Ninth discovery: error handling is built into prompts. Anthropic anticipates edge cases and tells Claude how to handle them. If the input data is:
– Incomplete: State what's missing and make reasonable assumptions
– Contradictory: Identify the contradiction and

Anthropic’s Thinking Tags for Complex Reasoning
By
–
Fifth discovery: they use thinking tags for complex reasoning. When the task requires multi-step logic, Anthropic explicitly asks Claude to show its work. Before answering, wrap your reasoning in tags.
Include:
– Assumptions you're making
– Alternative -

Anthropic’s granular role definition technique
By
–
Third technique: role definition goes way deeper than "you are an expert." Anthropic specifies expertise granularly. Weak role definition: You are a software engineer. Anthropic's method: Senior backend engineer with expertise in:
– Distributed systems architecture

Second pattern: they separate thinking from output. Most prompts blend everything together. Anthropic isolates the reasoning process. Standard prompt: Analyze this data and create a report. Anthropic's structure: First, analyze the data following these steps:

Claude’s XML tag obsession revealed
By
–
First discovery: they're obsessed with XML tags. Not markdown. Not JSON formatting. XML. Why? Because Claude was trained to recognize structure through tags, not just content. Look at how Anthropic writes prompts vs how everyone else does it: Everyone else: You are a legal

this is also backed by work in Dipper (prompt ensembles) showing that feeding multiple diverse prompts in parallel improves reasoning and reduces blind spots. and the more you mix prompt styles – contrast, random pivoting, persona shifts – the more the model “sees” new
