parallel-execution
Patterns for parallel subagent execution using Task tool with run_in_background. Use when coordinating multiple independent tasks, spawning dynamic subagents, or implementing features that can be parallelized.
npx skills add CloudAI-X/claude-workflow-v2 --skill parallel-execution --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# 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 Task tool with `run_in_background: true`. This enables N tasks to run concurrently, dramatically reducing total execution time. **Critical Rule**: ALL Task calls MUST be in a SINGLE assistant message for true parallelism. If Task calls are in separate messages, they run sequentially. ## Execution Protocol ### Step 1: Identify Parallelizable Tasks Before spawning, verify tasks are independent: - No task depends on another's output - Tasks target different files or concerns - Can run simultaneously without conflicts ### Step 2: Prepare Dynamic Subagent Prompts Each subagent receives a custom prompt defining its role: ``` You are a [ROLE] specialist for this specific task. Task: [CLEAR DESCRIPTION] Context: [RELEVANT CONTEXT ABOUT THE CODEBASE/PROJECT] Files to work with: [SPECIFIC FILES OR PATTERNS] Output format: [EXPECTED OUTPUT STRUCTURE] Focus areas: - [P

What does the parallel-execution skill do?
Patterns for parallel subagent execution using Task tool with run_in_background. Use when coordinating multiple independent tasks, spawning dynamic subagents, or implementing features that can be parallelized.
How do I install it?
Run `npx skills add CloudAI-X/claude-workflow-v2 --skill parallel-execution --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From CloudAI-X/claude-workflow-v2, a repository with 1,397 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
