n8n: Skill for Claude Code

.agents/skills/node-add-oauth/SKILL.md

n8n:node-add-oauth is a skill for Claude Code from n8n-io/n8n. It costs 53 tokens per session (2,817 once invoked), scanned A, original, no licence file.

A tool for adding OAuth2 login support to an existing n8n node. OAuth2 is a standard way for an application to obtain permission to use another service without handling the user’s password.

In plain words
What is it for?
Use it when adding OAuth2 credentials to an existing n8n node or when the user asks for the node-add-oauth workflow.
Why use it?
It coordinates the credential file, node changes, tests, and command-line configuration needed for this kind of integration. This reduces the chance of updating only part of the node’s authentication setup.

Written for Claude Code: argument-hint in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is n8n-io/n8n's own configuration. It tells Claude Code how to work on n8n itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything n8n configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is pushd ../cli && pnpm typecheck && popd.

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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-add-oauth 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 8d 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
