# LangChain ReAct Agent Skill

## Capabilities

- Implement ReAct (Reasoning + Acting) agent patterns using LangChain

- Configure tool binding and function calling for agents

- Design thought-action-observation loops

- Integrate with various LLM providers (OpenAI, Anthropic, etc.)

- Handle agent memory and state persistence

- Implement error handling and retry logic for agent actions

## Target Processes

- react-agent-implementation

- function-calling-agent

## Implementation Details

### Core Components

1. **Agent Executor Setup**: Configure LangChain AgentExecutor with appropriate settings

2. **Tool Integration**: Bind tools with proper schemas and descriptions

3. **Prompt Engineering**: Design system prompts for ReAct reasoning patterns

4. **Output Parsing**: Parse agent outputs and handle structured responses

### Configuration Options

- LLM model selection and parameters

- Tool definitions and schemas

- Memory type (buffer, summary, vector)

- Max iterations and timeout settings

- Verbose/debug mode configuration

### Dependencies

- langchain

- langchain-openai / langchain-anthropic

- Python 3.9+
