python-agent-engine from kennyzir/7deer_skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add kennyzir/7deer_skills/python-agent-engine@git:20260116.d3a8dc0Pins git:20260116.d3a8dc0 in mdr.lock. Pin the fingerprint instead.

A production-ready Python AI Agent engine using LangChain. Supports ReAct pattern, tool calling, and thinking process tracking.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Python Agent Engine
A plug-and-play AI Agent core for Python applications. It handles the complexity of LLM interaction, tool calling loops, and context management.
## Features
- **ReAct Loop**: Automatically handles "Reasoning -> Tool Call -> Result -> Answer" process.
- **Thinking Process**: Returns structured "Thinking Steps" for UI visualization.
- **Model Agnostic**: Works with OpenAI, DeepSeek, or any OpenAI-compatible API.
## Installation
1. Copy `resources/agent_engine.py` to your project (e.g., `src/core/agent_engine.py`).
2. Install dependencies:
```bash
pip install langchain-core langchain-openai python-dotenv
```
3. Set Environment Variables in your `.env` file:
```ini
OPENAI_API_KEY=sk-...
# Optional:
OPENAI_BASE_URL=https://api.openai.com/v1
```
## Usage Example
```python
import asyncio
from langchain_core.tools import tool
from core.agent_engine import AgentEngine
# 1. Define Tools
@tool
def calculator(expression: str) -> str:
"""Calculates a math expression."""
return str(eval(expression))
# 2. Initialize Agent
agent = AgentEngine(
tools=[calculator],
system_prompt="You are a helpful math assistant.",

How to install
mdr add kennyzir/7deer_skills/python-agent-engine@sha256:f196fcca75e02b46The line at the top of this page pins the label git:20260116.d3a8dc0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
