        description: `Updates workflows using surgical diff operations instead of full replacement. Supports 18 operation types for precise modifications. Operations are validated and applied atomically by default - all succeed or none are applied.

## Available Operations:

### Node Operations (7 types):
- **addNode**: Add a new node with name, type, and position (required)
- **removeNode**: Remove a node by ID or name
- **updateNode**: Update node properties using dot notation (e.g., 'parameters.url')
- **patchNodeField**: Surgically edit string fields using find/replace patches. Strict mode: errors if find string not found, errors if multiple matches (ambiguity) unless replaceAll is set. Supports replaceAll and regex flags.
- **moveNode**: Change node position [x, y]
- **enableNode**: Enable a disabled node
- **disableNode**: Disable an active node

### Connection Operations (5 types):
- **addConnection**: Connect nodes (source→target). Supports smart parameters: branch="true"/"false" for IF nodes, case=N for Switch nodes.
- **removeConnection**: Remove connection between nodes (supports ignoreErrors flag)
- **rewireConnection**: Change connection target from one node to another. Supports smart parameters.
- **cleanStaleConnections**: Auto-remove all connections referencing non-existent nodes
- **replaceConnections**: Replace entire connections object

### Metadata Operations (4 types):
- **updateSettings**: Modify workflow settings
- **updateName**: Rename the workflow
- **addTag**: Add a workflow tag
- **removeTag**: Remove a workflow tag

### Workflow Activation Operations (2 types):
- **activateWorkflow**: Activate the workflow to enable automatic execution via triggers
- **deactivateWorkflow**: Deactivate the workflow to prevent automatic execution

### Project Management Operations (1 type):
- **transferWorkflow**: Transfer the workflow to a different project. Requires \`destinationProjectId\`. Enterprise/cloud feature.

## Smart Parameters for Multi-Output Nodes

For **IF nodes**, use semantic 'branch' parameter instead of technical sourceIndex:
- **branch="true"**: Routes to true branch (sourceIndex=0)
- **branch="false"**: Routes to false branch (sourceIndex=1)

For **Switch nodes**, use semantic 'case' parameter:
- **case=0**: First output
- **case=1**: Second output
- **case=N**: Nth output

Works with addConnection and rewireConnection operations. Explicit sourceIndex overrides smart parameters.

## AI Connection Support

Full support for all 8 AI connection types used in n8n AI workflows:

**Connection Types**:
- **ai_languageModel**: Connect language models (OpenAI, Anthropic, Google Gemini) to AI Agents
- **ai_tool**: Connect tools (HTTP Request Tool, Code Tool, etc.) to AI Agents
- **ai_memory**: Connect memory systems (Window Buffer, Conversation Summary) to AI Agents
- **ai_outputParser**: Connect output parsers (Structured, JSON) to AI Agents
- **ai_embedding**: Connect embedding models to Vector Stores
- **ai_vectorStore**: Connect vector stores to Vector Store Tools
- **ai_document**: Connect document loaders to Vector Stores
- **ai_textSplitter**: Connect text splitters to document processing chains

**AI Connection Examples**:
- Single connection: \`{type: "addConnection", source: "OpenAI", target: "AI Agent", sourceOutput: "ai_languageModel"}\`
- Fallback model: Use targetIndex (0=primary, 1=fallback) for dual language model setup
- Multiple tools: Batch multiple \`sourceOutput: "ai_tool"\` connections to one AI Agent
- Vector retrieval: Chain ai_embedding → ai_vectorStore → ai_tool → AI Agent

**Important Notes**:
- **AI nodes do NOT require main connections**: Nodes like OpenAI Chat Model, Postgres Chat Memory, Embeddings OpenAI, and Supabase Vector Store use AI-specific connection types exclusively. They should ONLY have connections like \`ai_languageModel\`, \`ai_memory\`, \`ai_embedding\`, or \`ai_tool\` - NOT \`main\` connections.

**Best Practices**:
- Always specify \`sourceOutput\` for AI connections (defaults to "main" if omitted)
- Connect language model BEFORE creating/enabling AI Agent (validation requirement)
- Use atomic mode (default) when setting up AI workflows to ensure complete configuration
- Validate AI workflows after changes with \`n8n_validate_workflow\` tool

## Cleanup & Recovery Features

### Automatic Cleanup
The **cleanStaleConnections** operation automatically removes broken connection references after node renames/deletions. Essential for workflow recovery.

### Best-Effort Mode
Set **continueOnError: true** to apply valid operations even if some fail. Returns detailed results showing which operations succeeded/failed. Perfect for bulk cleanup operations.

### Graceful Error Handling
Add **ignoreErrors: true** to removeConnection operations to prevent failures when connections don't exist.

## Auto-Sanitization System

### What Gets Auto-Fixed
When ANY workflow update is made, ALL nodes in the workflow are automatically sanitized to ensure complete metadata and correct structure:

1. **Operator Structure Fixes**:
   - Binary operators (equals, contains, greaterThan, etc.) automatically have \`singleValue\` removed
   - Unary operators (empty, notEmpty, true, false) automatically get \`singleValue: true\` added
   - Invalid operator structures (e.g., \`{type: "notEmpty"}\`) are corrected to \`{type: "object", operation: "notEmpty"}\`

2. **Missing Metadata Added**:
   - IF nodes with conditions get complete \`conditions.options\` structure if missing
   - Switch nodes with conditions get complete \`conditions.options\` for all rules
   - Required fields: \`{version: 2, leftValue: "", caseSensitive: true, typeValidation: "strict"}\`

### Sanitization Scope
- Runs on **ALL nodes** in the workflow, not just modified ones
- Triggered by ANY update operation (addNode, updateNode, addConnection, etc.)
- Prevents workflow corruption that would make UI unrenderable

### Limitations
Auto-sanitization CANNOT fix:
- Broken connections (connections referencing non-existent nodes) - use \`cleanStaleConnections\`
- Branch count mismatches (e.g., Switch with 3 rules but only 2 outputs) - requires manual connection fixes
- Workflows in paradoxical corrupt states (API returns corrupt data, API rejects updates) - must recreate workflow

### Recovery Guidance
If validation still fails after auto-sanitization:
1. Check error details for specific issues
2. Use \`validate_workflow\` to see all validation errors
3. For connection issues, use \`cleanStaleConnections\` operation
4. For branch mismatches, add missing output connections
5. For paradoxical corrupted workflows, create new workflow and migrate nodes

## Automatic Connection Reference Updates

When you rename a node using **updateNode**, all connection references throughout the workflow are automatically updated. Both the connection source keys and target references are updated for all connection types (main, error, ai_tool, ai_languageModel, ai_memory, etc.) and all branch configurations (IF node branches, Switch node cases, error outputs).

### Basic Example
\`\`\`javascript
// Rename a node - connections update automatically
n8n_update_partial_workflow({
  id: "wf_123",
  operations: [{
    type: "updateNode",
    nodeId: "node_abc",
    updates: { name: "Data Processor" }
  }]
});
// All incoming and outgoing connections now reference "Data Processor"
\`\`\`

### Multi-Output Node Example
\`\`\`javascript
// Rename nodes in a branching workflow
n8n_update_partial_workflow({
  id: "workflow_id",
  operations: [
    {
      type: "updateNode",
      nodeId: "if_node_id",
      updates: { name: "Value Checker" }
    },
    {
      type: "updateNode",
      nodeId: "error_node_id",
      updates: { name: "Error Handler" }
    }
  ]
});
// IF node branches and error connections automatically updated
\`\`\`

### Name Collision Protection
Attempting to rename a node to an existing name returns a clear error:
\`\`\`
Cannot rename node "Old Name" to "New Name": A node with that name already exists (id: abc123...).
Please choose a different name.
\`\`\`

### Usage Notes
- Simply rename nodes with updateNode - no manual connection operations needed
- Multiple renames in one call work atomically
- Can rename a node and add/remove connections using the new name in the same batch
- Use \`validateOnly: true\` to preview effects before applying

## Removing Properties with null

To remove a property from a node, set its value to \`null\` in the updates object. This is essential when migrating from deprecated properties or cleaning up optional configuration fields.

### Why Use null?
- **Property removal**: Setting a property to \`null\` removes it completely from the node object
- **Validation constraints**: Some properties are mutually exclusive (e.g., \`continueOnFail\` and \`onError\`). Simply setting one without removing the other will fail validation
- **Deprecated property migration**: When n8n deprecates properties, you must remove the old property before the new one will work

### Basic Property Removal
\`\`\`javascript
// Remove error handling configuration
n8n_update_partial_workflow({
  id: "wf_123",
  operations: [{
    type: "updateNode",
    nodeName: "HTTP Request",
    updates: { onError: null }
  }]
});

// Remove disabled flag
n8n_update_partial_workflow({
  id: "wf_456",
  operations: [{
    type: "updateNode",
    nodeId: "node_abc",
    updates: { disabled: null }
  }]
});
\`\`\`

### Nested Property Removal
Use dot notation to remove nested properties:
\`\`\`javascript
// Remove nested parameter
n8n_update_partial_workflow({
  id: "wf_789",
  operations: [{
    type: "updateNode",
    nodeName: "API Request",
    updates: { "parameters.authentication": null }
  }]
});

// Remove entire array property
n8n_update_partial_workflow({
  id: "wf_012",
  operations: [{
    type: "updateNode",
    nodeName: "HTTP Request",
    updates: { "parameters.headers": null }
  }]
});
\`\`\`

### Migrating from Deprecated Properties
Common scenario: replacing \`continueOnFail\` with \`onError\`:
\`\`\`javascript
// WRONG: Setting only the new property leaves the old one
n8n_update_partial_workflow({
  id: "wf_123",
  operations: [{
    type: "updateNode",
    nodeName: "HTTP Request",
    updates: { onError: "continueErrorOutput" }
  }]
});
// Error: continueOnFail and onError are mutually exclusive

// CORRECT: Remove the old property first
n8n_update_partial_workflow({
  id: "wf_123",
  operations: [{
    type: "updateNode",
    nodeName: "HTTP Request",
    updates: {
      continueOnFail: null,
      onError: "continueErrorOutput"
    }
  }]
});
\`\`\`

### Batch Property Removal
Remove multiple properties in one operation:
\`\`\`javascript
n8n_update_partial_workflow({
  id: "wf_345",
  operations: [{
    type: "updateNode",
    nodeName: "Data Processor",
    updates: {
      continueOnFail: null,
      alwaysOutputData: null,
      "parameters.legacy_option": null
    }
  }]
});
\`\`\`

### When to Use null
- Removing deprecated properties during migration
- Cleaning up optional configuration flags
- Resolving mutual exclusivity validation errors
- Removing stale or unnecessary node metadata
- Simplifying node configuration`,
