Missing node notes in n8n
Why undocumented workflows become impossible to maintain over time
What is this issue?
Complex workflows without explanatory notes become 'tribal knowledge'—only the original creator understands them. When that person leaves or forgets, the workflow becomes a black box.
Nodes that need documentation:
•Complex Code nodes with business logic•Non-obvious branching decisions in IF/Switch•Workarounds for API quirks or bugs•Rate limiting or retry configurations
Why is this a problem?
Knowledge loss
When the creator leaves, understanding of the workflow goes with them.
Dangerous changes
Modifying undocumented logic risks breaking hidden dependencies.
Slow onboarding
New team members take much longer to understand workflows.
Debugging difficulty
Without context, it's hard to know if behavior is intentional or a bug.
How to fix it
- 1
Use sticky notes
Add Sticky Note nodes to explain complex sections of your workflow.
- 2
Document node purpose
Use the 'Notes' field in node settings to explain what each node does.
- 3
Explain business logic
Document WHY decisions are made, not just what the code does.
- 4
Create workflow README
Add a Sticky Note at the start summarizing the workflow's purpose and flow.
