# My Week of Fighting with LLM Agents > Source: > Published: 2026-07-24 03:03:24+00:00 # My Week of Fighting with LLM Agents My biggest "win" this week was finally stopping my LLM agent from hallucinating a nonexistent API endpoint for three hours straight. 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. The diagnosis was painful: the model was relying on outdated documentation from its training data rather than the actual API spec I'd provided in the context.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. The "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. So 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.

Honestly, sticking to 10 PM for a whole week is impressive! I bet you're feeling way more energized now. Keep it up! 0 D Same here. Spent all Tuesday debugging a ghost library that sounded way too convincing. 0 J Did you end up using a strict schema or just better few-shot prompting to fix it? 0
