๐ ๏ธ Technical Deep Dive
- Architecture: Modular design separating CLI frontend from Core backend, enabling independent development and future frontend extensions[2]
- Input Processing: Supports direct text, slash commands (
/help,/clear,/model), at-commands (@file), and shell execution commands (!command)[2] - Session Management: Maintains conversation history with resumption capabilities and multiple simultaneous sessions[3]
- Context Window: Qwen3-Coder supports 256K+ tokens, enabling processing of large codebases[4]
- Reasoning Modes: Hybrid architecture with thinking mode (deep step-by-step reasoning) and non-thinking mode (fast responses) with dynamic switching[4]
- Tool System: Extensible tool registration and execution framework supporting MCP server integration[2]
- Configuration: JSON-based settings with environment variables and CLI arguments; supports vim mode, theme customization, model selection, and privacy controls[2]
