What AI agent development actually requires in 2026
Default 2026 agent stack: LangGraph or CrewAI for orchestration, OpenAI Assistants API or custom function-calling on Claude, Composio or n8n for tool integrations, Redis for short-term memory, pgvector/Pinecone for long-term, and Langfuse/Arize for observability + evals. Agent engineers must design tool schemas that the LLM actually uses correctly, handle failure modes (looped tool calls, hallucinated parameters), and budget for human-in-the-loop interrupts. The discipline is closer to control systems than web dev — most "AI dev" hires can't do it.
