Today's Prompt Engineering: Fastest-Growing Projects — April 21, 2026
Today's Prompt Engineering, we saw a surge of interest in repositories focused on Claude Code and its applications. The growth scores indicate that developers are actively seeking resources to improve their prompt engineering skills, particularly for AI coding agents like Claude. As a result, repositories offering high-quality prompt templates, courses, and research-backed toolkits have gained significant traction.
repowise-dev/claude-code-prompts (Growth Score: 51.70, Stars: 949) stands out as the fastest-growing repository in this category, with its independently authored prompt templates for AI coding agents gaining widespread attention. The repository's high growth score can be attributed to its comprehensive coverage of system prompts, tool prompts, and agent delegation, making it an invaluable resource for developers.
ShipWithAI/claude-code-mastery (Growth Score: 13.81, Stars: 72) offers a free Claude Code course with 16 phases and 55 modules, making it an attractive option for those looking to improve their skills in prompt engineering. The high number of commits over the past 30 days suggests that the community is actively engaged with the repository.
ZeroLu/awesome-happy-horse (Growth Score: 8.25, Stars: 60) provides a community-curated hub for Happy Horse model resources, including prompts and sample outputs. Its moderate growth score indicates a steady interest in this repository as developers seek to explore text-to-video and image-to-video examples.
TaewoooPark/NODEPROMPT (Growth Score: 5.66, Stars: 31) introduces spatial prompt engineering through interactive 3D concept graphs, showcasing the innovative approaches being explored in this field. The repository's growth score suggests a growing interest in novel methods for prompt engineering.
Josh-blythe/bordair-multimodal (Growth Score: 4.50, Stars: 33) offers an open-source test suite for cross-modal and multimodal prompt injection attacks, backed by research from OWASP LLM Top 10 and other reputable sources. Its moderate growth score indicates a niche but dedicated interest in this area of security-focused prompt engineering.
ZeroLu/awesome-gpt-image (Growth Score: 4.32, Stars: 31) collects the best GPT Image 2 prompts and examples from top creators on X. The repository's steady growth score reflects its usefulness as a resource for developers working with image-based prompts.
Leonxlnx/agentic-ai-prompt-research (Growth Score: 3.70, Stars: 2,326) focuses on research into agentic AI coding assistants and reconstructed prompt patterns, attracting a large following due to its comprehensive approach. Although its growth score is relatively low compared to other repositories, its high star count indicates its importance in the community.
OuterSpacee/claude-emotion-prompting (Growth Score: 2.33, Stars: 60) provides research-backed prompting toolkit for Claude, leveraging Anthropic's emotion vectors paper from 2026. The repository's low growth score suggests that it may be a niche interest, but its moderate star count indicates some traction.
JonusNattapong/ClaudeCode-Learning (Growth Score: 1.52, Stars: 28) offers ClaudeCode learning resources for prompt engineering, although the lack of detailed description makes it difficult to determine its specific value proposition. Its low growth score and relatively few stars suggest that this repository may not be as widely recognized or utilized as others in this category.
