Learn to prioritize engineering perception over prompting for better agent performance in AI systems
Action Steps
- Identify the limitations of prompting in AI systems
- Focus on engineering perception to improve agent performance
- Rename and reorganize functions to increase accuracy
- Prioritize visibility and clarity in system design
- Test and refine the system to reduce hallucinations
Who Needs to Know This
Developers and AI engineers can benefit from this approach to improve agent quality and reduce hallucinations
Key Insight
💡 Agent quality depends on what the model can see, not how clever the prompt is

I've watched teams spend weeks rewriting the same system prompt.
Different phrasings. More examples. Clearer instructions. The agent still picks the wrong tool. Still hallucinates. Still feels broken.
Then they rename six functions and accuracy jumps 30%.
This pattern shows up constantly. The model doesn't care how clever your prompt is. It cares about what it can _see_.
