vsql-extension-builder is an agent skill that builds a VillageSQL extension for MySQL end-to-end through a 7-phase persona-driven workflow, according to the item description and the villagesql-skills GitHub README. It is commonly used to port PostgreSQL extensions to MySQL, per the item description. The README states that the skill discovers the current VEF API from live SDK headers rather than relying on hardcoded API names. It is designed to run inside multiple coding agents — Claude Code, Gemini CLI, agy, Codex, Cursor, Amp, Kiro, OpenCode, and OpenClaw — as listed in the README. The README also documents a quick-install script and manual, agent-specific installation steps.

Overview

According to its homepage, VillageSQL describes itself as 'the Innovation Platform for MySQL' and as an open-source, drop-in replacement for MySQL that adds an extension framework for custom data types, functions, and (per the homepage) upcoming custom indexes. The homepage lists shipped extensions including AI, UUID, Network Address, Cryptographic Functions, HTTP, Cube, Boolean, REST, Trigram, and Fuzzy String Match, and states that extensions are installed with a standard SQL INSTALL EXTENSION command. The homepage also lists 'Agent Skills' — including vsql-extension-builder — as a way to build VillageSQL extensions with an AI coding agent.
