+title: Conditional Validation
+description: Learn how to run the Starlight Spell Checker plugin conditionally to avoid unnecessary cache invalidation.
+---
+
+When using the Starlight Spell Checker plugin with the [Content Layer API](https://docs.astro.build/en/guides/content-collections), the plugin will automatically invalidate the content layer cache so that all words can be properly validated.
+To avoid unnecessary cache invalidation, it is recommended to conditionally use the plugin only when necessary.
+
+## Run the plugin conditionally
+
+By default, when adding the plugin to your Starlight configuration in the [`plugins`](https://starlight.astro.build/reference/configuration/#plugins) array, the plugin will run for every build.
+
+Instead of running the plugin for every build, you can conditionally use the plugin based on an environment variable.
+In the following example, the plugin will only run when the `CHECK_SPELLING` environment variable is set.
+
+```diff lang="js"
+// astro.config.mjs
+import starlight from '@astrojs/starlight'
+import { defineConfig } from 'astro/config'
+import starlightSpellChecker from 'starlight-spell-checker'
+
+export default defineConfig({
+  integrations: [
+    starlight({
+-      plugins: [starlightSpellChecker()],
++      plugins: process.env.CHECK_SPELLING ? [starlightSpellChecker()] : [],
+      title: 'My Docs',
+    }),
+  ],
+})
+```
+
+To run the plugin only when the `CHECK_SPELLING` environment variable is set, you can add the following script to your `package.json` file:
+
+```json title="package.json"
+{
+  "scripts": {
+    "spellcheck": "CHECK_SPELLING=true astro build"
+  }
+}
+```
+
+The spell check script can be used on CI pipelines to validate internal words in a dedicated workflow while deployment builds can skip the link validation step.
