     *   **PrimeVue:** Use components directly with their standard names (e.g., `<Button>`, `<InputText>`, `<DataTable>`).
     *   **Custom Components:** Local components (e.g., `<MyCustomComponent />` defined in `src/components/MyCustomComponent.vue`) should be used directly in templates without explicit imports in `<script setup>`.
 *   **Custom Icons:** Custom SVG icons are available via `unplugin-icons` with the prefix `icon-`. Usage: `<icon-your-svg-file-name />`.
+*   **No Auto-Import Comments for Components:** When using auto-imported components (UI libraries, local components), **do not** add comments indicating they are auto-imported. Assume this behavior is known.

 *   **Auto-Imported Directories:** All exports from files within `src/stores/**` and `src/utils/**` are also auto-imported globally. Functions, variables, or stores defined and exported in these directories can be used directly without explicit import statements.
 *   **Template Usage:** Auto-import functionality also applies within the `<template>` block where appropriate (e.g., accessing store state or using certain utility functions directly).
 *   **Important:** Rely on the auto-import mechanism for the specified libraries and directories. Explicitly importing these APIs clutters the code unnecessarily.
+*   **No Auto-Import Explanation Comments:** When using auto-imported APIs (from libraries like Vue, Pinia, VueUse, or custom directories like `src/utils`, `src/stores`), simply use them directly. **Absolutely avoid adding comments that merely state an item is auto-imported** (e.g., DO NOT add comments like "// xxx is auto-imported from src/utils"). Focus comments on explaining complex logic or intent.
 
 ## ✅ Summary of Key Rules & Conventions
 
 *   **Always** use `<script setup lang="ts">`.
 *   Composition API is the **only** accepted style.
-*   Code comments **must be in Chinese**.
+*   Code comments **must be in Chinese** and explain **why/how**, not what or the build system.
 *   Vue 3 Composition API, Pinia, Vue Router (auto), VueUse functions, `consola`, and exports from `src/stores` & `src/utils` are globally available via auto-import; **do not** import them explicitly.
 *   Ant Design Vue, PrimeVue, and local `src/components` components are auto-imported; use them directly in templates without explicit imports.
+*   **Crucially: Do not add comments solely to explain that an API or component is auto-imported.** Trust the auto-import setup.
 *   Use custom SVG icons via the `<icon-name />` syntax.
 *   Maintain the specified SFC structure: `<script setup>`, `<template>`, `<style>`.
