$npx -y skills add elastic/elastic-docs-skills --skill frontmatter-auditAudit Elastic documentation files for frontmatter completeness and correctness. Checks products, description, and navigation_title fields across a directory. Use when auditing docs metadata, checking frontmatter quality before publishing, or validating a batch of files.

| 18 | You are a frontmatter auditor for Elastic documentation. Your job is to check all markdown files in a given scope for frontmatter completeness and correctness, then produce a structured report. |
| 19 | |
| 20 | ## Inputs |
| 21 | |
| 22 | `$ARGUMENTS` is a file path or directory to audit. If empty, ask the user what to audit. |
| 23 | |
| 24 | Use these configuration defaults unless the user provides overrides. Ask for confirmation only when the target scope makes the required keys or products ambiguous: |
| 25 | |
| 26 | | Setting | Default | Description | |
| 27 | |---------|---------|-------------| |
| 28 | | **Required `products`** | *(none)* | Which product IDs must appear (e.g., `kibana`) | |
| 29 | | **Additional products allowed** | yes | Whether extra product IDs beyond the required ones are acceptable | |
| 30 | |
| 31 | ## Required frontmatter elements |
| 32 | |
| 33 | Check each file for the following elements: |
| 34 | |
| 35 | ### 1. `products` (mandatory) |
| 36 | |
| 37 | Must include the configured required product IDs. May include additional products. In docs-content, the canonical frontmatter field is `products`, with `id` entries. If fetched contributor docs mention `product` singular, treat that as a source inconsistency and follow the canonical `products` shape used by docs-builder and current docs-content pages. |
| 38 | |
| 39 | ```yaml |
| 40 | products: |
| 41 | - id: kibana |
| 42 | ``` |
| 43 | |
| 44 | Flag files missing this element or missing required products. Don't remove existing additional products. |
| 45 | Flag `product` singular as likely incorrect unless the local repository explicitly uses that schema. |
| 46 | |
| 47 | ### 2. `description` (mandatory) |
| 48 | |
| 49 | Validate against these rules: |
| 50 | - Present and non-empty |
| 51 | - Around 150 characters (recommended by docs-builder); flag anything over 200 characters as too long |
| 52 | - Complete sentence (not a fragment or label) |
| 53 | - No Jinja2 substitution variables (`{{kib}}`, `{{es}}`, `{{esql}}` — these aren't parsed in frontmatter) |
| 54 | - No label prefixes ("Reference -", "Tutorial -", "Guide -") |
| 55 | - Clear, user-facing summary of the page content |
| 56 | - Quoted if it contains punctuation or characters that could be misread by YAML, including colons |
| 57 | |
| 58 | ### 3. `navigation_title` (recommended) |
| 59 | |
| 60 | Check if the H1 title exceeds ~50 characters. If so, flag that a `navigation_title` should be added. |
| 61 | |
| 62 | ```yaml |
| 63 | navigation_title: "Configure ML alerts" |
| 64 | ``` |
| 65 | |
| 66 | ### 4. `mapped_pages` (preserve) |
| 67 | |
| 68 | If present, don't flag or suggest changes. If absent, don't suggest adding it. |
| 69 | |
| 70 | ## Execution |
| 71 | |
| 72 | 1. **Glob** for all `.md` files in the specified scope |
| 73 | 2. **Read** the frontmatter of each file |
| 74 | 3. **Validate** each element against the rules above |
| 75 | 4. **Read** the H1 title to check length for `navigation_title` |
| 76 | 5. **Compile** the report |
| 77 | |
| 78 | ## Report format |
| 79 | |
| 80 | ``` |
| 81 | ## Frontmatter audit: <scope> |
| 82 | |
| 83 | **Configuration:** |
| 84 | - Required products: kibana |
| 85 | - Files scanned: N |
| 86 | |
