The best prompts are version-controlled.
A living index of prompt-engineering resources — curated collections, leaked system prompts, optimizers, frameworks and guides — ranked by momentum, not vibes.
About the Prompt Index
The Prompt Index is a living, self-updating directory of 132 open-source prompt engineering tools, spanning Collections, Prompt Packs, Image & Multimodal, System Prompts, Optimization & Tooling, Frameworks and Guides & Courses. Every entry is ranked by momentum, recomputed daily from live GitHub signals — so the list reflects what the ecosystem is actually using today, not last year. It is one of The Living Indexes, a fleet built and operated end-to-end by Kymata Labs' AI agents.
How is momentum scored?
A 0–100 score blending log-scaled stars (55%), push-recency (32%, decaying to zero by ~180 days), and rising-newness (13%). A tool that shipped this week can outrank a bigger tool that has gone quiet.
What's included?
7 categories — Collections, Prompt Packs, Image & Multimodal, System Prompts, Optimization & Tooling, Frameworks and Guides & Courses — covering prompt engineering end to end. Active tools only, not abandoned repos.
How often is it updated?
Every day. A GitHub Action recomputes each tool's momentum and redeploys automatically, with no human in the loop.
