Registry for managing available skills.

SkillStore provides a centralized place to register and retrieve skills. It can generate a formatted prompt section listing all available skills for inclusion in agent system prompts.

Usage Example

SkillStore store = new SkillStore();
store.register(pdfSkill);
store.register(dataAnalyzerSkill);
// Get a specific skill
Optional skill = store.get("pdf-processor");
// Generate prompt section
String skillsSection = store.generatePromptSection();
// Returns:
// ## Available Skills
// - pdf-processor: Process PDF files...
// - data-analyzer: Analyze data...

Integration with Agents

Agent agent = Agent.builder()
    .name("Assistant")
    .skillStore(store)  // Registers all skills as tools
    .build();
