Why it matters
- Zero-friction terminal AI access — no UI switching, no script writing; one command to ask GPT anything from the shell.
- Shell pipe composability makes AI part of Unix workflows — combine with grep, awk, git, and other tools for AI-enhanced automation.
- Minimal design means nothing to learn beyond
minion 'your prompt' — lowest possible onboarding cost.
- MIT license allows embedding in scripts, CI/CD pipelines, and developer tooling without licensing concerns.
Key capabilities
- Simple CLI:
minion 'prompt text' — one command to call OpenAI GPT.
- Pipe support: Compose with Unix pipes:
cat file.py | minion 'explain this code'.
- Shell scripting: Use in bash scripts for AI-powered automation.
- Model selection: Configure which GPT model to use via environment variables.
- OpenAI BYOK: Uses your own OpenAI API key.
- MIT license: Free to use in any context.
Technical notes
- Language: Node.js / TypeScript (check repository)
- License: MIT
- GitHub: github.com/mikaelvesavuori/minion
- Stars: 18
- Install:
npm install -g minion (check actual package name)
- Requirements: Node.js; OpenAI API key
Usage examples
# Basic prompt
minion "What is the difference between TCP and UDP?"
# Pipe a file for context
cat server.ts | minion "What does this code do?"
# Generate a commit message from diff
git diff --staged | minion "Write a concise git commit message"
# Explain an error
npm run build 2>&1 | minion "Why is this build failing?"
Ideal for
- Developers who want the simplest possible OpenAI CLI for quick terminal questions and shell script integration.
- Automation enthusiasts who want to add AI responses to bash scripts and pipelines.
- Developers prototyping AI-enhanced CLI tools who want a minimal reference implementation.
Not ideal for
- Multi-turn conversations — Minion is stateless; each call is independent.
- Access to non-chat OpenAI APIs (images, audio, embeddings) — use the official OpenAI CLI for full API access.
- Teams needing context-aware codebase assistance — use AIAssist or Aider for code-contextual help.
