Navigation Flow

Maintain UIKitPlus Navigation Flow

Use this LOCAL contributor skill for built-in UIKitPlus navigation source work.

Load the smallest decision-complete context

1. Start from UIKitPlus AGENTS.md and SKILL_INDEX.md.
2. Use NAVIGATION_SYSTEM.md as the primary owner.
3. Add only what the change needs:
   • RUNTIME_MODEL.md for lifecycle/deferred transitions;
   • PLATFORM_ABSTRACTION.md for iOS/tvOS/macOS separation;
   • FLUENT_CHAIN_CONTRACT.md for changed public configuration APIs.
4. Use SOURCE_MAP.md before broad source discovery.

Plan checklist

• Identify exact platform scope and current native navigation substrate.
• Identify push/pop or transition lifecycle behavior affected.
• Check fluent API compatibility for configuration changes.
• Check recognizer/delegate interactions when swipe-back behavior is involved.
• Distinguish local convenience behavior from a new global navigation policy.

Implementation rules

• Preserve platform-specific navigation separation.
• Keep transitions and navigation effects explicit; do not introduce hidden global behavior.
• Preserve fluent Self return semantics for public configuration methods.
• Keep lifecycle assumptions aligned with the current runtime owner.
• Preserve native navigation/delegate ownership unless architecture is explicitly re-opened.

Audit

Verify:

• intentional platform divergence remains correct;
• swipe-back gating/delegate behavior is preserved when in scope;
• transition helpers remain explicit opt-in APIs;
• no platform leakage appears in shared contracts;
• fluent/reference semantics remain intact;
• unrelated source/governance remains untouched.

Stop and re-plan if the work requires a new navigation lifecycle/coordination model rather than an implementation inside the existing architecture.
