Standalone AI Agent Executor · Apache-2.0 · Windows · Linux · macOS

Run SKILL.md agents and YAML workflows against any enterprise data source — no cloud, no platform, just a single binary.

What is OE Runtime?

A standalone binary that reads a declarative agent file, connects to your enterprise data sources, and runs an AI workflow — locally or as an HTTP API server. No Python. No LangChain. No Docker required.

Supports two agent formats:

• SKILL.md — portable Markdown-based agent skills (agentskills.io spec). The same file runs on Claude, Cursor, Windsurf, or OE Runtime unchanged.
• agent.yaml — OE-native YAML format with inline steps, chains, and scheduling.

Quick Start

npx -y @openenthrium/oe-runtime ./skills/hello-world

-y is required — without it npx blocks waiting for keyboard input and the agent never runs.

OE Runtime automatically finds oe-config.json in the agent's folder or your current directory.

Running SKILL.md Agents

A SKILL.md skill is a Markdown file — frontmatter carries the metadata, ## Step headings define the workflow. Connector wiring stays in agent.yaml + oe-config.json, keeping the skill itself portable.

Folder structure:

my-skill/
├── SKILL.md          ← the portable skill (agentskills.io format)
├── agent.yaml        ← wires SKILL.md to your connectors
└── oe-config.json    ← LLM key + connector credentials

agent.yaml:

name: SQL Database Analyst
description: Query a database and summarise results in plain English
connectors:
  - connection_name: My Database
    connection_type: postgresql
skills:
  - path: ./SKILL.md
    trigger_type: auto

SKILL.md:

---
name: SQL Database Analyst
version: 1.0.0
description: Query a database and summarise results in plain English
author: Your Name

---

You are a data analyst. Use the available database tools to answer the user's question clearly.

## Step 1: Explore Schema
List the available tables and understand the data structure.

## Step 2: Query
Run the most relevant query for the user's request.

## Step 3: Report
Summarise the findings in plain English with key numbers highlighted.

oe-config.json:

{
  "llm": { "provider": "openai", "apiKey": "sk-...", "model": "gpt-4o" },
  "connectors": [
    {
      "connection_name": "My Database",
      "connection_type": "postgresql",
      "host": "localhost",
      "port": 5432,
      "database": "mydb",
      "user": "postgres",
      "password": "YOUR_DB_PASSWORD"
    }
  ]
}

Run it:

npx -y @openenthrium/oe-runtime ./my-skill

Pass the folder — OE Runtime resolves agent.yaml inside it automatically.

HTTP Server Mode

Enable server mode in oe-config.json:

{
  "llm": { "provider": "openai", "apiKey": "sk-...", "model": "gpt-4o" },
  "server": { "enabled": true, "port": 3333, "apiKey": "your-secret" },
  "connectors": [ ... ]
}

Start:

npx -y @openenthrium/oe-runtime --serve --config oe-config.json

Endpoints:

Method	Path	Description
GET	/health	Liveness check
POST	/run	Run an agent from inline YAML
POST	/run-file	Run an agent from a file path on disk
POST	/approve-chain	Approve or reject a pending manual chain

# Run a SKILL.md agent via HTTP
curl -X POST http://localhost:3333/run-file \
  -H "x-api-key: your-secret" \
  -H "Content-Type: application/json" \
  -d '{"file": "/path/to/my-skill/agent.yaml", "params": {}, "input": "run"}'

Embed in Node.js (SDK)

npm install @openenthrium/oe-runtime-sdk

const { runAgent } = require("@openenthrium/oe-runtime-sdk");

const result = await runAgent("./my-skill/agent.yaml", "./oe-config.json");
console.log(result.output);

→ npm package
