n8n Workflow Development Skills

7 complementary skills for building production-ready n8n workflows. Sourced from czlonkowski/n8n-skills — 525+ nodes, 2,653+ templates analyzed, 10 production patterns.

Recommended Workflow

For building any n8n workflow from scratch:

1. n8nac Bootstrap — Read n8n-n8nac/SKILL.md for code-first setup (init, GitOps sync)
2. Pattern — Read n8n-workflow-patterns/SKILL.md to select architecture
3. Discovery — Read n8n-mcp-tools-expert/SKILL.md for node search + tool usage
4. Config — Read n8n-node-configuration/SKILL.md for operation-aware setup
5. Expressions — Read n8n-expression-syntax/SKILL.md for data references
6. Validate — Read n8n-validation-expert/SKILL.md before deployment
7. Code Nodes — Read JS or Python skill only when Code nodes are needed
8. 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
