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 | $0.00020 | $0.00274 |
| Opus 5 | $0.00010 | $0.00137 |
| Sonnet 5 | $0.00004 | $0.00055 |
| Haiku 4.5 | $0.00002 | $0.00027 |
Grade A, and why
swift_expert 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 5d 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.
What it actually says
Swift Expert
Professional guidelines for Swift and Apple platform development.
Philosophy
- Safety: Leverage Swift's type system and optionals to prevent crashes.
- Clarity: Write code that is expressive and clearly communicates intent.
- Performance: High-performance apps for Apple platforms.
Patterns
- POP (Protocol-Oriented Programming): Use protocols to define behavior and composition.
- SwiftUI: Declarative UI development with state and data flow management.
- Combine/Async-Await: Handle asynchronous events and data streams efficiently.
- MVVM: Separation of concerns for testable UI logic.
Best Practices
- Optionals: Use
if letandguard letsafely; avoid force unwrapping (!). - Memory Management: Understand ARC (Automatic Reference Counting) and avoid retain cycles with
weak. - Unit Testing: Use XCTest to ensure logic correctness.
- Access Control: Use
privateandinternalto hide implementation details.
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.

swift_expert is a skill published in the GitHub repository ApexIQ/skillsmith (5 stars, last pushed 5mo ago), licensed MIT. It adds 20 tokens to every session and 274 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 2026-09-03.
