Low-Code Automation Chains

Comparable to: n8n, Zapier, LangFlow

Key Concepts

Use the concepts below when they fit the task. Not every automation needs all of them.

• Each "node" in the automation is a small registered function with a single job
• Nodes chain via named queues using TriggerAction.Enqueue — easy to add, remove, or reorder steps
• HTTP triggers receive external webhooks (form submissions, payment events)
• Cron triggers start scheduled automations (daily digests, periodic syncs)
• PubSub broadcasts completion events for downstream listeners

Architecture

Automation 1: Form → Enrich → Store → Notify
  HTTP webhook → auto::enrich-lead → auto::store-lead → auto::notify-slack

Automation 2: Cron → Fetch → Transform → Store
  Cron (daily) → auto::fetch-rss → auto::transform-articles → auto::store-articles

Automation 3: Payment webhook → Validate → Update → Notify
  HTTP webhook → auto::validate-payment → auto::update-order → publish(payment.processed)

iii Primitives Used

Primitive	Purpose
registerWorker	Initialize the worker and connect to iii
registerFunction	Define each automation node
trigger({ ..., action: TriggerAction.Enqueue({ queue }) })	Chain nodes via named queues
trigger({ function_id: 'state::set', payload })	Persist data between nodes
trigger({ ..., action: TriggerAction.Void() })	Fire-and-forget notifications
registerTrigger({ type: 'http' })	Webhook entry points
registerTrigger({ type: 'cron' })	Scheduled automations

Reference Implementation

See ../references/low-code-automation.js for the full working example — three automation chains: form-to-Slack notification, RSS feed aggregation, and payment webhook processing.

Common Patterns

Code using this pattern commonly includes, when relevant:

• registerWorker(url, { workerName }) — worker initialization
• trigger({ function_id, payload, action: TriggerAction.Enqueue({ queue: 'automation' }) }) — node chaining
• Each node as its own registerFunction with auto:: prefix IDs
• Small, focused functions that do one thing (enrich, validate, store, notify)
• trigger({ function_id: 'state::set', payload: { scope, key, value } }) — persist between nodes
• const logger = new Logger() — structured logging per node

Adapting This Pattern

Use the adaptations below when they apply to the task.

• Add new automation chains by registering HTTP/cron triggers and chaining functions
• Each node should be independently testable — accept input, produce output
• Use separate queue names when different chains need different retry/concurrency settings
• For unreliable external services, wrap calls in try/catch and handle failures explicitly
• Keep node functions small — offload complex logic to dedicated functions

Pattern Boundaries

• If the task requires durable multi-step workflows with saga compensation and step tracking, prefer iii-workflow-orchestration.
• If the task involves multiple AI agents handing off work, prefer iii-agentic-backend.
• Stay with iii-low-code-automation when the primary concern is simple trigger-transform-action chains with minimal orchestration overhead.

When to Use

• Use this skill when the task is primarily about iii-low-code-automation in the iii engine.
• Triggers when the request directly asks for this pattern or an equivalent implementation.

Boundaries

• Never use this skill as a generic fallback for unrelated tasks.
• You must not apply this skill when a more specific iii skill is a better fit.
• Always verify environment and safety constraints before applying examples from this skill.
