Stopped by the @noderails booth at @ETHGlobal! 🚀
Really impressive to see crypto payments getting simpler with gasless checkout, stablecoin settlements and chargeback support.
Loved exploring @wallcardapp too!

Prompt engineering asks: "how do I phrase this?"
Context engineering asks: "what does the model even need to see?"
One's about wording. The other's about the entire information environment: system prompt, retrieved docs, tool outputs, conversation history.
Bad: "Schedule an appointment for this patient."
Good: same prompt + clinic policies + doctor availability + patient prefs + live scheduling API output.Same model. Wildly different answer quality. That's context engineering.
If you want the full breakdown (prompt vs context engineering, context rot, the 4 pillars, live example): youtu.be/Qx0fCqpkBus?si=CSX5…
Counterintuitive finding: bigger context windows ≠ better performance.Dump in 4,000 pages of irrelevant Slack messages and the model struggles just like you would. Researchers call this "context rot."More isn't the goal. Relevant is.
