About This Skill

Hobby workflows fail silently. Production workflows fail loudly, safely, and cheaply. This skill finds every gap between the two. Export your n8n workflow (menu → Download), paste the JSON, and get a graded production-readiness report (0–20) across 10 categories: 1. Error handling — error workflows, retries, failure notifications 2. Credential hygiene — hardcoded secrets and API keys flagged as CRITICAL 3. Idempotency — will a double-fired trigger send duplicate emails or charges? 4. Rate limits & batching — worst-case API cost estimated in dollars and calls 5. Webhook security — open webhooks that mutate data are flagged as CRITICAL 6. Timeouts & long-running paths 7. Observability — will you know it worked, not just that it failed? 8. Data handling — what PII leaves your tenant, and how to minimize it 9. Naming & maintainability — because 3am debugging is real 10. Cost traps — tight polling, oversized LLM context, infinite-loop risk What makes it different: - No vague advice. Every finding names the exact node, the exact setting, and the exact value — "Set retryOnFail=true, maxTries=3, waitBetweenTries=5000 on node 'Stripe - Create Charge'", never "add error handling". - Blast radius in business terms: findings tell you what actually goes wrong for your customers. - A 15-minute fix plan, ordered by damage prevented. - Static analysis only. The skill never executes your workflow or calls your services. Your JSON stays in your conversation. - Honest scoring: a solid workflow gets told it's solid. For freelancers and agencies delivering n8n automations, and for operators who built a workflow themselves and now depend on it. Not affiliated with n8n GmbH.
