-# Monorepo (pnpm)
-
-- Work primarily in:  
-  • src/  
-  • webview-ui/package  
-  • packages/types (shared DTOs)
-- Other workspaces (modify only if instructed):  
-  • evals/  
-  • packages/_/  
-  • apps/_/  
-  • [others]
-- To install deps:  
-  → run `pnpm add <package>` in `<cwd>workspace/directory</cwd>` (updates `<workspace>/package.json`)
-- ⚠️ DO NOT run pnpm in root (root only holds CLI dev-tools in devDependencies, e.g. prettier)
-
-# Turborepo
-
-- ❌ Don’t modify `turbo` config without instruction
-- ✅ You may propose config changes when:
-    1. Adding a shared, cacheable npm task
-    2. Declaring an internal-package dependency that affects the extension build
-
-# Running tests
-
-- Always execute commands using `<cwd>workspace/directory</cwd>` when running any test command
-- To fix failures:
-    1. Target one failing test:  
-       → `npx vitest relative/path/__tests__/name.spec.ts -t "substring"`
-    2. Verify all tests in that module pass:  
-       → `npx vitest relative/path/__tests__/name.spec.ts`
-- File conventions:  
-  • `.spec.ts` → vitest  
-  • `.test.ts` → jest (deprecated)
-- If a test in `.test.ts` fails:  
-  → delete it & recreate in `.spec.ts`
-- Keep passing tests in `.test.ts`
-- Use `npx jest <file> -t "substring"` for deprecated test execution using the same strategy above
-- Run all tests in the root workspace:  
-  → `pnpm test`
-
-# Creating tests
-
-- Use vitest (native ESM, jest-compatible)
-- Steps:
-    1. Create `path/to/__tests__/name.spec.ts` (must be `.spec.ts`)
-    2. Omit ESM mocks unless necessary
-    3. Run via vitest
-- For modules with existing `.test.ts`:
-    1. Move any failing tests → `name.spec.ts`
-    2. Add new tests → `name.spec.ts`
-    3. Leave successful tests in `.test.ts`
