arch-vscode is a VSCode extension starter (based on antfu/starter-vscode) that uses reactive-vscode for reactive APIs and composables, tsdown for a single CJS bundle, and vscode-ext-gen for type-safe contributes metadata. It provides a minimal, opinionated setup: defineExtension entry, defineConfig/defineLogger, Extension Host debugging, and vsce/vsxpub for packaging and publishing.

The skill is based on starter-vscode (arch-vscode source), generated at 2026-01-30.

Recommended practices:

Keep contributes and generated meta in sync via pnpm update (or Run on Save)
Use reactive-vscode composables for state and disposables; use CJS build with external vscode
Prefer onCommand activation when possible
