What problem does it solve? Investigating multiple unrelated failures sequentially wastes time when each problem domain is independent. This Skill coordinates parallel background subagents so each failure gets investigated and fixed concurrently without shared context or interference. ## Core Features & Use Cases - Independent Domain Identification: Groups failures by subsystem to determine which can be worked on in parallel versus sequentially. - Focused Agent Prompts: Provides a structure for self-contained agent prompts with specific scope, constraints, and expected output. - Parallel Dispatch Pattern: Issues multiple invoke_subagent calls in a single response so agents run concurrently rather than sequentially. - Use Case: After a major refactoring leaves 6 test failures across 3 files (abort logic, batch completion, race conditions), dispatch one agent per test file, then review summaries, check for conflicts, and run the full suite to integrate the fixes. ## Quick Start Ask the agent to dispatch one parallel subagent per failing test file, each with a focused prompt describing the failures, constraints, and expected summary output.
