+# AI Integration Implementation Summary
+
+## Overview
+Successfully implemented AI integration for the DikuMUD client to assist with parsing failures and provide command suggestions. The implementation follows the design outlined in `SLM_DESIGN.md` and provides both CLI and framework for web mode support.
+
+## Completed Features
+
+### 1. `<last_command>` Trigger Variable ✅
+**Files Modified:**
+- `internal/tui/app.go` - Added `lastCommand` field to Model struct
+- `internal/tui/app.go` - Updated command sending to track last command
+- `internal/tui/app.go` - Added substitution logic in trigger processing
+
+**How it works:**
+- Every command sent by the user is stored in `Model.lastCommand`
+- When a trigger fires, any `<last_command>` placeholder in the action is replaced with the actual last command
+- Works alongside normal trigger variable substitution (e.g., `<player>`, `<target>`)
+
+**Example:**
+```
+/trigger "Huh?!" "/ai <last_command>"
+> heall
+Huh?!
+[Trigger: /ai heall]
+```
+
+### 2. AI Configuration Storage ✅
+**Files Modified:**
+- `internal/config/account.go` - Added `AIConfig` struct
+- `internal/config/account.go` - Added `AI` and `AIPrompt` fields to Config
+- `internal/config/account.go` - Added getter/setter methods
+
+**Configuration Stored:**
+- AI Type (openai, ollama)
+- AI URL (endpoint)
+- AI Prompt template
+- API Key (stored securely in password store)
+
+### 3. `/configure-ai` Command ✅
+**Files Modified:**
+- `internal/tui/app.go` - Added `handleConfigureAICommand` function
+
+**Usage:**
+```
+/configure-ai openai https://api.openai.com/v1/chat/completions sk-...
+/configure-ai ollama http://localhost:11434/api/generate
+```
+
+**Features:**
+- Saves configuration to user's config file
+- Supports optional API key parameter
+- Validates required parameters
+
+### 4. `/ai-prompt` Command ✅
+**Files Modified:**
+- `internal/tui/app.go` - Added `handleAIPromptCommand` function
+
+**Usage:**
+```
+/ai-prompt "Custom prompt with {command} placeholder"
+/ai-prompt preset barsoom
+```
+
+**Features:**
+- Custom prompt templates
+- Preset support (Barsoom preset loaded from `data/presets/barsoom.prompt`)
+- Uses `{command}` placeholder for user input
+
+### 5. AI Client Implementation ✅
+**Files Created:**
+- `internal/ai/client.go` - AI client with OpenAI and Ollama support
+- `internal/ai/client_test.go` - Unit tests for AI client
+
+**Supported APIs:**
+- OpenAI (gpt-3.5-turbo)
+- Ollama (llama2 default, configurable)
+
+**Features:**
+- HTTP client with 30-second timeout
+- Proper error handling
+- JSON request/response parsing
+
+### 6. `/ai` Command ✅ (CLI Mode)
+**Files Modified:**
+- `internal/tui/app.go` - Added `handleAICommand` function
+
+**Usage:**
+```
+/ai <last_command>
+/ai how do I heal
+```
+
+**Features:**
+- Sends prompt to configured AI endpoint
+- Displays AI response
+- Automatically sends suggested command to MUD
+- Supports `<last_command>` substitution
+
+**Web Mode:** Marked as TODO - requires browser-side HTTP calls
+
+### 7. `/howto` Command ✅
+**Files Modified:**
+- `internal/tui/app.go` - Added `handleHowtoCommand` function
+
+**Usage:**
+```
+/howto heal myself
+/howto find the marketplace
+```
+
+**Features:**
+- Similar to `/ai` but informational only
+- Does not execute commands
+- Displays response in trigger-match style
+
+## Testing
+
+### Unit Tests ✅
+1. **AI Client Tests** (`internal/ai/client_test.go`)
+   - Client creation
+   - Type validation (openai/ollama)
+   - Unsupported type error handling
+
+2. **Trigger Tests** (`internal/triggers/last_command_test.go`)
+   - `<last_command>` in trigger actions
+   - Normal variable substitution still works
+
+3. **Integration Tests** (`internal/tui/last_command_integration_test.go`)
+   - Full trigger + substitution flow
+   - Multiple variable types together
+
+### Integration Test Script ✅
+**File:** `test_ai_integration.sh`
+- Automated build and test execution
+- Manual testing instructions
+- Example workflows
+
+### Test Results
+- All existing tests continue to pass
+- New tests pass
+- No security vulnerabilities detected (CodeQL)

+
+## Example Workflows
+
+### Basic Setup
+```bash
+# Configure AI endpoint
+/configure-ai ollama http://localhost:11434/api/generate
+
+# Set prompt template
+/ai-prompt preset barsoom
+
+# Test AI
+/ai what is 2+2
+```
+
+### Automatic Error Correction
+```bash
+# Set up trigger for parsing failures
+/trigger "Huh?!" "/ai <last_command>"
+
+# Type misspelled command
+> heall
+
+# MUD responds
+Huh?!
+
+# Trigger fires automatically
+[Trigger: /ai heall]
+[AI: Generating response...]
+[AI suggests: heal]
+(sends: heal to MUD)
+```
+
+### Getting Help
+```bash
+# Ask for help without executing
+/howto heal myself
+[AI: To heal yourself, use the 'heal' command or 'cast heal' if you're a magic user]
+```
+
+## Security Summary
+
+### Security Measures
+1. **API Key Storage**: ✅ API keys stored securely in password store (`.passwords` file with 0600 permissions), not in config JSON
+2. **Input Validation**: Commands sanitized before sending to AI
+3. **Error Handling**: Network errors don't crash the client
+4. **Web Mode**: Designed to make AI requests from browser to avoid exposing API keys to server
+
+### CodeQL Results
+✅ No security vulnerabilities detected
+
+### Future Security Improvements
+- Add rate limiting for AI requests
+- Implement request timeout configuration
+- Add option to disable AI features
+
+## Web Mode Support
+
+### Current Status
+- **CLI Mode**: ✅ Fully implemented
+- **Web Mode**: 📝 TODO (marked in code)
+
+### Web Mode Design
+To implement web mode AI support:
+1. Add WebSocket message type `ai_request`
+2. Browser receives request and makes HTTP call to AI
+3. Browser sends `ai_response` message back
+4. TUI processes response
+
+This architecture prevents exposing API keys to the server.

+✅ Web mode architecture designed (implementation TODO)
+✅ Comprehensive testing and documentation
+
+The implementation is production-ready for CLI mode and provides a solid foundation for web mode support.

 **Note:** Aliases, triggers, and tick triggers support multiple commands separated by semicolons (`;`). Each command is sent sequentially with a 1-second delay.
 
+**AI Integration:** The client supports AI assistance for command suggestions. Configure an AI endpoint (OpenAI or Ollama), then use `/ai` to get command suggestions or set up a trigger like `/trigger "Huh?!" "/ai <last_command>"` to automatically get help when the MUD doesn't understand your commands.
