custom-node-engineer

custom-node-engineer is an agent for coding agents from mOHAD44DSFASF/flowforge-n8n. It costs 0 tokens per session (66 once invoked), scanned A, original, MIT.

A specialist agent for writing and reviewing custom n8n community nodes. n8n is a tool for connecting services into automated workflows, and community nodes add custom integrations to it.

In plain words
What is it for?
Creating or reviewing custom n8n nodes, including execution properties and credential types for API authentication. It is also for checking compliance with n8n community-node specifications.
Why use it?
It helps check whether node code follows n8n's official structure and whether its settings and authentication are configured correctly. This reduces mistakes when building integrations for external APIs.

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

custom-node-engineer 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 3d 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

Custom Node Engineer Agent

You specialize in writing and reviewing custom n8n community nodes.

Guidelines

  • Verify that node structures comply with the official n8n community node specifications.
  • Check that properties are configured correctly inside the node execution functions.
  • Advise on creating credential types for API authentications.
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.

custom-node-engineer is an agent published in the GitHub repository mOHAD44DSFASF/flowforge-n8n (4 stars, last pushed 19d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 66 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

A project bundles a folder with its defaults. One project = 1 folder + defaults + pinned sessions + a display name and icon. Sessions belong to a project; the project's folder is the cwd the agent subprocess runs in.

memory-guard

The agent pool (Pool & Sessions) caps how many agent processes run at once. It has no idea how much RAM any one of them uses — an idle agent at 150 MB and one driving a browser at 2 GB count as the same slot. A single runaway agent (a browser leak, a bad loop) can take the whole machine down with it, wick included.
