Activation

Skills are automatically activated when Claude detects relevant context in your request. For example:

"Optimize this slow database query" → activates database-optimization
"Review this pull request" → activates code-review
"Set up CI/CD pipeline" → activates ci-cd-pipeline
"Make this site accessible" → activates frontend-accessibility

Customization

Each skill can be customized by editing its SKILL.md file:

• Modify description to change activation triggers
• Update allowed-tools to restrict tool usage
• Add project-specific guidelines in the content
• Create reference.md for additional documentation
• Add examples.md for code examples
