Use when an app uses @pierre/diffs to render or edit code files, diffs, patches, merge conflicts, or CodeView review surfaces, including React, vanilla JavaScript, SSR, workers, annotations, selection, and custom Shiki languages or themes.
Use when an app needs a Pierre light or dark theme from @pierre/theme for Shiki, VS Code, Cursor, or Zed, including soft, vibrant, protanopia, deuteranopia, and tritanopia variants.

Use when an app uses @pierre/trees to render or control a file tree, including React, vanilla JavaScript, SSR, web components, selection, search, rename, drag and drop, icons, git status, and themes.
Use when running repo scripts, adding or changing dependencies, editing package.json files, installing packages, publishing packages, or deciding when pnpm package operations versus Bun runtime commands should be invoked.
Use when adding or changing packages/apps, TypeScript configs, workspace dependencies, package references, exports, or monorepo project-reference relationships.
Use when working with the repo's moonx root:wt worktree helper, Pierre-managed worktrees, dev-server port offsets, stale server cleanup, Playwright fixtures, or Chrome debug instances. Do not use this as a substitute for host-provided workspace isolation.
Use when adding or running tests, checking snapshots, choosing between Bun tests and Playwright, running lint/format/typecheck, or deciding the verification scope for a change.
