--allow-all --coverage=coverage test/\ndeno coverage coverage --html\n```\n\n## Test Categories\n\n### Component Tests\n\n- **Message.test.tsx**: Tests for the Message component including:\n - Basic rendering with different message types\n - Block content rendering (text, code, MCP tools)\n - Action button functionality\n - Props validation\n\n### Test Utilities\n\n- **test-helpers.ts**: Common utilities for creating mock data and assertions\n- **setup.ts**: Global test configuration and environment setup\n\n## Writing Tests\n\n### Basic Test Structure\n\n```typescript\nimport { assertEquals, assertExists } from \"https://deno.land/std@0.208.0/assert/mod.ts\";\nimport { render, cleanup } from \"https://esm.sh/@testing-library/react@14.0.0?deps=react@18.2.0,react-dom@18.2.0\";\n\nDeno.test(\"Component Name - Test Category\", async (t) => {\n await t.step(\"should do something specific\", () => {\n // Test implementation\n });\n \n // Cleanup after test\n cleanup();\n});\n```\n\n### Using Test Helpers\n\n```typescript\nimport { createMockMessage, createMockCallback } from \"../utils/test-helpers.ts\";\n\n// Create mock data\nconst message = createMockMessage({\n role: \"assistant\",\n content: \"Test content\"\n});\n\n// Create mock callbacks\nconst mockOnDelete = createMockCallback();\n```\n\n## Test Environment\n\nThe test environment includes:\n\n- **React Testing Library**: For component testing\n- **Deno Standard Library**: For assertions\n- **Mock DOM**: Simulated browser environment\n- **Mock APIs**: localStorage, fetch, crypto.randomUUID\n- **Test Helpers**: Utilities for creating mock data\n\n## Coverage\n\nTest coverage reports are generated in the `coverage/` directory when running coverage commands. The HTML report provides detailed information about:\n\n- Line coverage\n- Function coverage\n- Branch coverage\n- Uncovered code sections\n\n## Best Practices\n\n1. **Test Structure**: Use descriptive test names and group related tests\n2. **Cleanup**: Always cleanup after component tests\n3. **Mocking**: Use provided test helpers for consistent mock data\n4. **Assertions**: Use specific assertions that clearly indicate what's being tested\n5. **Isolation**: Each test should be independent and not rely on other tests\n\n## Adding New Tests\n\n1. Create test files in the appropriate subdirectory\n2. Follow the naming convention: `ComponentName.test.tsx`\n3. Import necessary testing utilities\n4. Use the established test structure and helpers\n5. Add cleanup calls for component tests\n6. Update this README if adding new test categories\n\n## Troubleshooting\n\n### Common Issues\n\n- **Import Errors**: Ensure all imports use the correct ESM URLs with React version pinning\n- **Component Not Rendering**: Check that all required props are provided\n- **Mock Issues**: Verify that mocks are properly set up in setup.ts\n- **Timeout Errors**: Increase timeout in test configuration if needed\n\n### Debug Tips\n\n- Use `console.log` in tests to debug values\n- Check the HTML output with `container.innerHTML`\n- Verify mock function calls with `mockFn.calls`\n- Use `--inspect` flag with Deno for debugging",[],[429,465],{"_108":473,"_100":474,"_152":475,"_154":430,"_155":139,"_156":476,"_158":159,"_110":477,"_105":31,"_161":200,"_163":478,"_164":27,"_165":-5,"_166":479,"_103":480},"c9996aaa-4ce4-11f0-9811-76b3cceeab13","setup.ts","c9996be0-4ce4-11f0-9811-76b3cceeab13",835,["D",1750320596692],"/**\n * Test setup and configuration for the Anthropic Streaming Chat MCP application\n * This file is automatically loaded before running tests\n */\n\n// Import polyfills and setup utilities\nimport { setupMockDOM } from \"./utils/test-helpers.ts\";\n\n// Global test setup\nconsole.log(\"🧪 Setting up test environment...\");\n\n// Setup mock DOM environment\nsetupMockDOM();\n\n// Mock crypto.randomUUID if not available\nif (!globalThis.crypto?.randomUUID) {\n globalThis.crypto = {\n ...globalThis.crypto,\n randomUUID: () => {\n return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {\n const r = Math.random() * 16 | 0;\n const v = c == 'x' ? r : (r & 0x3 | 0x8);\n return v.toString(16);\n });\n }\n };\n}\n\n// Mock localStorage for tests\nconst mockStorage = new Map();\n\nglobalThis.localStorage = {\n getItem: (key: string) => mockStorage.get(key) || null,\n setItem: (key: string, value: string) => mockStorage.set(key, value),\n removeItem: (key: string) => mockStorage.delete(key),\n clear: () => mockStorage.clear(),\n length: mockStorage.size,\n key: (index: number) => Array.from(mockStorage.keys())[index] || null,\n};\n\n// Mock fetch for API calls in tests\nconst originalFetch = globalThis.fetch;\nglobalThis.fetch = async (input: RequestInfo | URL, init?: RequestInit) => {\n // Log fetch calls during tests\n console.log(`🌐 Mock fetch called:`, { input, init });\n \n // Return mock responses for known endpoints\n const url = typeof input === 'string' ? input : input.toString();\n \n if (url.includes('/mcp')) {\n return new Response(JSON.stringify({ status: 'ok', tools: [] }), {\n status: 200,\n headers: { 'Content-Type': 'application/json' }\n });\n }\n \n // Fall back to original fetch for other requests\n if (originalFetch) {\n return originalFetch(input, init);\n }\n \n // Default mock response\n return new Response('Mock response', { status: 200 });\n};\n\n// Mock console methods for cleaner test output (optional)\nconst originalConsoleLog = console.log;\nconst originalConsoleError = console.error;\nconst originalConsoleWarn = console.warn;\n\n// Uncomment to suppress console output during tests\n// console.log = (...args: any[]) => {\n// if (args[0]?.includes?.('🧪') || args[0]?.includes?.('Test')) {\n// originalConsoleLog(...args);\n// }\n// };\n\n// console.error = (...args: any[]) => {\n// if (args[0]?.includes?.('Test') || args[0]?.includes?.('Error')) {\n// originalConsoleError(...args);\n// }\n// };\n\n// console.warn = (...args: any[]) => {\n// if (args[0]?.includes?.('Test') || args[0]?.includes?.('Warning')) {\n// originalConsoleWarn(...args);\n// }\n// };\n\n// Setup test timeout\nconst TEST_TIMEOUT = 30000; // 30 seconds\n\n// Export test configuration\nexport const testConfig = {\n timeout: TEST_TIMEOUT,\n setupComplete: true,\n};\n\nconsole.log(\"✅ Test environment setup complete!\");",[],[429,474],[429],{"_108":483,"_100":484,"_152":485,"_154":-5,"_155":139,"_156":486,"_158":159,"_110":487,"_105":31,"_161":385,"_163":488,"_164":27,"_165":-5,"_166":489,"_103":490},"5fcd6a16-4b01-11f0-9a42-76b3cceeab13","IMPLEMENTATION-SUMMARY.md","5fcd6ae8-4b01-11f0-9a42-76b3cceeab13",716,["D",1750112972278],"# NextSteps Feature Implementation Summary\n\n## Overview\n\nSuccessfully implemented the NextSteps feature for dynamic interaction in the Anthropic Streaming Chat with MCP application. This feature allows MCP servers to propose follow-up actions that can be automatically executed after a countdown or manually selected by users.\n\n## Implementation Details\n\n### 1. Type Definitions (`shared/types.ts`)\n- Added `NextStepProposal` interface for individual action proposals\n- Added `NextStepsOutput` interface for the complete NextSteps data structure\n- Integrated with existing MCP tool result format\n\n### 2. NextSteps Component (`frontend/components/NextSteps.tsx`)\n- **Visual Design**: Pill-shaped buttons with progress indicators\n- **Auto-Execution**: Countdown timer with automatic proposal execution\n- **Manual Selection**: Click-to-execute for manual proposals\n- **User Interaction**: Hover/click cancels auto-execution\n- **Progress Indicators**: \n - Animated progress bars for countdown (blue)\n - Static progress bars for priority indication (gray)\n- **Mobile Responsive**: Stacks vertically on small screens\n\n### 3. Message Component Integration (`frontend/components/Message.tsx`)\n- Enhanced `mcp_tool_result` handling to detect NextSteps output\n- Renders NextSteps component when `output.nextSteps` is found\n- Maintains existing HTML output functionality\n- Passes message sending callback for proposal execution\n\n### 4. App Configuration (`frontend/components/App.tsx`)\n- Added `autoExecuteNextSteps` boolean to AppConfig interface\n- Integrated with localStorage persistence\n- Defaults to `true` (enabled)\n\n### 5. Settings Integration (`frontend/components/Settings.tsx`)\n- Added toggle switch for NextSteps auto-execution\n- Clear description of functionality\n- Persisted in localStorage as `auto_execute_next_steps`\n\n### 6. StreamingChat Integration (`frontend/components/StreamingChat.tsx`)\n- Modified `fireSend` function to accept optional string parameter\n- Passes NextSteps callbacks to MessageComponent\n- Supports NextSteps execution during live streaming\n- Maintains existing input handling for manual messages\n\n### 7. Styling (`frontend/style.css`)\n- Comprehensive CSS for NextSteps components\n- Progress bar animations and transitions\n- Mobile-responsive design\n- Consistent with existing design system\n\n## Key Features Implemented\n\n### ✅ Custom MCP Tool Result Format\n- NextSteps detected via `output.nextSteps` in MCP tool results\n- JSON parsing with graceful error handling\n- Maintains compatibility with existing HTML output\n\n### ✅ Global Setting with Per-Result Override\n- Global toggle in settings (default: enabled)\n- Per-result `type` field overrides global setting\n- User interaction cancels auto-execution\n\n### ✅ Visual Priority Indication\n- Progress bars show countdown for auto-execution\n- Static progress bars indicate priority for manual proposals\n- Color coding: blue for countdown, gray for priority\n\n### ✅ Inline Content Blocks\n- Pills appear within assistant messages\n- Integrated with existing message rendering system\n- Maintains message persistence and history\n\n### ✅ User Interaction Cancellation\n- Hover over NextSteps cancels auto-execution\n- Click on any proposal cancels auto-execution\n- Typing in chat input cancels auto-execution\n- Visual feedback when cancelled\n\n## Technical Architecture\n\n### Data Flow\n1. MCP server returns tool result with `output.nextSteps`\n2. Message component detects NextSteps during rendering\n3. NextSteps component manages countdown and user interaction\n4. Proposal execution triggers message sending via callback\n5. New user message added to chat history\n\n### State Management\n- NextSteps component manages local countdown state\n- User interaction state prevents auto-execution\n- Global setting stored in localStorage\n- No additional global state required\n\n### Error Handling\n- Malformed NextSteps data falls back to raw display\n- JSON parsing errors logged to console\n- Missing required fields handled gracefully\n- Client continues normal operation on errors\n\n## Files Modified/Created\n\n### New Files\n- `/frontend/components/NextSteps.tsx` - Main NextSteps component\n- `/NextSteps-README.md` - Feature documentation and MCP server spec\n- `/NextSteps-Examples.md` - Implementation examples for MCP servers\n- `/IMPLEMENTATION-SUMMARY.md` - This summary document\n\n### Modified Files\n- `/shared/types.ts` - Added NextSteps type definitions\n- `/frontend/components/App.tsx` - Added autoExecuteNextSteps config\n- `/frontend/components/Message.tsx` - Added NextSteps detection and rendering\n- `/frontend/components/Settings.tsx` - Added auto-execution toggle\n- `/frontend/components/StreamingChat.tsx` - Modified fireSend for NextSteps\n- `/frontend/style.css` - Added NextSteps styling\n- `/README.md` - Updated feature list and documentation\n\n## Testing Recommendations\n\n### Manual Testing\n1. Create MCP tool that returns NextSteps with `type: \"auto\"`\n2. Verify countdown timer appears and executes automatically\n3. Test user interaction cancellation (hover, click)\n4. Create NextSteps with `type: \"manual\"` and verify manual execution\n5. Test priority display for manual proposals\n6. Verify global setting toggle in Settings\n7. Test mobile responsiveness\n\n### Example Test Data\n```json\n{\n \"output\": {\n \"nextSteps\": {\n \"type\": \"auto\",\n \"countdown\": 5,\n \"proposals\": [\n {\n \"id\": \"test_action\",\n \"title\": \"Test Action\",\n \"description\": \"This is a test NextSteps proposal\",\n \"action\": {\n \"type\": \"send_message\",\n \"content\": \"NextSteps test completed successfully!\"\n }\n }\n ]\n }\n }\n}\n```\n\n## Future Enhancements\n\n### Planned Features\n- **Additional Action Types**: File downloads, API calls, direct tool execution\n- **Conditional Logic**: Proposals based on user context or chat history\n- **Scheduling**: Delayed execution beyond immediate countdown\n- **Branching Workflows**: Multiple workflow paths with decision points\n- **Templates**: Reusable NextSteps patterns for common use cases\n\n### Potential Improvements\n- **Visual Enhancements**: More sophisticated progress indicators\n- **Sound Notifications**: Audio cues for countdown completion\n- **Keyboard Navigation**: Arrow keys to select proposals\n- **Batch Operations**: Multiple proposals executed in sequence\n- **History Integration**: Ability to retry/branch from previous NextSteps\n\n## Compliance with Requirements\n\n### ✅ Custom MCP Tool Result Format\nImplemented as `output.nextSteps` field in MCP tool results, similar to existing HTML renderer pattern.\n\n### ✅ Global Setting + Per-Result Control\nGlobal toggle in settings with per-result `type` override.

These proposals can be automatically executed after a countdown or manually selected by the user, enabling fluid conversational workflows and guided user experiences.\n\n## User Experience\n\n### Visual Design\n- **Inline Pills**: NextSteps appear as pill-shaped buttons within assistant messages\n- **Progress Indicators**: Visual progress bars show countdown timers (auto) or priority levels (manual)\n- **Countdown Display**: Numeric countdown badge shows remaining seconds for auto-execution\n- **Cancellation**: User interaction (hover, click, typing) cancels auto-execution\n\n### Interaction Modes\n1. **Auto Execution**: Proposals with `type: \"auto\"` automatically execute after countdown\n2. **Manual Selection**: Proposals with `type: \"manual\"` require user click to execute\n3. **Priority Display**: Manual proposals show static progress bars indicating relative priority\n\n### Global Settings\n- **Auto-Execution Toggle**: Users can globally enable/disable auto-execution in settings\n- **Per-Result Override**: Individual NextSteps can specify \"auto\" or \"manual\" regardless of global setting\n- **Cancellation**: Any user interaction cancels pending auto-execution\n\n## MCP Server Implementation Spec\n\n### Response Format\n\nMCP servers should return NextSteps data in their tool result's `output.nextSteps` field:\n\n```json\n{\n \"content\": [\n {\n \"type\": \"text\", \n \"text\": \"{\\\"output\\\": {\\\"nextSteps\\\": {...}}}\"\n }\n ]\n}\n```\n\n### NextSteps Schema\n\n```typescript\ninterface NextStepsOutput {\n nextSteps: {\n type: \"auto\" | \"manual\"; // Execution mode\n priority?: number; // 0-100, higher = more priority\n countdown?: number; // seconds for auto execution\n proposals: NextStepProposal[]; // Array of action proposals\n };\n}\n\ninterface NextStepProposal {\n id: string; // Unique identifier\n title: string; // Display name (required)\n description?: string; // Optional tooltip/subtitle\n action: {\n type: \"send_message\"; // Currently only message sending supported\n content: string; // Message content to send\n };\n}\n```\n\n### Implementation Examples\n\n#### Basic Auto-Execution Example\n```json\n{\n \"output\": {\n \"nextSteps\": {\n \"type\": \"auto\",\n \"countdown\": 5,\n \"proposals\": [\n {\n \"id\": \"continue_analysis\",\n \"title\": \"Continue Analysis\",\n \"description\": \"Analyze the next data segment\",\n \"action\": {\n \"type\": \"send_message\",\n \"content\": \"Please analyze the next segment of data using the same methodology.\"\n }\n }\n ]\n }\n }\n}\n```\n\n#### Multiple Manual Proposals with Priority\n```json\n{\n \"output\": {\n \"nextSteps\": {\n \"type\": \"manual\",\n \"priority\": 75,\n \"proposals\": [\n {\n \"id\": \"save_results\",\n \"title\": \"Save Results\",\n \"description\": \"Save current analysis to file\",\n \"action\": {\n \"type\": \"send_message\",\n \"content\": \"Please save these results to a file named 'analysis_results.json'\"\n }\n },\n {\n \"id\": \"export_chart\",\n \"title\": \"Export Chart\", \n \"description\": \"Generate visualization\",\n \"action\": {\n \"type\": \"send_message\",\n \"content\": \"Create a chart visualization of these results\"\n }\n },\n {\n \"id\": \"email_summary\",\n \"title\": \"Email Summary\",\n \"description\": \"Send summary via email\",\n \"action\": {\n \"type\": \"send_message\", \n \"content\": \"Compose an email summary of this analysis for stakeholders\"\n }\n }\n ]\n }\n }\n}\n```\n\n#### Conditional Auto-Execution\n```json\n{\n \"output\": {\n \"nextSteps\": {\n \"type\": \"auto\",\n \"countdown\": 10,\n \"priority\": 90,\n \"proposals\": [\n {\n \"id\": \"retry_failed\",\n \"title\": \"Retry Failed Operations\",\n \"description\": \"Automatically retry the 3 failed operations\",\n \"action\": {\n \"type\": \"send_message\",\n \"content\": \"Retry the failed operations: upload_file, process_data, send_notification\"\n }\n }\n ]\n }\n }\n}\n```\n\n### Best Practices for MCP Servers\n\n#### When to Use NextSteps\n- **Multi-step workflows**: Guide users through complex processes\n- **Error recovery**: Offer automatic retry or alternative approaches \n- **Data processing**: Suggest next analysis steps or data transformations\n- **File operations**: Propose saving, exporting, or sharing results\n- **Iterative tasks**: Continue processing additional data segments\n\n#### Choosing Execution Type\n- **Use `\"auto\"`** for:\n - Obvious next steps in a workflow\n - Error recovery actions\n - Continuing interrupted processes\n - Time-sensitive operations\n- **Use `\"manual\"`** for:\n - Destructive operations (delete, overwrite)\n - User preference decisions\n - Multiple valid alternatives\n - Final confirmation steps\n\n#### Setting Appropriate Timeouts\n- **Short (3-5s)**: Obvious continuations, error retries\n- **Medium (5-10s)**: Workflow steps, data processing\n- **Long (10-15s)**: Complex operations, user review time\n- **No timeout**: Use manual mode instead\n\n#### Priority Guidelines\n- **90-100**: Critical/urgent actions\n- **70-89**: Important workflow steps \n- **50-69**: Helpful suggestions\n- **30-49**: Optional enhancements\n- **10-29**: Nice-to-have actions\n\n### Error Handling\n\nIf NextSteps data is malformed, the client will:\n1. Log a warning to console\n2. Fall back to displaying the raw tool result\n3. Continue normal operation\n\nServers should validate their NextSteps output to ensure:\n- Required fields are present\n- IDs are unique within the proposal set\n- Countdown values are reasonable (1-60 seconds)\n- Priority values are within 0-100 range\n\n### Integration with Existing Tools\n\nNextSteps works alongside existing MCP tool capabilities:\n- **HTML Output**: Can be combined with `output.html` for rich displays\n- **File Operations**: Suggest follow-up actions after file creation/modification\n- **API Calls**: Propose next API operations or data processing steps\n- **Database Operations**: Suggest queries, updates, or analysis steps\n\n### Client Implementation Notes\n\nThe NextSteps feature is implemented in the chat client with:\n- Global auto-execution setting in user preferences\n- Per-message override capability\n- User interaction cancellation (hover, click, typing)\n- Visual progress indicators and countdown timers\n- Persistent storage of user preferences\n- Mobile-responsive pill-based UI\n\n### Future Enhancements\n\nPlanned future capabilities:\n- **Action Types**: Support for file downloads, API calls, tool execution\n- **Conditional Logic**: Proposals based on user context or previous actions\n- **Scheduling**: Delayed execution beyond immediate countdown\n- **Branching**: Multiple workflow paths with decision points\n- **Templates**: Reusable NextSteps patterns for common workflows\n\n## Testing Your Implementation\n\n### Manual Testing\n1. Create a tool that returns NextSteps in the specified format\n2. Test both auto and manual execution modes\n3. Verify countdown timers work correctly\n4. Test user cancellation by interacting during countdown\n5. Verify priority display for manual proposals\n\n### Example Test Tool\n```python\ndef create_test_nextsteps():\n return {\n \"output\": {\n \"nextSteps\": {\n \"type\": \"auto\",\n \"countdown\": 5,\n \"proposals\": [\n {\n \"id\": \"test_action\",\n \"title\": \"Test Action\",\n \"description\": \"This is a test NextSteps proposal\",\n \"action\": {\n \"type\": \"send_message\",\n \"content\": \"NextSteps test completed successfully!\"\n }\n }\n ]\n }\n }\n }\n```\n\n### Validation Checklist\n- [ ] NextSteps object structure matches schema\n- [ ] All required fields are present\n- [ ] Proposal IDs are unique\n- [ ] Countdown values are reasonable (1-60s)\n- [ ] Priority values are 0-100\n- [ ] Action content is meaningful\n- [ ] Titles are concise and descriptive\n- [ ] Descriptions provide helpful context\n\n## Support and Feedback\n\nFor questions about implementing NextSteps in your MCP server:\n- Review the examples in this documentation\n- Test with the provided validation checklist\n- Check browser console for any parsing errors\n- Ensure JSON structure exactly matches the schema\n\nThe NextSteps feature enhances user experience by providing intelligent workflow guidance while maintaining user control and preventing unwanted automatic actions.",[],[502],{"_108":510,"_100":465,"_152":511,"_154":-5,"_155":139,"_156":512,"_158":159,"_110":513,"_105":514,"_161":385,"_163":515,"_164":27,"_165":-5,"_166":516,"_103":517},"7de252be-4dd1-11f0-aaaa-76b3cceeab13","2bc4d286-3cdd-11f0-9e50-9e149126039e",938,["D",1750422260388],47,"# Anthropic Streaming Chat with MCP\n\nA mobile-optimized single page chat application that uses the Anthropic Messages API with **real-time streaming** and MCP (Model Context Protocol) server support, featuring **centralized client management** and **performance optimizations**.\n\nSource: https://www.val.town/x/c15r/Chat \n\nLive server: https://chat.parc.land\n\nBundles Contextual MCP server by default: https://contextual.parc.land/mcp\n\n## 🚀 Key Features\n\n- **🚀 Real-time streaming responses** -

It supports multiple rendering modes based on file type and provides a rich viewing experience with syntax highlighting powered by CodeMirror.\n\n## Features\n\n- **🎨 Syntax Highlighting** - Powered by CodeMirror with support for JavaScript, HTML, CSS, JSON, Markdown, Python, XML, and more\n- **📱 Fullscreen Mode** - Toggle fullscreen for better viewing of large files\n- **🔄 Smart Caching** - Caches fetched content for 5 minutes to improve performance\n- **🔁 Retry Mechanism** - Automatic retry functionality when resource fetching fails\n- **📋 Metadata Display** - Shows file type, content type, and source server information\n- **🎯 Adaptive Rendering** - Chooses optimal rendering mode based on file type and hints\n\n## Usage\n\nResourceViewer is automatically triggered when MCP tools return responses matching the `FileViewerResult` schema:\n\n```typescript\n// Example MCP tool response that triggers ResourceViewer\n{\n \"output\": {\n \"resourcePointer\": {\n \"sourceKey\": \"path/to/file.js\",\n \"contentType\": \"application/javascript\", \n \"fileType\": \"javascript\",\n \"renderHint\": {\n \"preferredRenderer\": \"code\",\n \"syntaxHighlight\": true,\n \"lineNumbers\": true\n }\n },\n \"sourceKey\": \"path/to/file.js\",\n \"fileType\": \"javascript\"\n }\n}\n```\n\n## Schema Reference\n\n### FileViewerResult\n\nThe main response type that triggers ResourceViewer:\n\n```typescript\ntype FileViewerResult = \n | { output: FileViewerResponse }\n | { error: string; output: null };\n```\n\n### FileViewerResponse\n\n```typescript\ninterface FileViewerResponse {\n resourcePointer: ResourcePointer;\n sourceKey: string;\n fileType: ResourcePointer['fileType'];\n}\n```\n\n### ResourcePointer\n\n```typescript\ninterface ResourcePointer {\n sourceKey: string; // Path/key to the resource\n contentType: string; // MIME type (e.g., \"application/javascript\")\n fileType: FileType; // Detected file type for syntax highlighting\n renderHint: RenderHints; // Rendering preferences\n}\n```\n\n### RenderHints\n\n```typescript\ninterface RenderHints {\n preferredRenderer: 'native' | 'code' | 'text';\n syntaxHighlight: boolean;\n lineNumbers: boolean;\n}\n```\n\n### Supported File Types\n\n- `javascript` - JavaScript files (.js, .jsx, .ts, .tsx)\n- `html` - HTML files (.html, .htm)\n- `css` - CSS files (.css, .scss, .sass)\n- `json` - JSON files (.json)\n- `markdown` - Markdown files (.md, .mdx)\n- `python` - Python files (.py)\n- `xml` - XML files (.xml, .svg)\n- `text` - Plain text files\n- `unknown` - Fallback for unrecognized types\n\n## Rendering Modes\n\n### Code Mode (`preferredRenderer: 'code'`)\n- Uses CodeMirror editor with syntax highlighting\n- Supports line numbers when `lineNumbers: true`\n- Best for source code files\n\n### Native Mode (`preferredRenderer: 'native'`)\n- Renders HTML/XML content in an iframe\n- Provides native browser rendering\n- Best for HTML documents and SVG files\n\n### Text Mode (`preferredRenderer: 'text'`)\n- Plain text display with optional line numbers\n- Best for configuration files and plain text\n\n## Integration\n\n### Server Name Resolution\n\nResourceViewer automatically resolves the MCP server name by matching the `tool_use_id` from `mcp_tool_result` blocks with corresponding `mcp_tool_use` blocks:\n\n```typescript\n// In Message.tsx\nconst toolUseBlock = findToolUseBlock(blocks, blk.tool_use_id);\nconst serverName = toolUseBlock?.server_name;\n```\n\n### Resource Fetching\n\nResources are fetched using the MCP client's `readResource()` method:\n\n```typescript\nconst client = mcpClients.find(client => \n client.serverInfo?.name === serverName\n);\nconst content = await client.readResource(sourceKey);\n```\n\n### Caching Strategy\n\n- Resources are cached in component state for 5 minutes\n- Cache key format: `${serverName}_${sourceKey}`\n- Cache is cleared on retry to force fresh fetch\n\n## Error Handling\n\nResourceViewer provides comprehensive error handling:\n\n1. **Parse Errors** - Invalid FileViewerResult schema\n2. **Server Not Found** - MCP server unavailable\n3. **Resource Not Found** - Resource doesn't exist\n4. **Network Errors** - Connection issues\n\nError states show:\n- Clear error message\n- Retry button\n- Expandable metadata for debugging\n\n## Styling\n\nResourceViewer uses CSS classes for styling:\n\n- `.resource-viewer` - Main container\n- `.resource-viewer-header` - Header with metadata and controls\n- `.resource-viewer-content` - Content area\n- `.resource-viewer-error` - Error state styling\n- `.resource-viewer.fullscreen` - Fullscreen mode\n\n## Examples\n\n### JavaScript File Display\n\n```json\n{\n \"output\": {\n \"resourcePointer\": {\n \"sourceKey\": \"src/components/App.tsx\",\n \"contentType\": \"application/typescript\",\n \"fileType\": \"javascript\",\n \"renderHint\": {\n \"preferredRenderer\": \"code\",\n \"syntaxHighlight\": true,\n \"lineNumbers\": true\n }\n },\n \"sourceKey\": \"src/components/App.tsx\",\n \"fileType\": \"javascript\"\n }\n}\n```\n\n### HTML Document Display\n\n```json\n{\n \"output\": {\n \"resourcePointer\": {\n \"sourceKey\": \"public/index.html\",\n \"contentType\": \"text/html\",\n \"fileType\": \"html\", \n \"renderHint\": {\n \"preferredRenderer\": \"native\",\n \"syntaxHighlight\": false,\n \"lineNumbers\": false\n }\n },\n \"sourceKey\": \"public/index.html\",\n \"fileType\": \"html\"\n }\n}\n```\n\n### Configuration File Display\n\n```json\n{\n \"output\": {\n \"resourcePointer\": {\n \"sourceKey\": \"package.json\",\n \"contentType\": \"application/json\",\n \"fileType\": \"json\",\n \"renderHint\": {\n \"preferredRenderer\": \"code\",\n \"syntaxHighlight\": true,\n \"lineNumbers\": true\n }\n },\n \"sourceKey\": \"package.json\", \n \"fileType\": \"json\"\n }\n}\n```\n\n## Implementation Notes\n\n- ResourceViewer is integrated into the Message component's `renderAnthropicBlocks()` function\n- Detection happens in the `mcp_tool_result` case after NextSteps and before HTML detection\n- CodeMirror extensions are loaded dynamically based on file type\n- Fullscreen mode uses fixed positioning with high z-index\n- Mobile-responsive design with touch-friendly controls\n\n### Performance Optimizations\n\n- **Memoized MCP Client Resolution** - Client lookup is memoized to prevent unnecessary re-renders\n- **Stable Reference Management** - MCP clients array is memoized in the parent hook to prevent reload loops\n- **Simplified Dependency Chains** - Reduced nested useCallback dependencies to minimize effect re-executions\n- **Optimized useEffect Dependencies** - Removed function dependencies that caused infinite reload loops\n\n## Dependencies\n\n- **CodeMirror 6** - Syntax highlighting and code editing\n- **React 18** - Component framework\n- **MCP Client** - Resource fetching from MCP servers\n\n## Future Enhancements\n\n- **Binary File Support** - Display images, PDFs, etc.\n- **Diff Viewer** - Compare file versions\n- **Search/Find** - In-file search functionality\n- **Download Support** - Save resources locally\n- **Collaborative Editing** - Real-time editing capabilities",[],[520],{"_108":528,"_100":529,"_152":530,"_154":-5,"_155":139,"_156":531,"_158":159,"_110":532,"_105":31,"_161":385,"_163":533,"_164":27,"_165":-5,"_166":534,"_103":535},"fefe5778-4ce4-11f0-a2f7-76b3cceeab13","TESTING.md","fefe584a-4ce4-11f0-a2f7-76b3cceeab13",837,["D",1750320686276],"# Testing Guide\n\nThis document provides comprehensive guidance for testing the Anthropic Streaming Chat MCP application.\n\n## Overview\n\nThe application uses **Deno** as the test runner with **React Testing Library** for component testing. Tests are written in TypeScript and follow modern testing practices with proper mocking and isolation.\n\n## Quick Start\n\n```bash\n# Install dependencies (if using npm scripts)\nnpm install\n\n# Run all tests\nnpm test\n\n# Run tests in watch mode\nnpm run test:watch\n\n# Run with coverage\nnpm run test:coverage\n```\n\n## Test Architecture\n\n### Testing Stack\n\n- **Test Runner**: Deno Test\n- **Component Testing**: React Testing Library\n- **Assertions**: Deno Standard Library Assert\n- **Mocking**: Custom utilities + built-in Deno mocks\n- **Coverage**: Deno built-in coverage tools\n\n### Project Structure\n\n```\ntest/\n├── components/ # Component-specific tests\n│ └── Message.test.tsx # Message component tests\n├── utils/ # Testing utilities\n│ └── test-helpers.ts # Mock factories and helpers\n├── setup.ts # Global test configuration\n└── README.md # Test-specific documentation\n```\n\n## Writing Tests\n\n### Component Testing Pattern\n\n```typescript\n/** @jsxImportSource https://esm.sh/react@18.2.0 */\nimport { assertEquals, assertExists } from \"https://deno.land/std@0.208.0/assert/mod.ts\";\nimport { render, cleanup } from \"https://esm.sh/@testing-library/react@14.0.0?deps=react@18.2.0,react-dom@18.2.0\";\nimport React from \"https://esm.sh/react@18.2.0\";\nimport { createMockMessage } from \"../utils/test-helpers.ts\";\nimport ComponentToTest from \"../../frontend/components/ComponentToTest.tsx\";\n\nDeno.test(\"ComponentToTest - Feature Category\", async (t) => {\n await t.step(\"should render correctly with basic props\", () => {\n const mockData = createMockMessage();\n \n const { container } = render(\n \n );\n \n const element = container.querySelector('.expected-class');\n assertExists(element, \"Component should render expected element\");\n });\n \n // Always cleanup after component tests\n cleanup();\n});\n```\n\n### Test Helpers Usage\n\nThe `test-helpers.ts` file provides utilities for creating consistent mock data:\n\n```typescript\nimport { \n createMockMessage, \n createMockMCPServer,\n createMockCallback,\n createMockAnthropicBlocks \n} from \"../utils/test-helpers.ts\";\n\n// Create mock message with defaults\nconst message = createMockMessage();\n\n// Create mock message with overrides\nconst assistantMessage = createMockMessage({\n role: \"assistant\",\n content: \"Custom content\"\n});\n\n// Create mock callback that tracks calls\nconst mockCallback = createMockCallback();\n// Later: assertEquals(mockCallback.calls.length, 1);\n\n// Create mock Anthropic blocks for streaming tests\nconst blocks = createMockAnthropicBlocks([\n { type: \"text\", text: \"Hello\" },\n { type: \"code\", text: \"console.log('test')\", language: \"javascript\" }\n]);\n```\n\n### Testing Different Message Types\n\n#### Text Messages\n\n```typescript\nawait t.step(\"should render text message\", () => {\n const message = createMockMessage({\n content: \"Simple text message\"\n });\n \n const { container } = render();\n assertStringIncludes(container.innerHTML, \"Simple text message\");\n});\n```\n\n#### Block Content (Streaming)\n\n```typescript\nawait t.step(\"should render streaming blocks\", () => {\n const message = createMockMessage({\n content: [\n { type: \"text\", text: \"Streaming text\", _streaming: true },\n { type: \"code\", text: \"const x = 1;\", language: \"javascript\" }\n ]\n });\n \n const { container } = render();\n \n // Check for streaming cursor\n const cursor = container.querySelector('.streaming-cursor');\n assertExists(cursor, \"Should show streaming cursor\");\n \n // Check for code block\n const codeBlock = container.querySelector('.anthropic-code-block');\n assertExists(codeBlock, \"Should render code block\");\n});\n```\n\n#### MCP Tool Results\n\n```typescript\nawait t.step(\"should render MCP tool results\", () => {\n const message = createMockMessage({\n content: [\n createMockMCPToolUse({ name: \"file_reader\" }),\n createMockMCPToolResult({ \n content: [{ text: JSON.stringify({ output: \"File content\" }) }]\n })\n ]\n });\n \n const { container } = render();\n \n const toolDetails = container.querySelector('.mcp-details');\n assertExists(toolDetails, \"Should render MCP tool details\");\n});\n```\n\n### Testing Interactive Features\n\n#### Button Actions\n\n```typescript\nawait t.step(\"should handle button clicks\", () => {\n const mockOnDelete = createMockCallback();\n const message = createMockMessage();\n \n const { container } = render(\n \n );\n \n const deleteButton = container.querySelector('.delete-btn');\n assertExists(deleteButton, \"Delete button should exist\");\n \n // Simulate click (note: actual click simulation requires more setup)\n // This tests that the button is rendered correctly\n});\n```\n\n#### Conditional Rendering\n\n```typescript\nawait t.step(\"should conditionally render retry button\", () => {\n const message = createMockMessage();\n const mockOnRetry = createMockCallback();\n \n // Test with canRetry = true\n const { container: containerWithRetry } = render(\n \n );\n \n assertExists(\n containerWithRetry.querySelector('.retry-btn'),\n \"Should show retry button when canRetry is true\"\n );\n \n // Test with canRetry = false\n const { container: containerNoRetry } = render(\n \n );\n \n assertEquals(\n containerNoRetry.querySelector('.retry-btn'),\n null,\n \"Should not show retry button when canRetry is false\"\n );\n});\n```\n\n## Test Categories\n\n### 1. Unit Tests\n- Individual component functionality\n- Utility function behavior\n- Type validation\n\n### 2. Integration Tests\n- Component interaction\n- Data flow between components\n- MCP client integration\n\n### 3. Rendering Tests\n- Component output verification\n- Conditional rendering\n- Props handling\n\n### 4. Interaction Tests\n- Button clicks and callbacks\n- Form submissions\n- User input handling\n\n## Mocking Strategy\n\n### Global Mocks (setup.ts)\n\n```typescript\n// DOM APIs\nglobalThis.localStorage = mockLocalStorage;\nglobalThis.fetch = mockFetch;\nglobalThis.crypto.randomUUID = mockUUID;\n\n// Browser APIs\nnavigator.clipboard = mockClipboard;\nglobalThis.alert = mockAlert;\n```\n\n### Component-Specific Mocks\n\n```typescript\n// Mock MCP clients\nconst mockMCPClients = [];\n\n// Mock callbacks\nconst mockOnSendMessage = createMockCallback();\nconst mockOnDelete = createMockCallback();\n```\n\n## Coverage and Quality\n\n### Running Coverage\n\n```bash\n# Generate coverage data\nnpm run test:coverage\n\n# Generate HTML report\nnpm run test:coverage-report\n\n# View report\nopen coverage/html/index.html\n```\n\n### Coverage Goals\n\n- **Components**: >90% line coverage\n- **Utilities**: >95% line coverage\n- **Critical paths**: 100% coverage\n\n### Quality Metrics\n\n- All tests should be deterministic\n- No flaky tests\n- Fast execution (<30s total)\n- Clear, descriptive test names\n\n## Best Practices\n\n### Test Organization\n\n```typescript\nDeno.test(\"ComponentName - Feature Category\", async (t) => {\n await t.step(\"should handle normal case\", () => {\n // Test implementation\n });\n \n await t.step(\"should handle edge case\", () => {\n // Test implementation\n });\n \n await t.step(\"should handle error case\", () => {\n // Test implementation\n });\n \n cleanup(); // Always cleanup after component tests\n});\n```\n\n### Naming Conventions\n\n- **Test files**: `ComponentName.test.tsx`\n- **Test suites**: `\"ComponentName - Feature Category\"`\n- **Test cases**: `\"should [expected behavior]\"`\n- **Mock functions**: `mock[FunctionName]`\n\n### Assertion Guidelines\n\n```typescript\n// Good: Specific assertions\nassertExists(element, \"Button should exist\");\nassertEquals(calls.length, 1, \"Callback should be called once\");\nassertStringIncludes(html, \"expected text\");\n\n// Avoid: Generic assertions\nassert(element); // Not descriptive\nassertEquals(result, true); // Not specific\n```\n\n### Mock Data Consistency\n\n```typescript\n// Good: Use test helpers\nconst message = createMockMessage({ role: \"assistant\" });\n\n// Avoid: Inline mock data\nconst message = { \n id: \"123\", \n role: \"assistant\", \n content: \"test\", \n timestamp: 1234567890 \n};\n```\n\n## Debugging Tests\n\n### Common Issues\n\n1. **Import Errors**: Ensure React version pinning in imports\n2. **Component Not Rendering**: Check required props\n3. **Async Issues**: Use proper async/await patterns\n4. **Mock Problems**: Verify setup.ts configuration\n\n### Debug Techniques\n\n```typescript\n// Log component output\nconst { container } = render();\nconsole.log(\"HTML:\", container.innerHTML);\n\n// Check mock calls\nconsole.log(\"Mock calls:\", mockCallback.calls);\n\n// Verify element selection\nconst element = container.querySelector('.target');\nconsole.log(\"Element found:\", !!element);\n```\n\n### Test Isolation\n\n- Each test should be independent\n- Use `cleanup()` after component tests\n- Reset mocks between tests if needed\n- Avoid shared state between tests\n\n## Continuous Integration\n\n### Pre-commit Hooks\n\n```bash\n# Run tests before commit\nnpm test\n\n# Run linting\ndeno lint\n\n# Run formatting\ndeno fmt --check\n```\n\n### CI Pipeline\n\n```yaml\n# Example GitHub Actions workflow\n- name: Run Tests\n run: |\n deno test --allow-all test/\n deno coverage coverage --html\n```\n\n## Adding New Tests\n\n### Checklist\n\n- [ ] Create test file in appropriate directory\n- [ ] Follow naming conventions\n- [ ] Import required testing utilities\n- [ ] Use test helpers for mock data\n- [ ] Include cleanup calls\n- [ ] Test happy path and edge cases\n- [ ] Add descriptive assertions\n- [ ] Update documentation if needed\n\n### Template\n\n```typescript\n/** @jsxImportSource https://esm.sh/react@18.2.0 */\nimport { assertEquals, assertExists } from \"https://deno.land/std@0.208.0/assert/mod.ts\";\nimport { render, cleanup } from \"https://esm.sh/@testing-library/react@14.0.0?deps=react@18.2.0,react-dom@18.2.0\";\nimport React from \"https://esm.sh/react@18.2.0\";\nimport { createMockMessage } from \"../utils/test-helpers.ts\";\nimport NewComponent from \"../../frontend/components/NewComponent.tsx\";\n\nDeno.test(\"NewComponent - Basic Functionality\", async (t) => {\n await t.step(\"should render with default props\", () => {\n // Test implementation\n });\n \n await t.step(\"should handle prop changes\", () => {\n // Test implementation\n });\n \n cleanup();\n});\n```\n\n## Resources\n\n- [Deno Testing Documentation](https://deno.land/manual/testing)\n- [React Testing Library Documentation](https://testing-library.com/docs/react-testing-library/intro/)\n- [Deno Standard Library Assert](https://deno.land/std/assert)\n- [ESM.sh for React Dependencies](https://esm.sh/)\n\n## Contributing\n\nWhen adding tests:\n\n1.
