-# Tool Decoupling Refactoring Plan
-
-## Current State Analysis
-
-**Where we are:**
-- New `openhands/tools/` module with unified Tool architecture (✅ committed)
-- Existing tools scattered in `openhands/agenthub/codeact_agent/tools/` (old approach)
-- Function calling logic hardcoded in `function_calling.py` with manual validation
-- Multiple agents (codeact, loc, readonly) each have their own function_calling.py
-- Tool schemas defined as dictionaries in individual tool files
-
-**Key Integration Points:**
-1. `openhands/agenthub/codeact_agent/function_calling.py` - main function call processor
-2. `openhands/agenthub/codeact_agent/codeact_agent.py` - imports tools for schema generation
-3. `openhands/agenthub/loc_agent/function_calling.py` - similar pattern
-4. `openhands/agenthub/readonly_agent/function_calling.py` - similar pattern
-
-## Target State
-
-**Where we need to get to:**
-- All agents use the new Tool classes for consistent behavior
-- Function calling delegates to `Tool.validate_function_call()` for parameter validation
-- Tool schemas come from `Tool.get_schema()`
-- Action creation remains in function_calling.py (simple, no over-abstraction)
-- Remove duplicated tool logic across agents
-- **No registry needed** - agents directly import and use the tools they need
-
-## Minimal Refactoring Strategy
-
-### Phase 1: Create Bridge Layer (Non-breaking)
-**Goal:** Make new tools work alongside existing system without breaking anything
-
-1. **Create tool adapter in function_calling.py**
-   - Add import for new `openhands.tools` (BashTool, FileEditorTool, etc.)
-   - Create helper function `validate_with_new_tools()` that attempts new tool validation
-   - Fall back to existing hardcoded logic if tool not found
-   - This allows gradual migration without breaking existing functionality
-
-2. **Update tool imports in codeact_agent.py**
-   - Import new Tool classes alongside existing tool imports
-   - Modify `get_tools()` method to include schemas from both old and new tools
-   - Ensure no duplicate tool names
-
-### Phase 2: Migrate Core Tools (One by one)
-**Goal:** Replace existing tools with new implementations
-
-1. **Start with bash tool (lowest risk)**
-   - Update function_calling.py to use BashTool for execute_bash calls
-   - Remove old bash tool logic once confirmed working
-   - Keep old bash.py file temporarily for reference
-
-2. **Migrate str_replace_editor tool**
-   - Update function_calling.py to use FileEditorTool
-   - Remove complex str_replace_editor logic from function_calling.py
-   - Keep old str_replace_editor.py temporarily
-
-3. **Migrate remaining tools one by one**
-   - finish, browser, think, ipython, condensation_request
-   - Each migration should be a separate commit for easy rollback
-
-### Phase 3: Clean Up (Remove old code)
-**Goal:** Remove duplicate/obsolete code
-
-1. **Remove old tool files**
-   - Delete `openhands/agenthub/codeact_agent/tools/` directory
-   - Update imports in codeact_agent.py
-
-2. **Simplify function_calling.py**
-   - Remove all hardcoded tool logic
-   - Replace with simple registry lookup and delegation
-   - Should be ~50 lines instead of ~250 lines
-
-### Phase 4: Extend to Other Agents (Optional)
-**Goal:** Apply same pattern to loc_agent and readonly_agent
-
-1. **Update loc_agent and readonly_agent**
-   - Replace their function_calling.py with registry-based approach
-   - Reuse same tool implementations
-
-## Implementation Details
-
-### Bridge Function (Phase 1)
-```python
-def validate_with_new_tools(tool_call):
-    """Try new tool classes for validation, fall back to old logic"""
-    from openhands.tools import BashTool, FileEditorTool
-
-    # Map tool names to tool instances
-    tools = {
-        'execute_bash': BashTool(),
-        'str_replace_editor': FileEditorTool(),
-    }
-
-    tool = tools.get(tool_call.function.name)
-    if tool:
-        try:
-            return tool.validate_function_call(tool_call.function)
-        except ToolValidationError as e:
-            raise FunctionCallValidationError(str(e))
-
-    # Fall back to existing hardcoded validation
-    return None  # Signal to use old logic
-```
-
-### Simplified function_calling.py (Phase 3)
-```python
-def response_to_actions(response: ModelResponse, mcp_tool_names: list[str] | None = None) -> list[Action]:
-    """Convert LLM response to OpenHands actions using new tool classes"""
-    from openhands.tools import BashTool, FileEditorTool
-
-    # Create tool instances (could be module-level for efficiency)
-    tools = {
-        'execute_bash': BashTool(),
-        'str_replace_editor': FileEditorTool(),
-    }
-
-    actions = []
-    # ... existing response parsing logic ...
-
-    for tool_call in assistant_msg.tool_calls:
-        tool = tools.get(tool_call.function.name)
-        if tool:
-            # Validate parameters using tool
-            try:
-                validated_params = tool.validate_function_call(tool_call.function)
-            except ToolValidationError as e:
-                raise FunctionCallValidationError(str(e))
-
-            # Create action based on tool type (simple logic remains here)
-            if tool_call.function.name == 'execute_bash':
-                action = CmdRunAction(command=validated_params['command'], ...)
-            elif tool_call.function.name == 'str_replace_editor':
-                action = FileEditAction(path=validated_params['path'], ...)
-            # ... etc for other tools
-
-            actions.append(action)
-        elif mcp_tool_names and tool_call.function.name in mcp_tool_names:
-            # Handle MCP tools
-            actions.append(MCPAction(...))
-        else:
-            raise FunctionCallNotExistsError(f'Tool {tool_call.function.name} not found')
-
-    return actions
-```
-
-## Risk Mitigation
-
-1. **Incremental approach** - Each phase can be tested independently
-2. **Backward compatibility** - Bridge layer ensures nothing breaks during transition
-3. **Easy rollback** - Each tool migration is a separate commit
-4. **Minimal changes** - Don't touch agent logic, only function calling layer
-5. **Keep it simple** - Don't over-engineer, just replace existing functionality
-
-## Success Criteria
-
-- [ ] All existing tests pass
-- [ ] Function calling behavior unchanged from user perspective
-- [ ] Tool logic consolidated in single location
-- [ ] Easy to add new tools by extending Tool base class
-- [ ] Reduced code duplication across agents
-- [ ] Cleaner, more maintainable codebase

-# OpenHands Tool Decoupling - Complete Implementation Plan
-
-## 🎯 Goal
-Decouple AI agent tools into their own classes to encapsulate tool definitions, error validation, and response interpretation separate from regular agent LLM response processing.
-
-## 📊 Current Status: CRITICAL MILESTONE ACHIEVED ✅
-
-**function_calling.py Migration Complete**: Successfully migrated CodeActAgent to use unified tool validation for all 4 core tools!
-
-### 🏗️ Architecture Summary
-- **CodeActAgent**: 4 base tools (BashTool, FileEditorTool, BrowserTool, FinishTool)
-- **ReadOnlyAgent**: Inherits FinishTool + adds 3 safe tools (ViewTool, GrepTool, GlobTool)
-- **LocAgent**: Inherits all CodeAct tools + adds 3 search tools (SearchEntityTool, SearchRepoTool, ExploreStructureTool)
-
-### 🚀 Migration Achievement: function_calling.py Complete
-- ✅ **Fixed legacy tool import conflicts** with proper aliasing (LegacyBrowserTool, LegacyFinishTool)
-- ✅ **Updated BrowserTool interface** to match legacy (code parameter instead of action)
-- ✅ **All 4 core tools using unified validation**:
-  - BashTool: `validate_parameters()` with proper error handling
-  - FinishTool: `validate_parameters()` with parameter mapping (summary/outputs)
-  - FileEditorTool: `validate_parameters()` with command handling (view/edit)
-  - BrowserTool: `validate_parameters()` with code parameter validation
-- ✅ **Fixed tool name constant references** throughout function_calling.py
-- ✅ **Created comprehensive integration tests** verifying tool validation works
-- ✅ **Maintained backward compatibility** with legacy fallback paths
-
-### 🧪 Testing Status
-- **192 total tests** (all passing)
-- **Integration tests passing** for all 4 core tools
-- **163 original tests**: Base Tool class, validation, error handling, inheritance patterns
-- **29 new LocAgent tests**: Complete coverage of search tools and inheritance
-
-### 🔧 Implementation Status
-- ✅ **Tool base class** with abstract methods and validation framework
-- ✅ **CodeAct tools** with full parameter validation and schema generation
-- ✅ **ReadOnly tools** with inheritance pattern and safety validation
-- ✅ **LocAgent tools** with complex parameter validation and search capabilities
-- ✅ **Comprehensive test suite** covering all tools and edge cases
-- ✅ **CodeActAgent function_calling.py migration** with unified tool validation
-
-## Architecture Decision: Agent-Specific Tool Organization
-
-After exploring the codebase, we discovered that **agent-specific tool organization** is the correct approach because:
-
-1. **CodeActAgent** is the base agent with comprehensive tools (bash, file editing, browsing, etc.)
-2. **ReadOnlyAgent** and **LocAgent** inherit from CodeActAgent but completely override `_get_tools()`
-3. Each agent has its own `tools/` directory and `function_calling.py` module
-4. Child agents can selectively inherit parent tools and add their own
-
-## Current Architecture
-

-- [x] All agent-specific tool architectures complete
-
-### 🔄 IN PROGRESS (Phase 3: Integration & Migration)
-- ✅ **CodeActAgent function_calling.py migration** (COMPLETED!)
-- [ ] ReadOnlyAgent function_calling.py migration (NEXT)
-- [ ] LocAgent function_calling.py migration (NEXT)
-
-### 📋 TODO (Phase 3: Full Migration)
-- [ ] Remove old tool definitions after migration complete
-- [ ] Documentation and cleanup
-- [ ] Performance testing and optimization
-
-## Detailed Implementation Plan
-
-### Phase 2: Testing & Integration (CURRENT)
-
-#### 2.1 Comprehensive Unit Tests (IMMEDIATE)
-Create `tests/unit/tools/` with complete test coverage:
-
-**Base Infrastructure Tests:**
-- `test_base_tool.py` - Tool base class, validation, error handling
-- `test_tool_inheritance.py` - Agent inheritance patterns
-
-**CodeAct Tool Tests:**
-- `test_bash_tool.py` - BashTool schema and validation
-- `test_file_editor_tool.py` - FileEditorTool schema and validation
-- `test_browser_tool.py` - BrowserTool schema and validation
-- `test_finish_tool.py` - FinishTool schema and validation
-
-**ReadOnly Tool Tests:**
-- `test_view_tool.py` - ViewTool schema and validation
-- `test_grep_tool.py` - GrepTool schema and validation
-- `test_glob_tool.py` - GlobTool schema and validation
-
-**Integration Tests:**
-- `test_agent_tool_integration.py` - Agent-specific tool loading
-- `test_function_call_validation.py` - End-to-end function call processing
-
-#### 2.2 Bridge Layer Implementation
-- Create adapter functions in each agent's function_calling.py
-- Gradual migration: new tools alongside existing ones
-- Validation layer that uses new Tool classes
-
-#### 2.3 Integration Points
-- Update `openhands/agenthub/codeact_agent/function_calling.py`
-- Update `openhands/agenthub/readonly_agent/function_calling.py`
-- Ensure backward compatibility during transition
-
-### Phase 3: Full Migration
-
-#### 3.1 LocAgent Tool Organization ✅
-```
-openhands/agenthub/loc_agent/tools/unified/
-├── __init__.py                    # Inherit from CodeAct + add search tools
-├── search_entity_tool.py          # SearchEntityTool for entity retrieval
-├── search_repo_tool.py            # SearchRepoTool for code snippet search
-└── explore_structure_tool.py      # ExploreStructureTool for dependency analysis
-```
-
-#### 3.2 Complete Migration
-- Replace all old tool definitions with new unified classes
-- Update all function_calling.py modules
-- Remove legacy tool code
-- Update agent `_get_tools()` methods to use new architecture
-
-#### 3.3 Cleanup & Documentation
-- Remove unused tool files
-- Update documentation
-- Add migration guide for future tool additions
-
-## Key Benefits of This Architecture
-
-1. **Encapsulation**: Tool logic separated from agent processing
-2. **Inheritance**: Child agents can reuse parent tools selectively
-3. **Validation**: Centralized parameter validation with clear error messages
-4. **Extensibility**: Easy to add new tools or modify existing ones
-5. **Type Safety**: Proper typing and schema validation
-6. **Testing**: Each tool can be unit tested independently
-
-## Testing Strategy
-
-### Unit Test Coverage Requirements
-- **Schema Generation**: Verify correct LiteLLM-compatible schemas
-- **Parameter Validation**: Test all validation rules and edge cases
-- **Error Handling**: Test all error conditions and messages
-- **Inheritance**: Verify child agents can inherit and extend parent tools
-- **Integration**: Test function call processing end-to-end
-
-### Test Categories
-1. **Positive Tests**: Valid inputs produce expected outputs
-2. **Negative Tests**: Invalid inputs produce appropriate errors
-3. **Edge Cases**: Boundary conditions, empty values, type mismatches
-4. **Integration Tests**: Agent-tool interaction, function calling flow
-
-## Migration Strategy
-
-1. **Parallel Implementation**: New tools alongside existing ones
-2. **Gradual Adoption**: Migrate one agent at a time
-3. **Backward Compatibility**: Maintain existing functionality during transition
-4. **Validation**: Comprehensive testing at each step
-5. **Cleanup**: Remove old code only after full migration
-
-## Success Criteria
-
-- [ ] All agents use unified tool architecture
-- [ ] 100% test coverage for tool functionality
-- [ ] No regression in existing functionality
-- [ ] Clear separation of concerns between tools and agents
-- [ ] Easy to add new tools or modify existing ones
-- [ ] Comprehensive error handling and validation
-

-### Command Execution
-* One command at a time: You can only execute one bash command at a time. If you need to run multiple commands sequentially, use `&&` or `;` to chain them together.
-* Persistent session: Commands execute in a persistent shell session where environment variables, virtual environments, and working directory persist between commands.
-* Soft timeout: Commands have a soft timeout of 10 seconds, once that's reached, you have the option to continue or interrupt the command (see section below for details)
-
-### Long-running Commands
-* For commands that may run indefinitely, run them in the background and redirect output to a file, e.g. `python3 app.py > server.log 2>&1 &`.
-* For commands that may run for a long time (e.g. installation or testing commands), or commands that run for a fixed amount of time (e.g. sleep), you should set the "timeout" parameter of your function call to an appropriate value.
-* If a bash command returns exit code `-1`, this means the process hit the soft timeout and is not yet finished. By setting `is_input` to `true`, you can:
-  - Send empty `command` to retrieve additional logs
-  - Send text (set `command` to the text) to STDIN of the running process
-  - Send control commands like `C-c` (Ctrl+C), `C-d` (Ctrl+D), or `C-z` (Ctrl+Z) to interrupt the process
-  - If you do C-c, you can re-start the process with a longer "timeout" parameter to let it run to completion
-
-### Best Practices
-* Directory verification: Before creating new directories or files, first verify the parent directory exists and is the correct location.
-* Directory management: Try to maintain working directory by using absolute paths and avoiding excessive use of `cd`.
-
-### Output Handling
-* Output truncation: If the output exceeds a maximum length, it will be truncated before being returned."""

For commands that need to run for a specific duration, you can set the "timeout" argument to specify a hard timeout in seconds.
-* Interact with running process: If a bash command returns exit code `-1`, this means the process is not yet finished. By setting `is_input` to `true`, the assistant can interact with the running process and send empty `command` to retrieve any additional logs, or send additional text (set `command` to the text) to STDIN of the running process, or send command like `C-c` (Ctrl+C), `C-d` (Ctrl+D), `C-z` (Ctrl+Z) to interrupt the process.

-* State is persistent across command calls and discussions with the user
-* If `path` is a text file, `view` displays the result of applying `cat -n`. If `path` is a directory, `view` lists non-hidden files and directories up to 2 levels deep
-* The following binary file extensions can be viewed in Markdown format: [".xlsx", ".pptx", ".wav", ".mp3", ".m4a", ".flac", ".pdf", ".docx"]. IT DOES NOT HANDLE IMAGES.
-* The `create` command cannot be used if the specified `path` already exists as a file
-* If a `command` generates a long output, it will be truncated and marked with `<response clipped>`
-* The `undo_edit` command will revert the last edit made to the file at `path`
-* This tool can be used for creating and editing files in plain-text format.
-
-
-Before using this tool:
-1. Use the view tool to understand the file's contents and context
-2. Verify the directory path is correct (only applicable when creating new files):
-   - Use the view tool to verify the parent directory exists and is the correct location
-
-When making edits:
-   - Ensure the edit results in idiomatic, correct code
-   - Do not leave the code in a broken state
-   - Always use absolute file paths (starting with /)
-
-CRITICAL REQUIREMENTS FOR USING THIS TOOL:
-
-1. EXACT MATCHING: The `old_str` parameter must match EXACTLY one or more consecutive lines from the file, including all whitespace and indentation. The tool will fail if `old_str` matches multiple locations or doesn't match exactly with the file content.
-
-2. UNIQUENESS: The `old_str` must uniquely identify a single instance in the file:
-   - Include sufficient context before and after the change point (3-5 lines recommended)
-   - If not unique, the replacement will not be performed
-
-3. REPLACEMENT: The `new_str` parameter should contain the edited lines that replace the `old_str`. Both strings must be different.
-
-Remember: when making multiple file edits in a row to the same file, you should prefer to send all edits in a single message with multiple calls to this tool, rather than multiple messages with a single call each."""

-The search can be controlled to traverse upstream (exploring dependencies that entities rely on) or downstream (exploring how entities impact others), with optional limits on traversal depth and filters for entity and dependency types.
-
-Code Graph Definition:
-* Entity Types: 'directory', 'file', 'class', 'function'.
-* Dependency Types: 'contains', 'imports', 'invokes', 'inherits'.
-* Hierarchy:
-    - Directories contain files and subdirectories.
-    - Files contain classes and functions.
-    - Classes contain inner classes and methods.
-    - Functions can contain inner functions.
-* Interactions:
-    - Files/classes/functions can import classes and functions.
-    - Classes can inherit from other classes.
-    - Classes and functions can invoke others (invocations in a class's `__init__` are attributed to the class).
-Entity ID:
-* Unique identifier including file path and module path.
-* Here's an example of an Entity ID: `"interface/C.py:C.method_a.inner_func"` identifies function `inner_func` within `method_a` of class `C` in `"interface/C.py"`.
-
-Notes:
-* Traversal Control: The `traversal_depth` parameter specifies how deep the function should explore the graph starting from the input entities.
-* Filtering: Use `entity_type_filter` and `dependency_type_filter` to narrow down the scope of the search, focusing on specific entity types and relationships.

-### Command Execution
-* One command at a time: You can only execute one bash command at a time. If you need to run multiple commands sequentially, use `&&` or `;` to chain them together.
-* Persistent session: Commands execute in a persistent shell session where environment variables, virtual environments, and working directory persist between commands.
-* Soft timeout: Commands have a soft timeout of 10 seconds, once that's reached, you have the option to continue or interrupt the command (see section below for details)
-
-### Long-running Commands
-* For commands that may run indefinitely, run them in the background and redirect output to a file, e.g. `python3 app.py > server.log 2>&1 &`.
-* For commands that may run for a long time (e.g. installation or testing commands), or commands that run for a fixed amount of time (e.g. sleep), you should set the "timeout" parameter of your function call to an appropriate value.
-* If a bash command returns exit code `-1`, this means the process hit the soft timeout and is not yet finished. By setting `is_input` to `true`, you can:
-  - Send empty `command` to retrieve additional logs
-  - Send text (set `command` to the text) to STDIN of the running process
-  - Send control commands like `C-c` (Ctrl+C), `C-d` (Ctrl+D), or `C-z` (Ctrl+Z) to interrupt the process
-  - If you do C-c, you can re-start the process with a longer "timeout" parameter to let it run to completion
-
-### Best Practices
-* Directory verification: Before creating new directories or files, first verify the parent directory exists and is the correct location.
-* Directory management: Try to maintain working directory by using absolute paths and avoiding excessive use of `cd`.
-
-### Output Handling
-* Output truncation: If the output exceeds a maximum length, it will be truncated before being returned."""

For commands that need to run for a specific duration, you can set the "timeout" argument to specify a hard timeout in seconds.
-* Interact with running process: If a bash command returns exit code `-1`, this means the process is not yet finished. By setting `is_input` to `true`, the assistant can interact with the running process and send empty `command` to retrieve any additional logs, or send additional text (set `command` to the text) to STDIN of the running process, or send command like `C-c` (Ctrl+C), `C-d` (Ctrl+D), `C-z` (Ctrl+Z) to interrupt the process.

-* State is persistent across command calls and discussions with the user
-* If `path` is a text file, `view` displays the result of applying `cat -n`. If `path` is a directory, `view` lists non-hidden files and directories up to 2 levels deep
-* The following binary file extensions can be viewed in Markdown format: [".xlsx", ".pptx", ".wav", ".mp3", ".m4a", ".flac", ".pdf", ".docx"]. IT DOES NOT HANDLE IMAGES.
-* The `create` command cannot be used if the specified `path` already exists as a file
-* If a `command` generates a long output, it will be truncated and marked with `<response clipped>`
-* The `undo_edit` command will revert the last edit made to the file at `path`
-* This tool can be used for creating and editing files in plain-text format.
-
-
-Before using this tool:
-1. Use the view tool to understand the file's contents and context
-2. Verify the directory path is correct (only applicable when creating new files):
-   - Use the view tool to verify the parent directory exists and is the correct location
-
-When making edits:
-   - Ensure the edit results in idiomatic, correct code
-   - Do not leave the code in a broken state
-   - Always use absolute file paths (starting with /)
-
-CRITICAL REQUIREMENTS FOR USING THIS TOOL:
-
-1. EXACT MATCHING: The `old_str` parameter must match EXACTLY one or more consecutive lines from the file, including all whitespace and indentation. The tool will fail if `old_str` matches multiple locations or doesn't match exactly with the file content.
-
-2. UNIQUENESS: The `old_str` must uniquely identify a single instance in the file:
-   - Include sufficient context before and after the change point (3-5 lines recommended)
-   - If not unique, the replacement will not be performed
-
-3. REPLACEMENT: The `new_str` parameter should contain the edited lines that replace the `old_str`. Both strings must be different.
-
-Remember: when making multiple file edits in a row to the same file, you should prefer to send all edits in a single message with multiple calls to this tool, rather than multiple messages with a single call each."""

-* If the `old_str` parameter is not unique in the file, the replacement will not be performed. Make sure to include enough context in `old_str` to make it unique

-# OpenHands End-to-End Tests
-
-This directory contains end-to-end tests for the OpenHands application. These tests use Playwright to interact with the OpenHands UI and verify that the application works correctly.
-
-## Running the Tests
-
-### Prerequisites
-
-- Python 3.12 or later
-- Poetry
-- Node.js
-- Playwright
-
-### Environment Variables
-
-The following environment variables are required:
-
-- `GITHUB_TOKEN`: A GitHub token with access to the repositories you want to test
-- `LLM_MODEL`: The LLM model to use (e.g., "gpt-4o")
-- `LLM_API_KEY`: The API key for the LLM model
-
-Optional environment variables:
-
-- `LLM_BASE_URL`: The base URL for the LLM API (if using a custom endpoint)
-
-### Running Locally
-
-To run the full end-to-end test suite locally:
-
-```bash
-cd tests/e2e
-poetry run pytest test_e2e_workflow.py -v
-```
-
-This runs all tests in sequence:
-1. GitHub token configuration
-2. Conversation start
-
-### Running Individual Tests
-
-You can run individual tests directly:
-
-```bash
-cd tests/e2e
-# Run the GitHub token configuration test
-poetry run pytest test_e2e_workflow.py::test_github_token_configuration -v
-
-# Run the conversation start test
-poetry run pytest test_e2e_workflow.py::test_conversation_start -v
-
-
-```
-
-### Running with Visible Browser
-
-To run the tests with a visible browser (non-headless mode) so you can watch the browser interactions:
-
-```bash
-cd tests/e2e
-poetry run pytest test_e2e_workflow.py::test_github_token_configuration -v --no-headless --slow-mo=50
-poetry run pytest test_e2e_workflow.py::test_conversation_start -v --no-headless --slow-mo=50
-```
-
-### GitHub Workflow
-
-The tests can also be run as part of a GitHub workflow. The workflow is triggered by:
-
-1. Adding the "end-to-end" label to a pull request
-2. Manually triggering the workflow from the GitHub Actions tab
-
-## Test Descriptions
-
-### GitHub Token Configuration Test
-
-The GitHub token configuration test (`test_github_token_configuration`) performs the following steps:
-
-1. Navigates to the OpenHands application
-2. Checks if the GitHub token is already configured:
-   - If not configured, it navigates to the settings page and configures it
-   - If already configured, it verifies the repository selection is available
-3. Verifies that the GitHub token is saved and the repository selection is available
-
-### Conversation Start Test
-
-The conversation start test (`test_conversation_start`) performs the following steps:
-
-1. Navigates to the OpenHands application (assumes GitHub token is already configured)
-2. Selects the "openhands-agent/OpenHands" repository
-3. Clicks the "Launch" button
-4. Waits for the conversation interface to load
-5. Waits for the agent to initialize
-6. Asks "How many lines are there in the main README.md file?"
-7. Waits for and verifies the agent's response
-
-
-
-### Simple Browser Navigation Test
-
-A simple test (`test_simple_browser_navigation`) that just navigates to the OpenHands GitHub repository to verify the browser setup works correctly.
-
-### Local Runtime Test
-
-A separate test (`test_headless_mode_with_dummy_agent_no_browser` in `test_local_runtime.py`) that tests the local runtime with a dummy agent in headless mode.
-
-## Troubleshooting
-
-If the tests fail, check the following:
-
-1. Make sure all required environment variables are set
-2. Check the logs in `/tmp/openhands-e2e-test.log` and `/tmp/openhands-e2e-build.log`
-3. Verify that the OpenHands application is running correctly
-4. Check the Playwright test results in the `test-results` directory
