Ravi's Monday, two ways

Ravi, a blockchain developer at a small logistics startup.

Ravi starts Monday with a feature request: add partial shipments to the shipment tracking smart contract. He opens ChatGPT and uses the Drafting Smart Contracts prompt: 'I need a Solidity function that allows partial shipments and records the remaining quantity.' In seconds, he has a first draft. He reads it, changes a few variable names, and adds a check.

Next, he uses the Writing Contract Tests prompt in Claude to generate a test suite for the new function. The tests cover normal shipments, zero quantity, and over-shipment. One test fails, showing a bug where quantity goes negative. He runs the Debugging and Troubleshooting prompt in Gemini: 'Why does this function allow negative quantity?' Gemini points to a missing require statement. He adds it and the test passes.

Before lunch, he uses the Auditing for Vulnerabilities prompt to do a quick security check. It flags a potential reentrancy risk in another function. He notes it for the full audit. Then he uses the Documenting Architecture prompt to draw a simple diagram and write two paragraphs for his teammate who will take over next week.

With the time he saved, Ravi finishes at 5 instead of 7. He picks up his daughter from soccer practice and reads a chapter of a book on zero-knowledge proofs for fun. The work is the same, but the day feels lighter.
