YouTube Agent Tutorial

Step 1: Add the YouTube Title Generator Agent

1. Click to add a new workflow action
2. Select "Invoke agent"
3. Name the action "YT title gen"
4. Select the YouTube title generator agent
5. Input message is set to system last message by default
6. Save the workflow

Step 2: Add Description Generator and Editor Agents

1. Add second Invoke agent: "youtube description action"
2. Add third Invoke agent: "YouTube title description edit action"
3. Switch to vertical layout for easier viewing

Step 3: Implement Variables for Parallel Input

Ensure both generators receive the initial user input, and the editor receives both outputs.

1. Add a Set Variable action after the start section
2. Create variable "local userinput"
3. Set value to system.last message.text
4. Update both generators to use local userinput as input
5. Capture outputs: YouTube Title output, YouTube Description output

Step 4: Concatenate Output for the Editor

1. Add Set Variable action
2. Create variable "YouTube title description output"
3. Set value to concatenation of Title + Description outputs
4. Update Editor input to use this concatenated variable

Step 5: Adding Human-in-the-Loop (Conditional Approval)

1. Add "Ask a Question" action
2. Display the editor output in the question
3. Ask: "Do you approve? Type YES or describe what changes you want."
4. Save response to "approval input" variable

Step 6: Implement If/Then/Else and Loop

1. Add If/Then/Else block
2. IF condition: user response equals "yes" -> proceed to email
3. ELSE: Set variable combining outputs + user feedback
4. Use Go To action to loop back to title generator
5. Workflow re-runs with new context until approval

Step 7: Email Integration

1. Add Set Variable for "email prompt"
2. Concatenate: recipient address + subject + body (approved content)
3. Add Invoke Agent for email agent
4. Use email prompt variable as input
