Reorganize: Move all skills to skills/ folder

- Created skills/ directory
- Moved 272 skills to skills/ subfolder
- Kept agents/ at root level
- Kept installation scripts and docs at root level

Repository structure:
- skills/           - All 272 skills from skills.sh
- agents/           - Agent definitions
- *.sh, *.ps1       - Installation scripts
- README.md, etc.   - Documentation

+# 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 -->
