14 Free Claude Prompts for Developers — RohanKit Prompt Library

A well-written prompt is the difference between a generic Claude response and one that actually solves your problem. Writing good prompts takes practice — but you shouldn't have to start from scratch for every common developer task.

RohanKit has 14 ready-to-use Claude prompts for developers. Copy, paste, and get immediately useful output — no prompt engineering required.

The 14 Claude Prompts Available

Rubber Duck Debugging Partner

Talk through a bug out loud with Claude as your rubber duck. Claude asks clarifying questions, reflects your logic back, and helps you spot the flaw — without just giving you the answer. Often the act of explaining it is what breaks the deadlock.

Senior Code Reviewer

Paste your code and get a review from the perspective of a senior engineer — not just syntax checks, but architecture concerns, edge cases, performance issues, and maintainability feedback.

Conventional Commit Message Generator

Paste your git diff, get a properly formatted conventional commit message. Consistent commit history with zero effort.

PR Description Writer

Paste your diff or list of changes — get a clear, professional pull request description with summary, motivation, and testing notes. Useful for both solo developers and teams.

API Documentation Generator

Paste your route handler or controller code — get clean, complete API documentation with endpoint description, request schema, response schema, and examples.

Rubber Duck Architecture Review

Describe your planned architecture or system design — Claude asks probing questions that surface assumptions, edge cases, and potential problems before you build.

Test Case Generator

Paste a function or component — get a comprehensive list of test cases covering happy path, edge cases, error conditions, and boundary values.

Error Message Explainer

Paste any error message or stack trace — get a plain-English explanation of what went wrong, why it happened, and the most likely fix.

README Generator

Describe your project — get a professional README with overview, installation, usage, API reference, and contributing guide.

Performance Audit Prompt

Paste your code — get a performance analysis identifying bottlenecks, unnecessary re-renders, inefficient queries, and specific optimisation suggestions.

Security Review Prompt

Paste your code — get a security-focused review checking for common vulnerabilities, input validation gaps, authentication issues, and data exposure risks.

Refactoring Guide

Paste messy or legacy code — get a step-by-step refactoring plan that improves structure without changing behaviour.

Sprint Retrospective Facilitator

Describe your sprint — Claude runs a structured retrospective covering what went well, what didn't, and actionable improvements for the next sprint.

Claude.ai vs Claude Code — Which to Use

Claude.ai — use for prompts that involve explanation, planning, documentation, or review. The browser interface is better for longer conversations and back-and-forth discussion.

Claude Code — use for prompts that directly relate to code in your project. Claude Code has access to your files and can make changes directly. Better for refactoring, test generation, and commit messages.

RohanKit organises all 42 items by platform — each prompt, skill, and config is tagged for Claude.ai browser, Claude Code terminal, or Claude Code VS Code so you always know where to use it.
