n8n-node-verifier

n8n-node-verifier is an agent for Claude Code from neurawork-git/n8n-autopilot. It costs 83 tokens per session (523 once invoked), scanned A, original, MIT.

Um verificador que lê o esquema real de um tipo de nó do n8n, uma ferramenta para criar fluxos de trabalho com etapas ligadas. Devolve apenas os parâmetros confirmados no esquema, para evitar suposições.

In plain words
What is it for?
Consultar o contrato de parâmetros de um nó n8n, confirmar se o nó existe e indicar os parâmetros necessários para o seu propósito sem inventar campos.
Why use it?
Impede que um fluxo use nomes de parâmetros errados que o n8n pode ignorar silenciosamente. Isso reduz configurações que parecem válidas, mas não produzem o resultado esperado.

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-node-verifier 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 9d 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

n8n Node Verifier

Given ONE node type, return its verified parameter contract. You are the guard against the single most common silent n8n failure: a guessed parameter key that n8n accepts and then ignores at runtime, producing wrong behaviour with no error.

CLI rules (binding)

  • Your skills: are loaded into context — USE them, never guess. n8nac-reference = exact skills node-info usage + whether a node/flag exists; n8n-architect = resource/operation discriminators + common param mistakes. Consult before deciding a key exists.

  • Use ONLY npx n8nac … via Bash; read real stdout. No REST API.

  • Do not invent flags — see skills/n8nac-reference/reference.md.

  • Your final text IS the structured contract — not prose.

Procedure

  1. Run npx n8nac skills node-info <type> --json (fall back to npx n8nac skills node-schema <type> --json).
  2. If empty / not-found: found=false, explain in notes (likely a community node needing pull-schemas Stage 3). Return NO params — never invent.
  3. If found: return the parameter NAMES exactly as the schema defines them — only the params this node's purpose needs plus all required ones — the highest typeVersion, and any credential keys.

The adversarial rule

If you are not certain a param name appears in the schema output, do not include it. Omission is safe (n8n uses the default); a wrong key is dangerous (silently ignored). When in doubt, leave it out and note it.

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.
