Claude Prompt Library — Community Prompts That Work

Most people write Claude prompts from scratch every time. They get an answer, tweak it slightly, try again. It works, but it is slow and it throws away every lesson learned the last time. This library exists to fix that. Every prompt here was written by someone who ran into a real problem, figured out what wording actually produced a great result, and chose to share it so the next person does not have to start from zero.

The library is powered by GitHub Discussions, which means the community votes on what works and buries what does not. The prompts you see at the top of the list are there because real users upvoted them. When you find a prompt that works well for you, upvote it too — that is what keeps the best material surfaced for everyone who comes after you.

How the Prompt Library Works

Every prompt in this library lives as a GitHub Discussion in the Ideas category of the HowToClaudeAtoZ repository. Anyone with a GitHub account can contribute a prompt or upvote an existing one.

Submitting a prompt. Click the Share a Prompt button below. This opens a new GitHub Discussion. Give your prompt a clear title, paste the full prompt text in the body, and add a short note explaining what task it solves and any tips for using it well. Context matters — the best contributions include an example output so readers know what to expect.

Voting. Open any prompt from the list below and click the upvote arrow at the top of the discussion. The number next to the arrow is the total upvote count. Prompts are sorted by upvotes so the most useful float to the top automatically. You can also add a comment to a discussion to share variations, edge cases, or improvements you have discovered.

Discovery. This page is rebuilt on every site deploy and fetches the current top-voted prompts live from GitHub. That means what you see here is always the most recent community consensus on what works. If you contributed a prompt last week and it gathered upvotes, it will appear here on the next build.

The system is deliberately simple. No accounts to create beyond a GitHub login. No complex rating system. Just a clean upvote mechanism that reflects real utility rather than algorithmic noise.

What Makes a Great Claude Prompt

The prompts that consistently earn the most upvotes in this library share a few qualities. Understanding them helps you write prompts that work first time and are worth sharing.

Role and context first. Claude responds better when it knows who it is writing for and why. Starting with "You are an expert copywriter working for a SaaS startup" gives Claude a frame that shapes every word of the response. Compare that to "write me some copy" — the output quality difference is immediate and obvious.

Explicit output format. Telling Claude exactly what format you want — a numbered list, a table, a single paragraph, a JSON object — eliminates the back-and-forth of asking it to restructure the answer. The best prompts in this library specify format in the first few lines.

Constraints that focus the output. Word limits, tone requirements, audience level, and things to avoid are all constraints that narrow the solution space and produce sharper results. "Write a 150-word product description for a first-time buyer who has never heard of this category" gives Claude far more to work with than "write a product description."

An example or a template. If you know what the output should look like, include an example. Claude is excellent at following patterns when shown one. Many of the top prompts here include a fill-in-the-blanks template that lets anyone adapt the prompt to their specific situation without needing to understand the underlying mechanics.

Share Your Workflow

Individual prompts are powerful, but multi-step workflows are where Claude compounds. If you have figured out a sequence — perhaps a research prompt that feeds into a drafting prompt that feeds into an editing prompt — the Share Your Workflow category is the right place to document it.

Share a workflow at the Share Your Workflow GitHub Discussions category. The best submissions explain the full sequence, what Claude is doing at each stage, and what the final output looks like. Screenshot comparisons between a single-prompt approach and a multi-step workflow are especially effective at showing the quality difference.

Workflows that have been shared by the community are listed on the prompt-library page alongside individual prompts, sorted by the same upvote mechanism. If you want to see your workflow featured here, write it up clearly and let the community vote it to the top.

Why Contribute?

The HowToClaudeAtoZ library grows in usefulness proportionally to the number of people contributing to it. A library with ten prompts is a curiosity. A library with a thousand well-voted prompts is a reference tool that saves hours every week.

For contributors, sharing a prompt gets your work in front of a relevant audience — people who are actively looking for better ways to use Claude. If your prompt is genuinely useful, it will be upvoted, linked to, and referenced in related guides on this site. Several guides on HowToClaudeAtoZ already link to community discussions as primary examples.

For the community, every prompt shared is one fewer wheel reinvented. Claude is flexible enough that the difference between a mediocre prompt and an excellent one is often a single sentence. The library captures those sentences so they are not lost.

For beginners, the library is a learning resource. Reading well-crafted prompts is one of the fastest ways to develop an intuition for how Claude interprets instructions. Every upvoted prompt is an implicit lesson in what Claude responds well to.
