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 | $0.00078 | $0.01661 |
| Opus 5.5 | $0.00031 | $0.00664 |
| Sonnet 5.5 | $0.00016 | $0.00332 |
| Haiku 4.5 | $0.00008 | $0.00166 |
Grade A, and why
creating-module 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 1mo 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 — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Creating Module
Add a new top-level navigation module to the app. Modules replace the entire screen hierarchy — they are not pushed or presented, they swap the whole view tree.
Existing Modules
The app ships with two modules:
| Module | ID | Content |
|---|---|---|
| Onboarding | Constants.onboardingModuleId |
onboardingFlow() — WelcomeView → sign in/up → OnboardingCompletedView |
| Tabbar | Constants.tabbarModuleId |
coreModuleTabBarView() — TabBarView with Home, Beta, Profile tabs |
ModuleWrapperView
Every module is wrapped in a ModuleWrapperView — a shared component that provides deep link (.onOpenURL) and push notification (.onNotificationReceived) handling at the module level.
Files — Core/ModuleWrapper/:
| File | Purpose |
|---|---|
ModuleWrapperView.swift |
View wrapper + ModuleWrapperDelegate struct + CoreBuilder extension |
ModuleWrapperPresenter.swift |
Handles deep link and push notification routing |
ModuleWrapperInteractor.swift |
Protocol extending GlobalInteractor |
ModuleWrapperRouter.swift |
Protocol extending GlobalRouter |
ModuleWrapperDelegate carries the moduleId: String so deep link/push handlers know which module is active and can route accordingly.
WARNING: ModuleWrapperView does NOT have a NavigationStack. The presenter cannot use router.showScreen(.push). It can use .fullScreenCover, .sheet, showModal, showAlert, update interactor state, or post a notification. See the adding-deep-link skill for details.
The ModuleWrapper already exists in the starter project — you do not need to create it. You only need to wrap your module's content with moduleWrapperView(router:delegate:).
Steps
- Get the module name and purpose from the user (camelCase for ID, e.g.,
"admin","settings") - Add the module ID constant
- Create the entry view builder method
- Create the switch method on CoreRouter
- Add the starting module case in AppView (if applicable)
- Create the module's root content
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.

creating-module is a skill published in the GitHub repository SwiftfulThinking/SwiftfulStarterProject (74 stars, last pushed 7d ago), licensed MIT. It adds 78 tokens to every session and 1,661 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-04.
