## Goal
Help me write playwright code with following functionalities:
- [[add semi-high level functionality you want here]]
- [[more]]
- [[more]]
- [[more]]
## Reference
- Use @x, @y files if you want to take reference on how I write POM code
## Steps
- First fetch the context from 'get-context' tool, until it returns no elements remaining
- Based on context and user functionality, write code in POM format, encapsulating high level functionality into reusable functions
- Try executing code using 'execute-code' tool. You could be on any page, so make sure to navigate to the correct page
- Write spec file using those reusable functions, covering multiple scenarios

text: `# Create New Testcase - Iterative Development Workflow
## Goal
Create a comprehensive testcase by building and validating code iteratively. Test each step before moving to the next.
## Prerequisites
1. **URL**: User must provide the platform URL to test
2. **Auth/Login Info**: Search the user's codebase for login credentials, auth patterns, or existing test data based on user's description
3. **Test Objective**: Clear description of what functionality to test
## Workflow
Follow this iterative approach - validate each step before proceeding:
### Step 1: Initialize & Navigate
- Use \`init-browser\` with the provided URL
- Take a screenshot to confirm page loaded correctly
### Step 2: Discover Interactive Elements
- Use \`get-interactive-snapshot\` to see all clickable/interactive elements
- Identify auth-related elements (login buttons, forms, etc.)
### Step 3: Build Code Incrementally
For each interaction needed:
- Write small code snippet for ONE action (click, fill, etc.)
- Use \`execute-code\` to test the snippet immediately
- If it works, add to your growing test code
- If it fails, debug and fix before moving on
- Take screenshots after major actions to verify state
### Step 4: Handle Authentication
- Look for login forms, auth buttons, or existing session handling
- Use codebase patterns if found, otherwise build step-by-step
- Validate each auth step works before proceeding
### Step 5: Test Core Functionality
- Continue iterative approach: write \u2192 test \u2192 validate \u2192 accumulate
- Use \`get-interactive-snapshot\` whenever you need to see current page state
- If you don't get element here, call \`get-full-snapshot\` but try to avoid it because it's too large generally
- Build up your working test code piece by piece
### Step 6: Create Final Test Structure
- Organize all working code snippets into a complete test
- Add proper assertions and error handling
- Include setup and cleanup steps
## Key Principles
- **Test EVERY code snippet** before adding to final test
- **Never assume** - always verify with \`execute-code\`
- **Build incrementally** - one working step at a time
- **Use snapshots** to understand current page state
- **Accumulate working code** as you validate each piece
## Expected Output
A complete, tested Playwright testcase that successfully achieves the user's testing objective.`

text: `# Debug Existing Testcase
## Goal
Fix a failing testcase by identifying issues and applying targeted fixes using iterative testing.
## Prerequisites
1. **Testcase Code**: User provides the failing test code
2. **Error Description**: What's failing or expected vs actual behavior
3. **Platform URL**: Where the test should run
## Workflow
### Step 1: Understand the Failure
- Review the provided testcase code
- Understand what it's supposed to do vs what's happening
- Identify the specific failure point
### Step 2: Set Up Environment
- Use \`init-browser\` to navigate to the test URL
- Take initial screenshot to see current state
### Step 3: Execute and Locate Failure Point
- Run the existing testcase using \`execute-code\`
- Note exactly where it fails (line/step)
- Use \`get-interactive-snapshot\` to see current page state at failure point
- If you don't get element here, call \`get-full-snapshot\` but try to avoid it because it's too large generally
### Step 4: Incremental Debugging
For the failing section:
- Break down the failing part into smaller steps
- Test each small step with \`execute-code\`
- Use snapshots to understand page state changes
- Identify root cause (element not found, wrong selector, timing issue, etc.)
### Step 5: Apply Targeted Fixes
- Fix the specific issue (update selectors, add waits, etc.)
- Test the fix in isolation with \`execute-code\`
- Verify it works before integrating back
### Step 6: Test Complete Flow
- Run the entire fixed testcase to ensure no regressions
- Verify all steps work end-to-end
- Take screenshots at key points to confirm expected behavior
## Common Debug Patterns
- **Selector Issues**: Use \`get-interactive-snapshot\` to find correct selectors
- **Timing Issues**: Add proper waits and verify element visibility
- **Page State**: Check if page state changed (new UI, different flow)
- **Auth Problems**: Verify login/session handling still works
## Expected Output
A corrected testcase that passes all steps and achieves the original testing objective.`
