+# Skill: `new-page-scaffold`
+
+Scaffold a new documentation page with correct frontmatter and directory
+structure for `opentelemetry.io`.
+
+## Parameters
+
+- `title`: The title of the page.
+- `description`: A brief description for SEO and site search.
+- `path`: The target path relative to `content/en/docs/`.
+
+## Steps
+
+1.  **Validate path**: Ensure the target directory exists under
+    `content/en/docs/`.
+2.  **Determine filename**: Use kebab-case for the filename. If it's a section
+    landing page, use `_index.md`.
+3.  **Generate frontmatter**:
+    ```yaml
+    ---
+    title: <title>
+    description: <description>
+    weight: <calculated-weight>
+    ---
+    ```
+4.  **Calculate weight**: Check existing files in the directory to determine the
+    next logical `weight` (increment by 10 or 5).
+5.  **Create file**: Write the scaffolding to the calculated path.
+6.  **Verify**: Run `npm run check:markdown` on the new file.

+# Skill: `review-content`
+
+Review `opentelemetry.io` documentation content for compliance with the OTel
+style guide and markdown standards.
+
+## Parameters
+
+- `path`: The path to the markdown file to review.
+
+## Steps
+
+1.  **Format and lint check**:
+    - Run `npm run check:markdown -- <path>` to verify basic markdown
+      formatting.
+    - Run `npm run check:text -- <path>` for terminology and textlint rules.
+2.  **Style guide alignment**:
+    - **Alerts**: Verify alert types use the standard `> [!NOTE]`, `> [!TIP]`,
+      `> [!IMPORTANT]`, `> [!WARNING]`, or `> [!CAUTION]` syntax.
+    - **Headings**: Ensure each page has exactly one `H1` and that heading
+      levels follow a logical hierarchy.
+    - **Heading IDs**: Check if headings have explicit IDs (e.g.,
+      `## Heading {#id}`) as required by the site's Hugo configuration.
+    - **Inclusive language**: Ensure the content follows inclusive language
+      principles (e.g., avoiding "master/slave", "whitelist/blacklist").
+3.  **Frontmatter validation**:
+    - Verify mandatory fields: `title`, `description`.
+    - Check for appropriate `weight` if the page is part of a sequence.
+4.  **Links and images**:
+    - Run `npm run check:links -- <path>` to verify all links are valid.
+    - For images, ensure they have descriptive alt text.
+5.  **Summarize results**: Provide a clear list of violations and suggested
+    fixes.

+# Skill: `setup-localization`
+
+Automate the "New localizations" onboarding process for `opentelemetry.io`.
+
+## Parameters
+
+- `language_name`: The name of the language (e.g., "Hindi").
+- `language_code`: ISO 639-1 language code (e.g., "hi").
+- `mentor_handle`: GitHub handle of the localization mentor.
+- `contributor_handles`: List of GitHub handles for initial contributors.
+
+## Steps
+
+1.  **Prepare Hugo config**:
+    - Update `config/_default/hugo.yaml`: Add the new language to the
+      `languages` block.
+    - Update `config/_default/module-template.yaml`: Add a content mount for the
+      new language.
+2.  **Setup spelling support**:
+    - Check for an available `@cspell/dict-<language_code>` NPM package.
+    - If available, install as a dev dependency
+      (`npm install --save-dev @cspell/dict-<language_code>`).
+    - Create `.cspell/<language_code>-words.txt` for site-local words.
+    - Update `.cspell.yml` to import the new dictionary and define the local
+      word file.
+3.  **Localize homepage**:
+    - Create `content/<language_code>/_index.md`.
+    - Scaffold the file with basic frontmatter including `title` and
+      `description` in the target language.
+4.  **Draft initial localization issue**:
+    - Use the template from `content/en/docs/contributing/localization.md`
+      section "Localization kickoff".
+    - Populate fields: Language info, Locale team info, and OTel maintainer
+      checklist.
+5.  **Verify**:
+    - Build the site locally (`npm run build`) to ensure Hugo configuration is
+      valid.
+    - Run `npm run check:i18n -- content/<language_code>` to check
+      synchronization status.
