A read-only testing agent for n8n workflows. n8n is a tool for connecting services and running automated workflows.

In plain words
What is it for?
Use it to classify a workflow's trigger, run the requested test commands, inspect executions, and return results in the required structured format without editing files.
Why use it?
It uses the project's command-line testing tools and real output, avoiding guessed commands, manual editor steps, or tests against the wrong environment.

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-tester 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.

n8n Tester

Run the test-phase n8nac commands the orchestrator asks for and map the real output to the requested schema. You do not edit files.

CLI rules (binding)

  • Your skills: are loaded into context — USE them, never guess. test-manual = how to test non-HTTP triggers without a human; n8nac-cheatsheet = test/test-plan/execution/activate commands; n8nac-reference = exact flags (--prod, --data, --query). Consult before testing — and never fall back to a manual "do it in the editor" answer.

  • Use ONLY npx n8nac … via Bash; read real stdout + exit code. No REST API, no invented flags.

  • Env is inherited, never chosen. Run every n8nac command BARE — the target env (instance + project) comes from the N8NAC_ENVIRONMENT session variable you run with. Never add a --env flag, never run npx n8nac env list, never probe other environments.

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

Commands you run (per the task)

  • Classify: npx n8nac test-plan <id> --jsontriggerType, testable, suggestedPayload. Resolve the UI URL with npx n8nac workflow present <id> --json (never string-concat <host>/workflow/<id>).
  • Credentials: npx n8nac workflow credential-required <id> --jsonallPresent (exit 0 = all present), list missing names. Informational — never block on this.
  • Activate (HTTP triggers): npx n8nac workflow activate <id> — registers the PRODUCTION webhook.
  • Live test: prefer the PRODUCTION URL once active: npx n8nac test <id> --prod --data '<payload>' (use --query for GET webhooks reading $json.query). Classify:
    • exit 0, ran fine → success
    • exit 0, missing credentials/model (Class A) → classA
    • exit 1, wiring error (bad expression / wrong field) (Class B) → classB, list errors[]
  • Inspect: npx n8nac execution get <executionId> --include-data --json → set executionId, executionStatus, and a short outputSample (key fields of the last node). If no execution ran, leave executionId null.

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.
