The Big Prompt Library is a collection of prompts, system prompts, and LLM instructions for various large language model providers and solutions.
The repository addresses the need to understand how to write effective prompts and system instructions for LLMs across different platforms. It gathers examples of system prompts, custom instructions, jailbreak prompts, and security-focused instruction protections used with services like ChatGPT, Claude, Microsoft Copilot, Gemini, and others. The collection serves an educational purpose, helping developers and users learn prompt engineering techniques and the mechanics of how different LLM systems interpret and respond to instructions.
Developers should use this repository to study real-world prompt patterns and understand the landscape of LLM instruction design. It suits anyone building custom GPTs, working with multiple LLM providers, or seeking to understand prompt injection risks and defenses. The repository includes articles covering practical topics such as system inventory details of ChatGPT's sandbox environment, Python and Linux packages available in code interpreters, Claude Code's tool invocation patterns, and telemetry behavior in bring-your-own-key setups. These articles provide technical depth beyond simple prompt examples, offering reverse-engineering insights and security analysis of LLM systems.
The project maintains a structured collection organized by topic, with articles documenting technical investigations into LLM behavior and capabilities. The repository includes detailed technical documentation covering sandbox environments, package inventories, and security analysis of LLM systems. Content spans from educational prompt examples to in-depth technical articles analyzing LLM internals and security implications.
