Frontmatter Description

Check and optimize MetaDescription frontmatter fields in markdown documentation files. Produces actionable fixes for descriptions that violate the rules below.

When to Use

• Adding or editing a documentation page and need to write a MetaDescription.
• Auditing existing pages for SEO or discoverability improvements.
• Asked to check, review, or optimize frontmatter descriptions.
• Editing content articles and want to ensure the MetaDescription reflects the updated content.

Rules

Every MetaDescription value must satisfy all of the following:

Procedure

1. Identify target files

Determine which files to check:

• If given specific files, use those.
• If asked to audit a folder (e.g., docs/copilot/), find all .md files in that folder recursively.
• Skip files that have no YAML frontmatter (e.g., README.md files without --- delimiters).

2. Extract and validate

For each file, read the YAML frontmatter and check the MetaDescription field:

1. Missing — Flag if MetaDescription is absent.
2. Length — Flag if the value exceeds 160 characters. Report the current length.
3. Voice — Flag if it contains "you can", "users can", "this page explains", or similar reader-addressing phrases.
4. Tone — Flag if the description is a fragment, a label, or passive rather than action-oriented.
5. Context — Flag if the description does not mention the relevant feature or tool.
6. Forbidden words — Flag any occurrence of "teaching", "enable", "disable", or condescending terms.
7. Colons — Flag any : character in the value.
8. Versions — Flag any version numbers (e.g., "v1.90", "VS Code 1.90").
9. Plain text — Flag Jinja2 variables ({{...}}), HTML tags, or Markdown formatting.

3. Report findings

Present results as a table:

| File | Issue | Current value | Suggested fix |
|------|-------|---------------|---------------|

• Group by file path.
• For each issue, provide the current MetaDescription and a rewritten suggestion that passes all rules.
• If a description passes all checks, omit it from the table (or mark it as passing if the user asked for a full report).

4. Apply fixes (when asked)

• Edit the MetaDescription value in the YAML frontmatter.
• Do not change any other frontmatter fields.
• Do not alter the page body content.
• Verify the fix passes all rules before applying.

Examples

Good descriptions:

• Get AI-powered inline suggestions from GitHub Copilot in VS Code, including ghost text completions and next edit suggestions.
• Configure and manage extensions in Visual Studio Code to customize your development environment.
• Debug Python applications in Visual Studio Code with breakpoints, variable inspection, and integrated terminal output.
