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.

Workflow Routing

Request Pattern	Route To
n8n expression, curly braces, `$json`, variable syntax, expression error	`n8n-expression-syntax/SKILL.md`
n8n MCP, search nodes, validate workflow, manage credentials, audit instance, template library	`n8n-mcp-tools-expert/SKILL.md`
Workflow architecture, webhook pattern, batch processing, scheduled task, AI agent workflow, database ops	`n8n-workflow-patterns/SKILL.md`
Validate workflow, fix errors, auto-fix, validation profile, error severity	`n8n-validation-expert/SKILL.md`
Node configuration, node setup, operation parameters, property dependencies, detail levels	`n8n-node-configuration/SKILL.md`
Code node, JavaScript, n8n JS, return format, `$input`, built-in functions, SplitInBatches	`n8n-code-javascript/SKILL.md`
Python code node, n8n Python, stdlib only, Python limitations	`n8n-code-python/SKILL.md`
n8nac, n8n-as-code, code-first, workflow.ts, push, pull, verify, test, init, GitOps, decorator syntax, Class A/B error	`n8n-n8nac/SKILL.md`
code-mode, sandbox, token savings, tool consolidation, isolated-vm, lazy import, sibling tools, MCP runtime, LLM gotchas	`n8n-code-mode/SKILL.md`

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
