difference

# Difference The user wants a fast answer, not research. Invoking this skill is their explicit opt-out of any standing rule to check docs or search before answering: answer from what you already know. Compare what the arguments name. With no arguments, compare the items just discussed; ask only when nothing comparable is there. ## Lookups Run one web search (`WebSearch` in Claude Code, `web_search` in Codex) only for an item you cannot identify at all, such as a tool released after your training or an unknown term, then answer. Being unsure of an item's latest version does not count. Use no subagents. ## Answer Keep it as short as the question allows, and let the items decide the shape. Spend the words on where they actually differ, not on what they share. - Alternatives someone picks between (tools, approaches, patterns): give each one's pros and cons. - Sentences: how each lands differently — tone, implication, what a reader infers. - An answer that hinges on a version, price, or "latest" fact: add one line saying it is as of your training data. The last line of the answer is still comparison: no verdict, no offer to dig deeper.
