Where n8n strains

Each one shows up when the same knowledge has to serve many people, many agents and more than one model.

Context lives in each workflow
Every workflow carries its own prompts and its own copy of the context, and they drift.
Knowledge approval
As of October 2026, n8n's public documentation does not describe a step that approves the knowledge an AI step uses.
No shared approved version
Each workflow's context is edited in place, with no approved version every workflow shares.
