What problem does it solve? When multiple unrelated test failures or bugs appear across different files and subsystems, investigating them sequentially wastes time. This Skill provides a structured pattern for delegating each independent problem domain to a focused subagent so investigations run concurrently without shared context or interference. ## Core Features & Use Cases - Independence Assessment: A decision flowchart helps determine whether failures are truly independent and safe to parallelize, or related and better handled by a single agent. - Focused Agent Prompts: A proven prompt structure ensures each subagent gets a specific scope, clear goal, explicit constraints, and a defined output format. - Parallel Dispatch Pattern: Issuing multiple subagent dispatches in one response triggers concurrent execution, while one per response runs sequentially. - Use Case: After a major refactoring leaves 6 failures across 3 test files (abort logic, batch completion, race conditions), dispatch three agents simultaneously, then review summaries, check for conflicts, and run the full suite to integrate. ## Quick Start Ask the assistant to dispatch one parallel subagent per failing test file so each independent failure is investigated and fixed concurrently.
