This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.

Parallel execution rules — when and how to use parallel agents and tool calls. Use PROACTIVELY when facing 2+ independent tasks. Prevents sequential anti-patterns.

Beginner

Key capabilities

  • Fetch multiple URLs simultaneously
  • Read multiple independent files
  • Run independent verification checks
  • Review multiple files in parallel
  • Research unrelated sub-topics concurrently
  • Determine if sequential execution would waste time

How it works

The skill provides rules for when and how to use parallel agents and tool calls. It mandates parallelization for independent tasks like fetching multiple URLs or reading multiple files, and includes a self-check before execution.

Inputs & outputs

You give it
Two or more independent tasks
You get back
Parallel execution of tasks

When to use parallel

  • Parallelizing file reads
  • Running independent research tasks
  • Fetching multiple resources

About this skill

Parallel Execution Skill

Source: AI Toolbox .agent/rules/parallel-execution.md

Mandatory Parallelization

  • Fetching 2+ URLs simultaneously
  • Reading 3+ independent files
  • Running independent verification checks
  • Reviewing multiple files
  • Researching unrelated sub-topics

Self-Check Before Execution

  1. Do they depend on each other's output? → If NO: PARALLELIZE
  2. Would sequential execution waste time? → If YES: PARALLELIZE
  3. Are there 2+ independent sub-tasks? → If YES: PARALLELIZE

Agent Types

  • Explore — Fast file/keyword search, URL fetching
  • general-purpose — Complex research, multi-step analysis

Full Rules

Read at: .agent/rules/parallel-execution.md

When not to use it

  • When tasks depend on each other's output
  • When there are fewer than two independent tasks

Limitations

  • Parallelization is not applicable if tasks depend on each other's output
  • Parallelization is for 2+ independent tasks
  • The skill prevents sequential anti-patterns

How it compares

This skill proactively identifies opportunities for parallel execution based on task independence, preventing sequential bottlenecks common in manual or generic workflows.
