Agentic Software Engineering — AI × software engineering, made practical.
A whiteboard test — and a real production refund bug — for telling an actual agent apart from a chatbot wearing a trenchcoat.
Running three parallel agents on the same ticket and trusting the 2-of-3 majority almost cost us a customer relationship — because agreement between correlated agents isn't confirmation, it's the same blind spot showing up twice.
A production incident traced back to a junior's agent-authored PR revealed that clean, fast diffs can ship with zero understanding underneath them — and most teams haven't redesigned onboarding to account for it.
Giving every engineer a coding agent seat multiplied throughput but not judgment capacity, and the fix was a review contract, not more seats.
A hiring-loop story about why the scarce skill in the agent era is distrust of confident-looking code, not the ability to write it.
Agent-assisted engineers aren't losing their coding skills, they're quietly losing the ability to defend architectural decisions — and the fix is a trackable ratio of decisions made versus decisions merely inferred.
A real Tuesday — including an eleven-minute incident where an agent executed a flawed plan perfectly across 600 tenants — shows the senior engineer's job shifting from writing code to designing the harness that decides whether an agent's conclusions are safe to act on.
A billing bug that sailed through human review shows where the real skill shift is happening: writing specs precise enough that a literal-minded agent can't misread them, and deciding on purpose which parts of the system still need a human holding the whole picture.
