Nathan Development Standards

Standards and patterns for developing within the Nathan project - an n8n-Jira agent automation system.

When to Use

Invoke this skill when:

Creating or modifying n8n workflow JSON files
Writing Python code for the Nathan helpers or templating modules
Designing webhook command contracts
Building workflow registry configurations
Implementing spec-driven features via agent-os

Project Architecture

Nathan follows a layered architecture:

External Service (Jira) <-- n8n Workflows <-- Python Agent Service
                             (credentials)      (webhook calls)

Core Principle: n8n owns all external credentials. Python services call n8n webhooks with shared secret authentication.

n8n Workflow Standards

For detailed workflow patterns, load references/n8n-workflow-patterns.md.

Standard Workflow Structure

Every webhook workflow must follow this pattern:

Webhook --> Validate Secret --> Operation --> Respond to Webhook
               |                   |              |
               v                   v              v
           Unauthorized       Error Response   Success Response
           Response (401)     (500)            (200)
