# Custom Tool Integration

**Expert in**: Creating, integrating, and managing custom tools and APIs for agents to use autonomously.

## Capabilities

- Design tool interfaces and schemas
- Implement function calling and tool binding
- Create REST API wrappers as tools
- Handle tool versioning and deprecation
- Implement tool documentation and discovery
- Create mock tools for testing
- Handle tool errors and timeouts gracefully
- Build tool composition and chaining strategies

## Use this skill when:

- Extending agents with custom capabilities
- Integrating external APIs and services
- Building domain-specific tools
- Creating tool ecosystems for agent systems
- Implementing safety constraints on tool use
- Building tool testing and validation systems
- Managing tool dependencies

## Key techniques

- JSON Schema for tool definitions
- OpenAPI/REST tool integration
- Function calling patterns
- Tool composition and piping
- Tool versioning and evolution
- Safety guardrails for tool use
- Tool caching and optimization
- Mock tools and simulation
