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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00163 | $0.05041 |
| Opus 5 | $0.00081 | $0.02521 |
| Sonnet 5 | $0.00033 | $0.01008 |
| Haiku 4.5 | $0.00016 | $0.00504 |
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 10d 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 — 458 lines — stays where its author put it; the contents beside it link to each section on GitHub.
App Store Screenshots Generator
Overview
Build a Next.js page that renders iOS App Store screenshots as advertisements (not UI showcases) and exports them via html-to-image at Apple's required resolutions. Screenshots are the single most important conversion asset on the App Store.
Reads
brand/creative-kit.md— Brand colors, fonts, logo pathsbrand/voice-profile.md— Copy tone and personalitybrand/positioning.md— Positioning angles for headline direction
On Activation
- Read
brand/creative-kit.mdfor colors, fonts, and logo. - Read
brand/voice-profile.mdfor copy tone — this shapes headline style (playful vs. professional vs. minimal). - Read
brand/positioning.mdfor positioning angles — the primary angle informs the hero slide headline direction. - If brand/ files don't exist, the skill works at zero context. Step 1 gathers everything needed.
Core Principle
Screenshots are advertisements, not documentation. Every screenshot sells one idea. If you're showing UI, you're doing it wrong — you're selling a feeling, an outcome, or killing a pain point.
Step 1: Ask the User
If brand/ files provided answers (colors, fonts, voice tone), confirm them with the user and skip those questions. Only ask what's genuinely unknown. Do not proceed until you have all answers:
Required
- App screenshots — "Where are your app screenshots? (PNG files of actual device captures)"
- App icon — "Where is your app icon PNG?"
- Brand colors — "What are your brand colors? (accent color, text color, background preference)"
- Font — "What font does your app use? (or what font do you want for the screenshots?)"
- Feature list — "List your app's features in priority order. What's the #1 thing your app does?"
- Number of slides — "How many screenshots do you want? (Apple allows up to 10)"
- Style direction — "What style do you want? Examples: warm/organic, dark/moody, clean/minimal, bold/colorful, gradient-heavy, flat. Share App Store screenshot references if you have any."
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

app-store-screenshots is a skill published in the GitHub repository MoizIbnYousaf/marketing-cli (31 stars, last pushed 23d ago), licensed MIT. It adds 163 tokens to every session and 5,041 once invoked, about $0.0008 per session on Opus 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 2026-08-30.
