N8n Node Configuration V2

n8n Node Configuration

Overview

This public intake copy packages plugins/antigravity-awesome-skills/skills/n8n-node-configuration from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.

n8n Node Configuration Expert guidance for operation-aware node configuration with property dependencies.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Configuration Philosophy, Core Concepts, get_node Detail Levels, Property Dependencies Deep Dive, Common Node Patterns, Operation-Specific Configuration.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• You need to configure an n8n node correctly for a specific resource and operation.
• The task involves required fields, property dependencies, or choosing the right get_node detail level.
• You are troubleshooting node setup rather than overall workflow architecture.
• Use when the request clearly matches the imported source intent: Operation-aware node configuration guidance. Use when configuring nodes, understanding property dependencies, determining required fields, choosing between get_node detail levels, or learning common configuration....
• Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
• Use when provenance needs to stay visible in the answer, PR, or review packet.

Operating Table

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. Identify node type and operation
2. Use get_node (standard detail is default)
3. Configure required fields
4. Validate configuration
5. If field unclear → getnode({mode: "searchproperties"})
6. Add optional fields as needed
7. Validate again

Example: Configuring HTTP Request

Step 1: Identify what you need

// Goal: POST JSON to API

Step 2: Get node info

const info = get_node({
  nodeType: "nodes-base.httpRequest"
});

// Returns: method, url, sendBody, body, authentication required/optional

Step 3: Minimal config

{
  "method": "POST",
  "url": "https://api.example.com/create",
  "authentication": "none"
}

Step 4: Validate

validate_node({
  nodeType: "nodes-base.httpRequest",
  config,
  profile: "runtime"
});
// → Error: "sendBody required for POST"

Step 5: Add required field

{
  "method": "POST",
  "url": "https://api.example.com/create",
  "authentication": "none",
  "sendBody": true
}

Step 6: Validate again

validate_node({...});
// → Error: "body required when sendBody=true"

Step 7: Complete configuration

{
  "method": "POST",
  "url": "https://api.example.com/create",
  "authentication": "none",
  "sendBody": true,
  "body": {
    "contentType": "json",
    "content": {
      "name": "={{$json.name}}",
      "email": "={{$json.email}}"
    }
  }
}

Step 8: Final validation

validate_node({...});
// → Valid! ✅

Imported: Summary

Configuration Strategy:

1. Start with get_node (standard detail is default)
2. Configure required fields for operation
3. Validate configuration
4. Search properties if stuck
5. Iterate until valid (avg 2-3 cycles)
6. Deploy with confidence

Key Principles:

• Operation-aware: Different operations = different requirements
• Progressive disclosure: Start minimal, add as needed
• Dependency-aware: Understand field visibility rules
• Validation-driven: Let validation guide configuration

Related Skills:

• n8n Validation Expert - Interpret validation errors
• n8n Expression Syntax - Configure expression fields
• n8n Workflow Patterns - Apply patterns with proper configuration

Imported: Configuration Philosophy

Progressive disclosure: Start minimal, add complexity as needed

Configuration best practices:

• get_node with detail: "standard" is the most used discovery pattern
• 56 seconds average between configuration edits
• Covers 95% of use cases with 1-2K tokens response

Key insight: Most configurations need only standard detail, not full schema!

Examples

Example 1: Ask for the upstream workflow directly

Use @n8n-node-configuration-v2 to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @n8n-node-configuration-v2 against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @n8n-node-configuration-v2 for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @n8n-node-configuration-v2 using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Start with get_node (standard detail)
• ~1-2K tokens response
• Covers 95% of configuration needs
• Default detail level
• Validate iteratively
• Configure → Validate → Fix → Repeat
• Average 2-3 iterations is normal

Imported Operating Notes

Imported: Best Practices

✅ Do

1. Start with get_node (standard detail)

   • ~1-2K tokens response
   • Covers 95% of configuration needs
   • Default detail level

2. Validate iteratively

   • Configure → Validate → Fix → Repeat
   • Average 2-3 iterations is normal
   • Read validation errors carefully

3. Use search_properties mode when stuck

   • If field seems missing, search for it
   • Understand what controls field visibility
   • get_node({mode: "search_properties", propertyQuery: "..."})

4. Respect operation context

   • Different operations = different requirements
   • Always check get_node when changing operation
   • Don't assume configs are transferable

5. Trust auto-sanitization

   • Operator structure fixed automatically
   • Don't manually add/remove singleValue
   • IF/Switch metadata added on save

❌ Don't

1. Jump to detail="full" immediately

   • Try standard detail first
   • Only escalate if needed
   • Full schema is 3-8K tokens

2. Configure blindly

   • Always validate before deploying
   • Understand why fields are required
   • Use search_properties for conditional fields

3. Copy configs without understanding

   • Different operations need different fields
   • Validate after copying
   • Adjust for new context

4. Manually fix auto-sanitization issues

   • Let auto-sanitization handle operator structure
   • Focus on business logic
   • Save and let system fix structure

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills/skills/n8n-node-configuration, fails to mention provenance, or does not use any copied source files at all. Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Check the external_source block first, then restate the provenance before continuing.

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task. Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Imported Reference Notes

Imported: Detailed References

For comprehensive guides on specific topics:

• DEPENDENCIES.md - Deep dive into property dependencies and displayOptions
• OPERATION_PATTERNS.md - Common configuration patterns by node type

Imported: Core Concepts

1. Operation-Aware Configuration

Not all fields are always required - it depends on operation!

Example: Slack node

// For operation='post'
{
  "resource": "message",
  "operation": "post",
  "channel": "#general",  // Required for post
  "text": "Hello!"        // Required for post
}

// For operation='update'
{
  "resource": "message",
  "operation": "update",
  "messageId": "123",     // Required for update (different!)
  "text": "Updated!"      // Required for update
  // channel NOT required for update
}

Key: Resource + operation determine which fields are required!

2. Property Dependencies

Fields appear/disappear based on other field values

Example: HTTP Request node

// When method='GET'
{
  "method": "GET",
  "url": "https://api.example.com"
  // sendBody not shown (GET doesn't have body)
}

// When method='POST'
{
  "method": "POST",
  "url": "https://api.example.com",
  "sendBody": true,       // Now visible!
  "body": {               // Required when sendBody=true
    "contentType": "json",
    "content": {...}
  }
}

Mechanism: displayOptions control field visibility

3. Progressive Discovery

Use the right detail level:

1. get_node({detail: "standard"}) - DEFAULT

   • Quick overview (~1-2K tokens)
   • Required fields + common options
   • Use first - covers 95% of needs

2. get_node({mode: "search_properties", propertyQuery: "..."}) (for finding specific fields)

   • Find properties by name
   • Use when looking for auth, body, headers, etc.

3. get_node({detail: "full"}) (complete schema)

   • All properties (~3-8K tokens)
   • Use only when standard detail is insufficient

Imported: get_node Detail Levels

Standard Detail (DEFAULT - Use This!)

✅ Starting configuration

get_node({
  nodeType: "nodes-base.slack"
});
// detail="standard" is the default

Returns (~1-2K tokens):

• Required fields
• Common options
• Operation list
• Metadata

Use: 95% of configuration needs

Full Detail (Use Sparingly)

✅ When standard isn't enough

get_node({
  nodeType: "nodes-base.slack",
  detail: "full"
});

Returns (~3-8K tokens):

• Complete schema
• All properties
• All nested options

Warning: Large response, use only when standard insufficient

Search Properties Mode

✅ Looking for specific field

get_node({
  nodeType: "nodes-base.httpRequest",
  mode: "search_properties",
  propertyQuery: "auth"
});

Use: Find authentication, headers, body fields, etc.

Imported: Property Dependencies Deep Dive

displayOptions Mechanism

Fields have visibility rules:

{
  "name": "body",
  "displayOptions": {
    "show": {
      "sendBody": [true],
      "method": ["POST", "PUT", "PATCH"]
    }
  }
}

Translation: "body" field shows when:

• sendBody = true AND
• method = POST, PUT, or PATCH

Common Dependency Patterns

Pattern 1: Boolean Toggle

Example: HTTP Request sendBody

// sendBody controls body visibility
{
  "sendBody": true   // → body field appears
}

Pattern 2: Operation Switch

Example: Slack resource/operation

// Different operations → different fields
{
  "resource": "message",
  "operation": "post"
  // → Shows: channel, text, attachments, etc.
}

{
  "resource": "message",
  "operation": "update"
  // → Shows: messageId, text (different fields!)
}

Pattern 3: Type Selection

Example: IF node conditions

{
  "type": "string",
  "operation": "contains"
  // → Shows: value1, value2
}

{
  "type": "boolean",
  "operation": "equals"
  // → Shows: value1, value2, different operators
}

Finding Property Dependencies

Use get_node with search_properties mode:

get_node({
  nodeType: "nodes-base.httpRequest",
  mode: "search_properties",
  propertyQuery: "body"
});

// Returns property paths matching "body" with descriptions

Or use full detail for complete schema:

get_node({
  nodeType: "nodes-base.httpRequest",
  detail: "full"
});

// Returns complete schema with displayOptions rules

Use this when: Validation fails and you don't understand why field is missing/required

Imported: Common Node Patterns

Pattern 1: Resource/Operation Nodes

Examples: Slack, Google Sheets, Airtable

Structure:

{
  "resource": "<entity>",      // What type of thing
  "operation": "<action>",     // What to do with it
  // ... operation-specific fields
}

How to configure:

1. Choose resource
2. Choose operation
3. Use get_node to see operation-specific requirements
4. Configure required fields

Pattern 2: HTTP-Based Nodes

Examples: HTTP Request, Webhook

Structure:

{
  "method": "<HTTP_METHOD>",
  "url": "<endpoint>",
  "authentication": "<type>",
  // ... method-specific fields
}

Dependencies:

• POST/PUT/PATCH → sendBody available
• sendBody=true → body required
• authentication != "none" → credentials required

Pattern 3: Database Nodes

Examples: Postgres, MySQL, MongoDB

Structure:

{
  "operation": "<query|insert|update|delete>",
  // ... operation-specific fields
}

Dependencies:

• operation="executeQuery" → query required
• operation="insert" → table + values required
• operation="update" → table + values + where required

Pattern 4: Conditional Logic Nodes

Examples: IF, Switch, Merge

Structure:

{
  "conditions": {
    "<type>": [
      {
        "operation": "<operator>",
        "value1": "...",
        "value2": "..."  // Only for binary operators
      }
    ]
  }
}

Dependencies:

• Binary operators (equals, contains, etc.) → value1 + value2
• Unary operators (isEmpty, isNotEmpty) → value1 only + singleValue: true

Imported: Operation-Specific Configuration

Slack Node Examples

Post Message

{
  "resource": "message",
  "operation": "post",
  "channel": "#general",      // Required
  "text": "Hello!",           // Required
  "attachments": [],          // Optional
  "blocks": []                // Optional
}

Update Message

{
  "resource": "message",
  "operation": "update",
  "messageId": "1234567890",  // Required (different from post!)
  "text": "Updated!",         // Required
  "channel": "#general"       // Optional (can be inferred)
}

Create Channel

{
  "resource": "channel",
  "operation": "create",
  "name": "new-channel",      // Required
  "isPrivate": false          // Optional
  // Note: text NOT required for this operation
}

HTTP Request Node Examples

GET Request

{
  "method": "GET",
  "url": "https://api.example.com/users",
  "authentication": "predefinedCredentialType",
  "nodeCredentialType": "httpHeaderAuth",
  "sendQuery": true,                    // Optional
  "queryParameters": {                  // Shows when sendQuery=true
    "parameters": [
      {
        "name": "limit",
        "value": "100"
      }
    ]
  }
}

POST with JSON

{
  "method": "POST",
  "url": "https://api.example.com/users",
  "authentication": "none",
  "sendBody": true,                     // Required for POST
  "body": {                             // Required when sendBody=true
    "contentType": "json",
    "content": {
      "name": "John Doe",
      "email": "john@example.com"
    }
  }
}

IF Node Examples

String Comparison (Binary)

{
  "conditions": {
    "string": [
      {
        "value1": "={{$json.status}}",
        "operation": "equals",
        "value2": "active"              // Binary: needs value2
      }
    ]
  }
}

Empty Check (Unary)

{
  "conditions": {
    "string": [
      {
        "value1": "={{$json.email}}",
        "operation": "isEmpty",
        // No value2 - unary operator
        "singleValue": true             // Auto-added by sanitization
      }
    ]
  }
}

Imported: Handling Conditional Requirements

Example: HTTP Request Body

Scenario: body field required, but only sometimes

Rule:

body is required when:
  - sendBody = true AND
  - method IN (POST, PUT, PATCH, DELETE)

How to discover:

// Option 1: Read validation error
validate_node({...});
// Error: "body required when sendBody=true"

// Option 2: Search for the property
get_node({
  nodeType: "nodes-base.httpRequest",
  mode: "search_properties",
  propertyQuery: "body"
});
// Shows: body property with displayOptions rules

// Option 3: Try minimal config and iterate
// Start without body, validation will tell you if needed

Example: IF Node singleValue

Scenario: singleValue property appears for unary operators

Rule:

singleValue should be true when:
  - operation IN (isEmpty, isNotEmpty, true, false)

Good news: Auto-sanitization fixes this!

Manual check:

get_node({
  nodeType: "nodes-base.if",
  detail: "full"
});
// Shows complete schema with operator-specific rules

Imported: Configuration Anti-Patterns

❌ Don't: Over-configure Upfront

Bad:

// Adding every possible field
{
  "method": "GET",
  "url": "...",
  "sendQuery": false,
  "sendHeaders": false,
  "sendBody": false,
  "timeout": 10000,
  "ignoreResponseCode": false,
  // ... 20 more optional fields
}

Good:

// Start minimal
{
  "method": "GET",
  "url": "...",
  "authentication": "none"
}
// Add fields only when needed

❌ Don't: Skip Validation

Bad:

// Configure and deploy without validating
const config = {...};
n8n_update_partial_workflow({...});  // YOLO

Good:

// Validate before deploying
const config = {...};
const result = validate_node({...});
if (result.valid) {
  n8n_update_partial_workflow({...});
}

❌ Don't: Ignore Operation Context

Bad:

// Same config for all Slack operations
{
  "resource": "message",
  "operation": "post",
  "channel": "#general",
  "text": "..."
}

// Then switching operation without updating config
{
  "resource": "message",
  "operation": "update",  // Changed
  "channel": "#general",  // Wrong field for update!
  "text": "..."
}

Good:

// Check requirements when changing operation
get_node({
  nodeType: "nodes-base.slack"
});
// See what update operation needs (messageId, not channel)
