parallel-batch-executor
について
このスキルは、xargsとジョブ制御を使用してbashで並列タスク実行を可能にし、大幅なパフォーマンス向上を実現します。複数のファイルやリポジトリなど、独立した項目に対するバッチ操作、特にI/Oバウンドなタスクに最適です。順序が重要でなく、依存関係や共有リソース要件のないタスクに開発者が使用すべきであり、依存関係や共有リソースを必要とするタスクには使用を避けるべきです。

Parallel Batch Executor
When to Use This Skill
✅ Use when:
- Processing multiple independent files or items
- Running the same operation across multiple repositories
- Batch operations that don't depend on each other
- Need significant performance improvements
- Operations are I/O bound rather than CPU bound
❌ Avoid when:
- Tasks have dependencies on each other
- Order of execution matters
- Shared resources require synchronization
- Single task that can't be parallelized

## Performance Tuning
### Optimal Parallelism
```bash
# CPU-bound tasks: match CPU cores
PARALLEL=$(nproc)
# I/O-bound tasks: 2-4x CPU cores
PARALLEL=$(($(nproc) * 2))
# Network-bound tasks: higher parallelism
PARALLEL=20
# Memory-constrained: limit based on available RAM
AVAILABLE_MB=$(free -m | awk '/^Mem:/{print $7}')
TASK_MB=100 # Estimate per task
PARALLEL=$((AVAILABLE_MB / TASK_MB))
Throttling
# Add delay between task starts
printf '%s\n' "${items[@]}" | xargs -I {} -P "$PARALLEL" bash -c "
sleep 0.1 # 100ms delay
process_item \"{}\"
"

swarm-advanced
その他This skill provides advanced swarm orchestration patterns for complex distributed workflows like research, development, and testing. It enables developers to coordinate multiple specialized agents using both MCP tools and CLI commands for parallel execution. Use it when you need to manage sophisticated multi-agent systems with mesh topologies and coordinated task distribution.
when-optimizing-prompts-use-prompt-architect
その他Prompt Architect is a framework for developers to systematically analyze, refine, and optimize prompts using evidence-based techniques. It helps improve AI response quality and consistency by identifying anti-patterns and validating changes through A/B testing. Use it when you need to refactor an underperforming prompt or design a new, effective one from scratch.
deepspeed
デザインThis skill provides expert guidance for distributed training using Microsoft's DeepSpeed library. It helps developers implement optimization techniques like ZeRO stages, pipeline parallelism, and mixed-precision training. Use this skill when working with DeepSpeed features, debugging code, or learning best practices for large-scale model training.
performance-analysis
その他This skill provides comprehensive performance analysis and bottleneck detection for Claude Flow swarms, helping developers identify optimization opportunities. It offers real-time monitoring, profiling of swarm operations, and generates detailed reports with actionable recommendations. Use this skill when you need to diagnose performance issues and improve the efficiency of your Claude Code applications.
