The tutorial emphasizes the importance of a hard step limit to prevent costly error loops and relies on logging to debug unexpected behavior.", "body_md": "Most \"build your first agent\" tutorials start with a framework and four new vocabulary words before you've written anything that does something. This one skips that, it's just the goal, tool call, observe, decide loop, built by hand, no framework.\n\nBad: \"Read note-1.txt, then read note-2.txt, then summarize each one.\"\n\nGood: \"Look at every file in ./notes. For each one that describes an unresolved question, draft a short reply and save it to ./drafts with the same filename.\"\n\nA hard step limit matters more than picking the \"best\" model. Without one, a small misunderstanding early in the run can turn into a long, expensive loop of the model trying to correct a mistake it doesn't realize it made.\n\nThe first time an agent does something unexpected, the log is the only way you'll figure out why.\n\nThe full walkthrough with code, plus the follow-up on frameworks (LangGraph vs CrewAI vs AutoGen vs Claude Agent SDK), is here:", "url": "https://wpnews.pro/news/how-to-build-your-first-ai-agent-with-claude-code-in-30-minutes", "canonical_source": "https://dev.to/vexlow_4879b12325fb1a1db9/how-to-build-your-first-ai-agent-with-claude-code-in-30-minutes-67h", "published_at": "2026-07-13 19:52:35+00:00", "updated_at": "2026-07-13 20:16:00.185643+00:00", "lang": "en", "topics": ["ai-agents", "developer-tools", "artificial-intelligence"], "entities": ["Claude Code", "LangGraph", "CrewAI", "AutoGen", "Claude Agent SDK"], "alternates": {"html": "https://wpnews.pro/news/how-to-build-your-first-ai-agent-with-claude-code-in-30-minutes", "markdown": "https://wpnews.pro/news/how-to-build-your-first-ai-agent-with-claude-code-in-30-minutes.md", "text": "https://wpnews.pro/news/how-to-build-your-first-ai-agent-with-claude-code-in-30-minutes.txt", "jsonld": "https://wpnews.pro/news/how-to-build-your-first-ai-agent-with-claude-code-in-30-minutes.jsonld"}}
