About Prompt Foundry

Extension for Visual Studio Code - Forge complex AI prompts and specs from a library of evolving blocks. Prompt Foundry is a VS Code extension that makes AI more consistent and effective in large codebases. Instead of rewriting context every session, you build a personal library of reusable prompt blocks*, architecture notes, coding standards, behavioural contracts, and snap them together before each task. A bundled MCP server lets the AI write discoveries back into that library, so your prompts improve over time without manual upkeep.
