When to Add a Specialist

Beyond planner/builder/reviewer/deployer, you can add specialists for recurring high-skill tasks: a security auditor, a docs writer, a perf profiler, a migration writer. The rule of thumb: add a specialist when the same task fails the generalist roster three times in a row.

Premature specialists explode complexity. Too few specialists leave gaps. The right sequence is: ship with the four core roles → notice repeated failures → add the one specialist that addresses the repeated failure → measure → repeat.
