arch-upkeep

arch-upkeep is a meta architecture skill for keeping existing projects aligned with the canonical starter stacks:

• arch-tsdown-monorepo — pnpm monorepo for TS libs with tsdown per package
• arch-tsdown — single-package TS library with tsdown
• arch-tsdown-cli — CLI apps built on tsdown
• arch-unplugin — libraries built as unplugin (Vite/Rollup/Webpack/ESBuild)
• arch-webext-vue — browser extensions using Vue
• arch-vscode — VS Code extensions

Use this skill when a project already exists and you want to:

• Identify what architecture it currently matches (lib / CLI / monorepo / webext / vscode / unplugin / mixed)
• Plan a migration to one of the canonical arch-* starters
• Incrementally upgrade tooling, scripts, and CI without rewriting app logic

This skill does not re-specify each architecture in detail — it helps you pick which arch-skill to apply and in what order.
