Why This Exists

Most prompt engineering guides teach you what to write. This skill teaches you how to architect prompts — the patterns behind production agentic systems that handle millions of requests.

We analyzed Claude Code's leaked system prompts and the Awesome Prompt Engineering research catalog into one actionable skill. The result goes beyond prompt content:

• Architecture — How Claude Code assembles 15+ modular sections into a single system prompt with static/dynamic caching boundaries
• Behavioral control — How one rule ("be concise") gets enforced from 4 different angles across the prompt
• Agent design — How 5 specialized agent types each get tailored prompts and tool subsets
• Security — How defense-in-depth layers protect against prompt injection in tool results
• Optimization — How A/B testing, automated prompt engineering, and compression work in production

This isn't another "add 'Let's think step by step'" guide. It's the engineering discipline behind prompts that actually ship.
