Artificial Lifeform Intelligent Entity — terminal-native AI agent orchestrator

🤖 ALFIE CLI

Artificial Lifeform Intelligent Entity

A terminal-native AI agent orchestrator that plans, executes, monitors, and self-heals shell-level tasks using LLM reasoning.

---

What is ALFIE?

ALFIE bridges the gap between AI that talks and AI that works. Instead of just generating code or giving advice, ALFIE takes control of your terminal — planning multi-step shell workflows as directed acyclic graphs (DAGs), executing them with real process management, monitoring output in real time, and recovering from failures automatically.

Give it an intent in plain English — it breaks it into tasks, orders them by dependencies, runs them in parallel where possible, and reports back.

Key Features

• Natural Language → Execution Plans — Describe what you want; ALFIE's LLM planner generates a fully structured DAG of shell commands
• DAG Scheduler — Topological sorting, dependency tracking, parallel execution across a pane pool
• Multi-Model Support — Works with OpenAI, Anthropic, and Google models via the Vercel AI Gateway
• Interactive Chat — Multi-turn REPL with conversation memory and auto-execution of detected plans
• Watcher Engine — Real-time pane monitoring with state classification (idle / running / error / stuck / interactive)
• Safety Guard — Command blocklist, confirmation prompts for destructive operations, configurable safety policies
• OS-Aware — Detects Windows/Linux/macOS and generates platform-appropriate commands (PowerShell on Windows, bash on *nix)
• Session Memory — Persistent conversation history with per-session storage, trimming, and recall
• Dry Run Mode — Validate and safety-check plans without executing anything
• Rich Terminal UI — Beautiful tables, panels, spinners, and live-updating displays via Rich

Installation

pip install alfie-cli

Or install from source:

git clone https://github.com/p-typed/alfie-cli.git
cd alfie-cli
pip install -e ".[dev]"

Requirements

• Python 3.11+
• An API key for the Vercel AI Gateway (supports OpenAI, Anthropic, Google models)

Configuration

Set your API key as an environment variable:

# PowerShell (Windows)
$env:AI_GATEWAY_API_KEY = "your-api-key"

# Bash / Zsh (Linux / macOS)
export AI_GATEWAY_API_KEY="your-api-key"

Or create a .env file in your project root:

AI_GATEWAY_API_KEY=your-api-key

Quick Start

# Check ALFIE is installed
alfie version

# Verify system requirements
alfie doctor

# Run a task from natural language
alfie run "create a hello.txt file that says hello world"

# Run a multi-step task
alfie run "find all python files, count lines of code, and write a summary to report.txt"

# Use a specific model
alfie run "list system info" --model anthropic/claude-sonnet-4-20250514

# Dry-run to validate without executing
alfie run "delete temp files" --dry-run

---

Commands

alfie run

Execute a task from natural language or a JSON plan file.

# Natural language intent
alfie run "install dependencies and run tests"

# From a saved plan file
alfie run "deploy" --plan ./my-plan.json

# Dry-run mode — validate safety without executing
alfie run "rm -rf /tmp/old" --dry-run

# Specify a model
alfie run "gather system specs" --model google/gemini-2.5-flash

How it works:

1. Your intent is sent to the LLM planner
2. The planner returns a structured DAG of tasks with dependencies
3. The DAG scheduler topologically sorts tasks and executes them layer by layer
4. Results are displayed in a rich summary table

alfie chat

Interactive multi-turn conversation with auto-execution of plans.

# Start a new chat session
alfie chat

# Resume a previous session
alfie chat --session abc123

# Use a different model
alfie chat --model anthropic/claude-sonnet-4-20250514

Chat commands:

Command	Description
/clear	Clear conversation history
/info	Show session info
/exit	Quit (or press Ctrl+C)

When you ask ALFIE to do something in chat, it automatically generates and executes a plan — no extra confirmation needed.

alfie memory

Manage conversation memory across sessions.

# List all saved sessions
alfie memory list

# Show a specific session
alfie memory show <session-id>

# Delete a session
alfie memory delete <session-id>

# Clear all sessions
alfie memory clear

alfie watch

Monitor a running tmux session in real time.

# Watch a tmux session
alfie watch my-session

# Custom poll interval and timeout
alfie watch my-session --poll 5 --timeout 600

alfie doctor

Check system requirements and configuration.

alfie doctor

Shows status of Python version, tmux availability, API key configuration, and more.

alfie config

Display the current configuration as JSON.

alfie config

Other Commands

Command	Description
alfie version	Show ALFIE version
alfie status	Check status of current session
alfie kill	Emergency stop — kill all running tasks
alfie history	Show past sessions
alfie logs	Tail audit log

---

Supported Models

ALFIE works with any model available through the Vercel AI Gateway. Tested models include:

Provider	Model	Flag
OpenAI	GPT-4o Mini (default)	--model gpt-4o-mini
OpenAI	GPT-4o	--model gpt-4o
Anthropic	Claude Sonnet 4	--model anthropic/claude-sonnet-4-20250514
Google	Gemini 2.5 Pro	--model google/gemini-2.5-pro
Google	Gemini 2.5 Flash	--model google/gemini-2.5-flash
Google	Gemini 2.0 Flash	--model google/gemini-2.0-flash

---

Python API

ALFIE can be used as a library in your own Python code:

from alfie.planner import Planner
from alfie.scheduler.dag import TaskScheduler, PanePool, topological_sort
from alfie.models import Plan

# Generate a plan from natural language
planner = Planner(model="gpt-4o-mini")
plan = planner.generate("install numpy and run a quick benchmark")

# Inspect the plan
for task in plan.tasks:
    print(f"{task.id}: {task.cmd} (depends on: {task.depends_on})")

# Use the DAG scheduler
layers = topological_sort(plan.tasks)
print(f"Execution will proceed in {len(layers)} layers")

Async Support

import asyncio
from alfie.planner import Planner

async def main():
    planner = Planner(model="gpt-4o-mini")
    plan = await planner.agenerate("check disk usage and memory stats")
    for task in plan.tasks:
        print(f"{task.id}: {task.cmd}")

asyncio.run(main())

Memory Store

from alfie.memory.store import MemoryStore

# Create or resume a session
mem = MemoryStore(session_id="my-session")
mem.add("user", "Hello ALFIE")
mem.add("assistant", "Hello! How can I help?")

# Get messages for LLM context
messages = mem.get_context_messages(system_prompt="You are ALFIE.")

# List all sessions
for session in mem.list_sessions():
    print(session)
