Collection of LLM system prompts, agentic personas, cognitive frameworks & prompt engineering experiments

Agentic prompts are the most important code you're not engineering. PromptKit fixes that — composable, version-controlled prompt components (personas, protocols, formats, templates) that snap together into reliable, repeatable prompts for bug investigation, design docs, code review, security audits, and more. Works with any LLM.

The Elizabethan Lover is a full-stack Generative AI application that simulates a "Snapchat" experience with historical figures. Unlike generic chatbots, this project enforces rigid historical personas (Shakespeare, Romeo, Juliet) using System Prompt Engineering and Google's Gemini 2.5 Flash architecture.

An open-source web app that enhances and refines AI prompts using advanced prompt engineering techniques like Chain of Thought, Few-Shot Learning, Persona Injection, and more. Supports multiple LLM providers and domains with a modern, intuitive UI built with React, TypeScript, and Tailwind CSS.

A curated collection of prompts, modes, and configurations to enhance AI coding assistants. Provides ready-to-use templates for prompt engineering, custom agent personas, and AI-driven development workflows. Optimized for Roo Code but adaptable for many platforms.

PersonaGPT is a Python-based, LLM & Langchain-powered multi-role chatbot built using GPT models and FastAPI, featuring role-based prompt engineering and buffered conversational memory to deliver context-aware, domain-specific interactions, professional personas such as Doctor, Lawyer, and Teacher.

Developing small prototypes and proof-of-concept AI architectures leveraging advanced prompt engineering, multi-step reasoning (CoT), and persona-based agent simulations

This AI chatbot is the persona of Hitesh Choudhary (Youtuber) made using OpenAI. Its completely based on prompt engineering, the way it answers is because of prompt.py file. You can change the persona by changing personality and behaviour instructions in that file.

Prompt engineering techniques that work in practice. Co-Dialectic: your AI coaches your prompts, you coach its answers. Paste one file into any AI. Five systems activate automatically — personas, prompt coaching, context management, auto-learning, teaching. Free and open-source.

Immersive AI personality platform powered by dynamic system prompt engineering and deployed on Vercel.AI personality platform built with Next.js and Groq, featuring dynamic persona injection.

This project demonstrates activation-level persona steering on a small open-source LLM using TinyLlama/TinyLlama-1.1B-Chat-v1.0. Instead of only using prompt engineering, it learns a “persona vector” directly in hidden state space and injects it during generation.

In this lab, I learned how to use prompt engineering patterns to control and improve AI responses. I practiced persona prompting, cognitive verifier, question refinement, providing information to generate questions, and root prompts. These techniques help guide AI to give clearer, more accurate, and structured outputs.

This project aims to explore the extent to which persona-driven prompt engineering can influence AI-generated argumentation. Using Microsoft’s Phi-2 model, a 2.7 billion parameter LLM noted for its strong reasoning abilities (Microsoft Research, 2023), the study applies the Big Five personality framework to guide the AI’s responses.
