Recommended Workflow

For building any n8n workflow from scratch:

n8nac Bootstrap — Read n8n-n8nac/SKILL.md for code-first setup (init, GitOps sync)

Pattern — Read n8n-workflow-patterns/SKILL.md to select architecture

Discovery — Read n8n-mcp-tools-expert/SKILL.md for node search + tool usage

Config — Read n8n-node-configuration/SKILL.md for operation-aware setup

Expressions — Read n8n-expression-syntax/SKILL.md for data references

Validate — Read n8n-validation-expert/SKILL.md before deployment

Code Nodes — Read JS or Python skill only when Code nodes are needed

Code-Mode — Read n8n-code-mode/SKILL.md for sandbox optimization + LLM gotchas

Critical Gotchas

nodeType format: nodes-base.slack (search/validate) vs n8n-nodes-base.slack (workflow tools)

Webhook body: $json.body.name not $json.name

Code node return: Always [{json: {...}}] array

SplitInBatches: main[0] = once after done, main[1] = per batch
