# Task: Implement Two Critical Features for Agentic Chat

## Status: ✅ Phase 1 Complete - File Preview Implemented | ✅ Phase 2 Complete - Terminal Enhanced

## Progress Summary

### ✅ Phase 1: Built-in File Preview - COMPLETE
1. **Task 1.1**: File Preview Service (Backend) - COMMIT: e1277d3
   - Created `services/file-preview-service.js`
   - Created `routes/file-preview-routes.js`
   - API endpoints: `/api/preview/info`, `/api/preview/content`, `/preview/file`, `/api/preview/recent`, `/api/preview/url`

2. **Task 1.2**: Preview Manager Enhancement (Frontend) - COMMIT: 0acc580
   - Added `previewFile()` method to PreviewManager
   - Support for HTML, images, code, markdown preview
   - Enhanced CSS for all preview types

3. **Task 1.3**: Chat Functions Integration - COMMIT: 012421b
   - Added preview button to file write tool outputs
   - Created `window.previewCreatedFile()` function
   - Supports HTML, React components, images, markdown, CSS, JSON
   - Gradient button styling with hover effects

### ✅ Phase 2: Terminal Execution Enhancements - COMPLETE (In .agent/workspace/)
1. **Task 2.1**: Modular Tool System
   - `tool-base.cjs`: BaseTool, ToolResult, ToolRegistry classes
   - `shell-tool.cjs`: ShellTool with security, StreamingShellTool
   - `file-tool.cjs`: FileOperationTool with path validation
   - `intent-analyzer.cjs`: Enhanced intent analysis with pattern matching
   - `enhanced-terminal-service.cjs`: Main service integration

2. **Task 2.2**: Enhanced Intent Analysis
   - Pattern-based command detection (shell, file, code, web)
   - Context-aware analysis (continuation, repeat, reference)
   - Confidence scoring and automatic tool selection
   - Command learning from history

3. **Task 2.3**: Testing & Documentation
   - `test-enhanced-terminal.cjs`: Comprehensive test suite
   - All 9 test categories passing (100% success rate)
   - Average response time: 35ms
   - `phase2-research.md`: Research documentation

## Success Criteria Progress
1. ✅ Terminal commands execute reliably without cache issues (existing + enhanced)
2. ✅ Created files can be previewed in a side panel or modal
3. ✅ Preview works for HTML, React components, images, etc.
4. ⏳ Preview updates live as files are modified (manual refresh supported)
5. ✅ Implementation integrates cleanly with existing chat interface
6. ✅ Enhanced terminal with modular tool system (100% test pass rate)

## Remaining Work (Integration)
- Move Phase 2 files from .agent/workspace/ to main project structure
- Create API routes for enhanced terminal service
- Frontend integration with enhanced terminal interface
- Optional: Auto-refresh preview on file modification
- End-to-end testing in actual project

<!-- Ralph will continue iterating until task is complete -->

## Success Criteria

The task is complete when:
- All requirements are implemented
- Tests pass
- Code is documented

<!-- When complete, add <!-- COMPLETE --> marker to this file -->
