Test Parallel Task Tool in SDK

Test whether the Task tool (subagent spawner) is available and works for parallel execution.

Instructions

1. Try to spawn TWO Task subagents in parallel using the Task tool:

   • Task A: Use Explore agent to count files in .claude/skills/
   • Task B: Use Explore agent to count files in scripts/

2. Write results to earnings-analysis/test-outputs/parallel-test-$ARGUMENTS.txt:

CALLER: $ARGUMENTS
TIMESTAMP: {current time}
TASK_TOOL_AVAILABLE: YES or NO
PARALLEL_EXECUTION: SUCCESS or FAILED
TASK_A_RESULT: {result or error}
TASK_B_RESULT: {result or error}
ERROR_IF_ANY: {exact error message if Task tool failed}

IMPORTANT: Actually TRY to use the Task tool. Don't just check if it exists - call it.
