automatically activated when Claude detects matching patterns in your request: ``` User: "Set up Kubernetes deployment with Helm chart" → Activates: helm-chart-scaffolding, k8s-manifest-generator User: "Build a RAG system for document Q&A" → Activates: rag-implementation, prompt-engineering-patterns User: "Optimize Python async performance" → Activates: async-python-patterns, python-performance-optimization ``` ### Progressive Disclosure Skills use a three-tier architecture for token efficiency: 1. **Metadata** (Frontmatter): Name and activation criteria (always loaded) 2. **Instructions**: Core guidance and patterns (loaded when activated) 3. **Resources**: Examples and templates (loaded on demand) ### Integration with Agents Skills work alongside agents to provide deep domain expertise: - **Agents**: High-level reasoning and orchestration - **Skills**: Specialized knowledge and implementation patterns Example workflow: ``` backend-architect agent → Plans API architecture ↓ api-design-principles skill → Provides REST/GraphQL best practices ↓ fastapi-templates skill → Supplies production-ready templates ``` ## Specification Compliance All 107 skills follow the [Agent Skills Specification](https://github.com/anthropics/skills/blob/main/agent_skills_spec.md): - ✓ Required `name` field (hyphen-case) - ✓ Required `description` field with "Use when" clause - ✓ Descriptions under 1024 characters - ✓ Complete, non-truncated descriptions - ✓ Proper YAML frontmatter formatting ## Creating New Skills To add a skill to a plugin: 1. Create `plugins/{plugin-name}/skills/{skill-name}/SKILL.md` 2. Add YAML frontmatter: ```yaml --- name: skill-name description: What the skill does. Use when [activation trigger]. --- ``` 3. Write comprehensive skill content using progressive disclosure 4. Add skill path to `marketplace.json`: ```json { "name": "plugin-name", "skills": ["./skills/skill-name"] } ``` ### Skill Structure ``` plugins/{plugin-name}/ └── skills/ └── {skill-name}/ └── SKILL.md # Frontmatter + content ``` ## Benefits - **Token Efficiency**: Load only relevant knowledge when needed - **Specialized Expertise**: Deep domain knowledge without bloat - **Clear Activation**: Explicit triggers prevent unwanted invocation - **Composability**: Mix and match skills across workflows - **Maintainability**: Isolated updates don't affect other skills ## Resources - [Anthropic Skills Repository](https://github.com/anthropics/skills) - [Agent Skills Documentation](https://docs.claude.com/en/docs/claude-code/skills)
