Claude prompt templates

Each template turns one everyday task into a structured prompt. Pick the one that matches what you need, fill in a few fields, and copy the result.

Code

Code review prompt

Ask Claude to review a diff for supported issues, ordered by severity, with a location, impact and suggested fix for each finding.

You'll need: Diff or code change

Turn an error message and the code around it into a ranked list of likely causes, a check for each, and a fix you can try.

You'll need: Error message or stack trace, What you expected to happen
Write unit tests

Get unit tests for a function or module in your framework, covering normal cases, edge cases and errors, with each test explained.

You'll need: Code to cover, Test framework

Edit a draft for clarity

Make a draft clearer for a named reader while keeping your meaning and voice, with a short list of what changed and why.

You'll need: Your draft, Who will read it
Reply to an email

Draft a reply that addresses each question in an email, aims at your goal in the tone you choose, and flags what you still need to decide.

You'll need: The email you are replying to, What you want the reply to achieve
Summarize a document

Turn a long document into a faithful summary: main point first, key points by importance, then decisions and open questions.

You'll need: Document

Analyze customer feedback

Group raw customer comments into themes, priorities or feature requests, with counts and quotes that show where each finding comes from.

Extract data to JSON

Pull specific fields out of messy text into JSON that matches your field list, with clear rules for missing or ambiguous values.

You'll need: Source text, Fields to extract

Critique an argument

Test an argument before you rely on it: its main claim, hidden assumptions, weak links and the strongest objection, with fixes.

You'll need: The argument
Explain a concept

Get a concept explained at your level, in the format that helps you most, with a quick self-check and the common misconceptions.

You'll need: Concept
Turn meeting notes into action items

Turn rough meeting notes into a clear list of action items with owners and due dates, plus decisions made and questions left open.

You'll need: Meeting notes

Start from the task, not the wording. If you need a shorter version of something long, use a summary template; if you need fields pulled into a fixed format, use the extraction template.
Each card lists the fields you must fill in. Optional fields make the prompt more specific, but every template produces a usable prompt with only the required ones.
Templates that take long source material put it first inside a named tag, followed by the instructions; the concept template starts with your topic and level instead. Every template page explains why it is built that way.
