Personal AGI Operating Core

🌌 MONAD

Personal AGI Operating Core

🇨🇳 简体中文 (Chinese) • How It Works • Installation • Architecture

MONAD is not a chatbot or a simple tool-matcher. It is a self-learning, objective-driven autonomous rational agent core.

Unlike traditional agents that rely on a predefined, hardcoded set of tools, MONAD acts like a rational entity with basic "instincts". It has no memory and no pre-loaded knowledge of how to perform specific tasks (like checking the weather or searching the web).

Instead, it autonomously learns how to complete your tasks by writing and executing Python code on the fly, and then saving those successful experiences as reusable skills.

🧠 Core Philosophy

• File System as Database: The system itself has no memory of past sessions. It persists all learned information (axioms, environment knowledge, learned skills, user context, and experiences) directly to local Markdown files. No vector databases, no RAG, zero external dependencies.
• Absolute Rationality: MONAD follows a strict reasoning loop (Analyze → Self-check → Learn → Execute → Reflect) to accomplish goals logically.
• Self-Learning & Self-Evolving: Instead of shipping with 100 tools, MONAD ships with only 4 basic instincts (hands 🤲, voice 🗣️, eyes 👁️, dialogue 💬). It learns everything else by generating code.
• LLM as a Command Executor: The LLM's own training data is disregarded. All factual information must be retrieved from the real world via code execution or web perception.
• Stateless Message Management: Every user request starts with a fresh, clean message context. MONAD doesn't rely on LLM Chat History; instead, it persists vital information via reflection loops. This ensures reasoning purity and prevents hallucination buildup from long conversations.
• Search First, Ask Later: When stuck during execution (errors, missing packages, unfamiliar tools), MONAD's first instinct is to search the web via web_fetch, never to guess. But if the user's intent is unclear, MONAD asks the user first. In short: unclear query → ask user; execution problem → search first.
• URL-First Principle: When the user provides a specific URL or domain (e.g., "Analyze kexue.fm"), MONAD must directly access that URL first, not detour through a search engine. Search engines are a fallback, not the default when a target is already known.
• Experience Staging & Hygiene: Experiences don't go directly into long-term memory. New experiences first land in a staging area (pending.jsonl). Only when the same tag pattern recurs ≥3 times is the best example promoted to the permanent experience file — a frequency-based deduplication inspired by how humans consolidate short-term memory into long-term memory. Failed experiences are tagged [FAILED] and never promoted, preventing "experience pollution."
• Tag-Based Experience Retrieval: Experiences are tagged during reflection. At reasoning time, MONAD scores each experience by relevance × 2 + recency (not semantic embeddings, just keyword overlap + timestamp), picks the top entries, and always includes the 3 most recent as fallback. Simple, fast, zero infrastructure.
• Anti-Hallucination Verification: LLMs sometimes claim "I created the skill" without actually writing any files. MONAD defends against this at two levels: (1) Post-Action Verification — after actions that should create files, the system checks the filesystem and appends verification results to the LLM's observation; (2) Hollow Answer Guard — if the LLM tries to deliver a final answer claiming creation/saving but never executed a write action, the answer is rejected and the LLM is forced to actually do the work.
• Skill Deduplication (Reuse First): Before creating a new skill, the system prompts the LLM to check existing skills and prefer modifying them. The SkillBuilder module independently evaluates all existing skills and supports three actions: skip, update (preferred), or create — preventing the skill library from growing duplicate entries.

⚡ Basic Capabilities ("Instincts")

MONAD comes with only four built-in capabilities:

Capability	Metaphor	Description
🐍 python_exec	Hands 🤲	Evaluate arbitrary Python code. Process data, call APIs, read/write files, install libraries—learn to do anything.
💻 shell	Voice 🗣️	Execute shell commands on the host operating system.
👁️ web_fetch	Eyes 👁️	Perceive the internet directly. Fetch web pages with 3 modes: fast (HTTP), stealth (anti-bot), browser (JS render). Powered by Scrapling.
🙋 ask_user	Dialogue 💬	Ask the user for clarification when it truly cannot proceed independently.

📂 Knowledge Architecture

MONAD uses Categorized Memory instead of semantic retrieval (RAG).

⚙️ How It Works

When you give MONAD an objective (e.g., "What is the weather in Hangzhou today?"):

1. Analyze & Self-Check: Understand intent and check the local knowledge base for existing skills.
2. Learn & Research (The "Search First" Principle): If the task is unknown or an error occurs, MONAD uses web_fetch to research documentation, API usage, or solutions. This is the "Learning" phase where it acquires the "how-to" knowledge before acting.
3. Execute & Observe: MONAD writes and executes Python code or shell commands via python_exec. It treats the output as "Observations" to verify success or identify new obstacles.
4. Reflect & Persist: After a successful execution, the Reflection module summarizes the experience with tags. The SkillBuilder evaluates if the logic should be abstracted into a permanent skill — checking existing skills first to avoid duplication.
5. Verify & Answer: Before delivering the final answer, the system verifies that claimed actions actually happened (files exist, skills were written). The answer is based on real-world data verified through execution.

💡 Deep Dive: Why Stateless?

MONAD intentionally discards traditional "Chat History" in favor of a Stateless Design, where every task starts with a clean context and persists only vital information via the file system.

• Mitigating Hallucination: Long-running chat histories eventually lead to context pollution and attention decay. By resetting the context per task, we force the LLM to reason in a pure, noise-free environment.
• Physical Memory: Unlike black-box model caches, MONAD's memory consists of human-readable Markdown files. This is a deliberate step towards Personal Data Sovereignty.
• Task Atomicity: Every objective becomes an independent, reproducible unit of execution.
• The Future of Agents: We believe the evolution of Agents will shift from "simulating conversation" to "simulating rational execution." Maintaining a living "State Whiteboard" via reflection loops is far more aligned with the essence of AGI than endlessly stacking chat logs.

🚀 Installation

1. Install via pip (Recommended)

pip install monad-core

Alternatively, install from source:

git clone https://github.com/hscspring/Monad.git
cd Monad
pip install -e .

2. Configure your LLM On your first run, MONAD will initialize its workspace in ~/.monad/. Update ~/.monad/.env with your LLM Base URL, API Key, and Model name.

Note: If you don't configure this manually, MONAD will guide you through an interactive setup with connectivity validation on your first launch.
