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+
