## Tier A 🟢 — Canonical (learn it properly)

### Anthropic — Prompt Engineering Interactive Tutorial
Hands-on, exercise-driven course straight from Anthropic. The right place to *learn*, not
just copy.
- **source:** https://github.com/anthropics/prompt-eng-interactive-tutorial
- **reputation:** Official Anthropic · **36,109★** · pushed 2026-03-01
- **last_validated:** 2026-06-02
- **assumes:** Claude API key for the exercises
- **adapt:** none — it's a course; internalize, don't fork.

## Tier B 🔵 — Community-proven reference

### System Prompts of AI Tools
Reverse-engineered system prompts from real shipping agents (Cursor, v0, Devin, etc.).
The single best "how do the pros actually prompt" reference. Read critically — these are
*captured*, not endorsed, and change often.
- **source:** https://github.com/x1xhlol/system-prompts-and-models-of-ai-tools
- **reputation:** **138,685★** · pushed 2026-05-23 (high stars + actively updated)
- **last_validated:** 2026-06-02
- **assumes:** nothing
- **adapt:** study patterns; don't copy a whole prompt wholesale.

### awesome-chatgpt-prompts
Huge community prompt collection. Useful for breadth, but quality is uneven and it's
ChatGPT-flavored — patterns transfer, exact wording often doesn't.
- **source:** https://github.com/f/awesome-chatgpt-prompts
- **reputation:** **163,172★** · pushed 2026-06-02 (very high stars + actively maintained → B-grade reputation; kept in C only because content quality is uneven and ChatGPT-specific)
- **last_validated:** 2026-06-02
- **assumes:** nothing
- **adapt:** harvest a starting prompt, then rewrite for Claude + your task.

### Anthropic Courses
Broader official curriculum (API fundamentals, prompt eval, tool use).
- **source:** https://github.com/anthropics/courses
- **reputation:** Official Anthropic · **21,678★** · pushed 2025-11-13
- **last_validated:** 2026-06-02 (HTML 200)
- **assumes:** Claude API key
- **adapt:** none.

> ⚠️ `anthropics/courses` last pushed **2025-11-13** — >6mo at next review. Per
> `_meta/SCHEMA.md`, treat as **C until reproven** if you read this after ~2026-05.
> The official-source authorship keeps it useful, but check it isn't version-stale.
