---

Hitmos is a modern AI terminal assistant for developers, powered by OpenRouter. It brings a Claude Code–styled UX to your terminal — live markdown streaming, interactive model switching, project context injection, and Tab completion, all with zero latency overhead.

Key features:

• Streaming — responses stream token-by-token with live Markdown rendering via rich.
• Multi-model — switch between DeepSeek, Gemini, Claude, GPT-4o, Llama, and more with an interactive arrow-key picker.
• Project context — automatically injects your project files into the system prompt so the model can answer project-specific questions.
• Tab completion — /model <Tab> lists all available models; / completes all commands.
• Minimal UX — Claude Code–inspired welcome panel, ◆ status lines, clean > prompt.
• Fast — built on fasthttp-client with full async SSE streaming.
• Configurable — API key via env (OPEN_TOKEN, OPENROUTER_API_KEY) or ~/.hitmos/config.toml.

Requirements

Python 3.13+

Hitmos depends on:

• fasthttp-client — async HTTP transport with SSE streaming.
• rich — live Markdown rendering and styled console output.
• typer — CLI interface.
• orjson — fast JSON parsing.
• prompt-toolkit — async input with Tab completion (bundled with questionary).
• questionary — interactive model picker.
• pydantic-settings — config management.
