n8n

n8n is a skill for Claude Code, Codex from RamithaW/openclaw-skill-n8n. It costs 62 tokens per session (897 once invoked), scanned A, original, MIT.

An add-on for building and managing n8n workflows, which connect apps and services to automate tasks. It works with workflow files, triggers, webhooks, expressions, executions, credentials, and n8n's public API.

In plain words
What is it for?
Use it to design, edit, import, export, debug, activate, list, run, and inspect n8n workflows and executions.
Why use it?
It helps turn an automation idea into a working workflow and makes failed runs easier to investigate. It can also reduce repeated manual work when managing workflows through the API.

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

n8n 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/n8n_api.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

n8n

Use this skill to reliably work with n8n as an automation engine: design workflows, generate/import/export workflow JSON, debug executions, and (when enabled) operate n8n via its public REST API.

Quick start (pick a path)

  1. Workflow design / changes (no API needed)
  • Clarify: trigger, inputs, outputs, schedule, error handling, idempotency.
  • Produce: either a workflow JSON export, or step-by-step UI instructions to build it.
  • For JSON structure + conventions: read {baseDir}/references/workflow-json.md.
  1. Operate n8n via REST API (recommended for repeatable ops)
  • Requires: N8N_BASE_URL + N8N_API_KEY.
  • Use the helper script: {baseDir}/scripts/n8n_api.py.
  • For auth/pagination details: read {baseDir}/references/n8n-api.md.

Workflow decision tree

  • If the user says “here’s my exported workflow JSON” → validate/modify JSON, return a new JSON export.
  • If the user says “build this in my n8n UI” → produce exact node-by-node build instructions.
  • If the user says “deploy / activate / list / run / inspect executions” → use the REST API helper script.
  • If the user says “webhook isn’t firing / workflow failed” → use the debugging checklist in {baseDir}/references/troubleshooting.md.

Core workflows

A) Create or update a workflow (JSON-first)

  1. Define the spec (minimal)
  • Trigger (Webhook/Cron/Manual)
  • Data sources + credentials
  • Transformations (expressions/code)
  • Side effects (write/send)
  • Error strategy (continue on fail vs stop, retries, alerting)
  1. Create/modify workflow JSON
  • Prefer small diffs.
  • Keep credentials references by name/id only; never embed secrets.
  • See {baseDir}/references/workflow-json.md.
  1. Import/update
  • UI: import JSON.
  • API: use {baseDir}/scripts/n8n_api.py (examples in references/n8n-api.md).
  1. Activate + verify
  • Activate workflow.
  • Run a controlled test; inspect execution + node outputs.

B) Debug an execution

  1. Confirm the trigger event occurred (webhook hit / schedule ran / manual start).
  2. Inspect the last execution and identify the failing node.
  3. Check common causes: missing credentials, expression errors, data shape mismatch, rate limits.
  4. Add observability: temporary Set/Code nodes to log key fields; consider an “Error Trigger” workflow.

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.
