What problem does it solve? When multiple unrelated failures appear at once (different test files, different subsystems, different bugs), investigating them sequentially wastes time. This Skill coordinates parallel subagents, each with an isolated context and a narrow scope, so independent problems are investigated and fixed concurrently. ## Core Features & Use Cases - Independent Domain Identification: Group failures by root cause area to decide whether parallel dispatch is appropriate or whether failures are related and need sequential investigation. - Focused Agent Prompts: Construct self-contained agent tasks with clear scope, constraints, and expected output so agents stay on target without inheriting your conversation history. - Review and Integration Workflow: After agents return, verify fixes do not conflict, run the full test suite, and integrate all changes. - Use Case: After a major refactor, three test files fail for different reasons (timing issues, batch completion bugs, race conditions). Dispatch one agent per test file, let all three work concurrently, then merge their independent fixes. ## Quick Start Ask the assistant to dispatch one parallel subagent per failing test file, each with a focused prompt describing the failures, constraints, and the summary it should return.
