+# Create Deeplink Handler
+
+Generate a new deeplink handler with all required boilerplate code, tests, and integration instructions.
+
+## Required Information
+
+Before generating, I need the following details:
+
+1. **Action Name** (kebab-case): The URL path segment (e.g., `my-feature` for `https://link.metamask.io/my-feature`)
+2. **URL Parameters**: List of query parameters to support (e.g., `id`, `type`, `source`)
+3. **Navigation Route**: The destination route constant (e.g., `Routes.MY_FEATURE.HOME`)
+4. **Whitelisting**: Should this action bypass the security interstitial? (default: no)
+
+---
+
+## Generation Tasks
+
+Using the guidelines from `.cursor/rules/deeplink-handler-guidelines.mdc`, generate the following:
+
+### 1. Handler File
+
+Create `app/core/DeeplinkManager/handlers/legacy/handle{PascalCaseName}Url.ts` with:
+
+- Proper TypeScript interfaces for params
+- URL parameter parsing function
+- Main handler function with try/catch and fallback
+- DevLogger usage for debugging
+- TSDoc documentation with supported URL formats
+
+### 2. Test File
+
+Create `app/core/DeeplinkManager/handlers/legacy/__tests__/handle{PascalCaseName}Url.test.ts` with:
+
+- Jest mocks for NavigationService and DevLogger
+- Test cases for:
+  - Navigation with no parameters
+  - Navigation with each individual parameter
+  - Navigation with all parameters combined
+  - Fallback to WALLET.HOME on error
+
+### 3. Integration Instructions
+
+After generating the files, provide exact code snippets for the manual integration steps:
+
+#### Step A: Add to ACTIONS enum
+
+Show the exact line to add to `app/constants/deeplinks.ts`
+
+#### Step B: Add to PREFIXES
+
+Show the exact line to add to the PREFIXES object
+
+#### Step C: Import handler
+
+Show the import statement for `handleUniversalLink.ts`
+
+#### Step D: Add to SUPPORTED_ACTIONS enum
+
+Show the exact line to add
+
+#### Step E: Add switch case (CRITICAL)
+
+Show the complete switch case block to add
+
+#### Step F: (Optional) Add to whitelist
+
+If whitelisting requested, show the line to add to WHITELISTED_ACTIONS
+
+### 4. Test Commands
+
+Provide ready-to-run commands:
+
+- Unit test command
+- iOS Simulator deeplink test
+- Android Emulator deeplink test
+
+### 5. Documentation Updates
+
+Remind to update:
+
+- `docs/readme/deeplinking.md` (add to Supported Actions table)
+- `docs/deeplink-test-urls.md` (add test URLs)
+
+---
+
+## Example Usage
+
+**User prompt**: "Create a deeplink handler for `stake` with parameters `validator` and `amount`, navigating to `Routes.STAKING.STAKE_INPUT`"
+
+**Expected output**:
+
+1. Generated `handleStakeUrl.ts` with validator and amount params
+2. Generated `handleStakeUrl.test.ts` with full test coverage
+3. Copy-paste integration snippets for all manual steps
+4. Test commands ready to run
