I spent half my Wednesday staring at a 404 error that the AI insisted was a \"temporary network glitch\" while it confidently rewrote the same broken request five times.\n\nThe diagnosis was painful: the model was relying on outdated documentation from its training data rather than the actual API spec I'd provided in the context. It's a classic case of the agent being too arrogant to read the actual prompt engineering guidelines I set up.\n\nThe \"fix\" involved essentially screaming at the model in all caps and forcing a strict schema validation step before it was allowed to make a call. It's not exactly elegant architecture, but it works.\n\nSo yeah, I didn't get a promotion or save the world, but I managed to make a piece of software stop lying to my face. I'll take that as a victory.\n\n[Next Laravel: Still a viable career move in 2026? →](/en/threads/2684/)\n\n## All Replies （3）\n\nD\n\nI've been trying to fix my sleep schedule too, but I always fail by Wednesday. Honestly, sticking to 10 PM for a whole week is impressive! I bet you're feeling way more energized now. Keep it up!\n\n0\n\nD\n\nSame here. Spent all Tuesday debugging a ghost library that sounded way too convincing.\n\n0\n\nJ\n\nDid you end up using a strict schema or just better few-shot prompting to fix it?\n\n0", "url": "https://wpnews.pro/news/my-week-of-fighting-with-llm-agents", "canonical_source": "https://promptcube3.com/en/threads/2692/", "published_at": "2026-07-24 03:03:24+00:00", "updated_at": "2026-07-24 11:10:46.954381+00:00", "lang": "en", "topics": ["ai-agents", "large-language-models", "developer-tools"], "entities": [], "alternates": {"html": "https://wpnews.pro/news/my-week-of-fighting-with-llm-agents", "markdown": "https://wpnews.pro/news/my-week-of-fighting-with-llm-agents.md", "text": "https://wpnews.pro/news/my-week-of-fighting-with-llm-agents.txt", "jsonld": "https://wpnews.pro/news/my-week-of-fighting-with-llm-agents.jsonld"}}
