55 Production-Ready Claude Prompts for Engineers

I've been using Claude in production for 6+ months. Figured I'd share the 55 prompts that save me the most time.

What You'll Get

• Code Review & Architecture (15 prompts)

  • Prompt: "Review this PR for security issues, edge cases, and performance"
  • Works great for async code review with teams
  • Catches things humans miss in the first pass

• Security & Compliance (10 prompts)

  • Prompt: "Threat model this system from the perspective of an attacker"
  • Saved us from missing OWASP Top 10 issues
  • Compliance framework mapping

• Testing & DevOps (10 prompts)

  • Prompt: "Generate integration tests for this API endpoint"
  • CI/CD automation
  • Chaos engineering scenario planning

• AI & Agentic Loops (5 prompts)

  • Prompt: "Design a multi-agent system where Agent A reviews Agent B's work"
  • Useful for more complex workflows
  • Tool binding and function definitions

• Data & Analytics (5 prompts)

  • Prompt: "Optimize this SQL query for performance on a 100M row table"
  • Financial metrics and reporting
  • Dashboards and KPI definitions

• Other (10 more prompts)

  • Everything else I use regularly
  • Custom domain-specific prompts

Why Compile These?

• Most engineers rediscover the same 50 prompts independently
• Time-to-value is huge — 1 good prompt = 2-4 hours saved
• Licensing is cheap ($49) vs. the value per hour
• These are tested in production, not theoretical

How to Use

1. Download the prompt library
2. Copy a prompt into Claude API / claude.ai / Claude Code
3. Paste your code/context
4. Iterate

No setup. No training. Just prompt engineering.
