What is prompt engineering in Transformer LLMs?

It's crafting input token sequences to make the model behave as desired—handwritten, generated, doesn't matter. Everything else reduces to this.

Are AI agents just overhyped prompt engineering?

Yep, per this thesis: agents chain prompts, but no new compute magic. They're useful wrappers, not paradigm shifts.

Does this mean I should ditch workflows and tools?

Nah—use 'em for dev velocity. But know they're prompt plumbing. Focus on token efficiency.

Code snippet reducing AI agent workflow to a complex prompt sequence

⚡ Key Takeaways

All AI mechanisms like agents and workflows reduce to prompt engineering in Transformers—no exceptions. 𝕏
Tools and MCPs are just prompt-declared illusions; quality comes from schema prompts, not execution. 𝕏
Abstractions add dev value but don't change the model's token-only worldview—optimize inputs ruthlessly. 𝕏
