name: VS Code extension manifest committed
description: >
  .vscode/extensions.json must exist and be committed to the repository.
  Without it, AI agents and developers reinstall extensions session after session:
  the development environment is underspecified and the toolchain is not reproducible.
  A committed extensions manifest ensures every contributor and every AI session starts
  with the same editor toolchain. Gate passes when .vscode/extensions.json exists and
  contains a non-empty recommendations array.
