## What it does

This skill acts as a category index for Apple platform security. General documentation on Keychain storage, biometric authentication, certificate pinning, and ATS was retired after blind testing confirmed modern models handle those topics natively. The index keeps only specialized areas where models still fail.

All active routing points to `privacy-manifests`. That skill handles `PrivacyInfo.xcprivacy` configuration, required-reason API usage, App Tracking Transparency declarations, and App Store submission checks. It inspects source trees using `Read`, `Glob`, and `Grep`.

Do not expect standard biometric code snippets here; the skill focuses strictly on App Store privacy manifests and tracking declarations.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill security -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/security/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/security/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill security -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/security/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill security -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/security/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install rshankras/claude-code-apple-skills security
```

2. **Manually: put the files in place**
- File: `.github/skills/security/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill security -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/rshankras/claude-code-apple-skills --path skills/security
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/security/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add rshankras/claude-code-apple-skills --skill security -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/rshankras/claude-code-apple-skills/tree/HEAD/skills/security/SKILL.md

## When to use it
- inspect PrivacyInfo.xcprivacy files for App Store submissions
- audit source code for required-reason API usage
- configure App Tracking Transparency declarations
- route agent security prompts to privacy manifest guidelines

## Example prompts
- Audit our iOS project for required-reason APIs and PrivacyInfo.xcprivacy requirements
- Check if our App Tracking Transparency declarations match App Store submission rules

# Security (category index)

General security guidance (Keychain patterns, biometric auth, certificate
pinning, ATS) was removed from this library after the 2026-07 blind-test
audit confirmed current models answer it correctly without a skill
(`tools/skill-audit/`, Fable-verified coverage 0.86). What remains here is
the material models get wrong or can't know.

## Available Skills

### privacy-manifests/
Privacy manifest audit — PrivacyInfo.xcprivacy format, required-reason APIs,
App Tracking Transparency declarations, and App Store submission requirements.
```
