ax-privacy

ax-privacy is a skill for Claude Code from Kasempiternal/axiom-v2. It costs 57 tokens per session (6,155 once invoked), scanned A, original, MIT.

A set of guidance and code patterns for Apple app privacy, permissions, translation, drag-and-drop, sharing, and system integrations. It covers iOS and macOS features such as privacy manifests, App Intents, and Required Reason APIs.

In plain words
What is it for?
Use it when building or reviewing Swift and SwiftUI apps that request access, support multiple languages, exchange content, expose actions to Apple systems, or need privacy declarations.
Why use it?
It helps avoid common omissions in privacy declarations, permission flows, translated text, and Apple platform integrations. It also provides patterns for handling denied permissions and discoverability.

Token cost

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.

Security

Grade A, and why

ax-privacy 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 11d 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.

Privacy, Localization & App Integration

Quick Patterns

Privacy Manifest Setup

<!-- PrivacyInfo.xcprivacy -->
<key>NSPrivacyTracking</key>
<false/>
<key>NSPrivacyCollectedDataTypes</key>
<array><!-- Data types collected --></array>
<key>NSPrivacyAccessedAPITypes</key>
<array><!-- Required Reason APIs --></array>

Permission Request Flow

User triggers feature
+-- Show pre-permission education (your dialog)
    +-- User taps "Continue"
        +-- Show system permission dialog
            +-- Granted --> open feature
            +-- Denied  --> show Settings prompt (never dead-end)

Just-in-Time Permission

@objc func takePhotoButtonTapped() {
    showCameraEducation {
        AVCaptureDevice.requestAccess(for: .video) { granted in
            if granted { self.openCamera() }
            else { self.showSettingsPrompt() }
        }
    }
}

String Catalog Localization

// SwiftUI -- auto-localizable
Text("Welcome to WWDC!")
Label("Thanks for shopping!", systemImage: "bag")

// Explicit with comment
let title = String(localized: "Settings", comment: "Tab bar item title")

// Deferred lookup
struct CardView: View {
    let title: LocalizedStringResource
    var body: some View { Text(title) }
}

Transferable Type Decision

Model conforms to Codable?       --> CodableRepresentation
Custom binary format in memory?  --> DataRepresentation
Large file on disk?              --> FileRepresentation
Need fallback for simple types?  --> ProxyRepresentation (add last)

Drag and Drop

// Make draggable
Text(profile.name).draggable(profile)

// Accept drops
Color.clear
    .frame(width: 200, height: 200)
    .contentShape(Rectangle())
    .dropDestination(for: Profile.self) { profiles, location in
        guard let profile = profiles.first else { return false }
        self.droppedProfile = profile
        return true
    }

App Discoverability (6-Step Strategy)

1. App Intents      -- expose actions to Siri/Shortcuts
2. App Shortcuts    -- instant availability, suggested phrases
3. Core Spotlight   -- index searchable content
4. NSUserActivity   -- mark high-value screens
5. Clear metadata   -- action-oriented titles/descriptions
6. Usage boosting   -- promote with SiriTipView, let system learn

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.

ax-privacy is a skill published in the GitHub repository Kasempiternal/axiom-v2 (4 stars, last pushed 6mo ago), licensed MIT. It adds 57 tokens to every session and 6,155 once invoked, about $0.0003 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 2026-08-31.
