Ribbon is a cross-platform CLI alias tool designed for both humans and AI agents. Instead of retyping lengthy terminal commands, you define short phrases that map to full command strings — then call them at any time with minimal input. It works on Windows, Linux, and macOS.
The standout feature is its execution guard: a safety layer that blocks certain classes of commands from running when an AI agent is operating autonomously. This prevents accidental deletions, overwrites, or other aggressive actions during unattended sessions — a practical concern as agentic workflows become more common.
Ribbon is positioned as a CLI-native alternative to MCP (Model Context Protocol), focusing on token efficiency and stability. Because aliases compress verbose commands into short triggers, AI agents spend fewer tokens constructing and repeating long shell instructions. Custom alias sets let teams or individual users tailor the tool to their specific workflow and toolchain.
A good fit for developers who work with AI coding assistants, run automated pipelines, or simply want cleaner terminal workflows without reaching for a full shell scripting framework.
