TafySH

AI-Enhanced Terminal Shell with LLM-Powered Capabilities

TafySH wraps traditional shells (Bash/Zsh/Fish) with intelligent features:

• Natural language to command translation
• Multi-step autonomous task execution
• Multi-device orchestration (servers, robots, IoT)
• Strong security with human-in-the-loop
• Memory and context management

Installation

Requires uv for dependency management.

# Install uv (if not already installed)
curl -LsSf https://astral.sh/uv/install.sh | sh

# From PyPI (when released)
uv pip install tafysh

# From source
git clone https://github.com/TafyLabs/TafySH.git
cd TafySH
uv sync
uv pip install -e ".[dev]"

Quick Start

# Set your API key
export ANTHROPIC_API_KEY="your-key-here"

# Start TafySH
uv run tafysh

# Or with custom config
uv run tafysh --config ~/.tafysh/config.yaml

Usage

Inside the TafySH shell:

# Regular shell commands work normally
ls -la
git status

# AI-powered requests (prefix with 'ai ')
ai list all python files modified today
ai explain what this git command does: git rebase -i HEAD~3
ai help me set up a Python virtual environment

# Force shell execution (prefix with !)
!echo "force shell mode"

Configuration

Create ~/.tafysh/config.yaml:

llm:
  provider: anthropic
  model: claude-sonnet-4-20250514

shell:
  backend: zsh
  ai_prefix: "ai "

security:
  mode: normal
  require_confirmation: true

log_level: INFO

See examples/config.yaml for full options.

Development
