# Parallel Execution Patterns
### When to Load
- **Trigger**: Multi-agent tasks, concurrent operations, spawning subagents, parallelizing independent work
- **Skip**: Single-step tasks or sequential workflows with no parallelization opportunity
## Core Concept
Parallel execution spawns multiple subagents simultaneously using the Agent tool (named `Task` before Claude Code 2.1.63; `Task` still works as an alias). Subagents run in the background by default, so N tasks run concurrently, dramatically reducing total execution time.
**Critical Rule**: ALL Agent calls MUST be in a SINGLE assistant message for true parallelism. If the calls are in separate messages, they launch one after another.
## Execution Protocol
