Claude prompts
Claude responds measurably better to explicit structure — XML-style tags, imperative instructions, stated output formats. These prompts are written for that, not generic copy pasted from a ChatGPT list.
Every prompt lists the exact tool and version it was tested against.
Set up a Claude Project so you stop re-explaining context every chatA structured project-knowledge document plus custom-instructions block for Claude Projects, so every new chat inside the project inherits your context automatically instead of you re-pasting it.Claude (Projects)Claude Enterprise2026-07-29Build a working interactive tool in a Claude Artifact in one promptA single prompt that produces a self-contained, live-rendered interactive tool (a calculator, converter, or small utility) as a Claude Artifact, with inputs, live outputs, and no external dependencies.Claude (Artifacts)Claude.ai2026-08-02Get a real synthesis out of a document too long to read yourselfA long-document synthesis prompt built for pasting an entire large document into Claude's long context window, forcing section-by-section grounding instead of a shallow top-level summary.Claude (Sonnet 4.6, 200K+ context)Claude (Opus 4.6, 1M context)2026-07-24Use explicit XML tags to stop Claude from mixing up your inputsA multi-part task template using explicit XML-style tags to separate instructions, context, and reference material, exploiting Claude's documented strength at parsing tagged structure over freeform prose.Claude (Sonnet 4.6)Claude (Opus 4.6)2026-07-18Turn up reasoning effort for a genuinely hard analytical problemA prompt that explicitly invokes high reasoning effort for a multi-step analytical task, structuring the problem so Claude's extended thinking is spent verifying its own steps rather than restating the question.Claude (Opus 4.6, extended thinking)Claude (Sonnet 4.6, extended thinking)2026-08-01Get Claude to write in your actual voice, not generic AI voiceA style-matching prompt that feeds Claude several of your own writing samples and asks it to extract and name the concrete patterns before writing anything new, instead of vaguely imitating a vibe.Claude (Sonnet 4.6)Claude (Opus 4.6)2026-07-11Compare several long documents against each other, not just summarize each oneA structured comparison prompt for feeding Claude several documents at once (proposals, contracts, resumes) and forcing a criteria-by-criteria comparison table instead of separate summaries you have to compare yourself.Claude (Sonnet 4.6, long context)Claude (Opus 4.6)2026-07-30Turn a recurring small decision into a reusable Artifact widgetA compact prompt for building a small, single-purpose interactive Artifact — a checklist, scorer, or picker — for a decision you make repeatedly, so you get a reusable tool instead of a one-off chat answer.Claude (Artifacts)Claude.ai2026-07-14Synthesize research findings with citations you can actually verifyA research-synthesis prompt that requires every claim to be tied to a specific numbered source you supply, and forces an explicit list of claims Claude could not support, instead of a fluent but uncheckable summary.Claude (Sonnet 4.6)Claude (Opus 4.6)2026-07-21Make Claude critique and revise its own draft before you see itA two-pass prompt that forces Claude to generate a first draft, critique it against a named rubric as if reviewing someone else's work, and then produce a revised version, so you see the improved output instead of doing the editing yourself.Claude (Sonnet 4.6)Claude (Opus 4.6)2026-07-09Get a spreadsheet analyzed with formulas explained, not just numbersA spreadsheet-analysis prompt for Claude for Excel / Sheets that asks for findings, the exact formulas behind them, and flagged data-quality problems, so you get an auditable analysis instead of a black-box number.Claude for ExcelClaude for Sheets2026-07-27Force a brainstorm to produce real options, not ten flavors of one ideaA brainstorming prompt that imposes hard structural constraints — a fixed count, mandatory diversity across a named axis, and a stated tradeoff per idea — so Claude produces genuinely distinct options instead of minor variations on its first idea.Claude (Sonnet 4.6)Claude (Opus 4.6)2026-07-16
