## Overview

Klaude is a terminal chat coding assistant: the user submits a prompt, the app sends conversation context to a streaming model, executes any returned tools, and renders the reply and status in the terminal UI. The graph includes prompt/context preparation, model and tool handling, and the UI’s major display areas. Some modules, including tools and provider, were not excerpted; their relationships are shown only where the source index or excerpts support them.

Main entry points: [`src/index.js`](https://github.com/codeandgyan/klaude-code/blob/main/src/index.js) (App entry), [`src/tui/index.js`](https://github.com/codeandgyan/klaude-code/blob/main/src/tui/index.js) (Terminal UI), [`src/tui/body/output.js`](https://github.com/codeandgyan/klaude-code/blob/main/src/tui/body/output.js) (Output pane), [`src/tui/footer/statusBar.js`](https://github.com/codeandgyan/klaude-code/blob/main/src/tui/footer/statusBar.js) (Status bar)
