# zot.sh

A lightweight, single-binary coding agent harness written in Go, with built-in providers for dozens of LLM services, a terminal UI, and support for extensions, themes and portable agent files.

zot.sh is a lightweight coding agent harness written in Go, distributed as one static binary with built-in providers for a large number of LLM services, including Anthropic, OpenAI, Kimi, DeepSeek, Google Gemini and Vertex, GitHub Copilot, Bedrock, Azure OpenAI, OpenRouter, Groq, Mistral, Moonshot and Ollama or other local models.

It ships built-in file and shell tools (read, write, edit, bash, glob), three run modes (interactive TUI, print and JSON), and a built-in Telegram bot. Extensions in any language can be added through a subprocess plus JSON-RPC interface, none installed by default. Standing project instructions come from AGENTS.md files, reusable instructions from SKILL.md files, and agents can be shared as portable files or pulled from a public GitHub repository.

It supports user and extension themes defined in JSON, and authenticates interactively through a browser-based login flow inside the TUI.
