Tips for great skills
The agent is already smart
Only include knowledge it doesn't have — specific workflows, schemas, tool integrations, domain expertise.
Context window is a public good
Keep SKILL.md under 500 lines. Split large content into reference files that the agent loads on demand.
Match freedom to fragility
Text instructions for flexible tasks, executable scripts for brittle ones where consistency is critical.
Description is the trigger
The description field is what the agent sees first. Be clear about what the skill does and when to use it.
