The Agent that doesn't need a rewrite
The agent that survives its first year in production is usually a thin layer over the system you already have. Your ten-year-old codebase is not the obstacle. It is the asset.
Evals Are the Tests You Should Have Written First
Renaming tests to evals did not create a new discipline. It created permission to skip an old one - the obligation to define what correct means before shipping.
Why Agents Get Canceled

AI in Long-Lived Systems
Every AI integration is a bet that you can monitor something you do not fully control.
When Code Is No Longer Scarce
As code generation gets cheaper, the real bottleneck shifts from production to coordination, comprehension, and judgment.
