vsql-extension-builder skillA

vsql-extension-builder is agent-read markdown (skill) from villagesql/villagesql-skills: Build a VillageSQL extension end-to-end using the 7-phase persona-driven workflow: requirements, feasibility, scaffold, implementation, CTO review, UAT, and documentation. Supports C++ (default) and Rust implementations. Discovers the current VEF API from live SDK sources during Phase 1 feasibility and Phase 2 bootstrap — no hardcoded API names. Works from any directory..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add villagesql/villagesql-skills/vsql-extension-builder@git:20260828.e98bfc7
Exact content
mdr add villagesql/villagesql-skills/vsql-extension-builder@sha256:ca5530377b9a49f9

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
