Deep Link Contract Repair

The problem

Deep-link behavior often drifts across platforms, causing universal links to land on Home, auth handoffs to lose destinations, and legacy URLs to fail. Managing disparate route registries for web, iOS, and Android without a canonical contract leads to broken navigation and security risks like open redirects.

What it does

• Identifies and repairs routing drift between web route registries and mobile navigation configurations.
• Fixes authentication handoffs to ensure users reach their intended destination after login or magic-link consumption.
• Resolves parameter encoding issues and double-decoding bugs across different platform URI parsers.
• Normalizes legacy route aliases to map directly to canonical intents without recursive redirect loops.
• Synchronizes repository-based platform configurations like AASA templates, Android manifests, and assetlinks fixtures.

Frameworks & tools

React Native, Expo, Flutter, iOS (universal links, custom schemes), Android (App Links, intent filters), Next.js, and hybrid-app frameworks.

Why this beats prompting it yourself

This skill traces the entire link lifecycle from producer to consumer, handling edge cases like cold-start vs. warm-start navigation and deferred-link idempotency. It enforces a strict "decode once" boundary and tenant-safe resolution that generic prompts often overlook, preventing security regressions.

Use cases

• Fixing iOS universal links that open the app but fail to navigate to the specific content.
• Ensuring locale and campaign context survive the app-install process via deferred links.
• Hardening authentication callbacks to prevent arbitrary "next" URL redirects to untrusted hosts.
• Consolidating analytics route naming so web and mobile events share a stable identity.

Known limitations

Does not access live DNS, app store consoles, or production identity providers. It cannot verify if a live domain is correctly associated with an installed production app.
