# n8n-node-configuration-official

Keeps your agent from guessing n8n node parameters. It fetches the live shape first, so validation errors stop eating your build time.

## What it does

The skill sets a fixed order for any n8n node: search for the node, pick the `resource` and `operation` pair, then pull the exact parameter shape from `get_node_types` with discriminators attached. Skip the discriminators and you get the generic shape, missing operation-specific and required fields. That is where most "Cannot read property X" errors come from.

Resource-locator and load-options params get their own rule. Slack channels, spreadsheet tabs, database tables and columns, model lists — the skill says to resolve real values through `explore_node_resources` with a `credentialId` from `list_credentials`. An invented ID validates fine and points at nothing. One exception: `toolWorkflow.workflowId` has no search method, so it comes from `search_workflows` with `mode: 'id'`.

Reference files cover HTTP, webhooks, databases, comms, AI, triggers, Switch and Merge nodes. They hold gotchas and security rules rather than field names, and the skill is explicit that a reference example losing to `get_node_types` output means the tool wins. For mid-build tweaks there is `validate_node_config`, which runs the same Zod schema on isolated node configs. It does not replace `validate_workflow` as the publish gate.

## Requirements
- Works with: n8n, Slack, Gmail

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add n8n-io/skills --skill n8n-node-configuration-official -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/n8n-node-configuration-official/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/n8n-node-configuration-official/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add n8n-io/skills --skill n8n-node-configuration-official -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/n8n-node-configuration-official/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add n8n-io/skills --skill n8n-node-configuration-official -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/n8n-node-configuration-official/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install n8n-io/skills n8n-node-configuration-official
```

2. **Manually: put the files in place**
- File: `.github/skills/n8n-node-configuration-official/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add n8n-io/skills --skill n8n-node-configuration-official -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/n8n-io/skills --path skills/n8n-node-configuration-official
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/n8n-node-configuration-official/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add n8n-io/skills --skill n8n-node-configuration-official -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/n8n-io/skills/tree/HEAD/skills/n8n-node-configuration-official/SKILL.md

## When to use it
- build a node config against the current schema instead of memory
- surface required fields hidden behind conditional dependencies
- resolve a real Slack channel or spreadsheet tab ID
- check a single node without re-running the whole workflow
- clear stale parameters left over from a previous operation

## Example prompts
- Configure an HTTP Request node with auth and pagination, fetch the exact parameter shape first
- Add a Slack node that posts to a channel and resolve the real channel ID with explore_node_resources
- Validate this node config with validate_node_config, then run validate_workflow

# n8n Node Configuration

Each n8n node has its own parameter shape, often with conditional fields (parameter X only matters when parameter Y has value Z). Shapes evolve between versions. Guessing produces cryptic validation errors.

Don't guess, use the `get_node_types` tool.

## Non-negotiable

**Call `get_node_types` with discriminators (resource, operation, mode) before configuring a node.** Without discriminators you get the generic shape, missing operation-specific parameters and required fields. Build against the exact shape. Don't guess from memory.

**The live `get_node_types` output is the canonical parameter shape.** The references in this skill cover patterns, gotchas, security rules, and decision-making (when to use which operation, why credentials over text fields, engine retry caps, etc.) not parameter names or field structures. If a reference example conflicts with what `get_node_types` returns, trust the tool. Markdown drifts; the type def is generated from the live source.

**Never guess resource-locator or load-options values.** When `get_node_types` shows a param with `@searchListMethod` or `@loadOptionsMethod` (Slack channels, Sheets tabs/docs, DB tables/columns, model lists, labels), resolve the real value with `explore_node_resources` (pass a `credentialId` from `list_credentials`) and use a returned `value`. If you already know the exact ID, use it; if several match and intent is ambiguous, ask the user. An invented ID validates but points at nothing. Exception: `toolWorkflow.workflowId` has no search method, resolve it via `search_workflows` and use `mode: 'id'`.
