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 | $0.00073 | $0.01468 |
| Opus 5 | $0.00036 | $0.00734 |
| Sonnet 5 | $0.00015 | $0.00294 |
| Haiku 4.5 | $0.00007 | $0.00147 |
Grade A, and why
swiftui-navigation-navigator 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 12d 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.

SwiftUI Navigation with Navigator
When assisting the user with SwiftUI navigation in a project that uses Navigator or the NavigatorUI library, follow the conventions and patterns below. The skill is agent-agnostic; apply it whenever the user mentions Navigator, NavigatorUI, SwiftUI navigation, deep linking, checkpoints, managed navigation stack, or navigation destinations.
When to use this skill
Apply this skill when the user:
- Mentions Navigator, NavigatorUI, or navigation in a Navigator-based codebase.
- Asks about SwiftUI navigation patterns (push, sheet, deep link, return to a screen).
- Works on deep linking, checkpoints, routes, or dismissible behavior.
- Defines or refactors NavigationDestination enums or ManagedNavigationStack usage.
Core conventions
- Destinations: Enums conforming to
NavigationDestination(Hashable + View). Provide abodythat returns the correct view for each case; use associated values for parameters. Do not useNavigationLink(value:label:)orNavigationLink(destination:label:)for destination-driven navigation when using Navigator's no-registration flow. - Links: Use
NavigationLink(to: SomeDestination.case, label: { ... }), or the text shorthandNavigationLink("Title", to: SomeDestination.case)(Navigator 2.1.2+; title may be aString,LocalizedStringKey, orLocalizedStringResource). Navigator wraps the value internally; no per-typenavigationDestination(for: MyType.self)registration is required. - Stack: Use
ManagedNavigationStack { ... }where aNavigationStackwould go. It provides theNavigatorin the environment and a single internal registration for allNavigationDestinationtypes. - Navigator access: Use
@Environment(\.navigator) var navigator. Use the navigator for the current stack (from the closure ofManagedNavigationStackor from a child view). Do not assume the environment navigator is the root when inside a tab or presented view—it is the navigator for that stack.
What ships with it
6 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.

swiftui-navigation-navigator is a skill published in the GitHub repository hmlongco/Navigator (540 stars, last pushed 15d ago), licensed MIT. It adds 73 tokens to every session and 1,468 once invoked, about $0.0004 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 2026-08-30.
