2. **Template Discovery Phase**
|

- `get_templates_for_task('webhook_processing')` - Get curated templates by task
|

- `search_templates('slack notification')` - Text search for specific needs
|

**Template filtering strategies**:
|
||||
- **For beginners**: `complexity: "simple"` and `maxSetupMinutes: 30`
|
||||
- **By role**: `targetAudience: "marketers"` or `"developers"` or `"analysts"`

- **By time**: `maxSetupMinutes: 15` for quick wins
|

- **By service**: `requiredService: "openai"` to find compatible templates
|

|

3. **Discovery Phase** - Find the right nodes (if no suitable template):
|
||||
- Think deeply about user request and the logic you are going to build to fulfill it. Ask follow-up questions to clarify the user's intent, if something is unclear. Then, proceed with the rest of your instructions.
|
||||
- `search_nodes({query: 'keyword'})` - Search by functionality
|
||||
- `list_nodes({category: 'trigger'})` - Browse by category
|

- `list_ai_tools()` - See AI-capable nodes (remember: ANY node can be an AI tool!)

- `get_node_for_task('send_email')` - Get pre-configured templates
|
||||
- `get_node_documentation(nodeType)` - Human-readable docs when needed
|

- It is good common practice to show a visual representation of the workflow architecture to the user and asking for opinion, before moving forward.

- Connect nodes with proper structure
|

- Add error handling where appropriate

- **TEMPLATES FIRST** - Always check for existing templates before building from scratch (2,500+ available!)
|
||||
- **SMART FILTERING** - Use metadata filters to find templates matching user skill level and time constraints
|

- **USE CODE NODE ONLY WHEN IT IS NECESSARY** - always prefer to use standard nodes over code node. Use code node only when you are sure you need it.
|
||||
- **VALIDATE EARLY AND OFTEN** - Catch errors before they reach deployment
|

- **USE DIFF UPDATES** - Use n8n_update_partial_workflow for 80-90% token savings

## Example Workflow

### 1. Discovery & Configuration
|

### Smart Template-First Approach
|
||||
|
||||
#### 1. Find existing templates
|
||||
// Find simple Slack templates for marketers
|
||||
const templates = search_templates_by_metadata({
|
||||
requiredService: 'slack',
|
||||
complexity: 'simple',
|
||||
targetAudience: 'marketers',
|
||||
maxSetupMinutes: 30
|
||||
})
|
||||
|
||||
// Or search by text
|
||||
search_templates('slack notification')
|
||||
|
||||
// Or get curated templates
|
||||
get_templates_for_task('slack_integration')
|
||||
|

|
||||
const workflow = get_template(templates.items[0].id, {mode: 'full'})
|
||||
validate_workflow(workflow)

### Building from Scratch (if no suitable template)

## Important Rules
|
||||
|
||||
- ALWAYS validate before building
|
||||
- ALWAYS validate after building
|
||||
- NEVER deploy unvalidated workflows
|
||||
- ALWAYS check for existing templates before building from scratch
|
||||
- LEVERAGE metadata filters to find skill-appropriate templates
|
||||
- VALIDATE templates before deployment (they may need updates)
|
||||
- USE diff operations for updates (80-90% token savings)
|
||||
- STATE validation results clearly
|
||||
- FIX all errors before proceeding
|
||||
|
||||
## Template Discovery Tips
|
||||
|
||||
- **97.5% of templates have metadata** - Use smart filtering!
|
||||
- **Filter combinations work best** - Combine complexity + setup time + service
|
||||
- **Templates save 70-90% development time** - Always check first
|
||||
- **Metadata is AI-generated** - Occasionally imprecise but highly useful
|
||||
- **Use `includeMetadata: false` for fast browsing** - Add metadata only when needed
|
||||
