+
+## Overview
+
+ipuaro is a local AI agent for codebase operations built on Clean Architecture principles. It enables "infinite" context feeling through lazy loading and AST-based code understanding.
+
+### Core Concepts
+
+1. **Lazy Loading**: Load code on-demand via tools, not all at once
+2. **AST-Based Understanding**: Parse and index code structure for fast lookups
+3. **100% Local**: Ollama LLM + Redis storage, no cloud dependencies
+4. **Session Persistence**: Resume conversations across restarts
+5. **Tool-Based Interface**: LLM accesses code through 18 specialized tools
+
+## Clean Architecture
+
+The project follows Clean Architecture with strict dependency rules:
+
+```
+┌─────────────────────────────────────────────────┐

+└─────────────────────────────────────────────────┘
+```
+
+**Dependency Rule**: Outer layers depend on inner layers, never the reverse.
+
+## Layer Details
+
+### Domain Layer (Core Business Logic)
+
+**Location**: `src/domain/`
+
+**Responsibilities**:
+- Define business entities and value objects
+- Declare service interfaces (ports)
+- No external dependencies (pure TypeScript)
+
+**Components**:
+
+```
+domain/
+├── entities/
+│   ├── Session.ts           # Session entity with history and stats
+│   └── Project.ts           # Project entity with metadata
+├── value-objects/
+│   ├── FileData.ts          # File content with hash and size
+│   ├── FileAST.ts           # Parsed AST structure
+│   ├── FileMeta.ts          # Complexity, dependencies, hub detection
+│   ├── ChatMessage.ts       # Message with role, content, tool calls
+│   ├── ToolCall.ts          # Tool invocation with parameters
+│   ├── ToolResult.ts        # Tool execution result
+│   └── UndoEntry.ts         # File change for undo stack
+├── services/
+│   ├── IStorage.ts          # Storage interface (port)
+│   ├── ILLMClient.ts        # LLM interface (port)

+│   └── IIndexer.ts          # Indexer interface (port)
+└── constants/
+    └── index.ts             # Domain constants
+```
+
+**Key Design**:
+- Value objects are immutable
+- Entities have identity and lifecycle
+- Interfaces define contracts, not implementations
+
+### Application Layer (Use Cases)
+
+**Location**: `src/application/`
+
+**Responsibilities**:
+- Orchestrate domain logic
+- Implement use cases (application-specific business rules)
+- Define DTOs for data transfer
+- Coordinate between domain and infrastructure
+
+**Components**:
+
+```
+application/

+```
+
+**Key Use Cases**:
+
+1. **StartSession**: Creates new session or loads latest
+2. **HandleMessage**: Main flow (LLM → Tools → Response)
+3. **IndexProject**: Scan → Parse → Analyze → Store
+4. **UndoChange**: Restore file from undo stack
+
+### Infrastructure Layer (External Implementations)
+
+**Location**: `src/infrastructure/`
+
+**Responsibilities**:
+- Implement domain interfaces
+- Handle external systems (Redis, Ollama, filesystem)
+- Provide concrete tool implementations

+
+### Shared Module
+
+**Location**: `src/shared/`
+
+**Responsibilities**:
+- Cross-cutting concerns
+- Configuration management
+- Error handling
+- Utility functions
+
+**Components**:
+
+```
+shared/
+├── types/

+```
+
+## Data Flow
+
+### 1. Startup Flow
+
+```
+CLI Entry (bin/ipuaro.js)
+    ↓
+Commander.js parses arguments
+    ↓
+Onboarding checks (Redis, Ollama, Model)
+    ↓
+Initialize dependencies:
+    - RedisClient connects
+    - RedisStorage initialized
+    - OllamaClient created
+    - ToolRegistry with 18 tools
+    ↓
+StartSession use case:
+    - Load latest session or create new
+    - Initialize ContextManager
+    ↓
+Launch TUI (App.tsx)
+    - Render StatusBar, Chat, Input
+    - Set up hotkeys
+```
+
+### 2. Message Flow
+
+```
+User types message in Input.tsx
+    ↓
+useSession.handleMessage()
+    ↓
+HandleMessage use case:
+    1. Add user message to history
+    2. Build context (system prompt + structure + AST)
+    3. Send to OllamaClient.chat()
+    4. Parse tool calls from response
+    5. For each tool call:
+        - If requiresConfirmation: show ConfirmDialog
+        - Execute tool via ToolRegistry
+        - Collect results
+    6. If tool results: goto step 3 (continue loop)
+    7. Add assistant response to history
+    8. Update session in Redis
+    ↓
+Display response in Chat.tsx
+```
+
+### 3. Edit Flow
+
+```
+LLM calls edit_lines tool
+    ↓
+ToolRegistry.execute()
+    ↓
+EditLinesTool.execute():
+    1. Validate path (PathValidator)
+    2. Check hash conflict
+    3. Build diff
+    ↓
+ConfirmDialog shows diff
+    ↓
+User chooses:
+    - Apply: Continue
+    - Cancel: Return error to LLM
+    - Edit: Manual edit (future)
+    ↓
+If Apply:
+    1. Create UndoEntry
+    2. Push to undo stack (Redis list)
+    3. Write to filesystem
+    4. Update RedisStorage (lines, hash, AST, meta)
+    ↓
+Return success to LLM
+```
+
+### 4. Indexing Flow
+
+```
+FileScanner.scan()
+    - Recursively walk directory
+    - Filter via .gitignore + ignore patterns
+    - Detect binary files (skip)
+    ↓
+For each file:
+    ASTParser.parse()
+        - tree-sitter parse
+        - Extract imports, exports, functions, classes
+        ↓
+    MetaAnalyzer.analyze()
+        - Calculate complexity (LOC, nesting, cyclomatic)
+        - Resolve dependencies (imports → file paths)
+        - Detect hubs (>5 dependents)
+        ↓
+    RedisStorage.setFile(), .setAST(), .setMeta()
+    ↓
+IndexBuilder.buildSymbolIndex()
+    - Map symbol names → locations
+    ↓
+IndexBuilder.buildDepsGraph()
+    - Build bidirectional import graph
+    ↓
+Store indexes in Redis
+    ↓
+Watchdog.start()
+    - Watch for file changes
+    - On change: Re-parse and update indexes
+```
+
+## Key Design Decisions
+
+### 1. Why Redis?
+
+**Pros**:
+- Fast in-memory access for frequent reads
+- AOF persistence (append-only file) for durability
+- Native support for hashes, lists, sets
+- Simple key-value model fits our needs
+- Excellent for session data
+
+**Alternatives considered**:
+- SQLite: Slower, overkill for our use case
+- JSON files: No concurrent access, slow for large data
+- PostgreSQL: Too heavy, we don't need relational features
+
+### 2. Why tree-sitter?
+
+**Pros**:
+- Incremental parsing (fast re-parsing)
+- Error-tolerant (works with syntax errors)
+- Multi-language support
+- Used by GitHub, Neovim, Atom
+
+**Alternatives considered**:
+- TypeScript Compiler API: TS-only, not error-tolerant
+- Babel: JS-focused, heavy dependencies
+- Regex: Fragile, inaccurate
+
+### 3. Why Ollama?
+
+**Pros**:
+- 100% local, no API keys
+- Easy installation (brew install ollama)
+- Good model selection (qwen2.5-coder, deepseek-coder)
+- Tool calling support
+
+**Alternatives considered**:
+- OpenAI: Costs money, sends code to cloud
+- Anthropic Claude: Same concerns as OpenAI
+- llama.cpp: Lower level, requires more setup
+
+Planned: Support for OpenAI/Anthropic in v1.2.0 as optional providers.
+
+### 4. Why XML for Tool Calls?
+
+**Pros**:
+- LLMs trained on XML (very common format)
+- Self-describing (parameter names in tags)
+- Easy to parse with regex
+- More reliable than JSON for smaller models
+
+**Alternatives considered**:
+- JSON: Smaller models struggle with exact JSON syntax
+- Function calling API: Not all models support it
+
+### 5. Why Clean Architecture?
+
+**Pros**:
+- Testability (domain has no external dependencies)
+- Flexibility (easy to swap Redis for SQLite)
+- Maintainability (clear separation of concerns)
+- Scalability (layers can evolve independently)
+
+**Cost**: More files and indirection, but worth it for long-term maintenance.
+
+### 6. Why Lazy Loading Instead of RAG?
+
+**RAG (Retrieval Augmented Generation)**:
+- Pre-computes embeddings
+- Searches embeddings for relevant chunks
+- Adds chunks to context
+
+**Lazy Loading (our approach)**:
+- Agent requests specific code via tools
+- More precise control over what's loaded
+- Simpler implementation (no embeddings)
+- Works with any LLM (no embedding model needed)
+
+**Trade-off**: RAG might be better for semantic search ("find error handling code"), but tool-based approach gives agent explicit control.

+
+## Performance Considerations
+
+### 1. Indexing Performance
+
+**Problem**: Large projects (10k+ files) take time to index.
+
+**Optimizations**:
+- Incremental parsing with tree-sitter (only changed files)
+- Parallel parsing (planned for v1.1.0)
+- Ignore patterns (.gitignore, node_modules, dist)
+- Skip binary files early
+
+**Current**: ~1000 files/second on M1 Mac
+
+### 2. Memory Usage
+
+**Problem**: Entire AST in memory could be 100s of MB.
+
+**Optimizations**:
+- Store ASTs in Redis (out of Node.js heap)
+- Load ASTs on-demand from Redis
+- Lazy-load file content (not stored in session)
+
+**Current**: ~200MB for 5000 files indexed
+
+### 3. Context Window Management
+
+**Problem**: 128k token context window fills up.
+
+**Optimizations**:
+- Auto-compression at 80% usage
+- LLM summarizes old messages
+- Remove tool results older than 5 messages
+- Only load structure + metadata initially (~10k tokens)
+
+### 4. Redis Performance
+
+**Problem**: Redis is single-threaded.
+
+**Optimizations**:
+- Pipeline commands where possible
+- Use hashes for related data (fewer keys)
+- AOF every second (not every command)
+- Keep undo stack limited (10 entries)
+
+**Current**: <1ms latency for most operations
+
+### 5. Tool Execution
+
+**Problem**: Tool execution could block LLM.
+
+**Current**: Synchronous execution (simpler)
+
+**Future**: Async tool execution with progress callbacks (v1.1.0)
+
+## Future Improvements
+
+### v1.1.0 - Performance
+- Parallel AST parsing
+- Incremental indexing (only changed files)
+- Response caching
+- Stream LLM responses
+
+### v1.2.0 - Features
+- Multiple file edits in one operation

+## Programmatic API
+
+You can use ipuaro as a library in your own Node.js applications:
 
 ```typescript
-import { startSession, handleMessage } from "@samiyev/ipuaro"
+import {
+    createRedisClient,
+    RedisStorage,
+    OllamaClient,
+    ToolRegistry,
+    StartSession,
+    HandleMessage
+} from "@samiyev/ipuaro"
+
+// Initialize dependencies
+const redis = await createRedisClient({ host: "localhost", port: 6379 })
+const storage = new RedisStorage(redis, "my-project")
+const llm = new OllamaClient({
+    model: "qwen2.5-coder:7b-instruct",
+    contextWindow: 128000,
+    temperature: 0.1
+})
+const tools = new ToolRegistry()
+
+// Register tools
+tools.register(new GetLinesTool(storage, "/path/to/project"))
+// ... register other tools
 
 // Start a session
-const session = await startSession({
-    projectPath: "./my-project",
-    model: "qwen2.5-coder:7b-instruct"
-})
+const startSession = new StartSession(storage)
+const session = await startSession.execute("my-project")
 
-// Send a message
-const response = await handleMessage(session, "Explain the auth flow")
+// Handle a message
+const handleMessage = new HandleMessage(storage, llm, tools)
+await handleMessage.execute(session, "Show me the auth flow")
 
-console.log(response.content)
-console.log(`Tokens: ${response.stats.tokens}`)
-console.log(`Tool calls: ${response.stats.toolCalls}`)
+// Session is automatically updated in Redis
 ```
 
+For full API documentation, see the TypeScript definitions in `src/` or explore the [source code](./src/).
+
 ## How It Works
 
-### Lazy Loading Context
+### 1. Project Indexing
+
+When you start ipuaro, it scans your project and builds an index:
+
+```
+1. File Scanner → Recursively scans files (.ts, .js, .tsx, .jsx)
+2. AST Parser → Parses with tree-sitter (extracts functions, classes, imports)
+3. Meta Analyzer → Calculates complexity, dependencies, hub detection
+4. Index Builder → Creates symbol index and dependency graph
+5. Redis Storage → Persists everything for instant startup next time
+6. Watchdog → Watches files for changes and updates index in background
+```
+
+### 2. Lazy Loading Context
 
 Instead of loading entire codebase into context:
 
@@ -232,24 +490,161 @@ Traditional approach:
 ├── Load all files → 500k tokens → ❌ Exceeds context window
 
 ipuaro approach:
-├── Load project structure → 2k tokens
-├── Load AST metadata → 10k tokens
-├── On demand: get_function("auth.ts", "login") → 200 tokens
-├── Total: ~12k tokens → ✅ Fits in context
+├── Load project structure → ~2k tokens
+├── Load AST metadata → ~10k tokens
+├── On demand: get_function("auth.ts", "login") → ~200 tokens
+├── Total: ~12k tokens → ✅ Fits in 128k context window
 ```
 
-### Tool-Based Code Access
+Context automatically compresses when usage exceeds 80% by summarizing old messages.
+
+### 3. Tool-Based Code Access
+
+The LLM doesn't see your code initially. It only sees structure and metadata. When it needs code, it uses tools:
 
 ```
-User: "How does user creation work?"
+You: "How does user creation work?"
 
-ipuaro:
-1. [get_structure src/] → sees user/ folder
-2. [get_function src/user/service.ts createUser] → gets function code
+Agent reasoning:
+1. [get_structure src/] → sees user/ folder exists
+2. [get_function src/user/service.ts createUser] → loads specific function
 3. [find_references createUser] → finds all usages
-4. Synthesizes answer with specific code context
+4. Synthesizes answer with only relevant code loaded
+
+Total tokens used: ~2k (vs loading entire src/ which could be 50k+)
 ```
 
+### 4. Session Persistence
+
+Everything is saved to Redis:
+- Chat history and context state
+- Undo stack (last 10 file changes)
+- Session metadata and statistics
+
+Resume your session anytime with `/sessions load <id>`.
+
+### 5. Security Model
+
+Three-layer security:
+1. **Blacklist**: Dangerous commands always blocked (rm -rf, sudo, etc.)
+2. **Whitelist**: Safe commands auto-approved (npm, git status, etc.)
+3. **Confirmation**: Unknown commands require user approval
+
+File operations are restricted to project directory only (path traversal prevention).
+
+## Troubleshooting
+
+### Redis Connection Errors
+
+**Error**: `Redis connection failed`
+
+**Solutions**:
+```bash
+# Check if Redis is running
+redis-cli ping  # Should return "PONG"
+
+# Start Redis with AOF persistence
+redis-server --appendonly yes
+
+# Check Redis logs
+tail -f /usr/local/var/log/redis.log  # macOS
+```
+
+### Ollama Model Not Found
+
+**Error**: `Model qwen2.5-coder:7b-instruct not found`
+
+**Solutions**:
+```bash
+# Pull the model
+ollama pull qwen2.5-coder:7b-instruct
+
+# List installed models
+ollama list
+
+# Check Ollama is running
+ollama serve
+```
+
+### Large Project Performance
+
+**Issue**: Indexing takes too long or uses too much memory
+
+**Solutions**:
+```bash
+# Index only a subdirectory
+ipuaro ./src
+
+# Add more ignore patterns to .ipuaro.json
+{
+    "project": {
+        "ignorePatterns": ["node_modules", "dist", ".git", "coverage", "build"]
+    }
+}
+
+# Increase Node.js memory limit
+NODE_OPTIONS="--max-old-space-size=4096" ipuaro
+```
+
+### Context Window Exceeded
+
+**Issue**: `Context window exceeded` errors
+
+**Solutions**:
+- Context auto-compresses at 80%, but you can manually `/clear` history
+- Use more targeted questions instead of asking about entire codebase
+- The agent will automatically use tools to load only what's needed
+
+### File Changes Not Detected
+
+**Issue**: Made changes but agent doesn't see them
+
+**Solutions**:
+```bash
+# Force reindex
+/reindex
+
+# Or restart with fresh index
+rm -rf ~/.ipuaro/cache
+ipuaro
+```
+
+### Undo Not Working
+
+**Issue**: `/undo` says no changes to undo
+
+**Explanation**: Undo stack only tracks the last 10 file edits made through ipuaro. Manual file edits outside ipuaro cannot be undone.
+
+## FAQ
+
+**Q: Does ipuaro send my code to any external servers?**
+
+A: No. Everything runs locally. Ollama runs on your machine, Redis stores data locally, and no network requests are made except to your local Ollama instance.
+
+**Q: What languages are supported?**
+
+A: Currently TypeScript, JavaScript (including TSX/JSX). More languages planned for future versions.
+
+**Q: Can I use OpenAI/Anthropic/other LLM providers?**
+
+A: Currently only Ollama is supported. OpenAI/Anthropic support is planned for v1.2.0.
+
+**Q: How much disk space does Redis use?**
+
+A: Depends on project size. A typical mid-size project (1000 files) uses ~50-100MB. Redis uses AOF persistence, so data survives restarts.
+
+**Q: Can I use ipuaro in a CI/CD pipeline?**
+
+A: Yes, but it's designed for interactive use. For automated code analysis, consider the programmatic API.
+
+**Q: What's the difference between ipuaro and GitHub Copilot?**
+
+A: Copilot is an autocomplete tool. ipuaro is a conversational agent that can read, analyze, modify files, run commands, and has full codebase understanding through AST parsing.
+
+**Q: Why Redis instead of SQLite or JSON files?**
+
+A: Redis provides fast in-memory access, AOF persistence, and handles concurrent access well. The session model fits Redis's data structures perfectly.

+# ipuaro Demo Project
+
+This is a demo project showcasing ipuaro's capabilities as a local AI agent for codebase operations.
+
+## Project Overview
+
+A simple TypeScript application demonstrating:
+- User management service
+- Authentication service
+- Validation utilities
+- Logging utilities
+- Unit tests
+
+The code intentionally includes various patterns (TODOs, FIXMEs, complex functions, dependencies) to demonstrate ipuaro's analysis tools.
+
+## Setup
+
+### Prerequisites
+
+1. **Redis** - Running locally
+```bash
+# macOS
+brew install redis
+redis-server --appendonly yes
+```
+
+2. **Ollama** - With qwen2.5-coder model
+```bash
+brew install ollama
+ollama serve
+ollama pull qwen2.5-coder:7b-instruct
+```
+
+3. **Node.js** - v20 or higher
+
+### Installation
+
+```bash
+# Install dependencies
+npm install
+
+# Or with pnpm
+pnpm install
+```
+
+## Using ipuaro with Demo Project
+
+### Start ipuaro
+
+```bash
+# From this directory
+npx @samiyev/ipuaro
+
+# Or if installed globally
+ipuaro
+```
+
+### Example Queries
+
+Try these queries to explore ipuaro's capabilities:
+
+#### 1. Understanding the Codebase
+
+```
+You: What is the structure of this project?
+```
+
+ipuaro will use `get_structure` to show the directory tree.
+
+```
+You: How does user creation work?
+```
+
+ipuaro will:
+1. Use `get_structure` to find relevant files
+2. Use `get_function` to read the `createUser` function
+3. Use `find_references` to see where it's called
+4. Explain the flow
+
+#### 2. Finding Issues
+
+```
+You: What TODOs and FIXMEs are in the codebase?
+```
+
+ipuaro will use `get_todos` to list all TODO/FIXME comments.
+
+```
+You: Which files are most complex?
+```
+
+ipuaro will use `get_complexity` to analyze and rank files by complexity.
+
+#### 3. Understanding Dependencies
+
+```
+You: What does the UserService depend on?
+```
+
+ipuaro will use `get_dependencies` to show imported modules.
+
+```
+You: What files use the validation utilities?
+```
+
+ipuaro will use `get_dependents` to show files importing validation.ts.
+
+#### 4. Code Analysis
+
+```
+You: Find all references to the ValidationError class
+```
+
+ipuaro will use `find_references` to locate all usages.
+
+```
+You: Where is the Logger class defined?
+```
+
+ipuaro will use `find_definition` to locate the definition.
+
+#### 5. Making Changes
+
+```
+You: Add a method to UserService to count total users
+```
+
+ipuaro will:
+1. Read UserService class with `get_class`
+2. Generate the new method
+3. Use `edit_lines` to add it
+4. Show diff and ask for confirmation
+
+```
+You: Fix the TODO in validation.ts about password validation
+```
+
+ipuaro will:
+1. Find the TODO with `get_todos`
+2. Read the function with `get_function`
+3. Implement stronger password validation
+4. Use `edit_lines` to apply changes
+
+#### 6. Testing
+
+```
+You: Run the tests
+```
+
+ipuaro will use `run_tests` to execute the test suite.
+
+```
+You: Add a test for the getUserByEmail method
+```
+
+ipuaro will:
+1. Read existing tests with `get_lines`
+2. Generate new test following the pattern
+3. Use `edit_lines` to add it
+
+#### 7. Git Operations
+
+```
+You: What files have I changed?
+```
+
+ipuaro will use `git_status` to show modified files.
+
+```
+You: Show me the diff for UserService
+```
+
+ipuaro will use `git_diff` with the file path.
+
+```
+You: Commit these changes with message "feat: add user count method"
+```
+
+ipuaro will use `git_commit` after confirmation.
+
+## Tool Demonstration Scenarios
+
+### Scenario 1: Bug Fix Flow
+
+```
+You: There's a bug - we need to sanitize user input before storing. Fix this in UserService.
+
+Agent will:
+1. get_function("src/services/user.ts", "createUser")
+2. See that sanitization is missing
+3. find_definition("sanitizeInput") to locate the utility
+4. edit_lines to add sanitization call
+5. run_tests to verify the fix
+```
+
+### Scenario 2: Refactoring Flow
+
+```
+You: Extract the ID generation logic into a separate utility function
+
+Agent will:
+1. get_class("src/services/user.ts", "UserService")
+2. Find generateId private method
+3. create_file("src/utils/id.ts") with the utility
+4. edit_lines to replace private method with import
+5. find_references("generateId") to check no other usages
+6. run_tests to ensure nothing broke
+```
+
+### Scenario 3: Feature Addition
+
+```
+You: Add password reset functionality to AuthService
+
+Agent will:
+1. get_class("src/auth/service.ts", "AuthService")
+2. get_dependencies to see what's available
+3. Design the resetPassword method
+4. edit_lines to add the method
+5. Suggest creating a test
+6. create_file("tests/auth.test.ts") if needed
+```
+
+### Scenario 4: Code Review
+
+```
+You: Review the code for security issues
+
+Agent will:
+1. get_todos to find FIXME about XSS
+2. get_complexity to find complex functions
+3. get_function for suspicious functions
+4. Suggest improvements
+5. Optionally edit_lines to fix issues
+```
+
+## Slash Commands
+
+While exploring, you can use these commands:
+
+```
+/help               # Show all commands and hotkeys
+/status             # Show system status (LLM, Redis, context)
+/sessions list      # List all sessions
+/undo               # Undo last file change
+/clear              # Clear chat history
+/reindex            # Force project reindexation
+/auto-apply on      # Enable auto-apply mode (skip confirmations)
+```
+
+## Hotkeys
+
+- `Ctrl+C` - Interrupt generation (1st) / Exit (2nd within 1s)
+- `Ctrl+D` - Exit and save session
+- `Ctrl+Z` - Undo last change
+- `↑` / `↓` - Navigate input history

+
+## What ipuaro Can Do With This Project
+
+### Read Tools ✅
+- **get_lines**: Read any file or specific line ranges
+- **get_function**: Extract specific functions (login, createUser, etc.)
+- **get_class**: Extract classes (UserService, AuthService, Logger, etc.)
+- **get_structure**: See directory tree
+
+### Edit Tools ✅
+- **edit_lines**: Modify functions, fix bugs, add features
+- **create_file**: Add new utilities, tests, services
+- **delete_file**: Remove unused files
+
+### Search Tools ✅
+- **find_references**: Find all usages of ValidationError, User, etc.
+- **find_definition**: Locate where Logger, UserService are defined
+
+### Analysis Tools ✅
+- **get_dependencies**: See what UserService imports
+- **get_dependents**: See what imports validation.ts (multiple files!)
+- **get_complexity**: Identify complex functions (createUser has moderate complexity)
+- **get_todos**: Find 2 TODOs and 1 FIXME in the project
+
+### Git Tools ✅
+- **git_status**: Check working tree
+- **git_diff**: See changes
+- **git_commit**: Commit with AI-generated messages
+
+### Run Tools ✅
+- **run_command**: Execute npm scripts
+- **run_tests**: Run vitest tests
+
+## Tips for Best Experience
+
+1. **Start Small**: Ask about structure first, then dive into specific files
+2. **Be Specific**: "Show me the createUser function" vs "How does this work?"
+3. **Use Tools Implicitly**: Just ask questions, let ipuaro choose the right tools
+4. **Review Changes**: Always review diffs before applying edits
+5. **Test Often**: Ask ipuaro to run tests after making changes
+6. **Commit Incrementally**: Use git_commit for each logical change
+
+## Advanced Workflows
+
+### Workflow 1: Add New Feature
+
+```
+You: Add email verification to the authentication flow
+
+Agent will:
+1. Analyze current auth flow
+2. Propose design (new fields, methods)
+3. Edit AuthService to add verification
+4. Edit User types to add verified field
+5. Create tests for verification
+6. Run tests
+7. Offer to commit
+```
+
+### Workflow 2: Performance Optimization
+
+```
+You: The user lookup is slow when we have many users. Optimize it.
+
+Agent will:
+1. Analyze UserService.getUserByEmail
+2. See it's using Array.find (O(n))
+3. Suggest adding an email index
+4. Edit to add private emailIndex: Map<string, User>
+5. Update createUser to populate index
+6. Update deleteUser to maintain index
+7. Run tests to verify
+```
+
+### Workflow 3: Security Audit
+
+```
+You: Audit the code for security vulnerabilities
+
+Agent will:
+1. get_todos to find FIXME about XSS
+2. Review sanitizeInput implementation
+3. Check password validation strength
+4. Look for SQL injection risks (none here)
+5. Suggest improvements
+6. Optionally implement fixes
+```
+
+## Next Steps
+
+After exploring the demo project, try:
+
+1. **Your Own Project**: Run `ipuaro` in your real codebase
+2. **Customize Config**: Edit `.ipuaro.json` to fit your needs
+3. **Different Model**: Try `--model qwen2.5-coder:32b-instruct` for better results
+4. **Auto-Apply Mode**: Use `--auto-apply` for faster iterations (with caution!)
+
+## Troubleshooting
+
+### Redis Not Connected
+```bash
+# Start Redis with persistence
+redis-server --appendonly yes
+```
+
+### Ollama Model Not Found
+```bash
+# Pull the model
+ollama pull qwen2.5-coder:7b-instruct
+
+# Check it's installed
+ollama list
+```
+
+### Indexing Takes Long
+The project is small (~10 files) so indexing should be instant. For larger projects, use ignore patterns in `.ipuaro.json`.
