Here are a few options for describing the “使用量” (Yòngshǐyǎng) WordPress post tag, catering to different contexts and depths of detail:

**Option 1: Concise and General (Suitable for general use in a wider context)**

* **zh-HK:** 描述文章中關於資源、原料、或者功能嘅使用量或消耗量。
* **zh-TW:** 描述文章中關於資源、原料、或者功能的使用量或消耗量。 (This is practically the same as the above, just a more standard/formal writing style)

**Translation:** Describes the usage or consumption of resources, raw materials, or features discussed in the articles.

**Option 2: Slightly More Specific (If your content frequently discusses specific metrics)**

* **zh-HK:** 標記文章內嘅產品、服務或資源嘅使用量，包括數值、消耗、總量等。
* **zh-TW:** 標記文章內的产品、服务或資源的使用量，包括數值、消耗、總量等。

**Translation:** Tags articles discussing the usage of products, services, or resources, including quantities, consumption, and totals.

**Option 3: Focusing on Consumption and Cost (If applicable)**

* **zh-HK:** 針對文章討論嘅成本、消耗、或使用相關嘅數據，例如燃料、電力、或者其他資源嘅使用量。
* **zh-TW:** 針對文章討論的成本、消耗、或使用相關的數據，例如燃料、電力、或者其他資源的使用量。

**Translation:** Targets data related to costs, consumption, or usage discussed in articles, such as fuel, electricity, or the usage of other resources.

**Option 4: Developer-Focused (If the website targets developers or technical audience, or uses code samples)**

* **zh-HK:** 標記程式碼、API、或者系統功能嘅使用記錄。包含數據消耗、函式呼叫頻率等。
* **zh-TW:** 標記程式碼、API、或者系統功能的使用記錄。包含數據消耗、函數調用頻率等。

**Translation:** Tags related to the usage records of code, APIs, or system features. This includes data consumption, function call frequency, etc.

**Key Considerations When Choosing:**

* **Your Website’s Content:** The description should be relevant to the topics you frequently write about.
* **Target Audience:** Consider the technical knowledge of your readers. A more technical description is fine if your audience is technical.
* **SEO:** Think about search terms your audience might use. A description can help with search engine optimization.
* **Consistent Style:** Choose a style and stick with it for all your post tag descriptions.

I recommend selecting the most appropriate description to help categorize your articles and improve your website navigability. The first option given is often the most versatile as it keeps the scope relatively broad. You can always update the description if your needs change.
