Prerequisites

• Tools:
  • OpenAI GPT-4 API or ChatGPT (v4) account
  • Python 3.9+ (for API scripting)
  • Optional: openai Python package (v1.2.0+)
  • Optional: Postman or similar API testing tool
• Knowledge:
  • Basic Python scripting
  • Familiarity with REST APIs
  • Understanding of your organization’s creative approval criteria
• Accounts/Access:
  • OpenAI API key or ChatGPT Plus subscription
  • Sample creative assets (e.g., ad copy, images, or design files)

Step 1: Define Creative Approval Criteria

1. List Your Approval Requirements
   • Gather your creative guidelines—brand voice, legal disclaimers, tone, formatting, etc.
   • Document what counts as “approved” versus “needs revision.”
2. Example Criteria Table

   | Criterion          | Description                                 | Example                                  |
   |--------------------|---------------------------------------------|------------------------------------------|
   | Brand Voice        | Friendly, expert, concise                   | "Welcome to our new feature!"            |
   | Legal Compliance   | Must include legal disclaimer if needed      | "Terms and conditions apply."            |
   | Formatting         | Adheres to 120-character limit               | "Try our new app—free for 30 days!"      |
   | Tone               | No negative or fear-based messaging         | Avoid: "Don’t miss out or you’ll regret!"|
         

3. Tip: Invite stakeholders (legal, brand, creative) to review and approve this criteria list.

Step 2: Create and Test Baseline Prompts

1. Draft a Simple Approval Prompt
   • Start with a direct, clear instruction.
   Review the following ad copy for brand voice, legal compliance, and formatting. Respond with “Approved” or “Needs revision” and specify any required changes.
2. Test the Prompt in ChatGPT or via API
   • Paste your prompt and a sample creative asset into ChatGPT, or use the API:

   $ python
   >>> import openai
   >>> openai.api_key = "sk-..."
   >>> response = openai.ChatCompletion.create(
   ...   model="gpt-4",
   ...   messages=[
   ...     {"role": "system", "content": "You are a creative approval assistant."},
   ...     {"role": "user", "content": "Review the following ad copy for brand voice, legal compliance, and formatting. Respond with 'Approved' or 'Needs revision' and specify any required changes.\n\nAd copy: Try our new app—free for 30 days!"}
   ...   ]
   ... )
   >>> print(response['choices'][0]['message']['content'])
         

   Screenshot description:

3. Iterate
   • Test with varied assets (good/bad examples) and adjust the prompt for clarity.

Step 3: Build Structured, Multi-Part Prompts

1. Add Explicit Criteria and Output Format
   • Use bullet points or numbered lists for clarity.
   Review the following creative asset based on these criteria: 1. Brand voice (friendly, expert, concise) 2. Legal compliance (include required disclaimers) 3. Formatting (max 120 characters) 4. Tone (no negative messaging) Respond in this format: Approval: [Approved/Needs revision] Feedback: [Specific issues or required changes]
2. Test for Consistency
   • Run multiple samples and check that the output always matches your format.

   $ python
   >>> # Repeat the API call with the improved prompt and several ad copy examples.
         

   Screenshot description:

3. Template Example

   
   PROMPT_TEMPLATE = """
   You are a creative approval assistant.
   Review the following creative asset based on these criteria:
   1. Brand voice (friendly, expert, concise)
   2. Legal compliance (include required disclaimers)
   3. Formatting (max 120 characters)
   4. Tone (no negative messaging)
   
   Respond in this format:
   Approval: [Approved/Needs revision]
   Feedback: [Specific issues or required changes]
   
   Creative asset:
   {asset}
   """
   
         

Step 4: Automate Prompting with Python

1. Install OpenAI Python SDK

   $ pip install openai
         

2. Write a Script to Batch-Approve Creative Assets

   
   import openai
   
   openai.api_key = "sk-..."  # Replace with your API key
   
   PROMPT_TEMPLATE = """
   You are a creative approval assistant.
   Review the following creative asset based on these criteria:
   1. Brand voice (friendly, expert, concise)
   2. Legal compliance (include required disclaimers)
   3. Formatting (max 120 characters)
   4. Tone (no negative messaging)
   
   Respond in this format:
   Approval: [Approved/Needs revision]
   Feedback: [Specific issues or required changes]
   
   Creative asset:
   {asset}
   """
   
   assets = [
       "Try our new app—free for 30 days!",
       "Don't miss out or you'll regret it. Sign up now!",
       "Welcome to the future of productivity. Terms and conditions apply."
   ]
   
   for asset in assets:
       prompt = PROMPT_TEMPLATE.format(asset=asset)
       response = openai.ChatCompletion.create(
           model="gpt-4",
           messages=[
               {"role": "system", "content": "You are a creative approval assistant."},
               {"role": "user", "content": prompt}
           ]
       )
       print(f"Asset: {asset}")
       print(response['choices'][0]['message']['content'])
       print("---")

Step 5: Refine with Advanced Prompt Engineering Techniques

1. Use Few-Shot Examples for Greater Accuracy
   • Show the AI what “good” and “bad” approvals look like.

   
   PROMPT_TEMPLATE = """
   You are a creative approval assistant.
   
   Examples:
   Creative asset: Try our new app—free for 30 days!
   Approval: Approved
   Feedback: None
   
   Creative asset: Don't miss out or you'll regret it. Sign up now!
   Approval: Needs revision
   Feedback: Tone is negative; rephrase to avoid fear-based messaging.
   
   Now, review the following creative asset:
   {asset}
   Approval:
   Feedback:
   """
   
         

2. Chain of Thought Prompting
   • Ask the AI to explain its reasoning step-by-step before giving a verdict.

   
   Review the following creative asset. For each criterion, explain your reasoning, then provide an overall approval decision and feedback.

   • Use APIs or workflow automation tools (Zapier, Make, n8n) to trigger AI reviews when new assets are uploaded.

2. Log and Store Results
   • Save AI approval results and feedback to your project management system or creative asset database.

   
   import csv
   
   with open("approval_log.csv", "w", newline="") as csvfile:
       writer = csv.writer(csvfile)
       writer.writerow(["Asset", "Approval", "Feedback"])
       for asset in assets:
           # ... (run approval as above)
           writer.writerow([asset, approval, feedback])
