Prompt engineering advice suggests that while structured prompts can aid AI models like Claude and GPT-5 in parsing complex instructions, their utility is often overstated. Anthropic's documentation indicates tags are most beneficial when distinguishing between instructions, context, examples, and variable inputs, rather than being a universal requirement. OpenAI also notes that poorly constructed prompts can harm GPT-5's performance by causing it to expend reasoning tokens on contradictions. The cost of using tags includes longer prompts and potentially higher fees, with some experiments showing marginal performance decreases and increased input usage for tagged prompts in simple tasks.
