Example: ${t.open}I need to break this problem into parts: first calculate X, then Y${t.close}`:""}

${i?`When you decide to use a tool, wrap your reasoning in ${i.open} and ${i.close} tags.
Example: ${i.open}I'll search for information about climate change${i.close}`:""}

${a?`After getting information, wrap your observations in ${a.open} and ${a.close} tags.
Example: ${a.open}The search revealed that global temperatures have risen by 1.1\xB0C${a.close}`:""}

${p?`When you have a final answer, wrap it in ${p.open} and ${p.close} tags.
Example: ${p.open}Based on my analysis, the answer is 42${p.close}`:""}

Use ONLY these markers for structuring your responses.
