Today's Prompt Engineering: Fastest-Growing Projects — June 23, 2026
Today's the Prompt Engineering space, we see a diverse array of projects gaining traction across various domains such as marketing copy generation, AI-driven video ad creation, and even enhancing developer productivity through better prompt management. Among these, TexasBedouin's vibe-check stands out with its user-friendly approach to guiding product managers from initial idea to polished execution.
TexasBedouin/vibe-check takes a beginner from a vague concept to a concrete plan, offering guidance on GitHub basics, clean-code practices, and iterative development. Its growth score of 24.14 and over 400 stars indicate its popularity among developers looking for straightforward tools to kickstart their projects.
MADEVAL/MindFluence leverages cognitive biases to enhance marketing copy across various mediums such as ads and landing pages. With a growth score of 23.20, it is quickly becoming a go-to solution for marketers seeking data-driven approaches to improve conversion rates.
liyue-aigc's female-portrait-director offers modular skills for directing detailed AI-generated female portraits. This repository has gained significant attention with over 690 stars, reflecting its utility in generating high-quality portrait prompts without the need for extensive technical knowledge.
Apeironics/prompt-refine-skill introduces an agent skill that silently refines prompts for ongoing model tasks, aiming to improve overall performance and efficiency. With a steady stream of commits (85 in 30 days) and a growth score of 17.44, it demonstrates active development and growing relevance in the prompt optimization space.
jaredrhod's ai-memory-vault provides a system for giving AI persistent memory through markdown files within an Obsidian vault. Its unique approach to integrating AI with existing note-taking systems has garnered interest, as evidenced by its growth score of 14.30 and 26 stars.
LichAmnesia/awesome-ad-video-prompts curates high-quality prompts specifically for AI-driven video ads across multiple platforms like Seedance 2.0 and Veo 3. With 149 stars and a growth score of 13.00, it stands out as a valuable resource for creators looking to enhance their video ad campaigns.
harnessworks/harness-starter-kit offers a prompt-first approach to making repositories safer for AI coding agents by providing essential templates and configurations. Its active development (100 commits in the last month) and growth score of 12.57 highlight its potential impact on improving collaboration between human developers and AI tools.
OttoRenner's Gentle-Coding project explores how different prompt engineering techniques can affect LLM performance, offering insights into more empathetic ("Gentle Parenting") approaches to mitigate issues like cognitive freezing. With a growth score of 11.24 and 103 stars, it is attracting researchers interested in the psychological aspects of AI interactions.
moely-ai's claude-fable-5-prompt repository compiles advanced system prompts for developers and researchers working with Claude Fable 5. Despite its lower growth score (7.69) and fewer commits, it has attracted a niche audience looking to push the boundaries of prompt engineering in specific AI environments.
OnlyTerp/prompt-cache-skills provides drop-in fixes for LLM agent harnesses aimed at improving prompt caching efficiency. With 104 stars and a growth score of 5.98, this project is gaining traction among developers seeking performance optimizations within their existing AI workflows.
These projects collectively showcase the evolving landscape of Prompt Engineering, where tools are increasingly tailored to specific needs across various industries and technical domains.
