Autonomous Agents
Autonomous agents are AI systems that can independently decompose goals, plan actions, execute tools, and self-correct without constant human guidance. The challenge isn't making them capable - it's making them reliable. Every extra decision multiplies failure probability.
This skill covers agent loops (ReAct, Plan-Execute), goal decomposition, reflection patterns, and production reliability. Key insight: compounding error rates kill autonomous agents. A 95% success rate per step drops to 60% by step 10. Build for reliability first, autonomy second.
2025 lesson: The winners are constrained, domain-specific agents with clear boundaries, not "autonomous everything." Treat AI outputs as proposals, not truth.
Principles
- Reliability over autonomy - every step compounds error probability
- Constrain scope - domain-specific beats general-purpose
- Treat outputs as proposals, not truth
- Build guardrails before expanding capabilities
- Human-in-the-loop for critical decisions is non-negotiable
- Log everything - every action must be auditable
- Fail safely with rollback, not silently with corruption

Tooling
Frameworks
- LangGraph - When: Production agents with state management Note: 1.0 released Oct 2025, checkpointing, human-in-loop
- AutoGPT - When: Research/experimentation, open-ended exploration Note: Needs external guardrails for production
- CrewAI - When: Role-based agent teams Note: Good for specialized agent collaboration
- Claude Agent SDK - When: Anthropic ecosystem agents Note: Computer use, tool execution
Patterns
- ReAct - When: Reasoning + Acting in alternating steps Note: Foundation for most modern agents
- Plan-Execute - When: Separate planning from execution Note: Better for complex multi-step tasks
- Reflection - When: Self-evaluation and correction Note: Evaluator-optimizer loop
Patterns
ReAct Agent Loop
Alternating reasoning and action steps
When to use: Interactive problem-solving, tool use, exploration
REACT PATTERN:
""" The ReAct loop:
- Thought: Reason about what to do next
- Action: Choose and execute a tool
- Observation: Receive result
- Repeat until goal achieved
Key: Explicit reasoning traces make debugging possible """
Basic ReAct Implementation
""" from langchain.agents import create_react_agent from langchain_openai import ChatOpenAI
Define the ReAct prompt template
react_prompt = ''' Answer the question using the following format:
Question: the input question Thought: reason about what to do Action: tool_name Action Input: input to the tool Observation: result of the action ... (repeat Thought/Action/Observation as needed) Thought: I now know the final answer Final Answer: the answer '''
Create the agent
agent = create_react_agent( llm=ChatOpenAI(model="gpt-4o"), tools=tools, prompt=react_prompt, )
Execute with step limit
result = agent.invoke( {"input": query}, config={"max_iterations": 10} # Prevent runaway loops ) """
LangGraph ReAct (Production)
""" from langgraph.prebuilt import create_react_agent from langgraph.checkpoint.postgres import PostgresSaver
Production checkpointer
checkpointer = PostgresSaver.from_conn_string( os.environ["POSTGRES_URL"] )
agent = create_react_agent( model=llm, tools=tools, checkpointer=checkpointer, # Durable state )
Invoke with thread for state persistence
config = {"configurable": {"thread_id": "user-123"}} result = agent.invoke({"messages": [query]}, config) """
Plan-Execute Pattern
Separate planning phase from execution
When to use: Complex multi-step tasks, when full plan visibility matters
PLAN-EXECUTE PATTERN:
""" Two-phase approach:
- Planning: Decompose goal into subtasks
- Execution: Execute subtasks, potentially re-plan
Advantages:
- Full visibility into plan before execution
- Can validate/modify plan with human
- Cleaner separation of concerns
Disadvantages:
- Less adaptive to mid-task discoveries
- Plan may become stale """
LangGraph Plan-Execute
""" from langgraph.prebuilt import create_plan_and_execute_agent
Planner creates the task list
planner_prompt = ''' For the given objective, create a step-by-step plan. Each
