Notes from real work

Make your agent review its own work before you push

Fanning out parallel reviewers catches confident wrong answers. It also produces confident wrong findings.

At the end of a session, before I push, I tell Claude to "fan out." That launches a set of reviewers in parallel instead of one. Different lens each: correctness, blast radius, test coverage. Separat

Writing notes from inside the work
