Rspress Description Generator

Rspress description generator

The description field in Rspress frontmatter generates <meta name="description" content="..."> tags, which are used for search engine snippets, social media previews, and AI-oriented formats like llms.txt.

Step 1 — locate the docs root

1. Find the Rspress config file. Search for rspress.config.ts, .js, .mjs, or .cjs. It may be at the project root or inside a subdirectory like website/.
2. Read the config and extract the root option.

• The value might be a plain string (root: 'docs') or a JS expression (root: path.join(__dirname, 'docs')). In either case, determine the resolved directory path.
• If root is set, resolve it relative to the config file's directory.
• If root is not set, default to docs relative to the config file's directory.

1. Confirm the directory exists. If neither docs nor the configured root exists, check for doc as a fallback.

Step 2 — detect i18n structure

Rspress i18n projects place language subdirectories (e.g., en/, zh/) directly under the docs root:

docs/
├── en/
│   ├── guide/
│   └── index.md
└── zh/
    ├── guide/
    └── index.md

Check if the docs root contains language subdirectories (two-letter codes like en, zh, ja, ko, etc.). If so, process each language directory separately — the description language should match the content language.

If there are no language subdirectories, treat the entire docs root as a single-language site.

Step 3 — scan and process files

Glob for **/*.md and **/*.mdx under the docs root. Exclude:

• node_modules, build output (doc_build, .rspress, dist)
• _meta.json / _nav.json (sidebar/nav config files, not doc pages)
• **/shared/** directories (reusable snippets included via @import, not standalone pages)

For each file:

1. Read the file.
2. Check for existing `description` in frontmatter. If it exists and is non-empty, skip.
3. Check `pageType` in frontmatter. For home pages, derive the description from the hero.text / hero.tagline fields or the features list, not from body content.
4. Generate a description following the writing guidelines below.
5. Insert `description` into frontmatter:

• If the file has frontmatter with a title field, insert description on the line after title.
• If the file has frontmatter without title, insert description as the first field.
• If the file has no frontmatter block, add one:

     ---
     description: Your generated description here
     ---

YAML formatting

Most descriptions can be bare YAML strings:

description: Step-by-step guide to setting up your first Rspress site

If the description contains colons, quotes, or other special YAML characters, wrap in double quotes:

description: 'API reference for Rspress configuration: plugins, themes, and build options'

Step 4 — batch processing

For sites with many files, use parallel agent calls to process independent files simultaneously. Group by directory (e.g., all files in guide/, then all in api/) to maintain focus and consistency within each section.

After processing all files, do a quick scan to ensure no files were missed — re-glob and check for any remaining files without description.

Description writing guidelines

The description serves three audiences: search engines (Google snippet), AI systems (llms.txt, summarization), and humans (scanning search results). A good description helps all three.

Rules

• Length: 50–160 characters. Under 50 is too vague for search engines; over 160 gets truncated in snippets.
• Language: Match the document content. Chinese docs get Chinese descriptions, English docs get English descriptions.
• Be direct: State what the page covers. Avoid starting with "This document", "This page", "Learn about" — jump straight to the substance.
• Be specific: Mention concrete technologies, APIs, or concepts the page covers. "Configure Rspress plugins for search, analytics, and internationalization" beats "How to use plugins."
• No markdown: Plain text only, no formatting syntax.
