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.

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 | $0.00066 | $0.04148 |
| Opus 5 | $0.00033 | $0.02074 |
| Sonnet 5 | $0.00013 | $0.00830 |
| Haiku 4.5 | $0.00007 | $0.00415 |
Grade C, and why
app-brand-identity scanned grade C with 1 finding 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

App Brand Identity
Create a complete brand identity system for Apple platform apps. Produces a wordmark, app icon, design token foundation, brand voice guidelines, and App Store marketing asset strategy. Use before apple-design — this skill creates the visual system that apple-design implements in SwiftUI.
Embody a product designer at Apple. Your brand will live on the App Store, in the Dock, in Spotlight results, and in screenshots on social media. Every decision must survive at 16×16 (menu bar) and 1280×800 (App Store feature). No generic startup aesthetics. No gradient blobs. No AI-slop.
When to Use
- Starting a new app and need a name, logo, or visual identity
- Renaming or rebranding an existing app
- Designing the app icon (macOS rounded rect, iOS squircle, visionOS layered)
- Choosing typography, color palette, or spacing system
- Building a design token system that bridges marketing site and app code
- Preparing App Store screenshots, preview video storyboards, or feature graphics
- Creating a press kit or maker page
When NOT to Use
- Don't use for pure UI component design — that's
apple-design - Don't use for App Store submission logistics — that's
asc-submission - Don't use for pricing decisions — that's
app-store-pricing - Don't use for architecture diagrams — that's

The Brand Identity Process
1. Discovery & Constraints
Before designing, lock the constraints:
| Question | Why It Matters |
|---|---|
| Platforms? | macOS icons are rounded rect (≤ 1024pt). iOS is squircle (superellipse mask). visionOS is circular with layered depth. |
| Minimum OS? | iOS/macOS 26+ unlocks Liquid Glass, SF Rounded, new material effects. |
| Category? | Utility apps need instant recognition. Creative tools can be more expressive. Productivity apps should feel calm and competent. |
| Competitive frame? | Who do you want to be compared to? Who do you want to avoid being compared to? |
| Name length? | Short names (< 6 chars) allow larger wordmarks. Long names need abbreviation strategies. |
| Dark mode default? | macOS utilities often live in dark mode. iOS apps see both. |
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-brand-identity is a skill published in the GitHub repository markdavidgan/apple-dev-skills (5 stars, last pushed 12d ago), licensed MIT. It adds 66 tokens to every session and 4,148 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions).
