description	Edit, analyze, and create Node-RED flows by working with flows.json files, understanding node types, and applying Node-RED best practices. Use when the user mentions Node-RED, flows.json, flow development, or needs to modify Node-RED configurations.

Node-RED Flow Development

This skill provides comprehensive support for Node-RED development, including flow creation, modification, validation, and deployment through the Admin API.

When to Use This Skill

Use this skill when:

• Creating or modifying Node-RED flows (flows.json files)
• Building MQTT, HTTP API, or data pipeline integrations
• Debugging or validating flow configurations
• Working with function nodes and context storage
• Deploying flows via the Node-RED Admin API
• Converting requirements into Node-RED flow implementations

Scripts (scripts/)

Execute these Python scripts for common Node-RED operations:

• generate_uuid.py - Generate valid Node-RED node IDs

  python scripts/generate_uuid.py [count]
  

• validate_flow.py - Validate flow JSON structure and wire connections

  python scripts/validate_flow.py <flow.json>
  

• wire_nodes.py - Connect nodes programmatically

  python scripts/wire_nodes.py <flow.json> <source_id> <target_id> [output_port]
  

• create_flow_template.py - Generate boilerplate flows

  python scripts/create_flow_template.py <mqtt|http-api|data-pipeline|error-handler> [output.json]
