Kiss — Development skill for Claude Code

KISS

A [ridiculously fast](#performance) terminal coding agent that keeps the interface simple and gives you control of the model, tools, sessions, and automation.

KISS has 44 built-in providers. These include OpenAI Codex (ChatGPT subscription), OpenAI API, Anthropic OAuth (Claude subscription), Anthropic API, Meta Muse, Cursor, Google, OpenRouter, Bedrock, Databricks, Snowflake, and GitHub Copilot.

You can also add OpenAI-compatible providers.

KISS is built in Rust and based on [Pi](https://github.com/earendil-works/pi).

KISS takes its name and product philosophy from [Keep It Simple, Stupid](https://en.wikipedia.org/wiki/KISS_principle). Why? Because I am stupid :)

Why KISS

• Start quickly. The native terminal interface reaches its first warm frame in about 5 ms.
• Keep your work. Resume, branch, compact, import, and export persistent sessions.
• Use your preferred model. Choose from more than 1,000 catalog models or add your own compatible provider.
• Automate long tasks. Run scheduled loops, measured autoresearch, parallel subagents, and dynamic workflows.
• Connect your tools. Use local and remote MCP servers, including OAuth servers.
• Build on it. Embed KISS through Rust, Python, TypeScript, WebAssembly, JSONL RPC, or WebSocket RPC.

KISS uses four focused tools by default: `read`, `write`, `edit`, and `bash`. Catppuccin Mocha is the default dark theme.

Install

macOS and Linux:

curl -LsSf https://raw.githubusercontent.com/racetozero/kiss/main/install.sh | sh

Windows, including ARM64:

powershell -ExecutionPolicy ByPass -c "irm https://raw.githubusercontent.com/racetozero/kiss/main/install.ps1 | iex"

The installer selects the correct release, verifies its SHA-256 checksum, and installs `kiss` in your user binary directory.

On Linux, if the glib
