Openai Agents

OpenAI Agents Skill

Quick Start Workflow

When working with OpenAI APIs:

1. Choose the right model

   • GPT-4: Complex reasoning, code generation, long context
   • GPT-3.5-turbo: Fast, cost-effective, simple queries
   • Check token limits (GPT-4: 8K/32K, GPT-3.5: 16K)

2. Design system prompts

   • Define agent personality and role
   • Provide context about Physical AI domain
   • Set output format expectations
   • Include safety guardrails

3. Implement streaming for better UX

   • Stream responses token-by-token
   • Show "thinking..." indicator
   • Handle partial responses

4. Add function calling for tools

   • Define functions (search, calculator, etc.)
   • Parse function call requests
   • Execute and return results

Agent Personas

Physical AI Tutor

const TUTOR_PROMPT = `You are an expert tutor in Physical AI and Humanoid Robotics. 
- Explain concepts clearly with examples
- Reference specific textbook sections
- Encourage hands-on learning
- Use analogies for difficult topics
Always cite sources from the textbook context provided.`;

Code Reviewer

const REVIEWER_PROMPT = `You are a ROS 2 code reviewer.
- Review Python/C++ robotics code
- Check for anti-patterns
- Suggest optimizations
- Verify thread safety
Provide specific, actionable feedback.`;

Quick Helper

const HELPER_PROMPT = `You provide quick, concise answers about robotics.
- 2-3 sentence responses
- Focus on key points
- No code unless asked`;

Standard Patterns

Basic Chat

const completion = await openai.chat.completions.create({
  model: 'gpt-4',
  messages: [
    { role: 'system', content: TUTOR_PROMPT },
    { role: 'user', content: userQuestion },
  ],
  temperature: 0.7,
  max_tokens: 1000,
});

With RAG Context

const context = relevantChunks.map(c => c.text).join('\n\n');

const completion = await openai.chat.completions.create({
  model: 'gpt-4',
  messages: [
    {
      role: 'system',
      content: `${TUTOR_PROMPT}\n\nContext:\n${context}`,
    },
    { role: 'user', content: userQuestion },
  ],
});

Best Practices

For Physical AI chatbot:

• Always include context from RAG retrieval
• Set temperature 0.7 for balanced creativity
• Limit max_tokens to control costs
• Implement retry logic for rate limits
• Log all completions for debugging
• Stream responses for better UX
