design-n8n-agent-workflow

design-n8n-agent-workflow is a skill for Claude Code, Codex from gaelic-ghost/socket. It costs 37 tokens per session (422 once invoked), scanned A, original, Apache-2.0.

A set of guidelines for designing safe n8n workflows, where n8n is a visual tool for connecting triggers, data, services, and actions.

In plain words
What is it for?
It is for planning workflow routes, credentials, retries, duplicate protection, local-model checks, drafts, approvals, and failure handling.
Why use it?
It helps prevent accidental writes, duplicated events, exposed secrets, unreliable model results, and unclear recovery steps when workflows include AI.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

design-n8n-agent-workflow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Design n8n Agent Workflow

Use this skill when n8n is the right visual, trigger-driven integration surface. It does not turn n8n into a default durable multi-agent runtime.

Source Check

Workflow

  1. Map trigger, deterministic transforms/routes, external reads, model step, draft output, and any external write separately.
  2. Select credentials/storage ownership, webhook exposure, retry policy, idempotency key, concurrency limit, and failed-run record before connecting an AI node.
  3. Treat the local model as one bounded node: prove structured output, tool compatibility when used, no-call behavior, malformed result recovery, and the exact model/server combination before exposing a write node.
  4. Keep source data minimised and trace/log retention explicit. Do not put secrets in workflow exports or prompts.
  5. Leave write nodes disabled or draft-only until auto-with-escalation names the recipient, action, payload evidence, and approval event.
  6. Export a testable workflow fixture and verify happy path, duplicate event, failed model response, credential failure, rejected approval, and recovery.

Output Shape

Return trigger, node graph, credentials, idempotency/retry behavior, model contract, draft artifact, approval event, and recovery evidence.

Guardrails

  • Prefer deterministic n8n nodes over agent planning whenever the route is known.
  • Do not expose a self-hosted instance publicly without an explicit deployment and authentication decision.
  • Do not claim a local model is reliable for tool use without a capability gate.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
