The .0n Standard
The universal configuration format for AI orchestration.
What is .0n?
Just as .git revolutionized version control and .env standardized environment configuration, .0n establishes the universal standard for AI orchestration configuration.
~/.0n/
├── config.json # Global settings
├── connections/ # Service credentials
│ ├── stripe.0n
│ ├── slack.0n
│ └── openai.0n
├── workflows/ # Automation definitions
│ └── invoice-notify.0n
├── snapshots/ # System state captures
│ └── crm-setup.0n
├── history/ # Execution logs
└── cache/ # Response cache
Every .0n file has a standard header:
{
"$0n": {
"type": "connection",
"version": "1.0.0",
"name": "Production Stripe"
},
"service": "stripe",
"auth": {
"type": "api_key",
"credentials": { "api_key": "{{env.STRIPE_SECRET_KEY}}" }
}
}
The philosophy: "Turn it on. It just works."
Why .0n?
| Problem | .0n Solution |
|---|---|
| Every orchestrator invents its own config format | One standard format for all |
| Credentials scattered across env files, JSON, YAML | ~/.0n/connections/ — one place |
| Workflows trapped in proprietary tools | Portable .0n workflow files |
| No execution history standard | ~/.0n/history/ — JSONL by date |
| System configs can't be shared | Shareable snapshots with .0n format |
File Types
| Type | Purpose | Example |
|---|---|---|
connection |
Service credentials | stripe.0n |
workflow |
Multi-step automations | invoice-notify.0n |
snapshot |
System state capture | crm-setup.0n |
execution |
Task run history | 2026-02-06.jsonl |
config |
Global settings | config.json |
Schemas
JSON Schemas for validation:
- schemas/config.json — Global configuration
- schemas/connection.json — Service connections
- schemas/workflow.json — Workflow definitions
- schemas/snapshot.json — System snapshots
Examples
Working examples of each file type:
- examples/config.0n — Global config with Anthropic provider
- examples/stripe.0n — Stripe connection with env var credentials
- examples/invoice-notify.0n — 5-step workflow: find customer, create invoice, add line item, send, notify Slack
- examples/crm-setup.0n — Full CRM snapshot with pipeline, 10 tags, custom fields, custom values, 3 workflows, email templates
CLI
Initialize, validate, and test .0n files from the command line.
Install
npm install -g 0n-spec
Commands
# Initialize ~/.0n/ directory
0n init
# Validate a .0n file
0n validate my-workflow.0n
# Validate entire directory
0n validate ~/.0n/
# Run conformance tests against examples
0n test
Library
Use programmatically in Node.js:
const { validate, parse, create, init, list, save } = require('0n-spec');
// Validate a file
const result = validate('my-workflow.0n');
// { valid: true, type: 'workflow', version: '1.0.0', errors: [], warnings: [] }
// Parse a .0n file
const workflow = parse('~/.0n/workflows/invoice-notify.0n');
// { type: 'workflow', name: 'Invoice and Notify', data: {...} }
// Create a new .0n object
const connection = create('connection', {
name: 'My Stripe',
service: 'stripe',
authType: 'api_key',
credentials: { api_key: '{{env.STRIPE_KEY}}' },
});
// Initialize ~/.0n/ directory
init();
// List all connections
const connections = list('connection');
// Save to file
save(connection, '~/.0n/connections/stripe.0n');
Template Syntax
The .0n standard uses double-brace templates:
| Syntax | Description |
|---|---|
{{inputs.name}} |
Reference input parameter |
{{step_id.output.field}} |
Reference step output |
{{env.VAR_NAME}} |
Reference environment variable |
{{now}} |
Current ISO timestamp |
{{uuid}} |
Generate UUID |
Implementations
| Product | Description | Status |
|---|---|---|
| 0nMCP | Universal AI API Orchestrator — 850 tools, 53 services | Production |
Building a .0n Implementation
- Use
~/.0n/as the config directory - Support the
$0nheader in all files - Validate against the JSON schemas
- Pass conformance tests:
npx 0n-spec test
