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 | $0.00027 | $0.00543 |
| Opus 5 | $0.00014 | $0.00271 |
| Sonnet 5 | $0.00005 | $0.00109 |
| Haiku 4.5 | $0.00003 | $0.00054 |
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 8d 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 — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
│ ├── Privacy manifest → references/privacy-manifest.md
│ ├── Tracking, analytics → references/privacy-manifest.md
│ └── 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
- **Fix:** How to remediate
- **Reference:** Which reference doc

What ships with it
5 files 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.

ios-security is a skill published in the GitHub repository matiastripode/ios-agent-skills (2 stars, last pushed 5mo ago), licensed MIT. It adds 27 tokens to every session and 543 once invoked, about $0.0001 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.
