Writing Effective Descriptions

The description field is crucial - it tells Claude when to invoke the skill.

Good description patterns:

description: This skill should be used when the user asks to "specific phrase", "another phrase", mentions "keyword", or discusses topic-area.

Include:

• Specific trigger phrases users might say
• Keywords that indicate relevance
• Topic areas the skill covers

Skill Content Guidelines

1. Clear purpose: State what the skill helps with
2. When to use: Define activation conditions
3. Structured guidance: Organize information logically
4. Actionable instructions: Provide concrete steps
5. Examples: Include practical examples when helpful

Best Practices

• Keep skills focused on a single domain
• Write descriptions that clearly indicate when to activate
• Include reference materials in subdirectories for complex skills
• Test that the skill activates for expected queries
• Avoid overlap with other skills' trigger conditions
