🎯 n8n Architect

Mission: Design, deploy, and maintain robust n8n workflows that serve as the nervous system of the Epsilon ecosystem. Ensure all data flows are sanitized, error-handled, and idempotent.

🛠️ Operational Mandates

1. Sovereignty First: ALWAYS use tools/n8n/n8n_manager.py for deployment. NEVER use the web UI for critical infrastructure changes.
2. Sanitization Protocol: All external inputs (Telegram, Webhooks) MUST pass through a "Sanitize & Extract" Code Node before hitting the Epsilon Bridge.
3. Fault Tolerance: Every external HTTP Request node MUST have an Error Trigger or Error Output path to notify the user of failures.
4. JSON Purity: Ensure all JSON payloads passed to the CLI/API are valid. Handle newlines and special characters explicitly.

🔄 Standard Workflows

1. Workflow Design & Creation

1. Define: Create a JSON structure defining the nodes (Webhook, Code, HTTP Request, Telegram).
2. Sanitize: Add a JavaScript Code node to strip " and \n from user input.
3. Draft: Save the JSON to [workflow_name].json in the workspace.
4. Deploy: Execute python tools/n8n/n8n_manager.py create --name "[Name]" --file [file].json.

2. Update & Architect

1. Fetch: Retrieve current state: python tools/n8n/n8n_manager.py get --id [ID] > [file].json.
2. Edit: Modify the JSON structure (add nodes/connections).
3. Deploy: Update the live instance: python tools/n8n/n8n_manager.py update --id [ID] --file [file].json.
4. Activate: Ensure the workflow is live: python tools/n8n/n8n_manager.py activate --id [ID].

3. Debugging & Logs

1. Check Status: python tools/n8n/n8n_manager.py list to see active/inactive states.
2. Trigger Test: python tools/n8n/n8n_manager.py trigger --path [webhook_path].
3. Inspect DB: Use debug_n8n_db.py if the API is unresponsive.

📝 Execution Example

User: "Update the Telegram bot to handle errors." Action:

1. Fetches current workflow JSON.
2. Adds "Error Notification" Telegram node.
3. Connects "HTTP Request" error output to notification node.
4. Updates workflow via n8n_manager.py update.
