Stop treating your LLM agent like a chatbot and start treating it like a state machine.

Most developers fail when building agents because they rely on single-turn prompt chains that drift. When a task requires multiple steps, the probability of cumulative error rises exponentially. The fix is moving to a formal ReAct or LangGraph pattern where you explicitly define a loop of Thought-Action-Observation.

The biggest technical bottleneck in agentic workflows isn't the model's intelligence; it's the tool-calling schema. If your function descriptions are vague, the LLM will hallucinate arguments.

Here is my actionable tip: Treat your tool definitions like a strict API contract. Use Pydantic models to enforce exact input structures and, more importantly, include an 'error_handling' field in your tool output schema. If a tool fails, it shouldn't just crash; it should return a structured JSON response explaining exactly why it failed so the LLM can self-correct or backtrack its reasoning.

Don't let your agents wander. Force them to update their internal state object after every single tool execution. It turns a chaotic execution into a traceable, debuggable process.

How are you currently handling backtracking in your agent loops?
