## 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:
```
┌─────────────────────────────────────────────────┐
│ TUI Layer │ ← Ink/React components
│ (Framework) │
├─────────────────────────────────────────────────┤
│ CLI Layer │ ← Commander.js entry
│ (Interface) │
├─────────────────────────────────────────────────┤
│ Infrastructure Layer │ ← External adapters
│ (Storage, LLM, Indexer, Tools, Security) │
├─────────────────────────────────────────────────┤
│ Application Layer │ ← Use cases & DTOs
│ (StartSession, HandleMessage, etc.) │
├─────────────────────────────────────────────────┤
│ Domain Layer │ ← Business logic
│ (Entities, Value Objects, Service Interfaces) │
└─────────────────────────────────────────────────┘
```
**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)
│ ├── ITool.ts # Tool 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/
├── use-cases/
│ ├── StartSession.ts # Initialize or load session
│ ├── HandleMessage.ts # Main message orchestrator
│ ├── IndexProject.ts # Project indexing workflow
│ ├── ExecuteTool.ts # Tool execution with validation
│ └── UndoChange.ts # Revert file changes
├── dtos/
│ ├── SessionDto.ts # Session data transfer object
│ ├── MessageDto.ts # Message DTO
│ └── ToolCallDto.ts # Tool call DTO
├── mappers/
│ └── SessionMapper.ts # Domain ↔ DTO conversion
└── interfaces/
└── IToolRegistry.ts # Tool registry interface
```
**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
- Security and validation
**Components**:
```
infrastructure/
├── storage/
│ ├── RedisClient.ts # Redis connection wrapper
│ ├── RedisStorage.ts # IStorage implementation
│ └── schema.ts # Redis key schema
├── llm/
│ ├── OllamaClient.ts # ILLMClient implementation
│ ├── prompts.ts # System prompts
│ └── ResponseParser.ts # Parse XML tool calls
├── indexer/
│ ├── FileScanner.ts # Recursive file scanning
│ ├── ASTParser.ts # tree-sitter parsing
│ ├── MetaAnalyzer.ts # Complexity and dependencies
│ ├── IndexBuilder.ts # Symbol index + deps graph
│ └── Watchdog.ts # File watching (chokidar)
├── tools/ # 18 tool implementations
│ ├── registry.ts
│ ├── read/ # GetLines, GetFunction, GetClass, GetStructure
│ ├── edit/ # EditLines, CreateFile, DeleteFile
│ ├── search/ # FindReferences, FindDefinition
│ ├── analysis/ # GetDependencies, GetDependents, GetComplexity, GetTodos
│ ├── git/ # GitStatus, GitDiff, GitCommit
│ └── run/ # RunCommand, RunTests
└── security/
├── Blacklist.ts # Dangerous commands
├── Whitelist.ts # Safe commands
└── PathValidator.ts # Path traversal prevention
```
**Key Implementations**:
1. **RedisStorage**: Uses Redis hashes for files/AST/meta, lists for undo
2. **OllamaClient**: HTTP API client with tool calling support
3. **ASTParser**: tree-sitter for TS/JS/TSX/JSX parsing
4. **ToolRegistry**: Manages tool lifecycle and execution
### TUI Layer (Terminal UI)
**Location**: `src/tui/`
**Responsibilities**:
- Render terminal UI with Ink (React for terminal)
- Handle user input and hotkeys
- Display chat history and status
**Components**:
```
tui/
├── App.tsx # Main app shell
├── components/
│ ├── StatusBar.tsx # Top status bar
│ ├── Chat.tsx # Message history display
│ ├── Input.tsx # User input with history
│ ├── DiffView.tsx # Inline diff display
│ ├── ConfirmDialog.tsx # Edit confirmation
│ ├── ErrorDialog.tsx # Error handling
│ └── Progress.tsx # Progress bar (indexing)
└── hooks/
├── useSession.ts # Session state management
├── useHotkeys.ts # Keyboard shortcuts
└── useCommands.ts # Slash command handling
```
**Key Features**:
- Real-time status updates (context usage, session time)
- Input history with ↑/↓ navigation
- Hotkeys: Ctrl+C (interrupt), Ctrl+D (exit), Ctrl+Z (undo)
- Diff preview for edits with confirmation
- Error recovery with retry/skip/abort options
### CLI Layer (Entry Point)
**Location**: `src/cli/`
**Responsibilities**:
- Command-line interface with Commander.js
- Dependency injection and initialization
- Onboarding checks (Redis, Ollama, model)
**Components**:
```
cli/
├── index.ts # Commander.js setup
└── commands/
├── start.ts # Start TUI (default command)
├── init.ts # Create .ipuaro.json config
└── index-cmd.ts # Index-only command
```
**Commands**:
1. `ipuaro [path]` - Start TUI in directory
2. `ipuaro init` - Create config file
3. `ipuaro index` - Index without TUI
### Shared Module
**Location**: `src/shared/`
**Responsibilities**:
- Cross-cutting concerns
- Configuration management
- Error handling
- Utility functions
**Components**:
```
shared/
├── types/
│ └── index.ts # Shared TypeScript types
├── constants/
│ ├── config.ts # Config schema and loader
│ └── messages.ts # User-facing messages
├── utils/
│ ├── hash.ts # MD5 hashing
│ └── tokens.ts # Token estimation
└── errors/
├── IpuaroError.ts # Custom error class
└── ErrorHandler.ts # Error handling service
```
## 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
- Batch operations
- Custom prompt templates
- OpenAI/Anthropic provider support
### v1.3.0 - Extensibility
- Plugin system for custom tools
- LSP integration
- Multi-language support (Python, Go, Rust)
- Custom indexing rules

For complete tool documentation with all parameters and options, see [TOOLS.md](./TOOLS.md).
## 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 +473,161 @@ 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.
