What is ios-security?

A security and privacy review for iOS apps written in Swift. It checks areas such as stored data, network requests, authentication, privacy settings, and the OWASP Mobile Top 10, a common list of mobile security risks.

Use it to review iOS code involving Keychain, UserDefaults, files, databases, APIs, authentication, tracking, privacy manifests, or required-reason APIs.

It helps find exposed secrets, unsafe data handling, network problems, and privacy compliance issues before they reach users.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00027	$0.00543
Opus 5.5	$0.00011	$0.00217
Sonnet 5.5	$0.00005	$0.00109
Haiku 4.5	$0.00003	$0.00054

Security

Grade A, and why

ios-security 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 2mo 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.

iOS Security

An agent skill for reviewing iOS/Swift code for security vulnerabilities, data protection issues, and privacy compliance.

When to Activate

User asks for a security review of iOS code
User asks about secure storage, networking, or authentication
User runs /ios-security-check
Code involves: Keychain, UserDefaults with sensitive data, networking, authentication, file storage, or privacy-related APIs

Decision Tree

What area of code is being reviewed?
├── Data Storage
│   ├── Credentials, tokens, secrets → references/keychain-usage.md
│   ├── Files, databases, backups → references/data-protection.md
│   └── UserDefaults → Flag if storing sensitive data
├── Networking
│   ├── API calls, URLSession → references/network-security.md
│   ├── Hardcoded URLs, API keys → references/network-security.md
│   └── ATS configuration → references/network-security.md
├── Privacy

│   └── Required reason APIs → references/privacy-manifest.md
└── General Security Audit
    └── Walk through references/owasp-mobile-top10.md

Severity Levels

CRITICAL: Direct data exposure, hardcoded secrets, no encryption on sensitive data
HIGH: Missing certificate pinning on auth endpoints, weak Keychain configuration
MEDIUM: Missing privacy manifest entries, ATS exceptions without justification
LOW: Debug logging of sensitive data, clipboard exposure

Output Format

### [SEVERITY] Finding Title
- **Category:** Storage / Networking / Privacy / Authentication
- **File:** path/to/file.swift:line
- **Risk:** What could go wrong

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.
