# Project memory

## Verified facts

- LexAI has two clients: Chrome MV3 (repo root / WXT) and VS Code (`packages/vscode`).
- Portable core: `src/lib/providers.ts`, `actions.ts`, `types.ts`. Chrome-only: `crypto.ts`, `messaging.ts`.
- Providers: OpenAI, Anthropic, Groq, OpenRouter — routed by `callProvider` / `PROVIDER_SPECS`.
- VS Code v1: Command Palette + editor context submenu; API key in Secret Storage; prefs `lexai.provider|model|writingStyle`.
- Selection minimum length for actions: `MIN_SELECTION_LENGTH` (10) in `src/lib/actions.ts`.
- Chrome message listener must `return true` for async replies; snapshot selection before `await`.

## Conventions

- Style Chrome UI with inline styles (Tailwind not wired).
- Prefer encrypted Chrome key path; keep plaintext `apiKey` fallback until migration.
- VS Code must not import `@lib/crypto` or `@lib/messaging`.
- Root scripts: `vscode:install`, `vscode:build`, `vscode:typecheck`, `vscode:package`.

## Environment quirks

- Node 22 pinned in CI; `npx wxt prepare` required before Chrome typecheck on fresh clone.
- PowerShell may not accept `&&` — chain with `; if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }`.
