55 Production-Ready Claude Prompts for Engineers

#ai #claude #programming #productivity

I've been using Claude in production for a while, and I kept noticing the same thing: I was re-deriving the same prompts across every project. Code review, SQL optimization, IAM policies, refactoring, the same patterns, over and over.

So I organized the 55 I actually reach for. Here's what's in them, plus 7 you can grab free.

7 free prompts (no signup)

Before the pitch, here are 7 of them, free, on GitHub:

They cover SQL optimization, async refactoring, API validation, React, Python ETL, IAM policies, and microservice design. Copy, paste your context into the brackets, iterate.

What the full set covers

Code review & architecture (15): e.g. "Review this PR for security issues, edge cases, and performance." Great for async review; catches things a first human pass misses.
Security & compliance (10): e.g. "Threat-model this system from an attacker's perspective." Maps to the OWASP Top 10.
Testing & DevOps (10): integration test generation, CI/CD, failure-scenario planning.
AI & agentic loops (5): multi-agent designs, tool binding, function definitions.
Data & analytics (5): e.g. "Optimize this SQL query for a 100M-row table."
Other specialized (10): the rest I use regularly.

Why package them?

Most engineers rediscover the same ~50 prompts independently.
One good prompt saves 2 to 4 hours. The time-to-value is lopsided.
These are tested in production, not theoretical.

Each prompt in the full set includes the full text, a real example input, a production-ready example output, and notes on adapting it to your project, so you see how it behaves before you run it.
