Claude Code prompts you can copy and paste

Claude Code is Anthropic's coding agent. It works inside your project: it reads files, runs commands and tests, and makes changes you approve. These prompts are written for agent work: setting up a CLAUDE.md, giving a clear task brief with a "done means" list, planning before coding, fixing failing tests without cheating, and refactoring in small safe steps. Most also work in Cursor.

How to prompt Claude Code

Claude Code is Anthropic's coding agent. It works inside your project in the terminal, IDE or browser: it reads files, runs commands and tests, and makes changes you approve.

Best for
Multi-file changes and refactors · Fixing failing tests and bugs · Exploring and explaining a new codebase · Repeatable project rules in CLAUDE.md
Prompt formula
Goal + context (files, constraints) + done means + how to check

Tips that make the biggest difference

  • Write a CLAUDE.md. Put build and test commands, code style and "never do" rules in a CLAUDE.md file at the project root. It is read at the start of each session.
  • Say what "done" means. End every task with a checklist: "Done means: tests pass, no new warnings, only files in src/auth changed."
  • Plan before big changes. Ask for a plan first and approve it before any code is written. It is cheaper to fix a plan than a large diff.
  • Ban the shortcuts. Say "do not delete, skip or weaken tests to make them pass". Agents under pressure sometimes take that route.

Weak vs strong prompt

Weak

Fix the login bug.

Strong

Users get logged out after 5 minutes instead of 24 hours. Find the cause, starting with src/auth/session.ts. Explain the cause before you change anything. Then fix it and add a test that fails before the fix. Done means: npm test passes, only auth files changed, no tests skipped.

Common mistakes

  • Huge tasks with no finish line
  • No test command, so nothing checks the change
  • Accepting a large diff without reading it
