When you've got multiple independent failures across different test files or subsystems, this cuts debugging time by running separate agents in parallel instead of investigating sequentially. Each agent gets a focused scope like "fix the 3 failures in agent-tool-abort.test.ts" with all necessary context but no shared state. Works well for scenarios like timing issues in one file, API bugs in another, and race conditions in a third. The key is ensuring the problems are actually independent, otherwise agents waste time duplicating work or missing connections between failures.
