# Agentic Chat Features - Implementation Scratchpad

## Task Overview
Implement two critical features for agentic chat:
1. **Robust Terminal Execution** - Research AGIAgent terminal execution and adapt
2. **Built-in File Preview** - Preview created files (HTML, React, images) in side panel

## Research Findings

### AGIAgent Terminal Execution Analysis
From GitHub research, AGIAgent uses:
- **Python-based CLI** (`agia.py`) with modular architecture in `src/` directory
- **ReAct pattern**: THOUGHT → ACTION → OBSERVATION → THOUGHT loop
- **Tool system**: Modular tools for shell, file operations, web search
- **Multi-agent architecture**: AgentManager for coordinating multiple agents
- **Message routing system** for inter-agent communication
- **Flexible model support**: Anthropic/OpenAI API compatible

Key architectural patterns:
- `src/tools/` - Individual tool implementations
- `src/tools/global_code_index_manager.py` - Code indexing
- `src/tools/message_system.py` - Message routing
- Single-task mode by default (skips task decomposition)

### Current Project Architecture
- `terminal-agent.js` - Frontend terminal intent detection
- `ralph-terminal-service.js` - Backend service using Ralph Orchestrator
- `ralph-terminal-routes.js` - Express API routes
- `preview-manager.js` - Existing preview system for live servers
- Uses **Ralph Orchestrator** for agentic execution

## Current Implementation Status

### Feature 1: Terminal Execution
- ✅ Basic shell command execution via `executeDirect()`
- ✅ Ralph Orchestrator integration for complex tasks
- ✅ Intent analysis (shell command, file operation, web search)
- ✅ Debug logging and telemetry
- ✅ Health check endpoint
- ✅ **NEW: Modular Tool System (Phase 2)**

**Phase 2 Enhancements:**
1. ✅ Modular tool system with BaseTool interface
2. ✅ Tool Registry for managing tools
3. ✅ Enhanced Intent Analyzer with pattern matching
4. ✅ ShellTool with security checks and timeout
5. ✅ FileOperationTool for safe file operations
6. ✅ StreamingShellTool for long-running commands
7. ✅ EnhancedTerminalService integrating all components
8. ✅ Comprehensive test suite (100% pass rate)

**Possible Further Improvements:**
1. Code indexing for smarter operations
2. Message routing system for multi-agent workflows
3. Web search tool integration

### Feature 2: File Preview
- ✅ `preview-manager.js` exists for live server preview
- ✅ Preview panel with iframe rendering
- ✅ `file-preview-service.js` backend for file info and content
- ✅ `file-preview-routes.js` API endpoints
- ✅ Preview Manager enhanced with `previewFile()` method
- ✅ Preview buttons added to file write tool outputs

## Implementation Plan

### Phase 1: Enhanced File Preview (Priority - User Pain Point) ✅ COMPLETE

#### Task 1.1: Create File Preview Service (Backend) ✅
- **File**: `services/file-preview-service.js`
- **API**: `POST /api/preview/file` - Get file content for preview
- **Features**:
  - Detect file type (HTML, images, code, markdown)
  - Read file content with proper encoding
  - Generate preview URL or content
  - Support for React components (transpile if needed)
- **COMMIT**: e1277d3

#### Task 1.2: Enhance Preview Manager (Frontend) ✅
- **File**: `public/claude-ide/preview-manager.js`
- **Features**:
  - `previewFile(filePath, fileType)` method
  - Auto-preview on file creation
  - Support different file types
  - Modal or side panel display
- **COMMIT**: 0acc580

#### Task 1.3: Hook Into Chat Functions ✅
- Detect when AI creates files
- Auto-trigger preview
- Show "Preview" button on file creation messages
- **COMMIT**: 012421b

### Phase 2: Terminal Execution Enhancements ✅ COMPLETE

#### Task 2.1: Modular Tool System ✅
- Created `tool-base.cjs` with BaseTool, ToolResult, ToolRegistry
- Created `shell-tool.cjs` with ShellTool and StreamingShellTool
- Created `file-tool.cjs` with FileOperationTool
- Created `intent-analyzer.cjs` with enhanced intent analysis
- Created `enhanced-terminal-service.cjs` integrating all components

**Key Features:**
- Modular tool abstraction with base interface
- Tool registration and execution with middleware support
- Security checks for dangerous commands
- Timeout and output size limits
- Execution history and statistics
- Command suggestions based on history
- Intent analysis with pattern matching (shell, file, code, web)

#### Task 2.2: Enhanced Intent Analysis ✅
- Pattern-based command detection
- Context-aware analysis (command continuation, repeat, reference)
- Confidence scoring for intent classification
- Automatic tool selection based on intent
- Command learning from history

#### Task 2.3: Testing and Documentation ✅
- Created comprehensive test suite (`test-enhanced-terminal.cjs`)
- All tests passing (100% success rate)
- Test coverage includes:
  - Basic shell commands
  - Intent analysis
  - File operations
  - Command suggestions
  - Multiple command types
  - Service statistics
  - Health checks
  - Execution history
