Agent Skills

Agent Skills are modular packages that extend Claude's capabilities with specialized domain knowledge, following Anthropic's Agent Skills Specification. This plugin ecosystem includes 129 specialized skills across 27 plugins, enabling progressive disclosure and efficient token usage.

Overview

Skills provide Claude with deep expertise in specific domains without loading everything into context upfront. Each skill includes:

• YAML Frontmatter: Name and activation criteria
• Progressive Disclosure: Metadata → Instructions → Resources
• Activation Triggers: Clear "Use when" clauses for automatic invocation

How Skills Work

Activation

Skills are 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:

• ✓ 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:
   yamlCopy

   ---
   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:
   jsonCopy

   {
     "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
