences
Technical Foundation
Uses html-to-image for export, not html2canvas, due to superior CSS handling.
Critical implementation patterns:
- Pre-load images as base64 data URIs to prevent non-deterministic fetch failures
- Double-call export technique (first warm-up, second production)
- Device-agnostic width formulas that scale proportionally across canvas sizes
- Slide factory pattern for reusable device-specific templates
Canvas Dimensions
Design at largest resolution per category; exports scale down automatically:
| Device | Dimensions |
|---|---|
| iPhone | 1320×2868px |
| iPad | 2064×2752px |
| Android phone | 1080×1920px |
| Android tablets (portrait) | 1200×1920 and 1600×2560 |
| Android tablets (landscape) | 1920×1200 and 2560×1600 |
| Google Play Feature Graphic | 1024×500px |
Layout Patterns
- Portrait phones: device centered, slightly lower than canvas center
- Landscape tablets: caption occupies left 34%, device on right with negative space
- Visual variation: layouts differ between adjacent slides to avoid templated feel
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.
- 1mo ago First seen · 104 lines · 47 tokens per session scan A 350776f11988
app-store-screenshots is a skill published in the GitHub repository ariadoss/superskills (12 stars, last pushed 3d ago), licensed MIT. It adds 47 tokens to every session and 786 once invoked, about $0.0002 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 2026-08-31.
