Two variants are shared: a general 'ask clarifying questions before answering' and a more targeted version capping questions at three for coding tasks. The upfront time cost is small compared to the effort saved debugging code built on wrong assumptions. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What prompt line can I add to Claude Code to stop it from making assumptions about my requirements? Appending the line 'Ask clarifying questions before answering' to a Claude Code prompt causes it to pause and ask about missing details instead of silently defaulting to its most likely assumption. For coding-heavy tasks, a more specific version works better: 'Before writing code, ask me up to three clarifying questions if anything about the requirements, file locations, or existing conventions is ambiguous.' _daily.dev surfaces practical prompting tricks like this for developers refining their Claude Code workflow._ ## Similar posts on daily.dev - [I added one line to my Claude prompts, and the improvement was immediate](https://daily.dev/posts/i-added-one-line-to-my-claude-prompts-and-the-improvement-was-immediate-p0xv0aits) · XDA Developers · 0 upvotes · 0 comments - [How to Efficiently Prompt Claude Code](https://daily.dev/posts/how-to-efficiently-prompt-claude-code-m0bc2szoo) · Towards Data Science · 1 upvotes · 0 comments --- Tags: [#llm](https://daily.dev/tags/llm), [#ai-coding](https://daily.dev/tags/ai-coding), [#claude-code](https://daily.dev/tags/claude-code), [#prompt-engineering](https://daily.dev/tags/prompt-engineering) [View this post on daily.dev](https://daily.dev/posts/i-added-one-line-to-my-claude-code-prompts-and-the-difference-was-night-and-day-rveqxr0nq) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"I added one line to my Claude Code prompts, and the difference was night and day","url":"https://daily.dev/posts/i-added-one-line-to-my-claude-code-prompts-and-the-difference-was-night-and-day-rveqxr0nq","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/i-added-one-line-to-my-claude-code-prompts-and-the-difference-was-night-and-day-rveqxr0nq"},"datePublished":"2026-07-30T19:31:57.833Z","dateModified":"2026-09-14T06:16:25.735Z","description":"Adding a single line to Claude Code prompts — asking the model to pose clarifying questions before writing code — dramatically reduces unwanted assumptions and...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b109c42ed7724d1444c26d8418d75892?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b109c42ed7724d1444c26d8418d75892?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"XDA Developers","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"XDA Developers","logo":"https://media.daily.dev/image/upload/s--kCg6yyAP--/f_auto,q_auto/v1774964407/logos/xda-developers?_a=BAMAMiWQ0","url":"https://daily.dev/sources/xda-developers"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/i-added-one-line-to-my-claude-code-prompts-and-the-difference-was-night-and-day-rveqxr0nq","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":1},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"llm,ai-coding,claude-code,prompt-engineering","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"XDA Developers","item":"https://daily.dev/sources/xda-developers"},{"@type":"ListItem","position":3,"name":"I added one line to my Claude Code prompts, and the difference was night and day"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/i-added-one-line-to-my-claude-code-prompts-and-the-difference-was-night-and-day-rveqxr0nq#faq","mainEntity":[{"@type":"Question","name":"What prompt line can I add to Claude Code to stop it from making assumptions about my requirements?","acceptedAnswer":{"@type":"Answer","text":"Appending the line 'Ask clarifying questions before answering' to a Claude Code prompt causes it to pause and ask about missing details instead of silently defaulting to its most likely assumption.
