feat: Complete hanzo dev chat-first REPL with multi-orchestrator support

- Chat-first interface (natural language by default)
- Claude Desktop-style UI with light gray borders
- Support for multiple orchestrators (GPT-5, Codex, Claude, local models)
- CLI tool integration (OpenAI CLI, Claude Desktop, Gemini CLI, Hanzo IDE)
- System 2 thinking with critic agents
- Comprehensive test coverage with real AI validation
- Version bump to 0.3.19

# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Repository Overview
This is the Hanzo Python SDK monorepo containing the official Python client library for the Hanzo AI platform and related packages. The SDK provides unified access to 100+ LLM providers through a single OpenAI-compatible API interface, with enterprise features like cost tracking, rate limiting, and observability.
## Project Structure
This is a monorepo managed with `rye` containing multiple interconnected packages:
### Main Package
- **`pkg/hanzoai/`** - Core SDK for Hanzo AI platform
- OpenAI-compatible API client
- Support for 100+ LLM providers
- Cost tracking and rate limiting
- Team and organization management
- File operations and fine-tuning
### Sub-Packages (in `pkg/` directory)
- **`hanzo/`** - CLI and orchestration tools
- **`hanzo-mcp/`** - Model Context Protocol implementation
- **`hanzo-agents/`** - Agent framework and swarm orchestration
- **`hanzo-memory/`** - Memory and knowledge base management
- **`hanzo-network/`** - Distributed network capabilities
- **`hanzo-repl/`** - Interactive REPL for AI chat
- **`hanzo-aci/`** - AI code intelligence and editing tools
## Development Commands
### Setup and Installation
```bash
# Install Python via uv (required)
make install-python
# Complete setup (venv + dependencies)
make setup
# Install specific package for development
uv pip install -e .
uv pip install -e ./pkg/hanzo-agents
```
### Testing
```bash
# Run all tests
make test
./scripts/test
# Run specific test file
uv run pytest tests/api_resources/test_chat.py -v
# Run tests with specific pattern
uv run pytest -k "pattern" -v
# Run tests with coverage
uv run pytest --cov=hanzoai tests/
# Run tests for specific package
make test-agents # Test hanzo-agents
make test-mcp # Test hanzo-mcp
```
### Code Quality
```bash
# Format code
make format
ruff format pkg/
# Run linting
make lint
ruff check . --fix
# Type checking
make check-types
uv run mypy pkg/hanzoai --ignore-missing-imports
uv run pyright
```
### Building and Publishing
```bash
# Build all packages
make build
# Build specific package
uv build .
cd pkg/hanzo-mcp && uv build
# Check packages before publishing
make publish-check
```
## Architecture and Code Organization
### Client Architecture
The SDK uses a code-generated client architecture (via Stainless):
- **Base Client** (`_base_client.py`) - HTTP client with retry logic
- **Main Client** (`_client.py`) - `Hanzo` and `AsyncHanzo` classes
- **Resources** (`resources/`) - API endpoint implementations
- Each resource follows a consistent pattern with sync/async support
- Resources are organized by API domain (chat, files, models, etc.)
- **Types** (`types/`) - Pydantic models for request/response types
### Key Patterns
#### Resource Pattern
All API resources follow this structure:
```python
class ResourceWithRawResponse:
def __init__(self, resource: Resource) -> None:
self._resource = resource
# Expose methods with raw response wrapper
class AsyncResourceWithRawResponse:
# Async version of the above
```
#### Testing Pattern
Tests use `respx` for HTTP mocking (no external dependencies):
```python
@pytest.mark.respx(base_url=base_url)
def test_method(client: Hanzo, respx_mock: MockRouter) -> None:
respx_mock.get("/endpoint").mock(return_value=Response(200, json={}))
# Test implementation
```
### Important Implementation Details
1. **Environment Variables**:
- `HANZO_API_KEY` - API authentication
- `HANZO_BASE_URL` - API base URL (default: https://api.hanzo.ai)
- `HANZO_LOG` - Logging level (debug/info/warning/error)
2. **Dependency Management**:
- Uses `rye` for workspace management
- `uv` for fast Python package operations
- Separate lock files for production and dev dependencies
3. **Test Infrastructure**:
- All tests use mocked responses (no external API calls)
- 100% test coverage requirement
- Tests organized by resource in `tests/api_resources/`
4. **Code Generation**:
- Many files are auto-generated from OpenAPI spec
- Look for "File generated from our OpenAPI spec" header
- Manual changes to generated files will be overwritten
## Package-Specific Notes
### hanzo-mcp
- Implements Model Context Protocol for tool capabilities
- Includes filesystem, search, and agent delegation tools
- Can be installed to Claude Desktop with `make install-desktop`
### hanzo-agents
- Provides agent swarm orchestration
- Supports both hierarchical and peer network architectures
- Includes MCP tool integration for recursive agent calls
### hanzo CLI
- Main entry point: `hanzo.cli:main`
- Subcommands for auth, chat, mcp, network operations
- Supports local AI orchestration with `hanzo dev`
## Common Tasks
### Adding New API Endpoints
1. Update OpenAPI spec if using code generation
2. Add resource class in `resources/` directory
3. Add types in `types/` directory
4. Add tests in `tests/api_resources/`
5. Update `__init__.py` exports
### Running Local Development Server
```bash
# Start mock server for testing
python run_mock_server.py
# Run hanzo dev with local orchestration
hanzo dev --orchestrator local:llama-3.2-3b
```
### Debugging Tests
```bash
# Run with verbose output
uv run pytest -vv tests/
# Run with print statements visible
uv run pytest -s tests/
# Run specific test with debugging
uv run pytest tests/test_client.py::TestClient::test_method -vv
```
## CI/CD Pipeline
The repository uses GitHub Actions for CI:
- **Linting** - Runs on every push/PR with `ruff`
- **Testing** - Full test suite with coverage reporting
- **Type Checking** - Both `mypy` and `pyright`
- **Package Testing** - Separate CI for each sub-package
## Important Conventions
1. **No Print Statements**: Use logging instead, except in CLI tools
2. **Type Hints Required**: All functions must have type annotations
3. **Async Support**: All API methods have both sync and async versions
4. **Error Handling**: Use specific exception classes from `_exceptions.py`
5. **Documentation**: Docstrings for public APIs, examples in `/examples`
