Criteria for Skill vs Agent

TIP

Decision flow for choosing between Skills and Agents.

Decision Flow

Comparison Table

Perspective	Skill	Agent
Context	Shared with main	Independent (separate context window)
Impact on Main	Consumes context	Returns only result summary
Execution Speed	Fast (load only)	Slightly slower (new process)
Use Cases	Procedures, templates, references	Reviews, analysis, independent tasks
Programming Analogy	import / require	Separate process / Worker Thread

When to Use Skills

• Component generation procedures
• Coding standards reference
• Template file application
• Short-duration standard tasks

When to Use Agents

• Code review: Run in independent context to avoid Sycophancy
• Large-scale analysis: Does not burden main context
• Specialist domain tasks: Address Knowledge Boundary
• Quality verification: Cross-model QA with different models

Combination Patterns

User: "Create a new Feature Module"
  ├─ Skill: component-generator (generate by referencing procedures)
  │
  └─ Agent: code-reviewer (review generated result in independent context)
