System Prompt Templates for AI Coding Agents
TL;DR
A shared system prompt template designed to guide AI-powered coding agents toward more reliable, structured, and effective code generation behavior. It is a prompt engineering artifact rather than a software library or framework. System prompts for coding agents help standardize and improve the behavior of LLM-based coding assistants (e.g., ChatGPT, Claude, Copilot Chat) by setting explicit rules, constraints, and personas — reducing hallucinations, improving code quality, and enforcing best practices without fine-tuning.

Open the Gist URL and copy the system prompt text. Paste it into the 'system prompt' or 'custom instructions' field of your preferred AI coding tool (e.g., ChatGPT, Claude Projects, Cursor, or Continue.dev). Adjust any placeholders or persona-specific sections to match your stack or team conventions. Test it against your typical coding tasks and iterate on the instructions as needed.
